2008 Pontiac G5 Owner ManualM

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 5-97.
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.

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 are turning with a trailer, make wider turns
than normal. Do this so your trailer will not 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 may need a
different turn signal asher and/or extra wiring. Check
with your dealer/retailer. 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 gearbeforeyou 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 5-22.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your vehicle may
experience more transmission 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 3-44DIC Warnings and Messages
for more information.
