2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air into
your vehicle until warmer air is available. The
system will start out blowing air at the oor but may
change modes automatically as the vehicle
warms up to maintain the chosen temperature
setting. The length of time needed to warm
the interior will depend on the outside temperature
and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to stabilize in
order for the system to regulate automatically. Then
adjust the temperature as necessary to nd your
comfort setting.Do not cover the solar sensor located in the center of
the instrument panel near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
After your vehicle is started, the display will show the
interior temperature settings and the outside
temperature.
If the AUTO position is selected on the fan or mode
control, the system will automatically control the
air conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator light
will be lit when the system is operating automatically,
even at near freezing outside temperatures. Press
the A/C button on the fan control to turn off the A/C.
For improved window clearing performance in defog
or defrost modes, the A/C compressor will run
automatically in damp cool conditions.

In order to prevent false temperature readings at
startup, the displayed temperature will not change until
the following occurs:
Vehicle speed is above 10 mph (16 kmh) for
5 minutes.
Vehicle speed is above 32 mph (51 kmh) for
2 and a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the 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.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield. Use the oor/defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.
W(Floor/Defog):Turning the control to this mode
directs approximately half of the air to the oor outlets
and the remaining air is directed to the side window
outlets and to the windshield. When you select
this mode, the system turns off recirculation and runs
the air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the oor/defog mode.
0(Defrost):Turning the control to this mode directs
most of the air to the windshield and the side window
outlets. In this mode, the system will automatically turn
off recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
Recirculation cannot be selected while in the defrost
mode. Do not drive the vehicle until all the windows
are clear.
For professional vehicles, air will be allowed to ow
through the rear outlets. For quicker defrost, press the
AUX button on the front climate control system so
that the light is not lit.

Rear Climate Control System
If your vehicle has a rear climate-control system, the
rear-seat passengers can use it to adjust the direction of
the airow, the fan speed and the temperature for the
rear-seating area. This system also works with the main
climate-control system in your vehicle.The control panel for this system is located on the back
of the center console.
If the AUX button located on the front climate control
panel is pressed, the rear climate control system will be
turned on. The rear system will operate in automatic
mode and the temperature settings selected for the front
climate control panel will also be selected for the rear
passengers.
If the rear passenger would like to adjust the rear
climate control system, they can select a different
temperature and a different mode or fan speed.
Whenever the rear passengers have adjusted settings
on the rear climate control system, the AUX light is lit on
the front climate control system. The driver can turn
off the auxiliary fan by pressing the AUX button.
When the front climate control system is turned off or
in defrost mode, the rear climate control system is
turned off. The rear system will turn back on once
another front mode is selected.

If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Set the climate controls to the highest heat setting
and fan speed and open the windows as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning does not come back on, you
can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get service
help right away.Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
message ENGINE OVERHEATED STOP ENGINE is
displayed, an overheat protection mode which alternates
ring groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and
engine performance. This operating mode allows your
vehicle to be driven to a safe place in an emergency.
Driving extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil and
reset the oil life system. SeeEngine Oil on
