For 1990-2009 cars only

This feature allows the high-beam headlamps to be used to signal the driver in front of you that you want to pass.

Pull and hold the turn signal/multifunction lever toward you to use this feature. When this is done the following will occur:

    • If the headlamps are off, in low-beam or in Daytime Running Lamps (DRL) mode, the high-beam headlamps will turn on. They will stay on as long as the lever is held there. Release the lever to turn them off.
    • For vehicles with High Intensity Discharge (HID) headlamps, the low-beam headlamps must be on to activate the high-beam headlamps. See High Intensity Discharge (HID) Lighting .
    • If the headlamps are already in high-beam mode, they will remain on high-beam.
