Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 505.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. They are probably part
of the airbag system. Be sure to follow
proper service procedures, and make sure
the person performing work for you is
qualied to do so.
The airbag system does not need regular
maintenance.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 447for more
information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.
Also look for any opened or broken airbag
covers, and have them repaired or replaced. The
airbag system does not need regular maintenance.Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
or the airbag covering on the driver’s and
right front passenger’s seatback, or the side
impact airbag covering on the ceiling near the
side windows, the bag may not work properly.
You may have to replace the airbag module
in the steering wheel, both the airbag module
and the instrument panel for the right front
passenger’s airbag, the airbag module
and seatback for the driver’s and right front
passenger’s seat-mounted side impact airbags,
or side impact airbag module and ceiling
covering for the roof-mounted side impact
airbag. Do not open or break the airbag
coverings.

Rear Air Conditioning System
If your vehicle has the rear air conditioning system
it has two fan speed selectors. One fan speed
selector is located in the front overhead console
and the other is located in the headliner above the
second row seats. The rear air conditioning
system is designed to provide cooled air only.
To operate the rear system using the front control,
just turn the knob to the fan position you want.
To use the rear control, rst turn the front control
to AUX, then the rear control can be used to
increase and decrease the airow.
Passenger Compartment Air Filter
The passenger compartment air lter helps remove
dust and pollen from the air entering the vehicle.
Like the vehicle’s engine air cleaner/lter, it
needs to be changed periodically. For how often
to change the passenger compartment air
lter, seeScheduled Maintenance on page 471.
The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 356
for more information on location.
Front ControlRear Control

Use the procedure listed below to replace the
passenger compartment air lter:
1. Open the hood to access the engine
compartment. SeeHood Release on page 355
for more information. Locate the passenger
compartment air lter access panel door.
2. Push the two tabs on the access panel door
towards the windshield.3. While pressing forward, lift the access panel
out of the clipped position and pull towards
the front of the vehicle. This releases the clips
and allows the panel door to be removed.
4. Remove the old lter and insert a new one.
Make sure the arrow on the lter is pointing
toward the passenger compartment.
SeeNormal Maintenance Replacement Parts
on page 482for the correct part number
for the lter.
5. Reverse Steps 1 through 3 to reinstall the
cover.

This light will ash for approximately 60 seconds
and then turn on solid if a problem is detected with
the Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 410
for more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of the
fuel, ignition, and
emission control
systems.
This system is called OBD II (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 check engine light comes on to indicate that
there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may
prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Notice:If you keep driving your vehicle
with this light on, after awhile, the emission
controls might not work as well, your 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 your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and can cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 347.

Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 349. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (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 you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your dealer
can prepare the vehicle for inspection.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.If equipped, this light
tells you if there could be
a problem with your
engine oil pressure.
The light goes on when you turn your key to ON or
START. It goes off once you start your engine.
That’s a check to be sure the light works. If it
doesn’t come on, be sure to have it xed so it will be
there to warn you if something goes wrong.
When the light comes on and stays on, it means
that oil isn’t owing through your engine properly.
You could be low on oil and you might have
some other system problem.
