Cornering Lamps The cornering lamps come on when the headlamps or parking lamps are on and you signal a turn with the multifunction lever. They provide more light for cornering. Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel and footwell lights, if equipped. The button for this control is located below the exterior lamps control. Push the button in and release to extend the button. Turn the button clockwise or counterclockwise to brighten or dim the lights. Exterior Lighting Battery Saver If the exterior lamp button has been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned to LOCK/OFF and a door has been opened. This protects against draining the battery if the headlamps or parking lamps are accidentally left on. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on after the ignition is turned to LOCK/OFF and any door is opened. Courtesy Lamps The courtesy lamps are located on the headliner above the rear seat. These lamps come on by turning the instrument panel brightness knob fully clockwise or when any door is opened and it is dark outside. Puddle lamps are located on the bottom of the front and rear door trim. Professional vehicles have an additional dome lamp and also opera lamps. 3-35
