For 1990-2009 cars only

This feature lets you use the high-beam headlamps to signal the driver in front of you that you want to pass.

The flash-to-pass feature will only work with the headlamps on. It does not work with Daytime Running Lamps (DRL).

Pull and hold the turn signal lever toward you to use.

If the headlamps are on low beam, pulling the turn signal towards you will flash the high beams.
