Turn And Lane-Change Signals - GMC 2007 Envoy Denali Owner's Manual

Turn and Lane-Change Signals

The turn signal has two upward (for right) and
two downward (for left) positions. These positions
let you signal 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 signal a lane change, raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever returns
by itself when released. The bottom of the outside
rearview mirrors might also have lane change
indicators.

An arrow on the
instrument panel cluster
flashes in the direction
of the turn or lane
change.
As you signal a turn or a lane change, if the
arrows flash more quickly than normal, a signal
bulb could 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 the fuse. See Fuses and
Circuit Breakers on page 493 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 flashes 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 sounds at each flash of
the turn signal. To turn off the chime, move
the turn signal lever to the off position.
