When the DRL are on, only your DRL lamps will be on. The taillamps, sidemarker and other lamps won't be on. The instrument panel won't be lit up either. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps. As with any vehicle, you should turn on the regular headlamp system when you need it. Interior Lamps Instrument Panel Brightness Control The thumbwheel for this feature is located next to the exterior lamps control. (Instrument Panel Lights): Turn the thumbwheel, located next to the exterior lamps control, up or down to brighten or dim the instrument panel lights and the radio display. This will only work if the headlamps or parking lamps are on. To turn on the dome lamps, with the vehicle doors closed, turn the thumbwheel all the way up. Off-Road Lamps (If Equipped) The off-road lamps button is located on the overhead console. To use the lamps, the engine must be running with the transmission in a drive gear. Remove the covers from the lamps and press the button to turn the off road lamps on. Press the button again to turn them off. An indicator light will glow near the button when the lamps are on. The off-road lamps will be cancelled when the ignition is turned off. If you still want to use the lamps after you restart the vehicle, you will need to press the off-road lamp button again. Exit Lighting With exit lighting, the interior lamps will come on when you remove the key from the ignition. The lamps will not come on if the dome override button is pressed in. See "Dome Lamps" later in this section for more information on dome override. 2-51
