Downloaded from www.Manualslib.com manuals search engine Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front and
rear turn signal
lamps will flash on and off. The
hazard warning
flasher button is located on top of
the steering column.
Press the button down to make your front and rear turn
signal lamps flash
on and off. Your hazard warning
flashers work no matter what position your
key is in,
and even if the key isn’t in.
To turn off the flashers, press the button down again.
When the hazard warning flashers are
on, your turn
signals won’t work. They also won’t flash while
you’re braking.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before
it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle.
When your vehicle is being towed, have the ignition
key in the
OFF position. The steering wheel should
be clamped in a straight-ahead position, with a
clamping device designed for towing service. Do not
use the vehicle’s steering column lock for this. The
transmission should be in NEUTRAL
(N) and the
parking brake released.
I I
If your vehicle has the all-wheel-drive option, it can
only be towed with all four wheels
off the ground.
A dolly must be used under the unraised wheels
when towing or the vehicle must be transported on a
flat bed carrier.
Don’t have your vehicle towed with the wheels in
contact with the ground
if it has all-wheel drive. If
a vehicle with all-wheel drive must be towed with
sling-type or wheel-lift equipment, then either the
front or rear wheels must be supported on a dolly.
NOTICE:
If your vehicle has all-wheel drive, do not have
it towed with the wheels in contact with the
ground or vehicle damage may occur.
A dolly
must be used under the unraised wheels when
towing or the vehicle must be transported
on a
flat bed carrier.

Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise
This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air to cool the engine. In most everyday driving
conditions, the clutch is not
fully engaged. This
improves fuel economy and reduces fan noise. Under
heavy vehicle loading, trailer towing andor high
outside temperatures, the fan speed increases when the
clutch engages.
So you may hear an increase in fan
noise. This is normal and should not be mistaken
as the
transmission slipping or making extra shifts. It is merely
the cooling system functioning properly. The fan will
slow down when additional cooling
is not required and
the clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away
as the fan clutch disengages.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain your tires properly. If air goes
out of
a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the
accelerator pedal and grip the steering wheel firmly.
Steer
to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to
a stop -- well off the road if possible.
If
a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.

Downloaded from www.Manualslib.com manuals search engine If You’re Stuck: In Sand, Mud,
Ice
or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known
as
“rocking” can help you get out when you’re stuck, but
you must use caution.
L
A CAUTION: I I
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transmission or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little
as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires.
If you spin the wheels
too fast while shifting your transmission back
and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. Then shift back
and forth between
REVERSE (R) and a forward gear,
spinning the wheels as little as possible. Release the
accelerator pedal while you shift, and press lightly on
the accelerator pedal when the transmission is in gear. If
that doesn’t get you out after a few tries, you may need
to be towed out. If you do need to be towed out, see
“Towing Your Vehicle” in the Index.

When you replace your radiator pressure cap, a GM cap
is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.

Downloaded from www.Manualslib.com manuals search engine How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top
of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten
it. Then remove the cap again and
look at
the fluid level on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up
to the mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in
the Index.
Always
use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
I Open the cap labeled
WASHER FLUID ONLY.
Add washer fluid until the
tank is full,
