Climate Controls 8-5
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.
O(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.

outside air still enters the vehicle,
unless the recirculation mode is
selected. See“Recirculation” later
in this section.
Driver Side Temperature

8-8 Climate Controls
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)
on page 8‑10 orRear Climate
Control System (Rear Climate with
Rear Seat Audio) on page 8‑11.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(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.

WARNING (Continued)
carbon monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about
5 cm (2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan
speed to the highest setting.
See“Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑22.
Run the engine for short periods
only as needed to keep warm, but
be careful. To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
