1998 CHEVROLET TRACKER steering

Downloaded from www.Manualslib.com manuals search engine Loss of Control
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.
If you have the anti-lock braking system, remember: It
helps avoid only the braking
skid. If you do not have
anti-lock, then in a braking skid (where the wheels are
no longer rolling), release enough pressure on the brakes to get
the wheels rolling again. This restores steering
control. Push the brake pedal down steadily when you
have
to stop suddenly. As long as the wheels are rolling,
you will have steering control.

Downloaded from www.Manualslib.com manuals search engine Controlling your vehicle is the key to successful
off-road driving. One of the best ways to control your
vehicle is to control your speed. Here are some things to
keep in mind. At higher speeds:
you approach things faster and you have less time to
scan the terrain for obstacles.
0 you have less time to react.
you have more vehicle bounce when you drive
over obstacles.
you’ll need more distance for braking, especially
since you’re on an unpaved surface.
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.
Surfiace 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.
Surface Obstacles. Unseen or hidden obstacles can be
hazardous. A rock, log, hole, rut or bump can startle you if
1 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? 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 Will the surface texture change abruptly up ahead?
control and crash. So, whether you’re driving on Does the travel take you uphill or downhill? (There’s
or off the road, you and your passengers should more discussion of these subjects later.)
wear safety belts. Will you have to stop suddenly or change
direction quickly?

Downloaded from www.Manualslib.com manuals search engine When you drive over obstacles or rough terrain, keep a
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.
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.
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.
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.

Downloaded from www.Manualslib.com manuals search engine Approaching a Hill
When you approach a hill, you need to decide if it’s one
of those hills that’s just too steep to climb, descend or
cross. Steepness can be hard to judge. On a very small
hill, for example, there may be a smooth, constant
incline with only a small change in elevation where you
can easily see all the way to the top. On a large hill, the
incline may get steeper as you near the top, but you may
not see this because the crest
of the hill is hidden by
bushes, grass or shrubs.
Here are some other things to consider
as you approach
a hill.
Is there a constant incline, or does the hill get sharply
Is there good traction on the hillside, or will the

Is there a straight path up or down the hill so you

path (boulders, trees, logs or ruts)?
What’s beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and walk the
hill if you don’t know. It’s the smart way to find out.
Is the hill simply too rough? Steep hills often have
ruts, gullies,
troughs and exposed rocks because they
are more susceptible to the effects of erosion.
Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.
Use a low gear and get a fm grip on the steering wheel.
Get a smooth start up the hill and try to maintain your
speed. Don’t use more power than you need, because
you don’t want your wheels to
start spinning or sliding.
Try to drive straight up the hill if at all possible. If
the path twists and turns, you might want to find
another route.
I A CAUTION:
lhrning or driving across steep hills can be
dangerous.
You could lose traction, slide
sideways, and possibly roll over.
You could be
seriously injured or killed. When driving up hills,
always try to go straight
up.
4-20

Downloaded from www.Manualslib.com manuals search engine As you are backing down the hill, put your left hand
on the steering wheel at the
12 o’clock position. This
way, you’ll be able to tell if your wheels are straight
and maneuver as you back down. It’s best that you
back down the hill with your wheels straight rather
than in the left or right direction. Turning the wheel
too far to the left or right will increase the possibility
of a rollover.
Here
are some things you must nut do if you stall, or are
about to stall, when going up a hill.
Never attempt to prevent a stall by shifting into
NEUTRAL
(N) (or depressing the clutch, if you
have a manual transmission) to “rev-up” the engine
and regain forward momentum.
This won’t work.
Your vehicle will roll backwards very quickly and
you could go out of control.
Instead, apply the regular brake to stop the vehicle. Then apply the parking brake. Shift to
REVERSE (R), release
the parking brake, and slowly back straight down.
Never attempt to turn around if you are about to stall
when going up a hill. If the hill is steep enough to
stall your vehicle, it’s steep enough to cause you to
roll over if you turn around.
If you can’t make it up
the hill, you must back straight down the hill.
Suppose, after stalling, I try to back down
the hill and decide
I just can’t do it. What
should
I do?
A: Set the parking brake, put your transmission in
PARK
(P) (or the manual transmission in
FIRST
(1)) and turn off the engine. Leave the
vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would
take if it rolled downhill. Do not shift the transfer
case to NEUTRAL, (N) when you leave the vehicle.
Leave it in some gear.

Downloaded from www.Manualslib.com manuals search engine Driving in Mud, Sand, Snow or Ice
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. 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 on frozen lakes, ponds or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice. Your
vehicle could fall through the ice and you and
your passengers could drown. Drive your vehicle
on safe surfaces only.

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
L ..
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.
4-29

Downloaded from www.Manualslib.com manuals search engine Remember, unless you have anti-lock, if you brake so
hard that your wheels stop rolling, you’ll just slide.
Brake
so your wheels always keep rolling and you can
still steer.
Whatever your braking system, allow greater
following distance
on any slippery road.
0 Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps of trees, behind buildings or under bridges.
Sometimes the surface of a curve or
an overpass may
remain icy when the surrounding roads are clear.
If
you see a patch of ice ahead of you, brake before you
are on it.
Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle unless you know for sure that you are near help
and you can hike through the snow. Here are some
things to do to summon help and keep yourself and your
passengers safe:
