2007 CHEVROLET COBALT 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
return automatically.
An arrow on the
instrument panel
cluster will ash in the
direction of the turn
or lane change.
To signal a lane change, raise or lower the lever
until the arrow starts to ash. 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
ash rapidly, 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 the fuse. SeeFuses and Circuit
Breakers on page 384.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam, push the turn signal lever away from you.
When the high beams
are on, this light on
the instrument panel
cluster will also be on.
To change the headlamps from high beam to low
beam, pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam
headlamps to signal a driver in front of you
that you want to pass.
To use it, pull the turn signal/multifunction lever
toward you until the high-beam headlamps
come on, then release the lever to turn them off.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring.
Check with your dealer. 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 are 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 is important to check
occasionally to be sure the trailer bulbs are
still working.
Driving on Grades
Notice:Do not tow on steep continuous
grades exceeding 6 miles (9.6 km). Extended,
higher than normal engine and transmission
temperatures may result and damage your
vehicle. Frequent stops are very important to
allow the engine and transmission to cool.Reduce speed and shift to a lower gearbefore
you start down a long or steep downgrade. If you
do not shift down, you might have to use your
brakes so much that they would get hot and
no longer work well.
Pay attention to the engine coolant gage. If the
indicator is in the red area, turn off the air
conditioning to reduce engine load. SeeEngine
Overheating on page 309.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your
vehicle may experience more transaxle shifting.
A COOLING MODE ON message may also appear
in the DIC. This alerts the driver that the shifting
mode is in progress and is aiding engine cooling.
SeeDIC Warnings and Messages on page 184
for more information.
