Downloaded from www.Manualslib.com manuals search engine How long should you keep the coolant heater plugged in? The answer
depends on the weather, the kind
of oil you have, and some other things.
Instead of trying to list everything here, we ask that you contact a
GM
dealer in the area where you’ll be parking your vehicle. The dealer can give
you the best advice for
that particular area.
Automatic Transmission
There are several
different positions for
your shift lever.
P (Park) - This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

Downloaded from www.Manualslib.com manuals search engine Here are things some owners ask about. None of these indicate a problem
with your fuel gage:
0 At the gas station, the gas pump shuts off before the gage r\
eads full.
The fuel tank will take either a little more or a little less fuel to fill up
than the gage shows.
The gage moves a little when you turn a corner or speed up.
The gage doesn’t go back to empty when you turn off the ignition.
For your fuel tank capacity, see the Index under “Fluid Capacities.”
Oil Pressure Gage
Standard Cluster Digital Cluster
The oil pressure gage shows the engine oil pressure in psi (pounds pe\
r
square inch) when the engine is running. Canadian vehicles indicate
pressure in
kPa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and oil viscosity, but readings above the low pressure
zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerous\
ly low oil
level or other problems causing low oil pressure.
On the digital cluster, a box around the oil pressure symbol \
will begin to
flash when the oil pressure
is low.

Damage to your engine from neglected oil problems can be
costly and
is not covered by your warranty.
Engine Coolant Temperature Gage
Standard Cluster
If you have the Standard Cluster, you have a gage that shows the engine
coolant temperature.
If the gage pointer moves to the “H” (red) side, your
engine
is too hot!
It means that your engine coolant has overheated. If you have been
operating your vehicle under normal driving conditions, you shou\
ld pull
off
the road, stop your vehicle and turn off the engine as soon as possible.
If you have a digital cluster, a box around the temperature symbol will also
flash when your engine is too hot.

Handle discs carefully. Store them in their original cases or other protective
cases and away from direct sunlight and dust. If the surface of a disc is
soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling discs. Pick up discs
by grasping the outer edges or the edge of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes without being
damaged. If the mast should ever become slightly bent, you can straighten it
out by hand. If the mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in
a while to be sure the mast is still tightened to the
fender.

Downloaded from www.Manualslib.com manuals search engine Just before you leave the lane, glance quickly over your shoulder to make
sure there isn’t another vehicle in your “blind” spot.
Once you are moving on
the freeway, make certain you allow a reasonable
following distance. Expect to move slightly slower
at night.
When you want
to leave the freeway, move to the proper lane well in
advance. If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you must start when you’re
not fresh
- such as after a day’s work - don’t plan to make too many
miles that first part of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep
it serviced and maintained,
it’s ready to go. If
it needs service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
GM dealerships all across
North America. They’ll be ready and willing to help
if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are all windows clean

Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe, trouble-free trip. Is the tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook along your route?
Should you delay your trip a short time to avoid a major storm system?
Maps: Do you have up-to-date maps?

You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured.
and both your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and shift to
5. Release the regular brakes.
“P” (Park).
When You Are Ready to Leave After Parking on a 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. Thin.gs 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.
Trailer Light Wiring
See “Trailer Wiring Harness” in the Index.

Downloaded from www.Manualslib.com manuals search engine When you decide it’s 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 or above FULL. 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.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed
is doubled by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn
off the engine.

If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard
to find. Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or
at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode,
and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us where
you’re going and give your Vehicle Identification Number (VIN).
