1-27 Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle. Your
dealer and the service manual have information about
servicing your vehicle and the air bag system. To
purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag system. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag system does not need regular maintenance.
Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.

Safety Belt Extender
If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt isn't long enough to fasten, your
dealer will order you an extender. It's free. When you go
in to order it, take the heaviest coat you will wear, so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don't let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your 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.
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 air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
If you've had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn't being used at
the time of the collision.
If an air bag inflates, you'll need to replace air bag
system parts. See the part on the air bag system earlier in
this section.
2-70 Malfunction Indicator Lamp
(Service Engine Soon Light in the United
States or Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with 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
SERVICE ENGINE SOON or CHECK ENGINE light
comes on and a chime will sound 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 a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
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 may cause the SERVICE ENGINE SOON
or CHECK ENGINE light to come on.
Modifications to these systems could lead to
costly repairs not covered by your warranty.
This may also result in a failure to pass a
required Emission Inspection/Maintenance test.
2-72
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
See ªFilling Your Tankº in the Index. It will take a
few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See ªFuelº in the Index. 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, misfiring, 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,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix 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 in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or 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, see your dealer or qualified service center
to prepare the vehicle for inspection.
3-2
Comfort Controls
Air Conditioning with Electronic Controls
With this system, you can control the heating, cooling
and ventilation in your vehicle. The system works best if
you keep your windows closed while using it.
Fan Knob
The left knob regulates the amount of air coming
into the vehicle. To turn the fan off, turn the knob
to OFF. The fan must be on to run the air
conditioning compressor.If the airflow seems very low when the fan knob is turned
to the highest setting, regardless of the mode setting, your
passenger compartment air filter (if equipped) may need to
be replaced. See ªMaintenance Scheduleº and ªPassenger
Compartment Air Filterº in the Index.
Temperature Knob
The right knob changes the temperature of the air
coming through the system. Turn this knob clockwise
(toward red) for warmer air. Turn it counterclockwise
(toward blue) for cooler air.
Mode Push Buttons
The upper row of push buttons control the direction of
airflow. Each button has an indicator which will glow
when the button is pressed.
UPPER: This setting directs air through the
instrument panel outlets.
BI-LEVEL: This setting directs air two ways. Half
of the air is directed through the instrument panel outlets.
Most of the remaining air is directed through the floor
ducts and a little to the defrost and side window vents.
3-7 Manual Control of the Automatic System
If you prefer to manually control the heating, cooling
and ventilation in your vehicle, set the system to the
temperature and fan speed you want. Next, push the
mode button to select your desired airflow direction.
The system will try to maintain the temperature you set
using the mode you select. The following suggestions
will help the system run more efficiently in manual mode.
Fan Button
: The button below the display is used to manually
select the force of air you want. The display will show
the fan speed. Fan control is no longer automatic, but
the system remains in auto temperature control.
If the airflow seems very low when the fan knob is turned
to the highest setting regardless of the mode setting, your
passenger compartment air filter (if equipped) may need to
be replaced. See ªMaintenance Scheduleº in the Index.
Econ Button
Press the ECON button to turn the compressor on and
off. The indicator light is illuminated when the
compressor is off. AUTO will be not be illuminated, but
the system will maintain automatic air delivery and fan
speed control. The system will attempt to control the
temperature without the help of the compressor.Mode Button
The MODE button is used to control the direction of
airflow when the system is not in AUTO. The first press
will display the current airflow direction. Repeated
pressing will cycle through the following air flow
directions shown in the display.
UPPER: This setting directs air through the
instrument panel outlets.
BI-LEV: This setting directs air two ways. Half of
the air is directed through the instrument panel outlets.
Most of the remaining air is directed through the floor
ducts and a little to the defrost and side window vents.
LOWER: This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defrost and side window vents. When using this
mode and RECIRC, the windows may fog up when the
weather is cold and damp. See ªRecirculationº in the
Index for more information.
DEFOG: This setting allows half of the air to go
to the floor ducts and half to the defrost and side
window vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 38F (3.3C). (Even when the
compressor is running, you can control the temperature).
4-40 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, drive belts, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you find them quickly. If you're trailering, it's
a good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.
