Downloaded from www.Manualslib.com manuals search engine Stalling on an lncline
If your vehicle stalls when you’re crossing an incline, be sure you (and your
passengers) get
out on the uphill side, even if the door there is harder to
open. If
you get out on the downhill side and the vehicle starts to roll over,
you’ll be right in its path.
If
you have to walk down the slope, stay out of the path the vehicle will take
if it does roll over.
Driving In Mud, Sand, Snow, Or lce
When you drive in mud, snow or sand, your wheels won’t get good traction.
You can’t accelerate as quickly, turning is more difficult, and you’ll need
longer braking distances.
It’s best
to use a low gear when you’re in mud - the deeper the mud, the
lower
the gear. In really deep mud, the idea is to keep your vehicle moving
so you don’t get stuck.
When
you drive on sand, you’ll sense a change in wheel traction. But it will
depend upon how loosely packed
the sand is. On loosely packed sand (as on
beaches or sand dunes) your tires will tend to sink into the sand. This has an
effect
on steering, accelerating, and braking. You may want to reduce the air
pressure in your tires slightly when driving on sand. This
will improve
traction.

Downloaded from www.Manualslib.com manuals search engine Hard packed snow and ice offer the worst tire traction. On these surfaces,
it’s very easy
to lose control. On wet ice, for example, the traction is so poor
that you will have difficulty accelerating. And if you do get moving, poor
steering and difficult braking can cause you to slide out of control.
Driving In Water
Light rain causes no special off-road driving problems. But heavy rain can
mean flash flooding, and flood waters demand extreme caution.
Find out how deep the water is before you drive through it. If it’s deep
enough to cover your wheel hubs, axles, or exhaust pipe, don’t try it
- you
probably won’t get through. Also, water that deep can damage your axle and
other vehicle parts.
If the water isn’t too deep, then drive through it slowly. At fast speeds, water
splashes on your ignition system and your vehicle can stall. Stalling can also
occur if you get your tailpipe under water. And, as long as your tailpipe is
under water, you’ll never be able to start your engine. When you go through
water, remember that when your brakes get wet, it may take you longer to
stop.

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 Night Vision
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

Downloaded from www.Manualslib.com manuals search engine Hydroplaning doesn’t happen often. But it can if your tires haven’t much
tread or
if the pressure in one or more is low. It can happen if a lot of water
is standing on the road.
If you can see reflections from trees, telephone
poles, or other vehicles, and raindrops “dimple” the water’s
surface, there
could be hydroplaning.
Hydroplaning usually happens at higher speeds. There just isn’t a hard and
fast rule about hydroplaning. The best advice is to slow down when it
is
raining.
Some Other Rainy Weather Tips
Turn on your low-beam headlights - not just your parking lights - to
help make you more visible to others.
Besides slowing down, allow some extra following distance. And be
especially careful when you pass another vehicle. Allow yourself more
clear room ahead, and be prepared
to have your view restricted by road
spray.
Have good tires with proper tread depth. (See “Tires” in the Index.)
City Driving
x
One of the biggest problems with city streets is the amount of traffic on
them. You’ll want to watch out for what the other drivers are doing and pay
attention to traffic signals.
Here
are ways to increase your safety in city driving:
Know the best way to get to where you are going. Get a city map and
plan your trip into an unknown part
of the city just as you would for a
cross-country trip.

Downloaded from www.Manualslib.com manuals search engine 0 Try to use the freeways that rim and crisscross most large cities. You’ll
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.
4-28

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 Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter. Be sure your engine
coolant mix is correct.
You may want to put winter emergency supplies in your vehicle.
Include
an ice scraper, a small brush or broom, a supply of windshield
washer fluid,
a rag, some winter outer clothing, a small shovel, a flashlight,
a red cloth, and a couple
of reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag of sand,
a piece of old
carpet
or a couple of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or /ce
Most of the time, those places where your tires meet the road prob\
ably have
good traction.
However, if there
is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have a
lot less traction or “grip” and
will need to be very careful.
4-32

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves fuel. When you run
the engine, make it go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat that
you get and it keeps
the battery charged. You will need a well-charged battery (or batteries)
to
restart the vehicle, and possibly for signaling later on with your headlights.
Let the heater run for awhile.
Then, shut the engine
off and close the window almost all the way to
preserve the heat. Start the engine again and repeat this only when you feel
really uncomfortable from the cold. But
do it as little as possible. Preserve
the fuel as long as you can.
To help keep warm, you can get out of the
vehicle and do some fairly vigorous exercises every half hour or
so until
help comes.
Recreational Vehicle To wing
(Four-wheel Drive
Only)
If your vehicle has 4-wheel drive, you may tow it behind another vehicle
providing it does
not have the optional electronic shift transfer case.
Recreational vehicle towing is not recommended for vehicles
with the optional electronic shift transfer case because the
electronic shift has no neutral position.

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.
