(Headlamp High/Low Beam
Changer): Push the lever toward
the instrument panel, to change the
headlamps from low to high beam.
Pull the multifunction lever toward
you and release it, to return to
low-beam headlamps.
When the high beams are on, this
indicator light on the instrument
panel cluster will also be on.

Flash-to-Pass

This feature lets you use the
high-beam headlamps to signal a
driver in front of you that you want
to pass. It works even if the
headlamps are in the automatic
position.
To use it, pull the turn signal lever
toward you, then release it.
If the headlamps are in the
automatic position or on low beam,
your high-beam headlamps turn on.
They will stay on as long as you
hold the lever toward you. The
high-beam indicator on the
instrument panel cluster comes on.
Release the lever to return to
normal operation.
