Headlamp High/Low-Beam Changer; Flash-To-Pass - GMC Envoy Owner's Manual

If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check the fuse. See Fuses and Circuit Breakers
on page 5-97 and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal flasher is
used. With this flasher installed, the signal indicator will
flash even if a turn signal bulb is burned out. Check
the front and rear turn signal lamps regularly to make
sure they are working.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.

Headlamp High/Low-Beam Changer

To change the headlamps from low to high beam,
push the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever
toward you. Then release it.

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'll
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.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
