Automatic Transmission Operation
The automatic transmission has 6 forward speeds and one reverse speed. Gear speeds are selected automatically, depending on the position of the shift lever.
✽ NOTICE
The first few shifts on a new vehicle, or after the battery has been disconnected, may be somewhat harsh. This is normal, and the shift sequence will adjust after the TCM (Transmission Control Module) or PCM (Powertrain Control Module) has shifted several times.
For smooth operation, depress the brake pedal and press the release button when shifting from N (Neutral) to a forward or reverse gear.
WARNING! Leaving the Vehicle
Before leaving the driver's seat, always make sure the shift lever is in P (Park); then fully apply the parking brake and turn off the engine. Do not use P instead of the parking brake. Always make sure the shift lever is locked in P and fully apply the parking brake. Failure to observe these precautions may result in sudden vehicle movement.
CAUTION - Transmission
To prevent transmission damage, do not race the engine in R (Reverse) or any forward gear position with the brakes applied. The transmission may be damaged if you shift into P (Park) while the vehicle is moving.
When stopped on a slope, do not hold the vehicle with engine power. Use the service brake or the parking brake.
