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. 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) 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 and then back to OFF. All these features will work when the key is in the ON or ACCESSORY positions. 125
