Engine Oil
To ensure proper engine performance and long life, careful attention must be paid to engine oil.
Following these simple, but important steps will help protect your investment:
• Always use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.
• Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.
• Change the engine oil at the appropriate time. See Engine Oil Life System.
• Always dispose of engine oil properly. See “What to Do with Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview for the location of the engine oil dipstick.
Obtaining an accurate oil level reading is essential:
1. If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan.
Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.
2. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way.
Remove it again, keeping the tip down, and check the level.
When to Add Engine Oil

When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications.
Notice:
Do not add too much oil.
Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If you find that you have an oil level above the operating range, i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. You should drain out the excess oil or limit driving of the vehicle and seek a service professional to remove the excess amount of oil.
See Engine Compartment Overview for the location of the engine oil fill cap.
Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil depends on both the proper oil specification and viscosity grade.
See Recommended Fluids and Lubricants.
Specification
Use and ask for licensed engine oils with the dexos1™ approved certification mark. Engine oils meeting the requirements for the vehicle should have the dexos1 approved certification mark. This certification mark indicates that the oil has been approved to the dexos1 specification.

Notice:
Failure to use the 
recommended engine oil or 
equivalent can result in engine 
damage not covered by the 
vehicle warranty. Check with your 
dealer or service provider on 
whether the oil is approved to the 
dexos1 specification.
Viscosity Grade
SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50.
If in an area of extreme cold, where the temperature falls below −20°F (−29°C), an SAE 0W-30 oil should be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, always select an oil that meets the dexos1 specification or equivalent. See “Specification” for more information.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The recommended oils with the dexos specification and displaying the dexos certification mark are all that is needed for good performance and engine protection.
Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven.
Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.
When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. See Engine Oil Messages.
Change the oil as soon as possible within the next 1 000 km (600 mi).
It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level.
If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change.
Remember to reset the oil life system whenever the oil is changed.
How to Reset the Engine Oil Life System
Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. To reset the system:
1. Turn the ignition to ON/RUN with the engine off.
2. Press the DIC MENU button on the turn signal lever to enter the Vehicle Information Menu. Use the thumbwheel to scroll through the menu items until you reach REMAINING OIL LIFE.
3. Press the SET/CLR button to reset the oil life at 100%.
4. Turn the ignition to LOCK/OFF.
The system is reset when the CHANGE ENGINE OIL SOON message is off and the REMAINING OIL LIFE 100% message is displayed.
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
Automatic Transmission Fluid
How to Check Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer service department and have it repaired as soon as possible.
There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, you should have this done at your dealer service department. Contact your dealer for additional information or the procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information.
Change the fluid and filter at the intervals listed in Maintenance Schedule, and be sure to use the fluid listed in Recommended Fluids and Lubricants.
Engine Air Cleaner/Filter
The engine air cleaner/filter is located in the engine compartment on the driver side of the vehicle.
See Engine Compartment Overview for more information on location.
When to Inspect the Engine Air Cleaner/Filter
Inspect the air cleaner/filter at the scheduled maintenance intervals and replace it at the first oil change after each 80 000 km (50,000 mi) interval. See Maintenance Schedule for more information.
If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.
How to Inspect the Engine Air Cleaner/Filter
To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains covered with dirt, a new filter is required.
To inspect or replace the engine air cleaner/filter:
2.4L L4 Engine

2.4L L4 Engine
1. Remove the six screws on top of the engine air cleaner/filter housing.
2. Lift the filter cover housing away from the engine air cleaner/filter housing.
3. Pull out the filter.
4. Inspect or replace the engine air cleaner/filter.
5. Lower the filter cover housing toward the engine.
6. Install the six screws on the top of the housing to lock the cover in place.
3.6L V6 Engine

3.6L V6 Engine
1. Remove the screws on top of the engine air cleaner/filter housing.
2. Lift the filter cover housing away from the engine.
3. Pull out the filter.
4. Inspect or replace the engine air cleaner/filter.
5. Lower the filter cover housing toward the engine.
6. Install the screws on the top of the housing to lock the cover in place.
WARNING!
Operating the engine with the air 
cleaner/filter off can cause you or 
others to be burned. The air 
cleaner not only cleans the air; it 
helps to stop flames if the engine 
backfires. Use caution when 
working on the engine and do not 
drive with the air cleaner/filter off.
Notice:
If the air cleaner/filter is 
off, dirt can easily get into the 
engine, which could damage it.
Always have the air cleaner/filter 
in place when you are driving.

WARNING!
An electric engine cooling fan 
under the hood can start up even 
when the engine is not running 
and can cause injury. Keep 
hands, clothing, and tools away 
from any underhood electric fan.
WARNING!
Heater and radiator hoses, and 
other engine parts, can be very 
hot. Do not touch them. If you do, 
you can be burned.
Do not run the engine if there is a 
leak. If you run the engine, it 
could lose all coolant. That could 
cause an engine fire, and you 
could be burned. Get any leak 
fixed before you drive the vehicle.
Notice:
Using coolant other than 
DEX-COOL® can cause premature 
engine, heater core, or radiator 
corrosion. In addition, the engine 
coolant could require changing 
sooner. Any repairs would not be 
covered by the vehicle warranty.
Always use DEX-COOL 
(silicate-free) coolant in the 
vehicle.
Engine Coolant
The cooling system in the vehicle is filled with DEX-COOL® engine coolant mixture. See Recommended Fluids and Lubricants and Maintenance Schedule for more information.
The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating.
What to Use
WARNING!
Adding only plain water or some 
other liquid to the cooling system 
can be dangerous. Plain water 
and other liquids can boil before 
the proper coolant mixture will.
The coolant warning system is set 
for the proper coolant mixture.
With plain water or the wrong 
mixture, the engine could get too 
hot but you would not get the 
overheat warning. The engine 
could catch fire and you or others 
could be burned. Use a 
50/50 mixture of clean, drinkable 
water and DEX-COOL coolant for 
non-eAssist engine(s). Use a 
50/50 mixture of deionized water 
and DEX-COOL coolant for 
eAssist engine(s).
Use a 50/50 mixture of deionized water or clean, drinkable water and DEX-COOL coolant. If using this mixture, nothing else needs to be added.
This mixture:
• Gives freezing protection down to −37°C (−34°F), outside temperature.
• Gives boiling protection up to 129°C (265°F), engine temperature.
• Protects against rust and corrosion.
• Will not damage aluminum parts.
• Helps keep the proper engine temperature.
Notice:
If an improper coolant 
mixture is used, the engine could 
overheat and be badly damaged.
The repair cost would not be 
covered by the vehicle warranty.
Too much deionized water or 
clean, drinkable water in the 
mixture can freeze and crack the 
engine, radiator, heater core, and 
other parts.
Never dispose of engine coolant by putting it in the trash, pouring it on the ground, or into sewers, streams, or bodies of water. Have the coolant changed by an authorized service center, familiar with legal requirements regarding used coolant disposal. This will help protect the environment and your health.
Checking Coolant
The vehicle must be on a level surface when checking the coolant level.
Check to see if coolant is visible in the coolant surge tank. If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down.
If coolant is visible but the coolant level is not at or above the mark pointed to, add a 50/50 mixture of deionized water or clean drinkable water and DEX-COOL coolant.
Be sure the cooling system is cool before this is done.
If no coolant is visible in the coolant surge tank, add coolant as follows:
How to Add Coolant to the Coolant Surge Tank
WARNING!
You can be burned if you spill 
coolant on hot engine parts.
Coolant contains ethylene glycol 
and it will burn if the engine parts 
are hot enough. Do not spill 
coolant on a hot engine.
Notice:
This vehicle has a 
specific coolant fill procedure.
Failure to follow this procedure 
could cause the engine to 
overheat and be severely 
damaged.
WARNING!
An electric engine cooling fan 
under the hood can start up even 
when the engine is not running 
and can cause injury. Keep 
hands, clothing, and tools away 
from any underhood electric fan.
WARNING!
Steam and scalding liquids from a 
hot cooling system can blow out 
and burn you badly. They are 
under pressure, and if you turn 
the surge tank pressure 
cap—even a little—they can 
come out at high speed. Never 
turn the cap when the cooling 
system, including the surge tank 
pressure cap, is hot. Wait for the 
cooling system and surge tank 
pressure cap to cool if you ever 
have to turn the pressure cap.

The coolant surge tank pressure cap can be removed when the cooling system, including the surge tank pressure cap and upper radiator hose, is no longer hot.
1. Turn the pressure cap slowly counterclockwise. If a hiss is heard, wait for that to stop.
A hiss means there is still some pressure left.
2. Keep turning the cap and remove it.

3. Fill the coolant surge tank with the proper mixture to the mark pointed to on the front of the coolant surge tank.
4. With the coolant surge tank cap off, start the engine and let it run until the upper radiator hose starts getting hot. Watch out for the engine cooling fans. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the mark pointed to on the front of the coolant surge tank.
5. Replace the cap. Be sure the cap is hand–tight and fully seated.
Notice:
If the pressure cap is not 
tightly installed, coolant loss and 
possible engine damage may 
occur. Be sure the cap is properly 
and tightly secured.
Engine Overheating
2.4L L4 Engine
There is a engine coolant temperature warning light on the instrument panel cluster that indicates an overheated engine condition. See Engine Coolant Temperature Warning Light for more information.
3.6L V6 Engine
There is a coolant temperature gauge and a engine coolant temperature warning light on the instrument panel cluster that indicate an overheated engine condition. See Engine Coolant Temperature Gauge and Engine Coolant Temperature Warning Light for more information.
If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Assistance Program (U.S. and Canada) or Roadside Assistance Program (Mexico).
If the decision is made to lift the hood, make sure the vehicle is parked on a level surface.
Then check to see if the engine cooling fans are running. If the engine is overheating, the fans should be running. If not, do not continue to run the engine and have the vehicle serviced.
Notice:
Engine damage from 
running the engine without 
coolant is not covered by the 
warranty.
If Steam Is Coming from the Engine Compartment
See Overheated Engine Protection Operating Mode for information on driving to a safe place in an emergency.
If No Steam Is Coming from the Engine Compartment
If an engine overheat warning is displayed but no steam can be seen or heard, the problem might not be too serious. Sometimes the engine can get a little too hot when the vehicle:
• Climbs a long hill on a hot day.
• Stops after high-speed driving.
• Idles for long periods in traffic.
• Tows a trailer.
If the overheat warning displays with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and let the engine idle.
2.4L L4 Engine
If the engine coolant temperature warning light no longer displays, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes. Keep a safe vehicle distance from the vehicle in front.
If the warning does not come back on, continue to drive normally.
3.6L V6 Engine
If the temperature overheat gauge is no longer in the overheat zone or an engine coolant temperature warning light no longer displays, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes.
Keep a safe vehicle distance from the vehicle in front. If the warning does not come back on, continue to drive normally.
If the warning continues, pull over, stop, and park the vehicle right away.
If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see Overheated Engine Protection Operating Mode.
Overheated Engine Protection Operating Mode
This emergency operating mode allows the vehicle to be driven to a safe place in an emergency situation. If an overheated engine condition exists, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is significant loss in power and engine performance.
2.4L L4 Engine
The engine coolant temperature warning light comes on the instrument panel, to indicate the vehicle has entered overheated engine protection operating mode.
Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided.
3.6L V6 Engine
The engine coolant temperature warning light comes on the instrument panel, to indicate the vehicle has entered overheated engine protection operating mode.
The temperature gauge also indicates an overheat condition exists. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided.
Power Steering Fluid (2.4L L4 Engine)
The vehicle has electric power steering and does not use power steering fluid.
Power Steering Fluid (3.6L V6 Engine)

See Engine Compartment Overview for information on the location of the power steering fluid reservoir.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid unless a leak is suspected in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
How to Check Power Steering Fluid
Check the level after the vehicle has been driven for at least 20 minutes so the fluid is warm.
To check the power steering fluid:
1. Turn the ignition to LOCK/OFF and let the engine compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and pull it straight up.
4. Wipe the dipstick with a clean rag.
5. Replace the cap and completely tighten it.
6. Remove the cap again and look at the fluid level on the dipstick.

When the engine is hot, the level should be at the hot MAX level.
When the engine is cold, the fluid level should be between MIN and MAX on the dipstick.
What to Use
To determine what kind of fluid to use, see Recommended Fluids and Lubricants. Always use the proper fluid.
Washer Fluid
What to Use
When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Adding Washer Fluid

Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview for reservoir location.
Notice. When using concentrated 
washer fluid, follow the 
manufacturer's instructions 
for adding water.
• Do not mix water with 
ready-to-use washer fluid.
Water can cause the solution 
to freeze and damage the 
washer fluid tank and other 
parts of the washer system.
Also, water does not clean as 
well as washer fluid.
• Fill the washer fluid tank only 
three-quarters full when it is 
very cold. This allows for 
fluid expansion if freezing 
occurs, which could damage 
the tank if it is 
completely full.
• Do not use engine coolant 
(antifreeze) in the windshield 
washer. It can damage the 
windshield washer system 
and paint.
Brakes
This vehicle has disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed.
The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.
WARNING!
The brake wear warning sound 
means that soon the brakes will 
not work well. That could lead to 
a crash. When the brake wear 
warning sound is heard, have the 
vehicle serviced.
Notice:
Continuing to drive with 
worn-out brake pads could result 
in costly brake repair.
Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes.
Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications.
Brake linings should always be replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service might be required.
Brake Adjustment
Every time the brakes are applied, with or without the vehicle moving, the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced, be sure to get new, approved replacement parts.
If this is not done, the brakes might not work properly. For example, installing disc brake pads that are wrong for the vehicle, can change the balance between the front and rear brakes — for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed.
Brake Fluid

The brake master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview for the location of the reservoir.
There are only two reasons why the brake fluid level in the reservoir might go down:
• The brake fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up.
• A fluid leak in the brake hydraulic system can also cause a low fluid level. Have the brake hydraulic system fixed, since a leak means that sooner or later the brakes will not work well.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake hydraulic system.
WARNING!
If too much brake fluid is added, it 
can spill on the engine and burn, 
if the engine is hot enough. You 
or others could be burned, and 
the vehicle could be damaged.
Add brake fluid only when work is 
done on the brake hydraulic 
system.
When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light.
What to Add
Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants.
Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.
WARNING!
With the wrong kind of fluid in the 
brake hydraulic system, the 
brakes might not work well. This 
could cause a crash. Always use 
the proper brake fluid.
Notice 
. Using the wrong fluid can 
badly damage brake 
hydraulic system parts. For 
example, just a few drops of 
mineral-based oil, such as 
engine oil, in the brake 
hydraulic system can 
damage brake hydraulic 
system parts so badly that 
they will have to be replaced.
Do not let someone put in 
the wrong kind of fluid.
• If brake fluid is spilled on the 
vehicle's painted surfaces, 
the paint finish can be 
damaged. Be careful not to 
spill brake fluid on the 
vehicle. If you do, wash it off 
immediately.
Battery
This vehicle has a standard 12-volt battery. Refer to the replacement number on the original battery label when a new standard 12-volt battery is needed.
eAssist vehicles also have a high voltage battery. Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the high voltage battery.

While parked, and with the parking brake set, try to turn the ignition to LOCK/OFF in each shift lever position.
• The ignition should turn to LOCK/OFF only when the shift lever is in P (Park).
• With the key access ignition system, the ignition key should come out only in LOCK/OFF.
See Ignition Positions (Key Access) or Ignition Positions (Keyless Access).
Contact your dealer if service is required.
Park Brake and P (Park) Mechanism Check
WARNING!
When you are doing this check, 
the vehicle could begin to move.
You or others could be injured and property could be damaged.
Make sure there is room in front of the vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.
• To check the parking brake's holding ability: With the engine running and the transmission in N (Neutral), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.
• To check the P (Park) mechanism's holding ability:
With the engine running, shift to P (Park). Then release the parking brake followed by the regular brake.
Contact your dealer if service is required.
Wiper Blade Replacement
Windshield wiper blades should be inspected for wear and cracking.
See Maintenance Schedule for more information.
Replacement blades come in different types and are removed in different ways. For proper type and length, see Maintenance Replacement Parts.
To replace the windshield wiper blade:
1. Pull the windshield wiper assembly away from the windshield.

2. Lift up on the latch in the middle of the wiper blade where the wiper arm attaches.
3. With the latch open, pull the wiper blade down toward the windshield far enough to release it from the J-hooked end of the wiper arm.
4. Remove the wiper blade.
Allowing the wiper blade arm to touch the windshield when no wiper blade is installed could damage the windshield. Any damage that occurs would not be covered by the vehicle warranty. Do not allow the wiper blade to touch the windshield.
5. Reverse Steps 1 through 3 for wiper blade replacement.
