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 ªoverdrivingº 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
ªmirrored surfaceº
-- 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.

4-19 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.
Surface 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 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?

Will the surface texture change abruptly up ahead?

Does the travel take you uphill or downhill?
(There's more discussion of these subjects later.)

Will you have to stop suddenly or change
direction quickly?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.
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 ªDrunken Drivingº in the Index.

4-21 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 firm 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.
CAUTION:
Turning 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.

Ease up on your speed as you approach the top
of the hill.

Attach a flag to the vehicle to make you more visible
to approaching traffic on trails or hills.

Sound the horn as you approach the top of the hill to
let opposing traffic know you're there.

Use your headlamps even during the day. They make
you more visible to oncoming traffic.
CAUTION:
Driving to the top (crest) of a hill at full speed
can cause an accident. There could be a drop
-off,
embankment, cliff, or even another vehicle.
You could be seriously injured or killed. As you
near the top of a hill, slow down and stay alert.

4-22
Q:What should I do if my vehicle stalls, or is
about to stall, and I can't make it up the hill?
A:If this happens, there are some things you should
do, and there are some things you must not do.
First, here's what you should do:

Push the brake pedal to stop the vehicle and
keep it from rolling backwards. Also, apply the
parking brake.

If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and
slowly back down the hill in REVERSE (R).

If your engine has stopped running, you'll need
to restart it. With the brake pedal pressed and the
parking brake still applied, shift the transmission to
PARK (P) (or, shift to neutral if your vehicle has a
manual transmission) and restart the engine. Then,
shift to REVERSE (R), release the parking brake,
and slowly back down the hill as straight as possible
in REVERSE (R).
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 not 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 pressing the clutch, if you have
a manual transmission) to ªrev
-upº 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.

4-28 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.
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.

4-30 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.

4-41
What's the worst time for this? ªWet ice.º Very cold snow or
ice can be slick and hard to drive on. But wet ice can be even
more trouble because it may offer the least traction of all.
You can get wet ice when it's about freezing (32F; 0C)
and freezing rain begins to fall. Try to avoid driving on wet
ice until salt and sand crews can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Accelerate gently. Try not to break the fragile traction.
If you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.Unless you have the anti
-lock braking system, you'll
want to brake very gently, too. If you do have anti
-lock,
see ªAnti
-Lockº in the Index. This system improves
your vehicle's stability when you make a hard stop on a
slippery road. Whether you have the anti
-lock braking
system or not, you'll want to begin stopping sooner than
you would on dry pavement. Without anti
-lock brakes,
if you feel your vehicle begin to slide, let up on the
brakes a little. Push the brake pedal down steadily to
get the most traction you can.
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.

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.

4-45
Follow these steps:
1. Set the parking brake.
2. Shift your automatic transmission into PARK (P),
or your manual transmission to SECOND (2).
3. With the ignition key in the ON position, move the
transfer case to NEUTRAL and make sure the
4WD light on the instrument panel cluster is off.
See ªFour
-Wheel Driveº in the Index.
4. Turn the ignition key to ACC to unlock the
steering wheel.
5. Release the parking brake.
NOTICE:
If you tow your four-wheel-drive vehicle from
the front, make sure to move the transfer case
into NEUTRAL or your vehicle could be badly
damaged and the damage would not be covered
by your warranty.
Stop towing every 200 miles (300 km) and start the
engine. Leave the transfer case shift lever in NEUTRAL.
Shift your automatic transmission to DRIVE (D); leave
a manual transmission in SECOND (2) with the clutch
engaged. Run the engine at medium speed for one minute
to circulate oil in the transfer case. Turn the ignition key
to ACC. Now, you can continue towing your vehicle.
NOTICE:
The front wheels transmit shocks during towing.
The steering column may not be strong enough to
withstand the shocks. Always unlock the steering
wheel before towing.
NOTICE:
Make sure that the towing speed does not
exceed 55 mph (90 km/h), or your vehicle could
be badly damaged.
