1994 CHEVROLET TRACKER tires

Automatic
With automatic freewheeling hubs, you
don’t have to get out of the vehicle to lock
or unlock the hubs.
To lock the hubs:
1. Stop your vehicle.
2. Shift the transfer case to “4H’ or
“4L.”
3. Drive slowly forward and the hubs
will lock.
To unlock the hubs:
1. Stop your vehicle.
2. Drive seven feet (two meters) in the
direction opposite to the direction you
were driving before you stopped.
3. Then, press the clutch if you have a
manual transmission, and shift the
transfer case to
“2H.” The hubs will
unlock.
rransfer Case
?he transfer case shift lever is on the floor
o the right of the driver. Use this lever to
hift into and out of four-wheel drive. An
ndicator light comes on when the transfer
:ase is in
“4H’ or “4L.”
!H: This setting is for driving in most
treet and highway situations. Your front
.xle is not engaged in two-wheel drive.
IH: This setting engages your front axle
o help drive your vehicle. Use “4”’
vhen you need extra traction, such as on
vet or
icy roads, or in most off-road
ituations.
q: Shift to this setting only when your
rehicle needs to
be towed.
4L: This setting also engages your front
axle to give you extra traction, but should
be used only for driving downhill or on
slippery, surfaces when you’re driving
slower than
35 mph (55 km/h).
Remember that driving in
“4H” or “4L”
may reduce fuel economy. Also, driving
in four-wheel drive on dry pavement
could cause your tires to wear faster and
make your transfer case harder to shift.
You can shift from
“2H” to “4H’ or from
“4W’ to “2H” at any speed if your hubs
are locked and your wheels are straight
ahead. Your front axle will engage faster
if you take your foot off the accelerator
pedal for a few seconds as you shift.
To shift into or out of 4L:
1. Stop your vehicle and shift your
transmission to
“N” (Neutral).
2. Shift the transfer case in one
continuous motion.
Don’t pause in
“N’ as you shift into
“4H,” or your gears could clash.

Your Driving and the Road
There’s something else about drinking
and driving that many people don’t know.
Medical research shows that alcohol
in a
person’s system can make crash injuries
worse. That’s especially true for brain,
spinal cord and heart injuries. That means
that if anyone who has been drinking
-
driver or passenger - is in a crash, the
chance of being killed or permanently
disabled is higher than if that person had
not been drinking. And we’ve already
seen that the chance of a crash itself is
higher for drinking drivers.
Control of a Vehicle
You have three systems that make your
vehicle go where you want it to go. They
are the brakes, the steering and the
accelerator. All three systems have to
do
their work at the places where the tires
meet the road.
Sometimes, as when you’re driving on
snow or ice, it’s easy to ask more
of those
control systems than the tires and road
can provide. That means you can lose
control
of your vehicle.
Braking
Braking action involves perception time
and reaction time.
First, you have to decide to push on the
brake pedal. That’s perception
time. Then
you have to bring
up your foot and do it.
That’s reaction
time.
Average reaction time is about 3/4 of a
second. But that’s only an average. It
might be less with one driver and as long
as two or three seconds or more with
another. Age, physical condition,
alertness, coordination, and eyesight all
play a part.
So do alcohol, drugs and
frustration. But even in
3/4 of a second, a
vehicle moving at
60 mph (100 km/h)
travels
66 feet (20 m). That could be a lot
of distance in an emergency,
so keeping
enough space between your vehicle and
others is important.
And,
of course, actual stopping distances
vary greatly with the surface of the road
(whether it’s pavement or gravel); the
condition of
the road (wet, dry, icy); tire
tread; and the condition of your brakes.
Avoid needless heavy braking. Some
people drive in spurts
- heavy
acceleration followed by heavy braking
- rather than keeping pace with traffic.

Your Driving and the Road
that happens, release enough pressure on
the brakes to get the wheels rolling again
so that you can steer.
With the four-wheel drive option, you
won’t have anti-lock braking when you
shift into four-wheel drive. But
you will
have regular braking. When you shift
back into two-wheel drive, you will have
anti-lock again.
Braking in Emergencies
At some time, nearly every driver gets
into a situation that requires hard braking.
You have the rear-wheel anti-lock braking
system. Your front wheels can stop rolling
when you brake
very hard. Once they do,
the vehicle can’t respond to your steering.
Momentum
will carry it in whatever
direction it was headed when the front
wheels stopped rolling. That could be off
the road, into the very thing you were
trying to avoid, or into traffic.
So, use a “squeeze” braking technique.
This will give you maximum braking
while maintaining steering control.
You
do this by pushing on the brake pedal
with steadily increasing pressure. When
you do, it will help maintain steering
control. In many emergencies, steering
can help you more than even the
very best
braking.

Steering
Power Steering
If you lose power steering assist because
the engine stops or the system is not
functioning, you can steer but
it will take
much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a
reasonable speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here’s why:
Experienced driver or beginner, each of
us is subject to the same laws of physics
when driving on curves. The traction of
the tires against the road surface makes
it
possible for the vehicle to change its path
when you
turn the front wheels. If there’s
no traction, inertia will keep the vehicle
going
in the same direction. If you’ve
ever tried to steer a vehicle on wet ice,
you’ll understand this.
The traction you can get in a curve
depends on the condition of your tires and
the road surface, the angle at which
the
curve is banked, and your speed. While you’re
in a curve, speed
is the one factor
you can control.
Suppose you’re steering through a sharp
curve. Then
you suddenly apply the
brakes. Both control systems
- steering
and braking
- have to do their work
where the tires meet the road. Adding the
hard braking can demand too much at
those places.
You can lose control.
The same thing can happen if you’re
steering through a sharp curve and you
suddenly accelerate. Those two control
systems
- steering and acceleration -
can overwhelm those places where the
tires meet
the road and make you lose
control.
What should
you do if this ever happens?
Ease up on the brake or accelerator pedal,
steer the vehicle the way you want it to
go, and slow down.
Speed limit signs near curves warn that
you should adjust your speed. Of course,
the posted speeds are based on good
weather and road conditions. Under less
favorable conditions you’ll want to go
slower.
If you need to reduce your speed as you
approach a curve, do
it before you enter
ProCarManuals.com

loss of Control
Let's review what driving experts say
about
what happens when the three
control system (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 Geo's three control systems. In the
braking skid your wheels are.n'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 011' 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. 41ways be
ready for
;I sccond 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
EO a
lower gear).
Any sudden changes could
cause the tires to slide. You may
not
realize the surface is slippery until yout-
vehicle is skidding. Learn
to recognize
warning clues
~ such as enough water,
ice or packed snow
on the road to make ;1
"nlir~-or.ed surf'rlce" - and slow down
when you have any doubt.
Remember: The rex-wheel anti-lock
braking system (RWAL) helps avoid
only
a rear braking skid. In a braking skid
(where the front wheels are
no longer rolling),
release enough pressure
on the
brakes to get the front wheels rolling
again. This restores steering control. Push
the brake pedal down steadily when you
have
to stop suddenly. As long as the
I'ront wheels are rolling,
you will have
sleering control.
Driving Guidelines
This multipurpose passenger vehicle is
defined as a utility vehicle in Consumer
Information Regulations issued
by the
National I-lighway Traffic Safety
Administration (NHTSA)
of the United
States Department of Transportation.
Utility vehicles have higher ground
clearance and a narrower track to make
them capable of performing
in a wide
variety
of off-road applications. Specific
design characteristics give them a higher
center of gravity than ordinary cars. An
advantage
of the higher ground clearance
is
a better view of the road allowing you
to anticipate problems. They are not
designed for cornering
at the same speeds
as conventional 2-wheel drive vehicles
any no re than low-slunl 7 .'p '-, orts cars are
designed
to perform satisfitctorily under
off-road conditions.
If at all possible,
avoid shurp turns or abrupt maneuvers.

to operate this vehicle correctly may
result
in loss of control or vehicle

Off-Road Driving with
Your Geo 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. Surfwes
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.
=. .lo8
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-roacting
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 heavies1 things should
be on the
load floor and forward of your rear
axle. Put heavier items
as far forward
as you can.
e Be sure the load is secured properly,
so driving on the off-road terrain
doesn’t
toss things around.
You’ll find other important information in
this manual. See “Vehicle Loading” and
”Tires”
in the Index.

likelihood the vehicle will tumble end
over end.
But when you drive across
an
incline. the much more narrow
track width
(the distance between the
left and right whecls) may not prevent
the vehicle from tilting and rolling
over.
Also, driving across an incline
puts more weight on the downhill
wheels. This could cause a downhill
slide or a rollover.
Surfkce conditions can be
a problem
when you drive across
il hill. Loose
gravel, muddy spots. or even wet
grass can cause your tires
to slip
sideways, downhill.
If the vehicle
slips sideways.
it can hit something
that
will trip it (a rock, a rut, etc.) and
roll over.
Hidden obstacles can make the
steepness
of the incline even worse. If
you drive across a rock with the uphill wheels, or
if the downhill wheels drop
into
a rut or depression. your vehicle
can
tilt even more.
For reasons like these, you need
to decide
carefully whether
to try to drive across an
incline. Just because the trail goes across
the incline doesn’t mean
you have to
drive it. The last vehicle to iry it might
have rolled over.
Road
Drivihg across an incline that’s too
steep
will make your vehicle roll
over. You could be seriously injured
or killed. If you have any doubt about
the steepness
of the incline, don’t
drive across it. Find another route
instead.
Q: What if I’m driving across an
incline that’s not too steep, but I hit
some loose gravel and start to slide
downhill. What should
I do‘?
A: If you feel your vehicle starting to
slide sideways, turn downhill. This
should help straighten out the vehicle
and prevent the side slipping. However
a much better way to prevent this is to
get
out and “walk the come” so you
know what the surface is like bcforc
you drive it.
Stalling on an Incline
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.

A CAUTION:
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. .4nd
if
you do get moving, poor steering and
difficult braking can cause
you to slide
out of control.
A CAUTION:
Driving in Water
Light rain causes no special off-road
driving problems. But heavy rain can
mean tlash flooding, and tlood
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 il - 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. ,4nd, as

Your Driving and the Road
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.
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.
4 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.
Since you can't see as well,
you may
need to slow down and keep more space between
you and other vehicles.
