Courtesy Lamps When any door or the trunk lid is opened, the interior lamps will go on unless it's bright outside. You can also turn on the courtesy lamps by pressing the interior lamp button on the right side of the instrument panel cluster. Reading Lamps Your inside rearview mirror includes two reading lamps. The lamps will go on when a door is opened. When the doors are closed, each lamp can be turned on individually by pressing the button for that lamp. Battery Run-Down Protection Your vehicle has a feature to help prevent you from draining the battery in case the underhood lamp, vanity mirror lamps, cargo lamps, reading lamps, console or glove box lamps are accidentally left on or in case something is plugged into the accessory power outlet or cigarette lighter. If you leave any of these lamps on, they will automatically time-out after about 20 minutes. To reset it, all of the above lamps must be turned off or the ignition key must be in ON. Exit/Entry Lighting With entry lighting, the interior lamps will come on when entering the vehicle. The interior lamps will come on for about 20 seconds when the engine is turned off or a door is ajar. You can turn exit and entry lighting off by quickly turning the headlamps on and off or by quickly turning the courtesy lamps on and off. 3-28
