Headlamp High/Low-Beam Changer - GMC Sierra Classic 2007 Owner's Manual

As you signal a turn or a lane change, if the
arrows flash more quickly than normal, a signal
bulb may be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and a
blown fuse. See Fuses and Circuit Breakers on
page 596.
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 and the message TURN SIGNAL
ON will also appear in the Driver Information
Control (DIC). To turn the chime and message off,
move the turn signal lever to the off position.
An arrow on the
instrument panel cluster
will flash in the
direction of the turn or
lane change.
