Headlamp High/Low-Beam Changer; Flash-To-Pass - GMC 2006 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 5-103 and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a 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.
