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.

DO NOT USE SAE 2OW-50 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your vehicle. However, you
can use SAE 1 OW-30 if it's going to be 0°F (-1 SOC) or above. These
numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 2OW-50.

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:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 1 28 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean wafer (preferably distilled) and one-half
antifreeze that meets
“GM Specification 6038-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to “GM
Specification 6038-M. 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.

Section
This section covers the maintenance required for your vehicle. Your vehicle
needs these services to retain its safety, dependability and emission control
performance.
Protection I
Have you purchased the GM Protection Plan? The Plan supplements your
new vehicle warranties. See your GM dealer for details.
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your vehicle in good
working condition, but also helps the environment.
All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal of important components can significantly affect the quality of the
air we breathe. Improper fluid levels or even the wrong tire inflation can
increase the level
of emissions from your vehicle. To help protect our
environment, and
to help keep your vehicle in good condition, please
maintain your vehicle properly.
