Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See
Airbag Readiness Light
on
page 4‑15for more information.
Notice: If an airbag covering is
damaged, opened, or broken, the
airbag may not work properly.
Do not open or break the airbag
coverings. If there are any
opened or broken airbag covers,
have the airbag covering and/or
airbag module replaced. For the
location of the airbag modules,
see What Makes an Airbag
Inflate?
on page 2‑31. See your
dealer/retailer for service.
Replacing Airbag System
Parts After a Crash
{WARNING
A crash can damage the airbag
systems in your vehicle.
A damaged airbag system may
not work properly and may
not protect you and your
passenger(s) in a crash, resulting
in serious injury or even death.
To help make sure your airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon as
possible. If an airbag inflates, you will need to
replace airbag system parts. See
your dealer/retailer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly.
Have the vehicle serviced right
away. See
Airbag Readiness Light
on page 4‑15for more information.

Instruments and Controls 4-17
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light comes on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer/
retailer.If the check engine light comes on
and stays on, while the engine is
running, this indicates that there is
an OBD II problem and service is
required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:
If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
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:
Modifications 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. Modifications 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 9‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.

Instruments and Controls 4-19
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
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 run
down. 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.Brake System Warning
Light
United StatesCanada
The brake indicator light should
come on briefly as the engine is
started. If it does not come on have
the vehicle serviced by your dealer/
retailer.

Instruments and Controls 4-23
Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on have the
vehicle serviced by your dealer/
retailer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer/retailer.
Fuel Economy Light
For vehicles with the fuel economy
mode light, it comes on when the
eco (economy) switch, located on
the center console near the shifter,
is pressed. For vehicles with a
Driver Information Center (DIC) an
ECO Mode On message displays.
See Fuel System Messages
on
page 4‑32for more information.
Press the switch again to turn
off the light and exit the fuel
saver mode.

Driving Information
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for long
periods of time.
.When road and weather
conditions are appropriate, use
cruise control, if equipped.
.Always follow posted speed
limits or drive more slowly when
conditions require.
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
.Follow recommended scheduled
maintenance.

Driving and Operating 8-5
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non‐dealer/non‐retailer
accessories can affect vehicle
performance. SeeAccessories
and Modifications on page 9‑3.
Steering
Electric Power Steering
(2.4L L4 Engine)
If the engine stalls while driving, the
power steering assist system will
continue to operate until you are
able to stop the vehicle. If power steering assist is lost because the
electric power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
If you turn the steering wheel in
either direction several times until
it stops, or hold the steering wheel
in the stopped position for an
extended amount of time, you may
notice a reduced amount of power
steering assist. The normal amount
of power steering assist should
return shortly after a few normal
steering movements.
The electric power steering
system does not require regular
maintenance. If you suspect
steering system problems, such as
abnormally high steering effort for a
prolonged period of time, contact
your dealer/retailer for service
repairs.
Hydraulic Power Steering
(3.0L V6 Engine)
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until out of the curve, and
then accelerate gently into the
straightaway.

8-8 Driving and Operating
Many of the vehicle design features
that help make the vehicle more
responsive on paved roads during
poor weather conditions also help
make it better suited for off‐road use
than conventional passenger
vehicles. The vehicle does not have
features usually thought to be
necessary for extended or severe
off‐road use such as special
underbody shielding and transfer
case low gear range.
The airbag system is designed to
work properly under a wide range of
conditions, including off‐road usage.
Always wear your safety belt and
observe safe driving speeds,
especially on rough terrain.
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 judgmentcan 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.
Off-roading can be great fun but has
some definite hazards. The greatest
of these is the terrain itself. When
off-road driving, traffic lanes are not
marked, curves are not banked, and
there are no road signs. Surfaces
can be slippery, rough, uphill,
or downhill.
Avoid sharp turns and abrupt
maneuvers. Failure to operate the
vehicle correctly off‐road could
result in loss of vehicle control or
vehicle rollover.
Off-roading involves some new
skills. That is why it is very
important that you read these
driving tips and suggestions to help
make off-road driving safer and
more enjoyable.Before You Go Off-Roading
.Have all necessary maintenance
and service work done.
.Make sure there is enough fuel,
that fluid levels are where they
should be, and that the spare
tire is fully inflated.
.Be sure to read all the
information about all-wheel-drive
vehicles in this manual.
.Make sure all underbody
shields, if the vehicle has them,
are properly attached.
.Know the local laws that apply to
off-roading where you will be
driving or check with law
enforcement people in the area.
.Be sure to get the necessary
permission if you will be on
private land.
