Cruise Control (If Equipped)
With cruise control, you can
maintain
a speed of about
25 mph (40 krn/h) or more
without keeping your foot
on the accelerator. This
can
really help on long trips.
Cruise control
does not
work at speeds below about
25 rnph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut
off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will
shut off.

Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
don‘t use your cruise control on winding
roads or in heavy traffic.
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.

The anti-lock system can change the brake pressure
faster
than any driver could. The computer is
programmed to make the most of available tire and
road conditions. I
Here’s how anti-lock works. Let’s say the road is wet.
You‘re driving safely. Suddenly
an animal jumps out in
front of you.
You slam
on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at the
rear wheels. You
can steer
around the obstacle while braking hard.
As you brake. your colnputer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
4-8

Suppose you're steering througl1 a shxp CLII-V~. Tllen you
suddenly accelemtc.
Both control systems -- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration cim ciemand too
much of those places. You can lose control.
What sho~~ld you do
if this ever happens'! Ease LIP on the
accelerator pedal. steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near CLI~V~S warn that ~OLI shoulcl
adjust your speed. Of co~~rse. 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 yo111- speed as you approach a
curve, do it before ~OLI enter the curve7 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
4-10

An emergency like this requires close attention and a
quick decision. If yo^^ are holding the steering wheel at
the recommended 9 and 3 o'clock positions. you can
turn
it a full 180 degrees very quickly without removing
either hand.
But you have to act fast, steer quickly, and
just
as quickly straighten the wheel once you have
avoided the object.
The fact that
SLICII emergency situations are always
possible is
a good rwson to practice defensive driving at
all times and wear safety belts properly.
Off-Road Recovery
I OFF- ROAD RECOVERY / ,+
-/// edge of paved surface
If the level of the shoulder is only slightly below the
pwement, recovery should
be fairly easy. Ease off the
accelerator and then,
if there is nothing in the way, steer so
that your vehicle straddles the edge of the pavement. YOLI
can turn the steering wheel up to one-quarter turn until the
right front
tire contacts the pavement edge. Then turn your
steering wheel
to go straight down the roadway.
4-11

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 il 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 lilnited.
While driving
on a surface with reduced traction. try
your best to avoid sudden steering, acceleration
or
braking (inclucling engine braking by shifting to a lower
gear).
Any sudden changes could cause the tircs lo slide.
You may not realize the surface is slippery until yo11r
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 yo11
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 dcsigned
to perform satisfactorily under off-road
conditions.
If at all possible. avoid shalp turns or abrupt
manewers. As with other vehicles
of this type. failure to
operate this vehicle correctly may result
in loss of control
or vehicle rollover.

Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain. You need to be fimilix with the terrain and its
many different features. Here are some things
to consider.

you may experience slipping. sliding, wheel spinning,

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,

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
1-oad. And this is certainly true for off-nmi driving. At
the very tirne you need special alertness and driving
skills, your reflexes. perceptions and judgment can be
affected by
wen a small amount of alcohol. You could
have
:I serious -- or even fital -- accident if you drink
and drivc or ride with a drivel- who has been drinking.
