SINGLE ZONE CLIMATE CONTROL
1.
Defrost:Distributes outside air through the windshield defroster
vents and de-mister vents. Can be used to clear the windshield of fog
and thin ice. The system will automatically provide outside air to reduce
window fogging. Press this button again to return to the previous air flow
selection.
2. A.
RRear defroster (if equipped):Press to activate/deactivate the
rear window defroster. Refer toRear window defrosterlater in this
chapter for more information. If your vehicle is equipped with both rear
defroster and heated mirrors, the same button will activate both.
2. B.
Heated mirrors (if equipped):Press to activate/deactivate.
This feature will remove ice and snow from the side view mirrors.
3.
Multifunction control:Press repeatedly to cycle through the
settings to choose:
•
:Distributes air through the windshield defroster vents, de-mister
vents, floor vents and rear seat floor vents. The system will
automatically provide outside air to reduce window fogging.
•
:Distributes air through the instrument panel vents.
•
:Distributes air through the instrument panel vents, floor vents,
rear seat floor vents and de-mister vents.
•
:Distributes air through the floor vents and rear seat floor vents.
4.A/C (if equipped):Press to activate/deactivate air conditioning. Use
with recirculated air to improve cooling performance and efficiency. A/C

5.Recirculated air (if equipped):Press to activate/deactivate air
recirculation in the vehicle. Recirculated air may reduce the amount of
time needed to cool down the interior of the vehicle and may also help
reduce undesired odors from reaching the interior of the vehicle.
Recirculated air engages automatically when MAX A/C is selected or can
be engaged manually in any airflow mode except
(defrost). When
the ignition switch is turned off and back on, the climate system will
return to the recirculated air mode only if the A/C button LED is
illuminated and the air distribution selection is either
(panel)
or
(panel/floor).
6.MAX A/C (if equipped):Distributes recirculated air through the
instrument panel vents to cool the vehicle. This re-cooling of the interior
air is more economical and efficient than normal A/C mode. Recirculated
air may also help reduce undesirable odors from entering the vehicle.
Press the MAX A/C button again for normal A/C operation.
7.Temperature control:Controls the temperature of the airflow in the
vehicle.
8.
Fan speed adjustment:Controls the volume of air circulated in
the vehicle.
9.
Power:Press to activate/deactivate the climate control system.
When the system is off, outside air is prevented from entering the
vehicle.
Operating tips
•To reduce fog build-up on the windshield during humid weather,
select
(defrost) or(floor/defrost). Temperature and/or fan
speed can also be increased to improve clearing.
•To reduce humidity build-up inside the vehicle: do not drive with the
system off or with recirculated air engaged and A/C off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out.”
•A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.

If you are driving during extreme high ambient temperatures and idling
for extended periods of time in gear, it is recommended to run the A/C
in the MAX A/C position, adjust the blower fan speed to the lowest
setting and put the vehicle’s transmission into the P (Park) position to
continue to receive cool air from your A/C system.
For maximum cooling performance (MAX A/C):
•Select MAX A/C.
(Panel) and(panel/floor) modes:
•Move the temperature control to the coolest setting.
•Select A/C and
(recirculated air). Use recirculated air with A/C
to provide colder airflow.
•Set the fan to the highest speed initially, then adjust to maintain
comfort.
To aid in side window defogging/demisting in cold weather:
1. Select
(panel/floor).
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan speed to the highest setting.
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
