Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet
the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to
steer and constantly seek
an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not “overdriving”
those conditions. But skids are always possible.
The three types
of skids correspond to your vehicle’s
three control systems.
In the braking skid, your wheels
aren’t rolling. In
the steering or cornering skid, too
much speed or steering
in a curve causes tires to slip and
lose cornering force. And
in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled by easing your foot off
the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second
skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance
will be longer and
vehicle control more limited.
While driving on
a surface with reduced traction, try your
best
to avoid sudden steering, acceleration or braking
(including engine braking
by shifting to a lower gear).
Any sudden changes could cause the tires to slide. You
may not realize
the surface is slippery until your vehicle
is skidding. Learn to recognize warning clues
-- such as
enough water, ice or packed snow on the road to make
a “mirrored surface” -- and slow down when you have
any doubt.
Remember:
Any anti-lock brake system (ABS) helps
avoid only the braking skid.

Downloaded from www.Manualslib.com manuals search engine Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However, it
also raises environmental
concerns.
GM recognizes these concerns and urges
every off-roader to follow these basic rules for
protecting
the environment:
Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
Avoid any driving practice that could damage the
environment -- shrubs, flowers, trees, grasses -- or
disturb wildlife (this includes wheel-spinning,
breaking down trees or unnecessary driving through
streams or over soft ground).
Always carry a litter bag . . . make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open fires (where permitted),
Never park your vehicle over dry grass or other
camp
stoves and lanterns.
combustible materials that
could catch fire from the
heat
of the vehicle’s exhaust system.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to
a remote area. Know the terrain and plan your route.
You are much less likely to get bad surprises. Get
accurate maps of trails and terrain. Try to learn
of any
blocked or closed roads.
It’s also a good idea
to travel with at least one other
vehicle. If something happens to
one of them, the other
can help quickly.
Does your vehicle have a winch? If
so, be sure to read
the winch instructions. In a remote area, a winch can be
handy
if you get stuck. But you’ll want to know how to
use
it properly.
Getting Familiar with Off-Road Driving
It’s a good idea to practice in an area that’s safe and
close
to home before you go into the wilderness.
Off-road driving does require some new and different
driving skills. Here’s what we mean.
Tune your senses
to different kinds of signals. Your
eyes, for example, need
to constantly sweep the terrain
for unexpected obstacles. Your ears need
to listen for
unusual tire or engine sounds. With your arms, hands,
feet and body, you’ll need
to respond to vibrations and
vehicle bounce.

since you’re on an unpaved surface.
When you’re driving off-road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you to lose
control and crash.
So, whether you’re driving on
or off the road, you and your passengers should
wear safety belts.
Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain. You need to be familiar with the terrain and
its
many different features. Here are some things to consider.
Surjizce Conditions. Off-roading can take you over
hard-packed
dirt, gravel, rocks, grass, sand, mud, snow or
ice. Each of these surfaces affects the steering, acceleration
and braking of your vehicle
in different ways. Depending
upon the kind of surface you are on,
you may experience
slipping, sliding, wheel spinning, delayed acceleration,
poor traction and longer braking distances.
Sutfkce Obstacles. Unseen or hidden obstacles can be
hazardous.
A rock, log, hole, rut or bump can startle you
if you’re not prepared for them. Often these obstacles are
hidden by grass, bushes, snow or even the rise and fall of
the terrain itself. Here are some things to consider:
Is the path ahead clear?
0 Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill? (There’s
more discussion of these subjects later.)
0 Will you have to stop suddenly or change
direction quickly?

firm grip
on the steering wheel. Ruts, troughs or other
surface features can jerk the wheel
out of your hands if
you’re not prepared.
When
you drive over bumps, rocks, or other obstacles,
your wheels can leave the ground. If this happens,
even
with one or two wheels, you can’t control the vehicle as
well or at all.
Because
you will be on an unpaved surface, it’s
especially important
to avoid sudden acceleration,
sudden turns or sudden braking,
In a way, off-road driving requires a different kind
of
alertness from driving on paved roads and highways.
There are no road signs, posted speed limits
or signal
lights.
You have to use your own good judgment about
what is safe and what isn’t.
Drinking and driving can be very dangerous on any
road. And this is certainly true for off-road driving.
At the very time you need special alertness and driving
skills, your reflexes, perceptions and judgment can be
affected by even a small amount
of alcohol. You could
have a serious
-- or even fatal -- accident if you drink
and drive or ride with a driver who has been drinking.
See “Drunken Driving” in the Index.
Driving on Off-Road Hills
Off-road driving often takes you up, down or across a
hill. Driving safely
on hills requires good judgment and
an understanding of what your vehicle can and can’t do.
There are some hills that simply can’t be driven,
no
matter how well built the vehicle.
Many hills are simply too steep for any vehicle.
If you drive up them, you will stall. If you drive
down them, you can’t control your speed. If you
drive across them, you
will roll over. You could be
seriously injured
or killed. If you have any doubt
about the steepness, don’t drive the hill.

slow down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull off the road in a safe place
and rest.
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 headlamps, 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 headlamps),
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 headlamps 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 headlamps 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.

Downloaded from www.Manualslib.com manuals search engine Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or
no contact with the road.
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.
Driving Through Deep Standing Water
NOTICE:
r
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that
is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
0 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.
0 Have good tires with proper tread depth.

I
Snow can trap exhaust gases under your vehi I.
This can cause deadly CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill , ,
you. You can’t see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base
of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window
just a little on the side of the
vehicle that’s away from the wind.
This will help
keep
CO out.
You can run the engine to keep warm, but be careful.

Downloaded from www.Manualslib.com manuals search engine 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 as
responsive as your
vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, 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.
During your trip, check occasionally
to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
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.
