Downloaded from www.Manualslib.com manuals search engine To shift into or out of 4-WHEEL LOW (4L) or
NEUTRAL (N):
1. Slow the vehicle to a roll, about 1 to 3 mph
(2 to 5 km/h) and shift the transmission into
NEUTRAL (N).
2. Shift the transfer case shift lever in one continuous
motion.
Don’t pause
in NEUTRAL (N) as you shift the
transfer case into 4-WHEEL LOW (4L), or the
gears could clash.
Remember that driving
in 4-WHEEL HIGH (4H) or
4-WHEEL LOW (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.
When your headlamps or parking lamps are on, rotate the
thumb wheel next to the headlamp switch up to brighten,
and down to dim, your transfer case indicator light.
Electronic Transfer Case (Option)
If your four-wheel-drive vehicle has the electronic
transfer case, the transfer case switches are below and to
the left of the climate controls.
Use these switches to shift into and out of four-wheel
drive.
You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged
in
two-wheel drive.

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 kmh) 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.

Downloaded from www.Manualslib.com manuals search engine Remember: Anti-lock doesn’t change the time you need
to get your
foot up to the brake pedal or always decrease
stopping distance.
If you get too close to the vehicle in
front of you,
you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead
to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for
you. You may feel the brakes
vibrate,
or you may notice some noise, but this is
normal. On vehicles with four-wheel drive, your
anti-lock brakes wark at all times
-- whether you are
in two-wheel drive or four-wheel drive.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time. 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 eftort.
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.

Downloaded from www.Manualslib.com manuals search engine Suppose you’re steering through a sharp curve. Then you
’ suddenly accelerate. Both control systems -- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand
too
much of those places. You can lose control.
What should you
do if this ever happens? Ease up on the
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 roadconditions. 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 the curve, while your front
wheels are straight ahead.
Try to adjust your speed
so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are
out of the curve, and then
accelerate gently into the straightaway.
Steering. in Emergencies
There are times when steering can be more effective
than braking. For example,
you come over a hill and
find a truck stopped
in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front
of you. You can
avoid these problems by braking
-- if you can stop
in time. But sometimes
you can’t; there isn’t room.
That’s the time for evasive action
-- steering around
the problem.
Your vehicle can petform very well in emergencies like
these. First apply your brakes.’ (See “Braking in
Emergencies” ,earlier in this section.) It is better to
remove as much speed as you can from a possible
collision. Then steer around
the problem, to the left or
right depending on the space available.

start your
left lane change signal before moving out
of the right lane to pass.,When you are far enough
ahead

inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
if
your right outside mirror is convex, the vehicle you

than it really is.)
on two-lane roads. Reconsider before passing the
next vehicle.
Try not to pass more than one vehicle at a time
0 Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
0 If you’re being passed, make it easy for the
following driver to get ahead
of you. Perhaps you
can ease a little to
the right.
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.
4-12

Downloaded from www.Manualslib.com manuals search engine 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.
Driving Guidelines
This multipurpose passenger vehicle is defined as a
utility vehicle in Consumer Information Regulations
issued by the National Highway 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 two-wheel-drive vehicles any more than
low-slung sports cars
are designed to perform
satisfactorily under off-road conditions. If at all
possible, avoid sharp turns or abrupt maneuvers.
As with other vehicles of this type, failure to operate
this vehicle correctly may result in loss
of control or
vehicle rollover.

Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
0 Unsecured cargo on the load floor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by flying objects. Secure the
cargo properly.
0 Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the roof.
Keep cargo in the cargo area as
far forward
and low as possible.
You’ll find other important information in this manual.
See “Vehicle Loading,” “Luggage Carrier” and “Tires”
in the Index. 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:
0
0
0
0
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),
camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch fire from the
heat
of the vehicle’s exhaust system.

Downloaded from www.Manualslib.com manuals search engine Driving Across an Incline
Sooner or later, an off-road trail will probably go across
the incline of a.hill. If this happens,
you have to decide
whether to try to drive across the incline. Here are some
things to consider:
0
0 A hill that can be driven straight up or down may be
too steep to drive across. When you go straight. up or
down a hill, the length of the wheel base (the
distance from the front wheels to the rear wheels)
reduces the 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 wheels) 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.
Surface conditions can be a problem when you drive
across a 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.
0 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
try it might have rolled over.
.
A CAUTION:
Driving 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.

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.
I A CAUTION:
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 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 daniage 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.
L
A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving through water.
