Kia Optima: Vehicle break-in process - Introduction - Kia Optima Owners ManualKia Optima: Vehicle break-in process

No special break-in period is needed. By following a few simple precautions for the first 1,000 km (600 miles) you may add to the performance, economy and life of your vehicle.

• Do not race the engine.

• While driving, keep your engine speed (rpm, or revolutions per minute) between 2,000 rpm and 4,000 rpm.

• Do not maintain a single speed for long periods of time, either fast or slow.

Varying engine speed is needed to properly break-in the engine.

• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.

• Don't let the engine idle longer than 3 minutes at one time.

• Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
