system on and off. When the
system is off, it prevents outside
air from entering the vehicle.
B
Air distribution control: Press
to switch air flow from the
windshield, instrument panel, or
footwell vents on or off. You can
distribute air through any
combination of these vents.
C
Note:
At least one of these
buttons illuminates on when the
system is on. A/C:
Press to switch the air
conditioning on or off. Use A/C
with recirculated air to improve
cooling performance and
efficiency.
D
MAX A/C:
Press for maximum
cooling. Recirculated air flows
through the instrument panel
vents, air conditioning turns on
and the fan adjusts to the
highest speed.
E
Temperature control:
Adjusts
the temperature of the air
circulated in your vehicle.

Power: Press to switch the
system on and off. When the
system is off, it prevents outside
air from entering the vehicle.
A
Heated seats:
Press to switch
the heated seats on and off.
B
Driver temperature control:
Adjusts the temperature setting
on the driver side. This control
also adjusts the passenger side
temperature when you switch
off dual zone mode.
C
Heated rear window:
Press to
switch the heated rear window
on and off. See
Heated
Windows and Mirrors (page
141).
D
MAX Defrost:
Press to switch
on defrost. The driver and
passenger settings set to HI, air
flows through the windshield
vents, and the fan adjusts to the
highest speed. You can also use
this setting to defog and clear
the windshield of a thin covering
of ice. The heated rear window
also turns on when you select
maximum defrost.
E
Note:
To prevent window
fogging, you cannot select
recirculated air when maximum
defrost is on.
Air distribution control: Press
to switch air flow from the
windshield, instrument panel, or
footwell vents on or off. You can
distribute air through any
combination of these vents.
F
A/C:
Press to switch the air
conditioning on or off. Use A/C
with recirculated air to improve
cooling performance and
efficiency.
G Note:
In certain conditions (for
example, maximum defrost), the
air conditioning compressor may
continue to operate even though
you switch off the air
conditioning.
MAX A/C:
Press for maximum
cooling. The driver and
passenger settings set to LO,
recirculated air flows through the
instrument panel vents, air
conditioning turns on and the fan
adjusts to the highest speed.
H
Passenger temperature
control:
Adjusts the
temperature setting on the
passenger side.
I
DUAL:

temperature control for the
passenger side of the vehicle.
When dual zone is off, passenger
temperature settings remain the
same as the driver settings.
J
Recirculated air:
Press to
switch between outside air and
recirculated air. The air currently
in the passenger compartment
recirculates. This may reduce the
time needed to cool the interior
(when used with A/C) and
reduce unwanted odors from
entering your vehicle.
K
Note:
Recirculated air may turn
off (or prevent you from
switching on) in all air flow
modes except MAX A/C to
reduce the risk of fogging.
Recirculation may also turn on
and off in Panel or Panel/Floor
air flow modes during hot
weather in order to improve
cooling efficiency.

HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Note: Prolonged use of recirculated air may
cause the windows to fog up.
Note: You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting.
Note: To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.
Note: Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats. Note:
Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.
Manual Climate Control
Note: To reduce fogging of the windshield
during humid weather, adjust the air
distribution control to the windshield air
vents position.
Automatic Climate Control
Note: Adjusting the settings when your
vehicle interior is extremely hot or cold is
not necessary. The system automatically
adjusts to heat or cool the interior to your
selected temperature as quickly as possible.
For the system to function efficiently, the
instrument panel and side air vents should
be fully open.
Note: If you select
AUTO during cold
temperatures, the system directs airflow to
the windshield and side window vents. In
addition, the fan may run at a slower speed
until the engine warms up.
Note: If you select
AUTO during hot
temperatures and the inside of the vehicle
is hot, the system automatically uses
recirculated air to maximize interior cooling.
Fan speed may also reduce until the air
cools.

Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community's regulations and standards
for recycling and disposing of automotive
fluids.
Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the
coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 343).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
