Fog Lamps The fog lamps button is on the exterior lamps control to the left of the steering column. 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 the lamps need to be left 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. # (Fog Lamps): Press to turn the fog lamps on or off. A light comes on in the instrument panel cluster when the fog lamps are in use. See Instrument Panel Cluster on page 4 ‑ 28 . The ignition must be in the ON/RUN position for the fog lamps to work. The fog lamps will go off when the headlamps are changed to high-beam. Some localities have laws that require the headlamps to be on along with the fog lamps. Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The knob for this control is located next to the exterior lamps control. Push the knob in and release when it pops out. Turn the knob clockwise to increase the brightness of the instrument panel lights and counter clockwise to decrease the brightness. Turning the knob completely clockwise to the detent will turn on the courtesy lamps. Cornering Lamps For vehicles with this feature, the cornering lamps come on when: the headlamps or parking lamps are on, the vehicle is not in P (Park), and you signal a turn with the turn signal/multifunction lever. They provide more light for cornering. 4-12
