the air will flow through (instrument panel, defroster, heater, etc.).
OFF - This setting turns off all heating functions. Some outside air will
still come out of the heater outlet whenever the vehicle is moving forward.
VENT - Airflow is through the instrument panel vents. Set the upper knob
to the temperature desired. This setting is useful for mild outside
temperatures, when little heating or cooling is desired.
BI-LEV - Outside air comes in through the heater floor vents and the
instrument panel vents. This setting is useful
in cool weather with bright
sunlight.
HEAT
- Heated air comes out through the heater floor vents and
windshield defroster vents. This setting is useful for cold weather.
BLEND - Airflow is divided equally between the heater floor vent and the
windshield defroster vents. This setting is useful
in cool weather when you
have fog
or ice on the windshield or side windows.
DEF - This setting directs most air through the windshield defroster vents
and some through the heater vents. This setting
is useful when you have fog
or ice on the windshield.
Heater/Air Conditioning Controls
If your vehicle has air
conditioning, your

Downloaded from www.Manualslib.com manuals search engine Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your
passengers
could drown. If it’s only inches deep, it can still wash
away the ground from under your tires, and you could lose
traction and roll the vehicle over. Ron’t drive through rush\
ing water.
After Off-Road Driving
Remove any brush or debris that has collected on the underbody, chassis or
under the hood. These accumulations can be a fire hazard.
After operation in mud
or sand, have the brake linings cleaned and checked.
These substances can cause glazing and uneven braking. Check the body
structure, steering, suspension, wheels, tires, and exhaust system for
damage. Also, check the fuel lines and cooling system for any leakage.
Your vehicle will require more frequent service due to off-road
use. Refer
to the Maintenance Schedule for additional information.
Driving at Night
Night driving is more dangerous than day driving. One reason is that some
drivers
are likely to be impaired - by alcohol or drugs, with night vision
problems, or by fatigue.

Make sure your vehicle is well ventilated, with a comfortably cool
interior.
0 Keep your eyes moving. Scan the road ahead and to the sides. Check
If you get sleepy, pull off the road into a rest, service, or parking area
your
mirrors and your instruments frequently.
and take
a nap, get some exercise, or both. For safety, treat drowsiness
on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from driving in flat or
rolling terrain.
If you drive regularly in steep country, or if you’re planning
to visit there,
here are some tips that can make your trips safer and more enjoyable. (See
“Off-Road Driving” in the Index for information about driving off-road.)
0 Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transmission. These parts can work
hard on mountain roads.
0 Know how to go down hills. -The most important thing to know is this:
let your engine do some
of the slowing down. Shift to a lower gear
when you
go down a steep or long hill.

1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. Each of these is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a
good idea to review these
sections before you start your trip.
Check periodically to
see that all hitch nuts and bolts are tight.

safe to lift the hood,
here's what you'll see:
A. Coolant recovery
tank
B. Radiator pressure
cap
C. Engine fan
If the coolant inside the coolant recovery tank is boiling, don't do anything
else until it cools down.
The coolant level should be at the
ADD mark. If it isn't, you may have a
leak in the radiator
hoses, heater hoses, radiator, water pump or somewhere
else in the cooling system.

Downloaded from www.Manualslib.com manuals search engine When the coolant in the coolant recovery tank is at ADD, start your vehicle.
If the overheat warning continues, there's one more thing you can try. You
can add the proper coolant mix directly to the radiator, but be sure the
cooling system is cool before you do it.

1 . You can remove the radiator pressure cap when the cooling system,
including the radiator pressure cap and upper radiator hose,
is no longer
hot. Turn the pressure cap slowly to the left until it first stops. (Don’t
press down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means there is still some
pressure left.

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 every day
driving conditions the clutch is not engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading, trailer towing and/or
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, 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 What to Use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants” in the Index.
Engine Coolant
The following explains your cooling system and how to add coolant when it
is low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your vehicle will:
Give freezing protection down to -34°F (-37 “C).
Give boiling protection up to 262°F (128 “C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 6038-M,” or “GM Specification
6043-M’ with the 2.2L (LN2) Code 4 engine, which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 603%”’ or “GM Specification 6043-M” with the 2.2L
(LN2) Code 4 engine. Use GM Coolant Supplement (Sealer) with a
complete coolant flush and refill. If you use this mixture, you don’t need to
add anything else.
