This feature lets you use your high-beam headlamps to signal the driver in front of you that you want to pass. It works even if the headlamps are off. Pull the turn signal lever toward you a little, but not so much that you hear a click.

If the headlamps are off or on low-beam, the high-beam headlamps will turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster will come on. Release the lever to return it to the normal operation.
