positions, telescopic steering wheel (if equipped), radio
presets, tone, volume, playback mode (AM/FM, tape
or CD), last displayed station, compact disc position and
tape direction and the last climate control setting.

2-8
The MEMORY buttons are located on the driver's door,
above the power mirror controls. The MEMORY
buttons can store and recall settings for up to three
drivers. Use button ª1º to store the settings for the
first driver, button ª2º for a second driver or press
buttons 1 and 2 at the same time for a third driver.
To store your memory settings:
1. Adjust your settings for the driver's seat position,
outside rearview mirror positions, and telescopic
steering wheel (if equipped).
2. Press and hold a MEMORY button. The light above
the MEMORY button will glow steady for one
second and then flash once when the settings are
complete. Then the light will go off.
3. Set the climate control temperature, fan speed and
mode settings, radio presets, tone, volume, playback
mode (AM/FM, tape or CD), tape direction and
compact disc position.
Your memory settings are now programmed. Any
changes that are made to the audio system and climate
controls while driving will be automatically stored when
the ignition key is turned off.When first entering your vehicle, after pressing the
unlock button on your remote keyless entry transmitter
or a MEMORY button, a recall of your settings will
occur when the door is closed and the ignition key is in
the ignition switch. As the memory settings are recalled,
the light above the button will flash until the correct
settings are achieved, then glow for five seconds
when complete.
A memory recall can be stopped by pressing any
memory seat, mirror or steering column position button.
When your remote keyless entry transmitter has been
programmed to driver 1, 2 or 3, and you insert the key into
the ignition, memory will also occur. Drivers 1, 2 and
3 correspond to the order in which your remote keyless
entry transmitters were programmed. See ªFob Trainingº
in the Index for more information.
Memory recall will not work if the vehicle is moving.
Memory recall will be temporarily interrupted during
engine crank.

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 switch 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. See ªMemoryº 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.
Driver Set Temperature Knob
The DRIVER knob changes the temperature on the
driver's and passenger's side of the vehicle. Turn the
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature.
Whenever you turn this knob, the temperature will be
displayed for approximately five seconds along with the
current fan speed and air delivery mode.

3-6
As the interior of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI
-LEVEL).
A Typical Hot Weather Example:
The vehicle has been parked outside all day in hot
weather above 80
F (27
C) and you have set the driver
temperature at 73
F (23
C) and have selected the
AUTO mode. The system will automatically adjust the
temperature output to maximum cooling. The fan will
start at a low speed momentarily to push the hot air to
the floor of the vehicle and then go to a higher fan speed
with cold airflow out of the instrument panel outlets. A
small amount of airflow will continue through the lower
ducts to cool the floor area.The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to your comfort set temperature,
the fan speed will decrease and the temperature output
may become warmer. The air intake may shift from
recirculation to outside air mode. If the interior
continues to cool due to a decrease in the amount of heat
the vehicle is absorbing from the sun or a decrease in the
outside temperature, the system could switch to other air
delivery modes (typically BI
-LEVEL or DEFOG).
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.

3-7
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.
UPPER: 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.
LOWER: 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.
Function Buttons
These buttons control 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.

3-9
Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the DEFOG or DEFROST mode and
increase the fan speed. To avoid re
-fogging of the
windows, operate the system in the OUTSIDE
AIR mode.
FRONT: Press the FRONT defrost button to
quickly remove fog or frost from the windshield. This
setting directs most of the airflow to the windshield and
a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in OUTSIDE AIR.
If the system is in FRONT defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in OUTSIDE AIR.
See ªRear Window Defoggerº later in this section for
more information.
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.

3-10
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.
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 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.

3-11 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 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.
Defogging and Defrosting
To rapidly defrost the windshield, the FRONT defrost
mode (automatic electronic dual climate control system)
or defrost mode (manual control system) should be used
and the fan speed should be adjusted to the highest
speed. With the manual control system, turn the
temperature knob all the way to the red area.
To keep the windshield clear and provide heated air to
the floor area of the vehicle, use the DEFOG setting.
Your vehicle is equipped with side window defogger
vents located near the side rearview mirrors.
Rear Window Defogger
REAR: This button turns the rear defogger and the
heated outside mirrors on. The light on the button will
come on when operating. The system automatically
shuts off after approximately 15 minutes. If further
defogging is desired, press the button again and it will
operate for about seven and a half more minutes.
The rear window defogger operates only when the
engine is running.
