To save fuel, run the engine for only
short periods as needed to warm the
vehicle and then shut the engine off
and close the window most of the
way to save heat. Repeat this until
help arrives but only when you feel
really uncomfortable from the cold.
Moving about to keep warm also
helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help with
the headlamps. Do this as little as
possible to save fuel.If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
{CAUTION
If you let your vehicle’s tires spin at
high speed, they can explode, and
you or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going above
55 km/h (35 mph) as shown on the
speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 9-61 .
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth between
R (Reverse) and a forward gear,
or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on
the accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing the Vehicle on page 9-73 .

2. Raise the wiper arm until itcomes off.
You will hear a clicking sound
when the arm comes off. 3. Push the rear wiper assembly
straight into the rear wiper arm.
4. Reengage the two pins to the rear wiper arm by pushing
them down.
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit until
the until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by electrical
problems. Fuses and circuit breakers protect
the following in the vehicle:
•Headlamp Wiring
•Windshield Wiper Motor
•Power Windows and other Power
Accessories
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have
the headlamp wiring checked right
away if the lamps go on and off or
remain off.

Wheel Alignment and
Tire Balance
The tires and wheels on the vehicle
were aligned and balanced carefully
at the factory to give the longest tire
life and best overall performance.
Adjustments to wheel alignment and
tire balancing will not be necessary
on a regular basis. However, if there
is unusual tire wear or the vehicle
pulls to one side or the other, the
alignment should be checked. If the
vehicle vibrates when driving on a
smooth road, the tires and wheels
might need to be rebalanced.
See your dealer/retailer for proper
diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have
the same load-carrying capacity,
diameter, width, offset and be
mounted the same way as the
one it replaces.
If you need to replace any of the
wheels, wheel bolts or wheel nuts,
replace them only with new GM
original equipment parts. This way,
you will be sure to have the right
wheel, wheel bolts and wheel nuts
for the vehicle.{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling of your
vehicle, make your tires lose
air and make you lose control.
You could have a collision in
which you or others could be
injured. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice: The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
See If a Tire Goes Flat on page 9-62
for more information.
