Flash-to-Pass

This feature lets you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your 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 to normal operation.
