Automatic Transmission

Move the shift lever to P (Park) or N (Neutral). The engine will not start in any other position. To restart the engine when the vehicle is already moving, use N (Neutral) only.

If the vehicle has the keyless access system, your foot must be on the brake pedal to start the engine. To rotate the ignition control knob, put your foot on the brake pedal and turn the ignition control knob to the START position. If the ignition control knob does not turn, try pushing the knob in and turning again. When the engine begins cranking, let go of the ignition control knob, it will return to the ON/RUN position.

If the transmitter is not in the vehicle or something is interfering with the transmitter, the Driver Information Center (DIC) will display ELECTRONIC KEY NOT DETECTED. See Driver Information Center (DIC) for more information.

If the battery in the keyless access transmitter needs replacing, the DIC displays REPLACE BATTERY IN REMOTE KEY.

The vehicle can still be driven.

See Battery Replacement under Remote Keyless Entry (RKE) System Operation (Keyless Access) or Remote Keyless Entry (RKE) System Operation (Key Access) for more information.

Notice: Do not try to shift to P (Park) if the vehicle is moving.
If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.
