3-8 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the heater or the air
conditioning fan is running.
The front outlets are located in the center and at each
side of the instrument panel. You can adjust the
direction of airflow by moving the center control levers
or you can stop the airflow by moving the control dial
located on each outlet downward.Rear Ventilation
The direction and quantity of airflow for the rear seats
can also be adjusted at the back of the console. Heater
outlets are located under the front seat to warm the feet
of rear passengers.
Move the fan lever to adjust the blower speed from LO
to HI. Adjust the knob to direct the air flow. To reduce
airflow to the rear outlets, slide the fan lever all the way
to the left. Turning the knob to OFF will completely
stop airflow, no matter where the fan blower control
is set.

3-10 HVAC Steering Wheel Controls
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº in
the Index.
TEMP: Press the up arrow on the control to increase
the temperature and the down arrow to

the fan speed and the down arrow to decrease fan speed.
Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. These settings include the set
temperatures for driver and passenger, air conditioning,
mode and fan speed. (This feature does not recall
recirculation or defrost modes.) This feature allows two
different drivers to store and recall their own climate
control settings. The settings recalled by the climate
control system are determined by which Remote
Keyless Entry (RKE) transmitter (ª1º or ª2º) was used
to enter the vehicle. The number on the back of the
RKE transmitter corresponds to driver 1 or to driver 2.
After any button is pressed on the RKE transmitter or
the key is placed in the ignition, the climate control
settings will automatically adjust to where they were last
set. The settings can also be changed by briefly pressing
buttons 1 or 2 located on the driver's door.
