Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't 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 weren't done correctly.

Your vehicle or exhaust system had been
modified 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 fixed immediately.
Running Your Engine While
You're Parked
It's 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
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the 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 ªBlizzardº in the Index.

2-73 Battery System Warning Light
When you turn the key to
RUN, this light will turn
on briefly to show that
the generator and battery
charging systems
are working.
If the light stays on, a chime will sound indicating that
the vehicle needs service. You should take your vehicle
to the dealer as soon as possible. To save the battery
until you get there, turn off all accessories and set the
climate control system to OFF.
Brake System Warning Light
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 is a brake problem.
Have your brake system inspected right away.

Comfort Controls
This section describes how to operate your climate
control system. With this system, you can control the
heating, cooling and ventilation in your vehicle.
Your vehicle also has a flow
-through ventilation system
described later in this section.
Electronic Touch Climate Control
Fan Lever
The FAN lever is used to select the speed of the fan.
Moving the lever between LOW and HIGH will
decrease or increase the fan speed. The fan will be
off when the system is off.Temperature Lever
This lever is used to adjust the temperature of the air
coming through the system. Move the TEMPERATURE
lever between COOL and WARM to change the
temperature of the air coming through your outlets.
Mode Controls
The buttons on your system allow you to choose settings
to deliver air through the floor ducts, instrument panel
outlets or windshield outlets.
RECIRC (Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to cool the interior of the
vehicle quickly, or limit the amount of outside air
entering your vehicle. To turn off RECIRC, press the
button again. If you select FRONT defrost or BLEND
while RECIRC is selected, the system will automatically
turn off RECIRC to prevent fogging. If you select
RECIRC while in FRONT defrost, the RECIRC light
will flash three times to let you know this is not allowed.

3-4 Dual Automatic ComforTemp
Climate Control (If Equipped)
TEMP (Temperature): To manually adjust the
temperature inside the vehicle, push the TEMP arrow.
Push the TEMP up arrow for warmer temperature
settings and the TEMP down arrow for cooler
temperature settings. The setting will be shown in the
display. The display will then return to the outside
temperature after a few seconds.
FAN: Pressing the FAN button will display and
hold the current fan speed while in manual mode.If you want the fan to run at a lower speed, push the
down arrow on the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the up arrow on the FAN button.
AIR FLOW: Pressing the AIR FLOW button will
display and hold the current setting while in manual
mode. Use the up and down arrows on the AIR FLOW
button to cycle through the available modes.

WINDSHIELD
-FLOOR: This setting directs
most of the airflow to the front windshield defroster
with some airflow to the side window defrosters and
floor ducts.

MID: This setting directs airflow through the
instrument panel outlets.

MID
-FLOOR: This setting directs airflow through
both the instrument panel outlets and the floor ducts.
There is also a small amount of air directed to the
front defroster and the side window defrosters.

FLOOR: This setting directs most of the airflow to
the floor ducts with some airflow directed to the side
window defrosters. There is also a small amount of
airflow directed to the front defroster.

3-6 Passenger Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
ComforTemp system, the front seat passenger can
control the air temperature in his or her seating area. The
control is located on the passenger's door armrest.The temperature can be set up to 5
F (3
C) cooler
or warmer than the primary setting. To activate the
passenger control, press the button with the red arrow
to increase temperature. Each time you press the button, a
red indicator light will come on. To decrease temperature,
press the button with the blue arrow. Each time you press
the button a blue indicator light will come on.
If the passenger control has been turned on, it can be
turned off by pressing the OFF button on the main
system once. (Pressing the OFF button a second time
will turn off the main system.)
Automatic Operation
Press the AUTO button when you want the system to
automatically maintain a selected temperature inside of
your vehicle. When the system is set for automatic
operation, air will come from the floor ducts, instrument
panel outlets or windshield outlets depending on the
temperature inside the vehicle, the outside temperature
and sun load. Fan speed and use of air conditioning and
recirculation will vary as needed.

3-7
Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your temperature setting. The system may
supply cooler air to the side of the vehicle toward the
sun. Be careful not to put anything over the sensor on
top of the dash.
The display will show fan speed, temperature level
setting and airflow direction for a few seconds whenever
AUTO is selected, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving. During stops, the
display shows the previous temperature for best
accuracy and system control.
To find your preferred temperature setting, start with the
system in AUTO mode and the TEMP button adjusted
to 75
F (24
C), give the vehicle about 20 minutes to
stabilize, and adjust your temperature setting if
necessary, by using the TEMP button. The display will
show the temperature setting for a few seconds and then
it will display the outside temperature. If you want to
see your current automatic fan speed, airflow direction
and temperature setting, press the AUTO button.In cold weather, the system will delay turning on the fan,
to avoid blowing cold air. During this delay the system
will be in FRONT defrost mode and the light in the button
will come on and stay on as long as the display is showing
the current mode, set TEMP and FAN speed. This light
will go off when the display returns to the outside
temperature. The length of the delay depends on the
engine coolant temperature and the outside temperature.
Pushing the FAN, AIR FLOW or FRONT buttons will
override this delay, turn off the AUTO setting and return
the system to manual operation.
Personal Choice Comfort Controls
(If Equipped)
This feature enables up to two drivers to store and recall
comfort control settings for the temperature, fan speed
and the direction of the airflow.
The memory buttons (1 or 2) for this feature are located
on the driver's door panel and correspond to the
numbers (1 or 2) found on the back of each keyless
entry transmitter.
To recall comfort settings, press the unlock button on the
remote keyless entry transmitter and put the ignition in
ACCESSORY or RUN. The climate control setting last
chosen by the identified driver (1 or 2) will be recalled.
