If the Twilight Sentinel@lighting is active, it can be disabled by turning on the manual parking lamps. This lighting will be disabled until the key is turned from ON or until the manual parking lamps are turned off. Also, it's possible that your headlamps may go out if you drive from a dark area into a bright area like a lighted parking lot. If this happens, turn on your headlamps with the exterior lamp control. Interior Lamps Instrument Panel Brightness When it is dark outside, you can brighten or dim your instrument panel cluster lights using the DIM knob, located to the left of the steering wheelon the instrument panel. Turn the knob clockwise to brighten the instrument panel cluster lights and displays. Turn the knob clockwise all the way to turn on the interior courtesy lamps. Turn the knob counterclockwise to dim the instrument panel cluster lights and displays and to turn off the courtesy lamps. Exterior Lighting Battery Saver If the exterior lamp control has been left on, the exterior lamps will turn off approximately 10 minutes after the ignition is turned to OFF and a door has been opened. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps 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 turning the ignition to OFF and opening a door. To delay the lamps from turning off, see "Twilight Sentinel@,"listed previously. Courtesy Lamps If it is dark enough outside, when any door is opened, several lamps will come on. They make it easier for you to enter and leave the vehicle. Turn the dimmer knob all the way clockwise to turn the interior courtesy lamps on. 3-1 6
