Downloaded from www.Manualslib.com manuals search engine 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
inside and outside?
Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil, Other Fluids: Have you checked all levels?
0 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?
Should you delay your trip a short time to avoid a major storm system?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
High way 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.
What can you do about highway hypnosis? First, be aware that it can
happen.

The Certificatioflire
label is found on the
rear edge
of the
driver's door. The
label shows the size
of
your original tires and
the inflation pressures
needed to obtain the
gross weight capacity
of your vehicle.
This is called the GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel, cargo, and tongue
weight, if pulling a trailer.
The CertificatiodTire label also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR).
To find out
the actual loads on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer
can help you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the Gross Axle Weight Rating
(GAWR) for either the front or rear axle.
And, if you do have a heavy load, you should spread it out.
Using heavier suspension components to get added durability might not
change your weight ratings. Ask your dealer
to help you load your vehicle
the right way.

lower.
If the level is lower, add more of the proper mix through the
filler neck until the level reaches the base
of the filler neck.
8. Then replace the pressure cap. At any time during this procedure if
coolant begins to flow out of the filler neck, reinstall the pressure cap.
Be sure the arrows on the pressure cap line
up like this.
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 fully 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 sh
It is merely the cooling system functioning properly. The fan will slow
down when additional cooling is not required and the clutch disengage .ifts.
S.
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.

Downloaded from www.Manualslib.com manuals search engine lnflation - Tire Pressure
The CertificatiodTire label which is on the rear edge of the driver’s door,
shows the correct inflation pressures for your tires, when they’re cold.
“Cold” means your vehicle has been sitting for at least three hours or driven
no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not. If your tires don’t have enough air
(underinflation) you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire pressure. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires
have valve caps, be sure to put them back on. They help prevent
leaks by keeping
out dirt and moisture.
