yellowblue Front Reading Lamps Trunk Lamp When you open the trunk to its full open position, a lamp will come on inside the trunk. This lamp will automatically turn off when the trunk is closed. Battery Rundown Protection This feature automatically shuts off the interior lamps if any are left on for more than 10 minutes when the ignition is off. This will keep your battery from running down. This feature also shuts off the exterior lamps if they are left on for more than 10 minutes when the ignition is off. You may override this feature for the exterior lamps by turning the lamps off and then back on after the ignition is turned to off. If you do this, the exterior lamps will stay on until you manually turn them off. If the feature is enabled for the interior and exterior lamps, all lamps should turn off at approximately the same time. These lamps and the interior courtesy lamps will come on when you open a door, and turn off when you turn the ignition on. To turn on the reading lamps when the doors are closed, press the button behind the lamp you want on. Press it again to turn the lamp off. 2-45
