Turn And Lane-Change Signals; Headlamp High/Low-Beam Changer - GMC 2008 Sierra 1500 Pickup Owner's Manual

Turn and Lane-Change Signals

The turn signal has two upward (for right) and
two downward (for left) positions. Each position
signals a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever returns automatically
to the starting position.
To signal a lane change, raise or lower the lever until
the arrow starts to flash. Hold it there until your
lane change is completed. The lever returns to the
starting position by itself when it is released.
If the arrows flash more quickly than normal as you
signal a turn or a lane change, a signal bulb might be
burned out and other drivers will not see the turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not come on when you signal
a turn, check for burned-out bulbs and a blown fuse.
See Fuses and Circuit Breakers on page 5-108.
3-8
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime sounds at each flash of the turn signal
and the message TURN SIGNAL ON also appears in
the Driver Information Center (DIC). Move the turn
signal lever to the off position, to turn the chime and
message off.
