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 to cancel automatic fan
speed operation. Rotate the
thumbwheel 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
display will remain the same and air will be cooled based on the
selected temperature. To exit, press AUTOMATIC or any other
override controls. MAX A/C is noisier than NORM 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.
²NORM A/C-Uses outside air to cool the vehicle. The temperature
display will remain the same and air will be cooled based on the
selected temperature. It is quieter than MAX A/C but not as
economical. Fan speed will remain automatic. Airflow is from the
instrument panel registers.
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.
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, use this mode to prevent undesirable odors from
entering the vehicle. For short periods of time only, use this mode to
prevent undesirable odors from entering the vehicle.

Displaying outside temperature
Press OUTSIDE TEMP to display
the outside air temperature. It will
be displayed until OUTSIDE TEMP
is pressed again.
If the selected temperature is changed while the outside temperature is
displayed, the new temperature will be displayed for four seconds after it
is changed, then the outside temperature will return to the window.
If a manual override function is selected while the outside temperature is
displayed, the new function will be displayed for four seconds after it is
changed, then the outside temperature will return to the window along
with the override selection.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be obtained when the vehicle is not
moving. The readings that you get may not agree with temperatures
given on the radio due to differences in vehicle and station locations.
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.

Press the control to turn the mirror
on or off.
The mirror will automatically return
to the normal state whenever the
vehicle is placed in R (Reverse)
(when the mirror is on) to ensure a
bright clear view when backing up.
ELECTRONIC COMPASS (IF EQUIPPED)
The compass reading will remain accurate during most driving
conditions. Unknown to the driver, the compass is continuously
recalibrating due to magnetic fields and subtle, slow changes in vehicle
magnetics which can occur over the life of the vehicle.
The compass reading will remain fixed when significant levels are
experienced (such as steel bridges). The compass will return to normal
operation upon leaving the magnetized area.
If highly magnetized items (such as magnetic mount antennas) are
placed very near the compass the display will change to ªCº for 15
seconds, then display all segments until the magnetized item is removed.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer toCompass zone adjustment.

Compass zone adjustment
1. Determine which compass zone
you are in by referring to the zone
map.
2. With the compass display turned
on, press and hold the COMP side of
the control until the zone selection
number appears in the mirror
display window.
3. Release the COMP side of the
control, then press it down again.
4. Continue to press until your zone
number is shown in the mirror
display, then release.
5. The display will show all segments, then return to normal compass
mode within ten seconds.
Compass calibration adjustment
