Instrument Panel Brightness The knob with this symbol is located on the instrument panel to the left of the steering column. Parade Dimming This feature does not let the instrument panel backlight dim during daylight hours while the key is in the ignition and the headlamps are on. Parade dimming automatically works with the light sensor, located on top of the dashboard. If it is dark enough outside and the parking lamps are on, the backlight on the instrument panel can be adjusted by turning the instrument panel brightness knob clockwise or counterclockwise to brighten or dim the lighting. See Instrument Panel Brightness on page 3-20. Turn the knob clockwise or counterclockwise to brighten or dim the lights. Turn the knob completely clockwise to turn on the interior lamps. Reading Lamps The reading lamps are located on the overhead console. These lamps come on automatically when any door is opened. For manual operation, press the button next to each lamp to turn it on or off. If the reading lamps are left on, they automatically shut off 10 minutes after the ignition has been turned off. Entry Lighting The entry lighting system turns on the reading and dome lamps and the backlighting to the exterior lamp control, when a door is opened or if the transmitter unlock button is pressed. If activated by the transmitter, the lighting stays on for about 25 seconds. The entry lighting system uses the light sensor on the instrument panel; so it must be dark outside in order for the lamps to turn on. The lamps turn off about 25 seconds after the last door is closed. They dim then turn off if the ignition key is turned to ON/RUN. They immediately turn off if the power locks are used. 3-20
