Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or in
different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can not see
or smell. It can cause unconsciousness
and death.
You might have exhaust coming in if:
Your exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over
road debris.
Repairs were not done correctly.
Your vehicle or exhaust system had been
modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows down to
blow out any CO; and
Have your vehicle xed immediately.
Running Your Engine While You
Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
Engine Exhaust on page 2-36.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the climate control fan is at the highest
setting. One place this can happen is a
garage. Exhaust — with CO — can come in
easily. NEVER park in a garage with the
engine running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-38.

The thumbwheel for this feature is located next to the
exterior lamps control. SeeExterior Lamps on page 3-6.
D(Instrument Panel Lights):Turn the thumbwheel
up or down to brighten or dim the instrument panel lights
and the radio display. This will only work if the
headlamps or parking lamps are on.
To turn on the dome lamp, with the vehicle doors
closed, turn the thumbwheel all the way up.
Dome Lamp
The dome lamp will come on when you open a door.
You can also turn the dome lamp on by turning the
thumbwheel all the way up. In this position, the dome
lamp will remain on whether a door is opened or closed.
E(Dome Override):Press this button, located
below the exterior lamp control, to turn the dome lamp
off even when a door is opened. To return the lamp
to automatic operation, press the button again.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lamps
will not come on if the dome override button is
pressed in.
Battery Run-Down Protection
This feature shuts off the dome lamp if it is left on for
more than 20 minutes when the ignition is in LOCK. This

Accessory Power Outlets
Your vehicle may have an accessory power outlet.
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle may have two accessory power outlets
located on the lower part of the instrument panel below
the climate control system and there may be one
located on the rear of the center console. A small cap
must be pulled down to access an accessory power
outlet. When not using an outlet be sure to cover it with
the protective cap.

Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
Temperature Knob
The left knob on the control panel is used to adjust the
temperature of the air in the vehicle. Turn the knob
clockwise or counterclockwise to increase or decrease
the temperature.
Fan Knob
9
(Fan):The center knob on the control panel is
used to control the fan speed. Turn the knob clockwise
or counterclockwise to increase or decrease the
fan speed.
If the knob is set on “0” (zero), some outside air will still
enter the vehicle and will be directed according to
the position of the mode knob.
Mode Knob
The right knob on the control panel is used to direct the
airow inside your vehicle. Turn the knob to select
one of the following modes:
H(Vent):Select this mode to direct air to the
instrument panel outlets.
\(Bi-Level):Select this mode to direct approximately
half of the air to the instrument panel outlets, and the
remaining air to the oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):Select this mode to direct air to the oor
outlets. Recirculation does not work in this mode. Uplevel climate controls shown, base similar
3-12

Mode Buttons
@
(Recirculation):If your vehicle has air
conditioning, you will have the recirculation feature. This
mode recirculates air inside the cabin, and prevents
outside air from coming in the vehicle. It can be used to
prevent outside odors from entering your vehicle and
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on or off. An
indicator light on the button will come on to let you know
the recirculation mode is activated.
Recirculation is only available in the bi-level and vent
modes. If you push the recirculation button while
the system is in any other mode, the light on the button
will ash to indicate that recirculation is not available.
#(Air Conditioning):Your vehicle may have air
conditioning. Press this button to turn the air-conditioning
system on or off. An indicator light on the button will
come on to let you know the air conditioning is activated.
When the system is on, this setting cools and
dehumidies the air entering your vehicle.
The air conditioning will not function if the fan is
turned off.You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
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.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield and side windows. Use the
defog mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
For best results, clear all snow and ice from the
windshield before defrosting.
Turn the mode knob on the climate control panel
clockwise to select the defog or defrost modes.

{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger’s frontal air
bag could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger air bag risk group sit
in the right front passenger’s position (for
example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced.
Battery Warning Light
This light will come on
briey 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. Driving 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.
