Display Function
Each time the temperature, mode, or fan control buttons are pressed, the climate control display shows that function along with the inside temperature setting. The outside temperature is displayed on the instrument panel cluster.
(On/Off): Press to turn the climate
control system on or off.
While the system is off, outside air still enters through the floor outlets, but the air delivery mode can be adjusted.
The climate control system will also turn on if either the fan control, defrost, AUTO, or air conditioning buttons are pressed.
Automatic Operation
AUTO (Automatic): The system automatically controls the inside temperature, the air delivery, and the fan speed.
To use automatic mode:
1. Press the AUTO button.
When AUTO is selected, the current temperature(s) selected and AUTO is shown on the display. The current air delivery mode and fan speed also appear for approximately five seconds.
When AUTO is selected, the air conditioning and air inlet are automatically controlled.
The air conditioning runs when the outside temperature is over 4°C (40°F). The system is automatically set to outside air, unless it is hot outside and then the air inlet changes to recirculation mode to help quickly cool the vehicle.
The recirculation indicator light will come on.
2. Set the temperature for the driver and passenger.
To find a comfortable setting, start with a 22°C (73°F) temperature setting and allow about 20 minutes for the system to regulate. Use the driver side or passenger side temperature buttons to adjust the temperature setting as necessary. The system will remain at the selected setting.
Choosing the warmest or coolest temperatures does not cause the vehicle to heat or cool more quickly.
To avoid blowing cold air in cold weather, the system delays turning on the fan until warm air is available. Press the fan control to override this delay and select the fan speed.
Temperature Control
The driver and passenger side temperature buttons are used to adjust the temperature of the air coming through the system. The temperature can be adjusted even if the system is turned off since outside air still enters the vehicle, unless the recirculation mode is selected.
See “Recirculation” later in this section.
Driver Side Temperature
Control: Press the + or − buttons to increase or decrease the driver side temperature. The driver side temperature display will show the temperature setting.
Passenger Side Temperature
Control: Press the + or − buttons to increase or decrease the passenger side temperature.
The passenger side display will show the temperature setting.
PASS (Passenger): Press to set the passenger temperature to match the driver temperature setting. The PASS indicator will turn off. When the passenger temperature setting is different than the driver setting, the PASS indicator comes on.
Manual Operation
The air delivery mode or fan speed can be manually adjusted.
(Fan Control): Press to increase
or decrease the fan speed.
Pressing 
while in automatic control
places the fan speed under manual control.
The air delivery mode remains in automatic control. The fan setting still displays, but the word AUTO no longer displays, and the AUTO button indicator light turns off.
(Air Delivery Mode Control): Press
to change the direction of the airflow in the vehicle.
Repeatedly press 
until the
desired mode appears on the display. Pressing a mode button while the system is
off changes the air delivery mode without turning the system on. Press a mode button
while in automatic control to place the system into manual control.
The air delivery mode setting still displays, but the word AUTO no longer displays, and the AUTO button indicator light turns off.
(Vent): Air is directed to the instrument
panel outlets.
(Bi-Level): Air is divided between
the instrument panel and floor outlets. Some air is directed towards the windshield
and side window outlets. Cooler air is directed to the upper outlets and warmer
air to the floor outlets.
(Floor): Air is directed to the
floor outlets, with some of the air directed to the windshield, side window, and
second row floor outlets. In this mode, the system uses outside air.
(Defog): This mode clears the windows
of fog or moisture. Air is directed to the windshield, floor outlets, and side window
vents.
When this mode is selected, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is less than 4°C (40°F). Do not drive the vehicle until all the windows are clear.
(Defrost): Press to turn the defrost
on or off. This mode quickly clears the windshield of fog or frost.
Air is directed to the windshield, side window, and floor vents.
In this mode, outside air is pulled inside the vehicle.
The air conditioning system runs automatically in this setting, unless the outside temperature is less than 4°C (40°F).
Do not drive the vehicle until all the windows are clear.
While in defrost mode, if the PASS button is pressed, the PASS button indicator flashes three times to show that the passenger climate control system cannot be activated. If the passenger temperature buttons are adjusted while in defrost mode, the driver temperature indicator will change.
The passenger temperature will not be displayed.
When returning to bi-level, vent, or floor mode, the previous temperature settings displays in place of any change made while in defrost mode.
Air Conditioning
(Air Conditioning): Press to turn
the air conditioning (A/C) on and off. An indicator light comes on when A/C is on.
The A/C does not work when the outside temperature is below 4°C (40°F). If
is pressed the indicator flashes three
times and turns off to show that the A/C mode is not available. If the A/C is on
and the outside temperature drops below a temperature which is too cool for air
conditioning to be effective, the A/C indicator turns off to show that the A/C mode
has been canceled.
On hot days, open the windows briefly to let hot inside air escape.
This helps reduce the time it takes for the interior of the vehicle to cool down.
The air conditioning system removes moisture from the air, so water might drip under the vehicle while idling or after turning off the engine. This is normal.
(Recirculation): Press to turn
the recirculation mode on or off.
An indicator light comes on when recirculation is on. When the engine is turned off, the recirculation mode automatically turns off and must be re-selected when the engine is turned on again.
This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to prevent outside air and odors from entering the vehicle.
The recirculation mode cannot be used with floor, defog, or defrosting modes. If recirculation is selected in these modes, the indicator flashes three times and turns off.
The air conditioning compressor also comes on when this mode is activated. While in recirculation mode the windows can fog when the weather is cold and damp.
To clear the fog, select either the defog or defrost mode and increase the fan speed.
REAR: Press to turn the rear heating and air conditioning on or off. See Rear Climate Control System (Rear Climate Control Only) or Rear Climate Control System (Rear Climate with Rear Seat Audio) .
Rear Window Defogger
The rear window defogger uses a warming grid to remove fog from the rear window.
(Rear Window Defogger):
Press to turn the rear window defogger on or off. The rear window defogger stays on for about 10 minutes, before turning off.
The defogger also turns off when the engine is turned off. Do not drive the vehicle until all the windows are clear.
For vehicles with heated outside rearview mirrors, fog or frost is cleared from the surface of the mirror when the rear window defog button is pressed.
Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty.
Sensors
The solar sensor, located in the defrost grille in the middle of the instrument panel, monitors the solar heat. Do not cover the solar sensor or the system will not work properly.
The interior temperature sensor located on the instrument panel to the right of the steering column, measures the temperature of the air inside the vehicle.
There is also an exterior temperature sensor located behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false reading in the displayed temperature.
The climate control system uses the information from these sensors to maintain comfort settings by adjusting the temperature, fan speed, and air delivery mode.
The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures.
