Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
Press this button
to turn
the rear window defogger
on or
off
An indicator light in the button will come on to let you
know that the rear window defogger is activated.
The rear window defogger will turn
off approximately 10
minutes after the button is pressed. If you need
additional warming time, press the button again.
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.

decal or anything similar to the defogger grid.
Do not attach a temporary vehicle license, tape, a decal
or anything similar
to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel
to direct the airflow.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent setting
to direct outside
air through your vehicle.
Your vehicle’s ventilation system supplies outside air
to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle and out the air exhaust
valves.
Outside air will also enter the vehicle when the heater
or the air conditioning compressor is running, unless you
have the recirculation button pushed in.

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.
Your vehicle may also have a Driver lnformation Center
(DIC) that works along with the warning lights and
gages. See
Driver lnformation Center (DE) on
page
3-43.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Simply press the trip odometer button.
You may wonder what happens
if your vehicle needs
a new odometer installed. The new one will be set to the
correct millage total of the old odometer.
Trip Odometer
I
The trip odometer is part of the Driver Information
Center (DIC). For vehicles without a DIC, press the stem
located on the instrument panel cluster
to display the
trip odometer. Press and hold the stem to reset the trip
odometer once it is displayed.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice: Do not operate the engine with the
tachometer in the shaded warning area,
or engine
damage may occur.
Safety Belt Reminder Light
When the key is turned to RUN, a chime will come on
for several seconds
to remind people to fasten their
safety belts, unless the driver’s safety belt is already
buckled.
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer
to zero.
3-30

The safety belt light will also come
on and stay on
for several seconds, then it
will flash for several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you
if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air baa
system, see
Air Bag Systems on page 1-46.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then
the light should
go out.
This means the system is
ready. 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
serviced right away.
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.

Charging System Light
7 will come on briefly when
The
charging system light
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
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 this light is on could drain your
battery. a
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.
Voltmeter Gage
When your engine is not
running, but the ignition is
on (in
RUN), this 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.
3-32

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 idling 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 reading
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. 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.

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.
A chime
may also sound when the light comes on. 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.
3-33

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

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.
I
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.
A chime may also
sound when the light
comes on.
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 on page 3-33
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.
