Buick LaCrosse: Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System (TPMS).
The TPMS is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitor the air pressure in the tires and transmits the tire pressure readings to a receiver located in the vehicle.
When a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning light located on the instrument cluster.
If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the tire loading information label. See Vehicle Load Limits.
A message to check the pressure in a specific tire displays in the Driver Information Center (DIC). The low tire pressure warning light and the DIC warning message come on at each ignition cycle until the tires are inflated to the correct inflation pressure. Using the DIC, tire pressure levels can be viewed. For additional information and details about the DIC operation and displays see Driver Information Center (DIC).
The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This could be an early indicator that the air pressure is getting low and needs to be inflated to the proper pressure.
A Tire and Loading Information label, attached to your vehicle, shows the size of the original equipment tires and the correct inflation pressure for the tires when they are cold. See Vehicle Load Limits, for an example of the Tire and Loading Information label and its location. Also see Tire Pressure.
The TPMS can warn about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection, Tire Rotation and Tires.
Notice:
Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
covered by the vehicle warranty.
Always use only the
GM-approved tire sealant
available through your dealer or
included in the vehicle.
Factory-installed Tire Inflator Kits use a GM approved liquid tire sealant. Using non-approved tire sealants could damage the TPMS sensors. See Tire Sealant and Compressor Kit (With Pressure Relief Button) or Tire Sealant and Compressor Kit (With Pressure Deflation Button) for information regarding the inflator kit materials and instructions.
