Turning the EATC off
Press OFF.
Automatic operation
Press AUTOMATIC and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC system will either heat or cool to achieve the selected
temperature. The system will automatically determine fan speed, airflow
location and if fresh outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed thumbwheel is turned or the
steering wheel fan speed control is pressed.
When in AUTOMATIC and weather conditions require heat, air will be
sent to the floor. However, if the engine is not warm enough to provide
heat, the fan will be at a low speed and the air will be directed to the
windshield. In 3
1¤2minutes or less, the fan speed will start to increase
and the airflow location will change to the floor area.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations and the fan control
allows you to adjust fan speed as necessary.
Temperature selection
The display window indicates the
selected temperature, function
(AUTO or one of the override
controls) and manual control of fan
speed (
) if automatic fan speed is not desired.

To control the temperature, select
any temperature between 18ÉC
(65ÉF) and 29ÉC (85ÉF) by pressing
the blue (cooler) or red (warmer)
buttons.
For continuous maximum cooling, push the blue button until 16ÉC
(60ÉF) is shown in the display window. The EATC will continue
maximum cooling (disregarding the displayed temperature) until a
warmer temperature is selected by pressing the red button.
For continuous maximum heating, push the red button until 32ÉC (90ÉF)
is shown in the display window. The EATC will continue maximum
heating (disregarding the displayed temperature) until a cooler
temperature is selected by pressing the blue button.
Temperature conversion
Press MAX A/C and DEFat the
same time (for one second) to
switch between Fahrenheit and
Celsius.
If your vehicle has an English/Metric (E/M) control, this control will also
change the temperature display.
Fan speed ()
When AUTOMATIC is pressed, fan
speed is adjusted automatically for
existing conditions. You can override
fan speed at any time. To control
fan speed manually, use the
thumbwheel or steering wheel
control to cancel automatic fan
speed operation.

²Rotate the thumbwheel up for higher fan speed or down for lower fan
speed.
²Press the steering wheel fan speed control up for higher fan speed or
down for lower fan speed.
The display will show
to indicate
manual fan operation.
To return to automatic fan operation, press AUTOMATIC.
Manual override controls
The override controls are located at
the bottom of the EATC and allow
you to determine where airflow is
directed. To return to full automatic
control, press AUTOMATIC.
The air conditioning compressor will operate in all modes except FLOOR
and VENT. It will also operate only when required when AUTOMATIC
has been selected. However, the air conditioning will only function if the
outside temperature is about 10ÉC (50ÉF) or above.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
Under normal conditions, your vehicle's climate control system should be
left in any position other than MAX A/C or OFF when the vehicle is
parked. This allows the vehicle to ªbreatheº through the outside air inlet
duct.
²MAX A/C-Uses recirculated air to cool the vehicle. The temperature
will display 16ÉC (60ÉF). To exit, press AUTOMATIC or any other
override controls. MAX A/C is noisier than normal A/C but more
economical and will cool the inside of the vehicle faster. Airflow is
from the instrument panel registers. This mode can also be used to
prevent undesirable odors from entering the vehicle.
²VENT-Distributes outside air through the instrument panel registers.
However, the air cannot be cooled below the outside temperature
because the air conditioning does not operate in this mode.

²PNL²FLR-Distributes outside air through the instrument panel
registers and the floor ducts. Heating and air conditioning capabilities
are provided in this mode. The air will be heated or cooled based on
the temperature selection. For added customer comfort, the air
distributed through the floor ducts will be slightly warmer than the air
sent to the instrument panel registers.
²FLOOR-Allows for maximum heating by distributing outside air
through the floor ducts. However, the air cannot be cooled below the
outside temperature because the air conditioning does not operate in
this mode.
²FLR²DEF-Distributes outside air through the windshield defroster
ducts and the floor ducts. Heating and air conditioning capabilities are
provided in this mode. The air will be heated or cooled based on the
temperature selection. For added customer comfort, the air
distributed through the floor ducts will be slightly warmer than the air
sent to the windshield defroster ducts. If the temperature is about
10ÉC (50ÉF) or higher, the air conditioner will automatically
dehumidify the air to prevent fogging.
²DEF
-Distributes outside air through the windshield defroster
ducts. It can be used to clear ice or fog from the windshield. If the
outside air temperature is about 10ÉC (50ÉF) or higher, the air
conditioner will automatically dehumidify the air to prevent fogging.
²OFF-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.

Operating tips
²In humid weather, select DEFbefore driving. This will prevent
your windshield from fogging. After a few minutes, select any desired
position.
²To prevent humidity buildup inside the vehicle, don't drive with the
climate control system in the OFF position.
²Don't put objects under the front seat that will interfere with the
airflow to the back seats.
²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield).
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate the air
conditioner as you would normally.
²When placing objects on top of your instrument panel, be careful to
not place them over the defroster outlets. These objects can block
airflow and reduce your ability to see through your windshield. Also,
avoid placing small objects on top of your instrument panel. These
objects can fall down into the defroster outlets and block airflow and
possibly damage your climate control system.

Refer to theDrivingchapter for
more information.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the reverse gear is selected.
The RSS will assist the driver in detecting certain objects while the
vehicle slowly moves in reverse at speeds less than 8 km/h (3 mph). The
RSS is not effective at speeds greater than 8 km/h (3 mph) and may not
detect certain angular or moving objects. The weather may also affect
the function of RSS. RSS may have reduced performance in the rain or
snow.
