Flash-To-Pass Feature; Headlamp High/Low-Beam Changer - GMC 2003 Sonoma Owner's Manual

To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
don't flash but just stay on, a signal bulb may be burned
out and other drivers won't see your turn signal.
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 5-93 ) and for burned-out bulbs.
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 or high
to low beam, pull the multifunction lever all the way
toward you until you hear a click. Then release it.

Flash-To-Pass Feature

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, but not
so far that you hear a click.
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
and the high-beam indicator on the dash will come
on. Release the lever to return to normal operation.
When the high-beam
headlamps are on, this
indicator light on the
instrument panel cluster
will also be on.
