Dome Lamp The dome lamp will come on when you open either front door. You can also turn the dome lamps on by turning the instrument panel brightness thumbwheel, located next to the exterior lamps control, all the way up to the second notch. In this position, the dome lamps will remain on whether a door is opened or closed. You can use the DOME OVERRIDE button, located below the exterior lamps control, to set the dome lamps to come on automatically when either front door is opened, or to remain off. To turn the lamps off, press the button in. With the button in, the dome lamps will remain off when either front door is opened. To return the lamps to automatic operation, press the button again and return it to the out position. With the button in this position, the dome lamps will come on when you open either front door. This will override the illuminated entry feature, unless you use your remote keyless entry transmitter (if equipped) to unlock the vehicle. Battery Rundown Protection This feature shuts off the dome, courtesy, vanity, reading, glove box, cargo and underhood lamps if they are left on for more than 20 minutes when the ignition is off. This will keep your battery from running down. If the battery rundown protection shuts off the interior lamps, it may be necessary to do one of the following to return it to normal operation: • Shut off all lamps and close all doors, or • turn the ignition key to RUN. Accessory Power Outlets Your vehicle may be equipped with an accessory power outlet. With accessory power outlets you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. There may be an accessory power outlet located near the center of the vehicle on the lower part of the instrument panel. 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. 3-16
