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:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating. Do not
use anything other than the cigarette lighter in the
heating element.Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
FAN:Turn the left knob clockwise or counterclockwise
to increase or decrease the fan speed. Push this
knob to turn the fan on and off. The fan must be on in

To change the current mode, select one of the following:
6(FLOOR):This mode directs most of the air to
the oor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed
to the windshield.
)(Bi-Level):This mode directs about half of the air
to the instrument panel outlets, and then directs
most of the remaining air to the oor outlets. There is
also a small amount of air directed to the windshield and
outboard outlets (for the side windows). This mode
directs cooler air to the upper outlets and warmer air to
the oor outlets.
H(Vent):This mode directs air to the instrument
panel outlets.
?RECIRC (Recirculation):This mode keeps
outside air from coming in the vehicle. It can be used to
prevent outside air and odors from entering your
vehicle or to help heat or cool the air inside your vehicle
more quickly. Press this button to turn the recirculation
mode on or off. When the button is pressed, an indicator
light will come on. The recirculation mode cannot be
used with the FRONT defrost mode.
#A/C (Air Conditioning):Press this button to turn
the air conditioning compressor on and off. When A/C is
pressed, an indicator light in the button will come on
to let you know that air conditioning is activated. If your
climate control system is off, you may also turn it
back on in vent mode by selecting the A/C button.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce the
time it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.

your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.

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 briey when you start the
engine just to let you know they are 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 is 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 are a big help.
Your vehicle may also have a DIC that works along with
the warning lights and gages. SeeDriver Information
Center (DIC) on page 3-59.
The volume of your vehicle’s warning chimes can be
adjusted. For information seeChime Level Adjustment
on page 3-103.
Instrument Panel Cluster
The instrument panel clusters are designed to let you
know at a glance how your vehicle is running. You
will know how fast you are going, how much fuel you
are using, and many other things you will need to drive
safely and economically.
3-33

Your vehicle is equipped with one of these instrument panel clusters, which includes indicator warning lights and
gages that are explained on the following pages.

Tachometer
The tachometer shows your engine speed in revolutions
per minute (rpm).
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts.
The safety belt light will
also come on and stay on
for several seconds,
then ash for several more.
If the driver’s belt is already buckled, the light will come
on briey, but the chime will not sound.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows airbag or the airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensors, the airbag modules, the wiring and the crash
sensing and diagnostic module. For more information on
the airbag system, seeAirbag System on page 1-47. V6 Engine
V8 Engine
3-38

This light will come on when you start your vehicle, and
it will ash for a few seconds. Then the light should
go out. This means the system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start your
vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to ON. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.
On vehicles with the DIC, a SERVICE airbag message
will be displayed when there is a problem with the
airbag system. SeeDIC Warnings and Messages on
page 3-62for more information. United States and V6 in

Voltmeter Gage
When your engine is not running, but the ignition key is
turned to ON, this gage shows the state of the battery
charge in DC volts.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.
On vehicles with a DIC, a CHECK CHARGE SYSTEM
message will be displayed and a warning chime will
sound if there is a problem in the electrical system. Have

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into two
parts. If one part is not 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 is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to ON. If it does not come on then, have it
xed so it will be ready to warn you if there is a
problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If you try to drive off with the parking
brake set, a chime will also come on until yourelease the parking brake. If the light stays on after your
parking brake is fully released, it means you have a
brake problem.
If you have the optional Driver Information Center (DIC),
a PARK BRAKE SET message will be displayed
while the parking brake is set.
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
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-34.
{CAUTION:
Your brake 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 have pulled off the road and
stopped carefully, have the vehicle towed for
service. United States
