Notice: Adding some electrical equipment to your
vehicle can damage
it or keep other things from
working as they should. This wouldn’t be covered by
your warranty. Check with your dealer before adding electrical equipment, and never use anything
that exceeds the amperage rating.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice: Power outlets are designed for accessory
plugs only.
Do not hang any type of accessory
or accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.
Ashtrays and Cigarette Lighter
Push down on the cover to reveal the front ashtray.
To clean the ashtray,
lift it out by pulling on the finger
holes on each side.
On models without a console, an ashtray is located
underneath the instrument panel.
To clean the ashtray,
lift it out by pulling up on the tabs on either side.
It snaps back into place.
To open a rear ashtray, lift the cover
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.
The cigarette lighter is located next to the storage tray.
To use a lighter, just push the center in all the way
and let
it go. When it is ready, the center will pop back
out by itself. Pull out the entire unit to use it.
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.
The cigarette lighter will only operate when the ignition
key is in
ON and for 10 minutes after turning the
ignition
OFF. If you would like the lighter to operate
regardless of ignition position, and for extended periods
of time, see “Engine Compartment Fuse Block under
Fuses and Circuit Breakers on page 5-92 or see
your dealer.

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
DIG that works along with
the warning lights and gages. See
Driver lnformation
Center
(DIC) on page 3-57.
The volume of your vehicle’s warning chimes can be
adjusted. For information see
Chime Level Adjustment
on page 3- 10 1.
3-34

Battery Warning Light
If your vehicle has this
feature, this light will come
on briefly when you
start the vehicle, as a
check to show you
it is working; then it should
go out.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
Have
it checked right away. Eriving while this light is
on could drain your battery and result in a vehicle that
may stall.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and climate control system.
Some instrument panel clusters with a voltmeter gage
do not have a battery warning light. They have a CHECK
GAGES warning to indicate a problem.
On vehicles with a DIC, a CHECK CHARGE SYSTEM
message will be displayed and a warning chime will
sound. See
DIC Warnings and Messages on page 3-60
for more information.
Voltmeter Gage
You have a voltmeter
unless you have the
supercharged engine.
When the ignition is running, the gage shows the
condition
of the charging system. Readings between the
shaded warning zones indicate the normal operating
range. Readings in the shaded warning zones indicate a
possible problem in the electrical system.
On vehicles with the systems monitor, the CHECK
GAGES light will also come on, and a warning chime
will sound
if there is a problem in the electrical system.
Have your vehicle serviced immediately.
3-41

The optional Traction Control System is active and
is limiting wheel spin. You may feel the system
working, but this is normal. Slippery road conditions
may exist,
so adjust your driving accordingly.
If the LOW TRAC light comes on, slippery road
conditions may exist,
so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage
United States Canada
To prevent engine overheating, the air conditioning
compressor will turn
off automatically just prior to the
gage pointer entering the shaded area. As the
engine cools down, the air conditioning compressor will
automatically turn back on. On vehicles equipped
with the DIC, the message ENGINE HOT
... NC
DISABLED will appear in the DiC display and a warning
chime will sound.
If the gage pointer moves into the shaded area, your
engine is too hot.
On vehicles equipped with the
systems monitor, the CHECK GAGES light will come
on
and a warning chime will sound.
On vehicles with a
DIC, a CHECK GAGES
TEMPERATURE message will be displayed and a
warning cnime wili sound.
See DIC bVamiisgs and
Messages on page 3-60 for more information.
See
Engine Overheating on page 5-29, for information
on what to do
if your engine overheats.
This gage shows the engine coolant temperature.
3-45

Tire Pressure Light
The check tire pressure system can alert you to a large
change in the pressure of one tire.
TIRE PRESS
After the system has been
properly calibrated, the
TIRE PRESS light
will come on
if a pressure
difference (low pressure) is detected in one tire.
The light will stay on until you turn off the ignition or
reset (calibrate) the system. See
Check Tire Pressure
System on page
5-64.
The TIRE PRESS light also comes on briefly when you
turn your ignition key to START.
If the light doesn’t
come
on then, have it fixed so it will be there to tell you
if the pressure in a tire is low.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-43.
On vehicles with the optional Driver Information Center
(DIC), a
CHECK TIRE PRESSURE message replaces
the TIRE
PRESS light when the system detects a
pressure difference (low pressure) in one tire. See
DIC
Warnings and Messages on page 3-60 for more
information.
