The control on the driver's side of your instrument panel operates the exterior lamps.

The exterior lamp control has four positions:

(Off): Turn the knob to this position to turn off all exterior lamps including the DRL. This control will spring back to AUTO when released.

AUTO (Automatic): Turn the control to this position to put the system into automatic headlamp mode. AUTO mode, if enabled, will turn the exterior lamps, including your DRL, on and off automatically depending on how much light is available outside the vehicle. Your automatic lights may be disabled even if the control is in the AUTO position.

To enable automatic lighting, do any of the following:

    • Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself.
    • Turn the headlamp control from the parking lamp position to AUTO.
    • Turn the headlamp control from the headlamp position to AUTO.
    • Turn your engine off and then on again with the headlamp control in AUTO.

To disable automatic lighting, do any of the following:

    • Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself.
    • Turn the headlamp control from AUTO to the parking lamp position.
    • Turn the headlamp control from AUTO to the headlamp position.
(Parking Lamps): Turn the control to this position to turn on the parking lamps, together with the following:

    • Sidemarker Lamps
    • Taillamps
    • License Plate Lamps
    • Roof Marker Lamps

&(Headlamps): Turn the control to this position to turn on the headlamps, together with the previously listed lamps and lights. When the vehicle is turned off and the headlamps are in AUTO, the headlamps may automatically remain on for a set time. You can change this delay time using the DIC. See Driver Information Center (DIC) . You can switch your headlamps from low to high-beam by pushing the turn signal/multifunction lever toward the instrument panel.
