Standard Cluster Digital Cluster
f
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.
On the digital cluster, a box around the oil pressure symbol
will begin to
flash when the oil pressure is low.

Your vehicle may have either a 5-wire or 7-wire harness.
The light duty trailer wiring is a 5-wire harness assembly taped and bundled
at the left corner
of the vehicle interior, next to the endgate. The harness has
no connector, and you should have a qualified service person wire your
harness for
you. It must be routed out of your vehicle and attached so that
the trailer or the body won’t pull
it.
The heavy duty trailer wiring is a 7-wire harness assembly consisting of a
5-wire harness and a 2-wire harness taped together and stored under the
vehicle, along
the rear frame crossmember. It has a 30-amp feed wire with
an inline fuse located by the junction block. See “Fuses and Circuit
Breakers” in the Index.
Both the 5-wire harness and the 2-wire harness have no connector and
should be wired by a qualified service person. Attach the harness to the
trailer, then tape or strap
it to your vehicle’s frame rail. Be sure you leave it
loose enough so the wiring doesn’t bend or break, but not so loose that it
drags
on the ground.
Store the harness in its original place.
Wrap the harness together and tie it
neatly so it won’t be damaged.

A tape player that is not cleaned regularly can cause reduced sound quality,
ruined cassettes, or a damaged mechanism. Cassette tapes should be stored
in their cases away from contaminants, direct sunlight, and extreme heat.
If
they aren’t, they may not operate properly or cause failure of the tape
player.
Your tape player should be cleaned regularly each month
or after every 15
hours of use. If you notice a reduction in sound quality, try a known good
cassette to see if the tape or the player is at fault.
If this other cassette has no
improvement in sound quality, clean the tape player.
Clean your tape player with a wiping-action, non-abrasive cleaning
cassette, and follow the directions provided with it.
Cassettes
are subject to wear and the sound quality may degrade over time.
Always make sure that the cassette tape is in good condition before you
have your tape player serviced.

This off-road guide is for vehicles that have four-wheel drive.
Also, see “Anti-lock Brakes”
in the Index.
If your vehicle doesn’t have four-wheel drive,
you shouldn’t drive off-road
unless you’re on a level, solid surface.
Off-road driving can be great
fun. But it does have some definite hazards.
The greatest
of these is the terrain itself.
“Off-roading” means you’ve left the great North American road system
behind. Traffic lanes aren’t marked. Curves aren’t banked. There are no
road signs. Surfaces can be slippery, rough, uphill or downhill. In short,
you’ve gone right back to nature.
Off-road driving involves some new skills. And that’s
why it’s very
important that you read this guide. You’ll find many driving tips and
suggestions. These
will help make your off-road driving safer and more
enjoyable.
Before You Go Off-Roading
There are some things to do before you go out. For example, be sure to have
all necessary maintenance and service work done. Be sure you read all the
information about your four-wheel drive vehicle
in this manual. Is there
enough fuel? Is the spare tire
fully inflated? Are the fluid levels up where
they should be? What are the local
laws that apply to off-roading where
you’ll be driving? If you don’t know, you should check with law
enforcement people
in the area. Will you be on someone’s private land? If
so, be sure to get the necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about how to load your
vehicle.
The heaviest things should be on the load floor and forward of your
rear axle. Put heavier items as far forward as you can.
Be sure the load is secured properly, so driving on the off-road terrain
doesn’t toss things around.

Downloaded from www.Manualslib.com manuals search engine 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.
Here are some tips
on night driving.
Drive defensively.
Don’t drink and drive.

Downloaded from www.Manualslib.com manuals search engine 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
inside and outside?
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?
Maps: Do you have up-to-date maps?
Should
you delay your trip
a short time to avoid a major storm system?

Downloaded from www.Manualslib.com manuals search engine 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.
Then here are some tips:
Make sure your vehicle is well ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road ahead and to the sides. Check
your mirrors and your instruments frequently.
If you get sleepy, pull off the road into a rest, service, or parking area
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.)

Downloaded from www.Manualslib.com manuals search engine 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.

Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
! NOTICE:
~ When operating a power winch on your vehicle always leave the \
l transmission in the neutral position. Do not leave an automatic
transmission in
P (Park) or a manual transmission in gear or the
