Downloaded from www.Manualslib.com manuals search engine Off-Road Driving with Your Four-wheel Drive Vehicle
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.
Adjust your inside rearview mirror to reduce the glare from headlights
behind you.

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.
Trailer Light Wiring
See “Trailer Wiring Harness” in the Index.
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
transmission may be damaged.
Use the regular brakes, set the parking brake or block the wheels to keep
your vehicle from rolling.

your vehicle than this manual can.
To order the proper service manual, see
“Service Publications” in the Index.
You should keep a record with all parts receipts and list the mileage and the
date of
any service work you perform. See “Maintenance Record” in the

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt can easily get into your engine, which will damage
it. Always have the air cleaner in place when you’re driving.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine
oil is changed. Refer to the Maintenance Schedule to determine
when
to change your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may choose to have this
done at a
GM dealership Service Department.
If
you do it yourself, be sure to follow all the instructions here, or you could
get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your transmission. Too
much can mean that some of the fluid could come out and fall on
hot engine parts or exhaust system, starting
a fire. Be sure to get
an accurate reading if you check your transmission fluid.
