ENGINE
SOON
The amber
Malfunction Indicator
Lamp (SERVICE
ENGINE SOON
Light) is located at the
top
of your instrument
panel.
A computer monitors operation of your fuel, ignition and emission control
systems. This light should come on when the ignition is on, but the engine is
not running,
as a check to show you it is working. If it does not come on at
all, have it fixed right away. If it
stays on, or it comes on while you are
driving, the computer is indicating that
you have a problem. You should
take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on, after awhile\

the emission controls won’t work
as well, your fuel economy
won’t be as good and your engine may not run as smoothly.
This
could lead to costly repairs not covered by your warranty.
If Your Vehicle is Equipped with 08D 11
Certain vehicles are equipped with a new emission diagnostic sy\
stem. You
can
tell whether your vehicle has this system by reading your tune-up l\
abel
located under the hood. If the label says “OBD
11” on it, the following
instructions apply.
Malfunction Indicator Lamp (SERVICE ENGINE SOON Light)
Your vehicle is equipped with an onboard computer which monitors
operation
of the emission control system. This system is called OBD I1
(On-Board Diagnostics-Second Generation) and is intended
to assure that
emissions are at acceptable levels for the life
of the vehicle, helping to
produce a cleaner environment. The “SERVICE ENGINE
SOON’ light
comes on to indicate when service is required. Malfunctions oft\

more serious damage to your vehicle, This system is
also designed to assist
your service technician in correctly diagnosing any malfunction.
The
“SERVICE ENGINE SOON” light should come on, as a check to show
you it is working, when the ignition is on and the engine is not running. This
light will also come during
a malfunction in one of two ways:
Light on steady - indicates a system malfunction has been detected.
Drive the vehicle to the dealer for service at your first opportunity.
Light flashing - indicates a misfire has been detected which may
damage the emission control system. The damage may be reduced by
lowering the vehicle speed, reducing the amount of cargo being hauled
or trailered, avoiding hard acceleration, or by avoiding steep uphill
grades.
If these actions are effective, the light will stop flashing and
remain
on steady. Drive the vehicle to a dealer for service. If the light
continues to flash, stop
the vehicle. Wait for a steady light to come on,
then drive the vehicle to a dealer for service.
These following conditions also may cause the “SERVICE ENGINE
SOON’ light to come on:
Low Fuel/Out of Fuel - As the vehicle starts to run out of fuel the
“SERVICE ENGINE SOON” light may come on as a result of an engine
misfire. Filling your gasoline tank should correct this condition. Make sure
to install the gas cap fully. It will require a few driving trips to turn the light
off.
Poor Quality Fuel
- Be sure to fuel your vehicle with quality fuel. Your
engine may not run efficiently
on poor fuel. Poor fuel may cause stalling,
hesitation or misfire. These conditions may
go away when the engine is
warned-up. However, poor quality fuel may cause the “SERVICE ENGINE
SOON’ light to come on.
Have a dealer check the vehicle. If no problems are found, you may want to
change to another brand of fuel.
Driving Through Standing Water
- Driving your vehicle through puddles
of deep standing water may result in a temporary misfire condition. This
condition will usually correct itself shortly after the electric\
al system dries
out. It will require a few driving trips to turn the light off.

The red charging
system light is above
your oil temperature
gage on your
instrument cluster and
will come on briefly
when
you turn on the
ignition,
but the
engine
is not running,
as a check to show
you
it is working.
It should go out once the engine is running. If it stays
on, or comes on while
you are driving, you may have a problem with the charging system. It could
indicate that you have problems with a generator drive belt, or another
electrical problem. Have it checked right away. Driving while t\
his light is on
could drain your battery.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and air conditioner.
Check Gages Light

Fuel Gage

The fuel gage tells
you about how much
fuel you have
remaining when the
ignition
is on. When
the gage first indicates
empty, you still have a
little fuel left, but you
should get more fuel
soon.

Here are four things that some owners ask about. None of these show a
problem with
your fuel gage:
At the gas station, the gas pump shuts off before the gage reads full.
It takes a little more or less fuel to fill up than the gage indicated. For
example, the gage may have indicated the tank was half full, but it
actually took a little more
or less than half the tank’s capacity to fill the
tank.
The gage moves a little when you turn a corner or speed up.
The gage doesn’t go back to empty when you turn off the ignition.
For your fuel tank capacity, see the Index under “Fluid Capacities.”

warmer air. Turn the knob counterclockwise for cooler air.
The lower knob selects the heater
or air conditioning function and
determines which outlets the air will flow through (instrument panel,
defroster, heater, etc
.).
OFF - This setting turns off all heating functions. Some outside air will
still come
out of the heater outlet whenever the vehicle is moving forward.
MAX A/C - Air inside your vehicle is recirculated to maximize your air
conditioner’s performance and your vehicle’s fuel economy. This setting
cools the air the fastest and should be used to keep “unwanted odors” and/or
dust from entering the vehicle.
NORM A/C - This setting cools outside air and directs it through the
instrument panel vents. This setting is useful for normal cooling on hot
days.
BI-LEV A/C
- Air is delivered through the heater floor vents as well as
the instrument panel vents. This setting is useful in cool weather with bright
sunlight.
VENT
- Airflow is through the instrument panel vents. Set the upper knob
to the temperature desired. This setting
is useful for mild outside
temperatures, when little heating or cooling is desired. The air conditioner
does not run.
HEAT
- Heated air comes out through the heater floor vents and
windshield defroster vents. This setting is useful for cold weather.
BLEND
- Airflow is divided equally between the heater floor vent and the
windshield defroster vents. This setting is useful in cool weather when you
have fog or ice on the windshield or side windows.
DEF - This setting directs most air through the windshield defroster vents
and some through the heater vents. This setting is useful when you have fog
or ice on the windshield.
Engine Coolant Heater (Option)
If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster, to heat the passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.

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
2-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.
Off-Road Driving with Your 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. Surfaces 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.
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. Check to make sure all
underbody shields (if
so equipped) are properly attached. 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-roading
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.

Downloaded from www.Manualslib.com manuals search engine Driving In .Water
Light rain causes no special off-road driving problems. But hea\
vy 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 damage your axle and
other vehicle parts.
If the water isn’t too deep, then drive through it slowly. At fast speeas, 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.
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 th\
e 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.
