Key In the Ignition Never leave your vehicle with the keys inside, as it is an easy target for joy riders or thieves. If you leave the key in the ignition and park your vehicle, a chime will sound when you open the driver's door. Always remember to remove your key from the ignition and take it with you. This will lock your ignition and transmission. Also, always remember to lock the doors. The battery could be drained if you leave the key in the ignition while your vehicle is parked. You may not be able to start your vehicle after it has been parked for an extended period of time. Power to the windows and sunroof will work up to 10 minutes or until a door is opened. The radio continues to work for 10 minutes or until the driver's door is opened. For an additional 10 minutes of operation, close all the doors and turn the key to ON/RUN and then back to LOCK/OFF. All these features will work when the key is in the ON/RUN or ACC/ACCESSORY positions. Starting the Engine Move your shift lever to PARK (P) or NEUTRAL (N). Your engine will not start in any other position - this is a safety feature. To restart when you are already moving, use NEUTRAL (N) only. Notice: Do not try to shift to PARK (P) if your vehicle is moving. If you do, you could damage the transmission. Shift to PARK (P) only when your vehicle is stopped. Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the ignition key is turned off: • Audio System • Power Windows • Sunroof (if equipped) 2-27
