Running Your Engine While You're
Parked (Automatic Transmission)
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.
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works
like a standard axle most of the time, but when one
of the rear wheels has no traction and the other does,
this feature will allow the wheel with traction to move
the vehicle.

3-4 Automatic Electronic Dual Climate Control
System (Option)
Your vehicle may be equipped with an automatic
electronic dual climate control system. This system can
automatically adjust and control temperature output, fan
speed, air delivery mode, air conditioning operation and
air intake. You can use the AUTO (automatic) setting or
override the automatic operation with manual control
settings. The set temperature will be remembered each
time you turn the ignition off and restart in the same
settings. You can use the memory option to recall your
settings. SeeªMemoryº in the Index.Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the E/M button (English/Metric)
on the Driver Information Center (DIC). When you
start the vehicle, the display will show the current fan
speed, air delivery mode and the driver
-set temperature
for approximately five seconds and then show the
outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display unless you
are in full cold 60
F (16
C) or full hot 90
F (32
C),
then the word AUTO will not display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display. If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.

3-7
Manual Settings
With the automatic electronic dual climate control
system, there are several manual settings you can use
to control the system and override the AUTO operation.
You can program the fan speed, air delivery mode, air
intake mode and control the air conditioning operation
using these settings. The system will still determine the
temperature output level based on the driver
-set
temperature and the passenger temperature offset.
(Fan Speed): Press the button with the fan symbol
on it to manually lock in the current fan speed and to
stop the automatic fan speed control. Pressing the
arrows will delete AUTO from the digital display.
The fan graphics with the fan speed bars will be shown.
To increase the fan speed so that more air flows into
the vehicle, press the up arrow on the fan switch.
To decrease the fan speed and airflow, press the down
arrow. The AUTO button must be pressed to return
to the automatic fan control.MODE: Press the MODE button to manually lock in
the current air delivery setting and to stop the automatic
mode control. Pressing the MODE button will delete
AUTO from the digital display and the mode graphics
will be shown. To change the setting, press the MODE
button again. The AUTO button must be pressed to
return to the automatic mode selection.
(Vent): This setting directs most of the air through
the instrument panel outlets and a very small amount to
the lower outlets.
(Bi-Level): This setting directs air into the vehicle
in two ways. Cooler air is directed toward your upper
body through the instrument panel outlets, while warmer
air is directed through the lower outlets.
(Floor): This setting directs most of the air to the
floor area and some of it toward the windshield and side
window vents.
(Defog): This setting divides the air between
the windshield and lower outlets and a small amount
toward the side window vents. This is useful when fog
appears on the windshield or side glass due to rain or
snowy conditions.

3-8
Function Buttons
These buttons control the climate control ON/OFF,
air intake, front defrost, rear defrost and the air
conditioning operation.
OFF: Press the OFF button to turn off the climate
control system. This is the only setting that fully
shuts off the fan. The digital display will show only the
outside temperature. You can still adjust the driver set
temperature, the passenger temperature offset and the
air intake mode while in OFF.
A/C (Air Conditioning): This button turns
the air conditioning compressor off or on under most
conditions. The light on the A/C button will come on
when the compressor is operating in either the automatic
or manual mode. The air conditioning does not operate
at temperatures below approximately 35
F to 40
F
(2
C to 4
C). The light on the A/C button will flash if
pressed when air conditioning is not available. The air
conditioning cools and dehumidifies the air coming into
the vehicle. The air conditioning cannot be turned off in
defrost and defog, as it helps to remove moisture from
the vehicle. It also helps to keep the windows clear.If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures.
(Outside Air): Press this button to provide outside
air. The light on this air intake button will come on to
show when it is operating. When in the AUTO mode,
the system automatically selects outside air instead of
recirculate, as required, to control the temperature in the
vehicle. By pressing outside air, the system will lock
into the outside air mode. Any adjustment to the air
intake must then be made manually. Outside air should
be used when trying to defrost or defog windows to help
reduce moisture inside of the vehicle.

3-10 Sensors
The automatic electronic dual climate control system
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of
the instrument panel.
The sensor monitors the sun's solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.
Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor is
used for the outside air temperature readings shown on the
digital display for the automatic climate control system.If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature
display is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor
to receive information, so if you block or cover it,
the system will not function properly.

3-11 Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning
to work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature control knob (on a
manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum cooling is required.
When the air conditioning is on, you may sometimes
notice slight changes in the vehicle's engine performance
and power. This is normal. The system is designed to
help fuel economy while maintaining the desired
cooling level.
The air conditioning removes moisture from the air,
so you may notice water dripping from under the
vehicle when it is idling or after it has been turned off.
This is normal.
Heating
The heater works best if you keep the windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob
(on a manual climate control system) is all the way in
the red area. These settings will be selected by the
automatic electronic dual climate control system if
operating in AUTO when maximum heating is required.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
The bi
-level setting will direct cooler airflow to your
upper body and warmer air to the floor area.
If you have the optional engine coolant heater and use it
during cold weather 0
F (
-18
C) or lower, the heating
system will provide heat more quickly because the
coolant is already warmed. See ªEngine Coolant Heaterº
in the Index.
