Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, defrosting, and ventilation for the vehicle.
Automatic Operation
The climate control system automatically adjusts
the air temperature, air delivery mode, fan
speed, and air conditioning for best comfort in the
vehicle.To activate the automatic system:
AUTO (Automatic Mode):
1. Turn the fan and mode controls to the AUTO
position. This also sets the recirculation mode
to automatic operation on the display.
2. Press the up or down arrows to adjust the
temperature to a comfortable setting between
70°F (21°C) and 80°F (27°C).
3. Allow the system time to stabilize. This might
take several minutes in very hot or cold
weather. Then adjust the temperature, as
needed for best comfort.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available.
The automatic system starts out blowing air at
the oor, but changes modes automatically as
the vehicle warms up to maintain the chosen
temperature setting.
The length of time needed to warm the interior
depends on the outside temperature and
the amount of time that has passed since the
vehicle was last driven.

?(Recirculation):This mode recirculates air
inside the vehicle and keeps outside air from
coming into the vehicle. It can be used to help cool
the vehicle more quickly or to prevent odors
from entering the vehicle.
Recirculation is not available in the defrost mode.
It is also cancelled when oor or defog mode
is selected. In some conditions using recirculation
for long periods of time can cause the air inside
the vehicle to become too dry or stuffy. To prevent
this from happening, after the air in the vehicle
has cooled, select auto air inlet or outside air.
:(Outside Air):This mode pulls fresh air from
outside the vehicle. Outside air is always
selected in defrost mode to prevent fogging.
Air Conditioning
#
(Air Conditioning):Press this button to turn
the air conditioning on or off, and override the
automatic system. When selecting the AUTO fan
or AUTO mode, the air conditioning compressor
comes on automatically, as necessary.The air conditioning system removes moisture
from the air, so you might notice water dripping
underneath the vehicle while idling or after turning
off the engine. This is normal.
Sensors
There is a solar sensor located on top of the
instrument panel, near the windshield.
192

There is also an interior temperature sensor
located below the climate control system next to
the steering wheel.
There is also an ambient sensor located behind
the grille in front of the vehicle.
These sensors help the climate control system
automatically control the temperature setting. The
system can 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.
Do not cover any of the sensors or the climate
control system might not work properly.
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 the windshield.
W(Floor/Defog):Use this mode to clear the
windows of fog and warm the passengers.
The system turns off recirculation and runs the air
conditioning compressor unless the outside
temperature is at or below freezing. If recirculation
mode is selected while using the defog mode,
the system recirculates air initially but returns to
the fresh air mode after 10 minutes.
0(Defrost):Use this mode to remove fog or
frost from the windshield more quickly. When
selected, the system turns off recirculation
and runs the air conditioning compressor, unless
the outside temperature is at or below freezing.
Do not drive the vehicle until all the windows are
clear.

Rear Air Conditioning System
If your vehicle has the rear air conditioning system
it has two fan speed selectors. One fan speed
selector is located in the front overhead console
and the other is located in the headliner above the
second row seats. The rear air conditioning
system is designed to provide cooled air only.
To operate the rear system using the front control,
just turn the knob to the fan position you want.
To use the rear control, rst turn the front control
to AUX, then the rear control can be used to
increase and decrease the airow.
Passenger Compartment Air Filter
The passenger compartment air lter helps remove
dust and pollen from the air entering the vehicle.
Like the vehicle’s engine air cleaner/lter, it
needs to be changed periodically. For how often
to change the passenger compartment air
lter, seeScheduled Maintenance on page 471.
The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 356
for more information on location.
