Delayed Exit Lighting This feature illuminates the interior for a period of time after the key is removed from the ignition. The ignition must be off for delayed exit lighting to work. When the key is removed, interior illumination will activate and remain on until one of the following occurs: The ignition is moved to ON, the power door locks are activated, or an illumination period of 25 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on because a door is open. Dome Lamp If your vehicle has this feature, the dome lamp will come on when you open a door. You can also turn this lamp on by turning the exterior lamps control clockwise as far as it will go. Vehicles that have the optional sunroof do not have a dome lamp. Battery Rundown Protection Your vehicle has a feature to help prevent you from draining the battery in case you accidentally leave on the interior courtesy lamps, reading/map lamps, visor vanity lamps, trunk lamp or glove box lamps. If you leave any of these lamps on, they will automatically turn off after 10 minutes, if the ignition is moved to OFF. The lamps won't come back on again until you do the following: Turn the ignition on,or turn the exterior lamps control off, then on again. If your vehicle has less than 15 miles (25 km) on the odometer, the battery saver will turn off the lamps after only three minutes. Battery rundown protection will also work if the headlamps are left on. After having been left on for 10 minutes, the headlamps and the parking lamps will flash three times. They will remain on for one more minute before being turned off automatically. Parade Dimming The instrument panel has an added feature called parade mode. This feature prohibits the dimming of your instrument panel displays during the daylight while the headlamps are on so that you'll still be able to see the displays. Reading Lamps Your vehicle may be equipped with reading lamps that are located on the assist handles in the headliner. These lamps and the interior courtesy lamps come on when any door is opened. Press the lens to turn them on. Press it again to turn them off. 3-18
