If the warning light comes on, there
could be a brake problem. Have
the brake system inspected
right away.
This light comes on briey when the
ignition key is turned to ON/RUN.
If it does not, have it xed so it
will be ready to warn if there is a
problem.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set. See
Parking Brake on page 2-28for
more information. The light stays on
if the parking brake does not
release fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or
it might go closer to the oor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing Your Vehicle
on page 4-40.
{CAUTION
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning
light on can lead to a crash. If the
light is still on after the vehicle
has been pulled off the road and
carefully stopped, have the
vehicle towed for service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes
on briey when the engine is started.
If it does not, have the vehicle
serviced by your dealer/retailer. If
the system is working normally
the indicator light will then go off.
If the ABS light stays on, turn
the ignition off. If the light comes on
while driving, stop as soon as it
is safely possible and turn the
ignition off. Then start the engine
again to reset the system. If the ABS
light stays on, or comes on again
while driving, the vehicle needs
service. If the regular brake system
warning light is not on, the vehicle
still has brakes, but not antilock
brakes. If the regular brake system
warning light is also on, the
vehicle does not have antilock United States

the vehicle’s fuel economy might
not be as good, and the engine
might not run as smoothly.
This could lead to costly repairs
that might not be covered by
the vehicle warranty.
Notice:Modications made to
the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle’s emission
controls and can cause this light
to come on. Modications to
these systems could lead
to costly repairs not covered by
the vehicle warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
on page 5-3.This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when
it is safe to do so, stop the
vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still ashing,
follow the previous steps and
see your dealer/retailer for service
as soon as possible.Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-7. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel
to evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.
If the vehicle has been driven
through a deep puddle of
water, the vehicle’s electrical
system might be wet. The
condition is usually corrected
when the electrical system dries
out. A few driving trips should
turn the light off.
Instrument Panel 3-31

Make sure to fuel the vehicle
with quality fuel. Poor fuel
quality causes the engine not to
run as efficiently as designed
and may cause: stalling
after start-up, stalling when the
vehicle is changed into gear,
misring, hesitation on
acceleration, or stumbling on
acceleration. These conditions
might go away once the engine is
warmed up.
If one or more of these conditions
occurs, change the fuel brand
used. It will require at least
one full tank of the proper fuel to
turn the light off.
SeeGasoline Octane on
page 5-5.
If none of the above have made the
light turn off, your dealer/retailer
can check the vehicle. The
dealer/retailer has the proper test
equipment and diagnostic tools to x
any mechanical or electrical
problems that might have
developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection could
prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in the
ON/RUN and the light is not on.
The vehicle will not pass
this inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not
been completely diagnosed by
the system. The vehicle would be
considered not ready for
inspection. This can happen if
the battery has recently been
replaced or if the battery has rundown. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving. If
this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your
dealer/retailer can prepare the
vehicle for inspection.

When wheel spin occurs as the
vehicle is moving, the driver may
notice a slight shaking or shuddering
of the vehicle. This should be
stopped as soon as possible to
prevent damage to vehicle
components. This is the indication
that a loss of traction is occurring on
this terrain. The operator should:
1. Reduce speed and apply
the brakes.
2. Assess the terrain properly and
adjust vehicle speed and gear
ranges accordingly: Four-Wheel
High position for higher speeds
and Four-Wheel-Low Lock
for more torque and lower
speeds. Transmission 1 (First)
gear is generally recommended.3. Apply slight pressure to the
brake when the shaking or
shuddering sensation is felt,
keeping the vehicle moving in a
controlled manner.
4. Be prepared to alternate between
braking and accelerating through
the adverse terrain.
Getting Familiar with Off-Road
Driving
It is a good idea to practice in an
area that is safe and close to home
before you go into the wilderness.
Off-roading requires some new
and different skills.
Tune your senses to different
kinds of signals. Your eyes need
to constantly sweep the terrain
for unexpected obstacles. Your ears
need to listen for unusual tire or
engine sounds. Use your arms,
hands, feet, and body to respond to
vibrations and vehicle bounce.Controlling the vehicle is the key to
successful off-road driving. One of
the best ways to control the
vehicle is to control the speed.
At higher speeds:
You approach things faster and
have less time to react.
There is less time to scan the
terrain for obstacles.
The vehicle has more bounce
when driving over obstacles.
More braking distance is needed,
especially on an unpaved surface.
{CAUTION
When you are driving off-road,
bouncing and quick changes in
direction can easily throw you
out of position. This could cause
you to lose control and crash.
So, whether you are driving
on or off the road, you and
your passengers should wear
safety belts.
4-18 Driving Your Vehicle

Scanning the Terrain
Off-road driving can take you over
many different kinds of terrain.
Be familiar with the terrain and its
many different features.
Surface Conditions:Off-roading
surfaces can be hard-packed
dirt, gravel, rocks, grass, sand,
mud, snow, or ice. Each of these
surfaces affects the vehicle’s
steering, acceleration, and braking
in different ways. Depending on
the surface, slipping, sliding, wheel
spinning, delayed acceleration,
poor traction, and longer braking
distances can occur.
Surface Obstacles:Unseen or
hidden obstacles can be hazardous.
A rock, log, hole, rut, or bump
can startle you if you are not
prepared for them. Often these
obstacles are hidden by grass,
bushes, snow, or even the rise and
fall of the terrain itself.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?
Will you have to stop suddenly or
change direction quickly?
When driving over obstacles or
rough terrain, keep a rm grip on the
steering wheel. Ruts, troughs, or
other surface features can jerk the
wheel out of your hands.
When driving over bumps, rocks, or
other obstacles, the wheels can
leave the ground. If this happens,
even with one or two wheels,
you cannot control the vehicle as
well or at all.
Because you will be on an unpaved
surface, it is especially important
to avoid sudden acceleration,
sudden turns, or sudden braking.Off-roading requires a different
kind of alertness from driving on
paved roads and highways. There
are no road signs, posted speed
limits, or signal lights. Use
good judgment about what is safe
and what is not.Crossing Obstacles
Approach Angle — a Key to
Mobility
If you encounter a large dip in the
terrain, do not enter straight on;
enter at an angle — 15° minimum
approach (A), 75° maximum
approach angle (B).
