2007 CHEVROLET COLORADO turn signal bulb

Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is nished, the lever will
automatically return to the off position.
To signal a lane change, raise or lower the lever
until the arrow starts to ash. Hold it there until
the change is completed. The lever will return by
itself when released.
An arrow on the
instrument panel
cluster will ash in
the direction of the
turn or lane change.As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will
not see your vehicle’s 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
signaling a turn, check for a burned-out bulb or a
blown fuse. For bulb replacement, seeTaillamps,
Turn Signal, Stoplamps and Back-up Lamps
on page 373. For a blown fuse or circuit breaker,
seeFuses and Circuit Breakers on page 433
Turn Signal On Chime
If a turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash of
the turn signal and the message TURN SIGNAL
will also appear in the DIC. To turn the chime and
message off, move the turn signal lever to the
off position.
See “TURN SIGNAL” underDIC Warnings and
Messages on page 202for more information.

Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp
turns while trailering.
When you’re turning with a trailer, make wider turns
than normal. Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring and a heavy-duty turn signal asher.
The arrows on your instrument panel will ash
whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to
turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if
the bulbs on the trailer are burned out.Thus, you may think drivers behind you are seeing
your signal when they are not. It’s important to
check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before
you start down a long or steep downgrade.
If you don’t shift down, you might have to use
your brakes so much that they would get hot
and no longer work well.
When towing at high altitude on steep uphill
grades, consider the following: Engine coolant
will boil at a lower temperature than at normal
altitudes. If you turn your engine off immediately
after towing at high altitude on steep uphill grades,
your vehicle may show signs similar to engine
overheating. To avoid this, let the engine run
while parked (preferably on level ground) with
the automatic transmission in PARK (P) (or
the manual transmission out of gear and the
parking brake applied) for a few minutes before
turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 348.
