Dome Lamp The dome lamp will come on when you open a door. You can also turn the dome lamp on by turning the thumbwheel all the way up. In this position, the dome lamp will remain on whether a door is opened or closed. Accessory Power Outlets Your vehicle may have an accessory power outlet. With accessory power outlets you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. Your vehicle may have two accessory power outlets located on the lower part of the instrument panel below the climate control system and there may be one located on the rear of the center console. A small cap must be pulled down to access an accessory power outlet. When not using an outlet be sure to cover it with the protective cap. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage rating. Certain electrical accessories may not be compatible with the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer for additional information on accessory power outlets. E (Dome Override): Press this button, located below the exterior lamp control, to turn the dome lamp off even when a door is opened. To return the lamp to automatic operation, press the 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. Battery Run-Down Protection This feature shuts off the dome lamp if it is left on for more than 20 minutes when the ignition is in LOCK. This will keep your battery from running down. 3-16
