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

No one can see as well at night as in the daytime. But as we get older these
differences increase. A 50-year-old driver may require at least twice as
much light to see the same thing at night as a 20-year-old.
What
you do in the daytime can also affect your night vision. For example,
if you spend the day in bright sunshine you are wise
to wear sunglasses.
Your eyes will have less trouble adjusting
to night. But if you’re driving,
don’t wear sunglasses at night. They may cut down on glare from
headlights, but they also make a
lot of things invisible.
You can be temporarily blinded by approaching lights. It can take a second
or two,
or even several seconds, for your eyes to readjust to the dark. When
you are faced with severe glare
(as from a driver who doesn’t lower the high
beams,
or a vehicle with misaimed headlights), slow down a little. Avoid
staring directly into the approaching lights.
Keep your windshield and all the glass
on your vehicle clean - inside and
out. Glare at night is made much worse by dirt on the glass. Even the inside
of the glass can build up a film caused by dust. Dirty glass makes lights
dazzle and flash more than
clean glass would, making the pupils of your
eyes contract repeatedly.
Remember that your headlights light up far less
of a roadway when you are
in a turn or curve. Keep your eyes moving; that way, it’s easier to pick out
dimly lighted objects. Just as your headlights should be checked regularly
for proper aim,
so should your eyes be examined regularly. Some drivers
suffer from night blindness
- the inability to see in dim light - and aren’t
even aware of it.
Driving in the Rain
Rain and wet roads can mean driving trouble. On a wet road you can’t stop,
accelerate or turn as well because your tire-to-road traction isn’t as good as
on dry roads. And, if your tires don’t have much tread left, you’ll get even

save time and energy. (See the
next section, “Freeway Driving.”)
0 Treat a green light as a warning signal. A traffic light is there because
the corner
is busy enough to need it. When a light turns green, and just
before
you start to move, check both ways for vehicles that have not
cleared the intersection or may be running the red light.
Freeway Driving
-.
Mile for mile, freeways (also called thruways, parkways, expressways,
turnpikes, or superhighways) are the safest of all roads. But they have their
own special rules.
The most important advice on freeway driving is: Keep up with traffic and
keep to the right. Drive at the same speed most of
the other drivers are
driving. Too-fast or too-slow driving breaks
a smooth traffic flow. Treat the
left lane
on a freeway as a passing lane.
At the entrance there is usually a ramp that leads to the freeway.
If you have
a clear view of the freeway as
you drive along the entrance ramp, you
should begin to check traffic. Try
to determine where you expect to blend
with the flow. Try to merge into
the gap at close to the prevailing speed.
Switch
on your turn signal, check your mirrors and glance over your
shoulder as often as necessary. Try
to blend smoothly with the traffic flow.
Once you are
on the freeway, adjust your speed to the posted limit or to the
prevailing rate if it’s slower. Stay in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use your turn signal.
Just before
you leave the lane, glance quickly over your shoulder to make
sure there isn’t another vehicle
in your “blind” spot.

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 Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg) loaded, then it needs
its own brakes
- and they must be adequate. Be sure to read and follow the
instructions for the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Your trailer brakes system can tap into vehicle’s hydraulic brake system
except:
Don’t tap into your vehicle’s brake system
if the trailer’s brake system will
use more than 0.02 cubic inch (0.3~~) of fluid from your vehicle’s master
cylinder.
If it does, both braking systems won’t work well. You could even
lose your brakes.
Will the trailer parts take
3,000 psi (20 650 kPa) of pressure? If not, the
trailer brake system must not be used with your vehicle.
If everything checks out this far, then make the brake fluid tap at the
port on
the master cylinder that sends fluid
to the rear brakes. But don’t use copper
tubing for this. If
you do, it will bend and finally break off. Use steel brake
tubing.
Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting out
for the open road, you’ll want
to get to know your rig. Acquaint yourself
with the feel of handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle
you are driving is now a good
deal longer and not nearly
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the brakes are working. This lets
you check your electrical connection at the same time.

Downloaded from www.Manualslib.com manuals search engine During your trip, check occasionally to be sure that the load is secure, and
that
the lights and any trailer brakes are still working.
Following Disfance
Stay at least twice as far behind the vehicle ahead as you would when
driving your vehicle without a trailer. This can help you avoid situations that
require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need
to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left.
To move the trailer to the
right, move your hand to the right. Always
back up slowly and, if possible,
have someone guide you.

Downloaded from www.Manualslib.com manuals search engine Making Turns
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other
objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows
on your instrument panel will
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash
for turns
even if the bulbs on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when
they are not. It’s important
to check occasionally to be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or
steep downgrade. If you don’t
shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed
to around 45 mph
(70 kdh) to reduce the possibility of engine and transmission overheating.
If you have an automatic transmission,
you should use “D” when towing a
trailer. Operating your vehicle in “D” when towing a trailer will minimize
heat buildup and extend the
life of your transmission. Or, if you have a
manual transmission with
fifth gear, it’s better not to use fifth gear, just
drive in fourth gear (or, as
you need to, a lower gear).
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet, or into
gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb
the load.

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.
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.

Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles
aren’t touching each other. If they are, it could cause
ground connection you don’t want. You wouldn’t be able to start you1
vehicle, and the bad grounding could damage the electrical systems.
You could be injured if the vehicles roll. Set
the parking brake firmly
on each vehicle. Put an automatic transmission in “P’ (Park) or a
a
manual transmission in “N” (Neutral). If you have a four-wheel-drive
vehicle with
a manual transfer case shift lever, be sure the transfer case
is not in “N” (Neutral).
Turn
off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!
