yellowblue When the thumbwheel is moved to full brilliance, and then into the first detent position, the radio display and PRNDL display will go to the day mode (full intensity). This is known as "parade" mode. The rest of the I/P illumination will stay in the maximum dimming state (full brilliance dimming). Moving the thumbwheel up one more detent will activate the interior dome light circuit (with slightly higher effort). The vehicle is also equipped with a DOME OVERRIDE button. For more information on this feature see "Dome Lamps" in the Index. The delayed entry feature will allow you to enter or exit your vehicle with the lights staying on for about 20 seconds, after the door is closed or ignition is cycled. Turn the knob clockwise to the parking lamp symbol to turn on: Turn the knob clockwise again to the master lighting symbol to turn on all the lamps listed above as well as the headlamps. Turn the knob counterclockwise to OFF to turn off your lamps and lights. Move the thumbwheel next to the switch knob up to adjust instrument panel lights. Move the thumbwheel up to the first notch to return the radio display and gearshift indicator display to full intensity when the headlamps or parking lamps are on. Move the thumbwheel up to the second notch to turn on the interior dome lamps. You can switch your headlamps from high to low beam by pulling on the turn signal/high beam lever. A circuit breaker protects your headlamps. If you have an electrical overload, your headlamps will flicker on and off. Have your headlamp wiring checked right away if this happens.
