Ashtrays and Cigarette Lighter
Your vehicle may have a cigarette lighter which is
located on the left side
of the engine cover console.
To use the lighter, press it in ail the way and let go.
When it’s done heating, it will pop back out by itself.
Notice: Don’t hold a cigarette lighter in with
your hand while
it is heating. If you do, it won’t
be able to back away from the heating element when
it’s ready. That can make
it overheat, damaging
the lighter and the heating element.
Notice: When using the cigarette lighter as an
accessory power outlet, maximum electrical load must not exceed 20 amps. Always turn
off any
electrical equipment when not
in use. Leaving
electrical equipment on for extended periods will
drain your battery. The
front ashtray
is located above the passenger’s side
front cupholder. To remove the front ashtray, open it
and gently pull it slightly past its stop.
To remove the ashtray on the sliding door, open it,
then press down
on the inside tab and pull it out.
You may have another ashtray on the driver’s sidewall.
Press the right side to turn the ashtray around for use.
To remove the ashtray, open it and gently pull it off
the hinge.
Notice: Don’t put papers or other flammable
items into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing
a damaging fire.
3-1 7

Be sure to keep the area under the front seats clear of
any objects
so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate-control
system. For information
on ventilation, see “Outlet
Adjustment” listed later in this section.
Rear Climate Control System
Rear Window Defogger
Your vehicle may have a rear window defogger that
uses a warming grid
to remove fog or frost from the
rear window.
The rear window defogger will only work when the
ignition is in
RUN.
Press this button to turn
the rear window defogger
on or off. Be sure to
clear as much snow from
the window as possible.
The rear window defogger will turn
off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice: Don’t use a razor blade or something else
sharp on the inside of the rear window. If you do,
you could cut or damage the defogger and the repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or
is a
problem with one of your vehicle’s functions.
As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the engine
just to let you know they’re working.
If you are familiar
with this section, you should not be alarmed when
this happens. Gages
can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one
of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
3-23

If the air bag readiness light stays on after you start the
vehicle or comes on when
you are driving, your air
bag system may not work properly. Have your vehicle
s iced right away.
Charging System
If the air bag readiness light stays on after you
start your vehicle,
it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate
in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
RUN.
If the light doesn’t come on then, have it fixed so
it will be ready to warn you if there is a problem.
Light
This light should come on
briefly when you turn on
the ignition, before starting the engine, as a check
to show you it is working.
After the engine starts, the light should go out.
if it stays
on or comes on while you are driving, you may have
a problem with your charging system. It could indicate a
problem with the generator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on,
it helps to turn off all your accessories, such as
the radio and air conditioner.
3-27

Voltmeter Gage
When your engine is not
running, but the ignition is
on (in the RUN position),
the gage shows your
battery’s state of charge
in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between
the low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition
is normal since the
charging system
is not able to provide full power at engine
idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the readings
in either warning zone.
If you must drive, turn off
all unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning
light will come on when you set your parking brake.
The light will stay on
if your parking brake doesn’t
release fully.
If it stays on after your parking brake is
fully released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
3-28

BRAKE
This light should come on
briefly when you turn
the ignition key to
RUN.
If it doesn’t come on then,
have it fixed
so it will
be ready to warn you
if there’s a problem.
If the light comes on while you are driving, pull
off the
road and stop carefully. You may notice that the pedal
is harder to push. Or, the pedal may
go closer to the
floor. It may take longer to stop. If the light is still
on, have the vehicle towed for service. See
Towing
Your Vehicle on page 4-29.
I
You- -)rake system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
Anti-Lock Brake System
Warning light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on
for several seconds.
That’s normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t have
anti-lock brakes and there’s a problem with your regular
brakes. See “Brake System Warning Light” earlier in
this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN.
If the light doesn’t come on then, have it fixed so
it will be ready to warn you if there is a problem.
3-29

Engine Coolant Temperature Gage
This gage shows
the engine coolant
temperature.
If the
gage pointer moves
to the red area, your
engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
See
Engine Overheating on page 5-31.

Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
3-30

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,
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 may cause
this 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.
This light should come on, as a check to show you
it
is working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
e
e Light Flashing - A misfire condition has been
detected.
A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Dealer or qualified service center
diagnosis and service may be required.
Light On Steady
- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis
and service may be required.
