Downloaded from www.Manualslib.com manuals search engine If you experience one or more of these conditions,
change the
fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools
to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per 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
dangerously low oil level or other problems causing low
oil pressure.
I
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire.
You or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.
1
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

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 inside and outside?
0 Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: 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 wei----er outlook
along your route? Should
you delay your trip a short
time to avoid
a major storm system?
0 Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just
plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with the
same scenery, along
with the hum of the tires on the road,
the
drone of the engine, and the rush of the wind against
the vehicle that can make you sleepy. Don’t
let it happen
to you! If it does, your vehicle can leave the road in
less
than a second, and you could crash and be injured.

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 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 Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If
you need to use a solvent:
1.
2.
3.
4.
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper.
Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at
the
outside of the stain, “feathering” toward the center.
Keep changing to a clean section of the cloth.
When
you clean a stain from fabric, immediately
dry the area with a blow dryer to help prevent a
cleaning ring.
Fabric Protection
Your vehicle has upholstery and carpet that has been
treated with Scotchgard“ Fabric Protector, a
3M
product. It protects fabrics by repelling oil and water,
which are the carriers
of most stains. Even with this
protection,
you still need to clean your upholstery and
carpet often to keep
it looking new. Further information
on cleaning
is available by calling
1-800-433-3296 (in Minnesota, 1-800-642-6167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left
on a vehicle’s seat fabric. They should be removed as
soon as possible.
Be careful, because the cleaner will
dissolve them and may cause them to spread.

Downloaded from www.Manualslib.com manuals search engine Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it
clean by washing it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays of the
sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
Don’t
use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed
to dry on
the surface, or they could stain. Dry the finish with a
soft, clean chamois or an all-cotton towel
to avoid
surface scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
Cleaning Exterior LampsLenses
Use lukewarm or cold water, a soft cloth and a liquid
hand, dish or car washing (mild detergent) soap to clean
exterior lamps and lenses. Follow instructions under
“Washing Your Vehicle.”
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary
to remove residue from the paint
finish.
You can get GM-approved cleaning products
from your dealer. (See “Appearance Care and Materials’’
in
the Index.) Your
vehicle has a “basecoat/clearcoat” paint finish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoatklearcoat
paint finish.
I NOTICE:
Machine compounding or aggressive polishing on
a basecoatklearcoat paint finish may dull the
finish or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage
your vehicle’s finish if they remain on painted
surfaces. Wash the vehicle as soon as possible. If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces
to remove foreign matter.
Exterior painted surfaces are subject
to aging, weather
and chemical fallout that can take their toll over a period
of years. You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
