6-6 Lighting Dome Lamps The dome lamps come on when any door is opened. They turn off after all the doors are closed. The dome lamps can also be turned on by turning the instrument panel brightness knob, located on the instrument panel to the left of the steering column, clockwise to the farthest position. In this position, the dome lamps remain on whether a door is opened or closed. Lighting Features Entry/Exit Lighting The lamps inside the vehicle come on when any door is opened. These lamps fade out about 20 seconds after all of the doors have been closed or when the ignition is turned to ON/RUN. They also come on when the unlock symbol button or the horn symbol is pressed on the Remote Keyless Entry (RKE) system transmitter. The lamps inside the vehicle stay on for about 20 seconds after the key is removed from the ignition to provide light as you exit. Battery Load Management The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. Reading Lamps For vehicles with front and rear reading lamps, press the lens to turn the lamp on and off, while the doors are closed. These lamps come on automatically when any door is opened. Parade Dimming Parade dimming is a separate lighting mode that comes on while the parking lamps are turned on during the day. It prevents the display lights and indicator lights from being dim, while the parking lamps are used during the day.
