Description
The Automatic Dual Zone Climate Control System
adjusts the temperature and air distribution
independently between the driver and passenger.
The system maintains the set temperature inside
the passenger compartment and compensates
for outside temperature change.

NOTE:
The reference temperature is 72°F (22°C) for
optimal comfort management.
The automatic setting will adjust the following to
maintain comfort within the passenger
compartment:
Air temperature from the driver/front
passenger side vents
Air distribution from the driver/front passenger
side vents
Fan speed (continuous variation of the air flow)
Compressor variations (for cooling/dehumid-
ifying the air)
Air recirculation The Climate Control system can also be operated
manually by using the buttons and knobs on the
faceplate.
Manual selections will override the automatic
settings, which are stored until the AUTO button is
pushed. If the system intervenes for safety
reasons, the automatic setting will take control of
the system.
The following operations will not deactivate the
automatic (AUTO) function:
Air Recirculation activation/deactivation
A/C activation/deactivation
SYNC function activation
Rear Window Defrost activation/deactivation
When in AUTO mode, the vehicle’s internal
temperature is controlled according to the set
temperature.
The following can be manually set or adjusted:
Driver/passenger air temperature
Blower speed (continuous variation)
Air distribution (seven positions for driver and
passenger)
A/C activation
Front Defrost
Air recirculation
Rear Defrost
System deactivation A/C Compressor
Push the A/C button or the icon to activate or
deactivate the A/C compressor (indicator
illuminated when activated). The A/C compressor
will remain off even after the engine has stopped.
When the A/C compressor is turned off, the
system deactivates air recirculation to prevent
the windows from fogging up. If the climate
control system can maintain the temperature,
with the A/C turned off, the AUTO feature will
remain on and the AUTO button indicator light will
not switch off.
To restore automatic control of the A/C
compressor, push the A/C button or the AUTO
button. With the A/C compressor off, the air
speed can be set manually using the Air Speed
Adjustment Knob.
When the A/C compressor is on, and the engine
is running, air speed cannot be lower than the
minimum speed (only one indicator light is lit).

NOTE:
When the A/C is off, the Climate Control system
can not produce air that is colder than the current
outside temperature. Under certain environ
-
mental conditions, windows could fog up rapidly,
since the air is not dehumidified.
CAUTION!
The system uses R1234yf refrigerant, which
does not pollute the environment in the event
of accidental leakage. Under no
circumstances, use R134a and R12 fluids,
which are incompatible with the components
of this system.

Air Recirculation And Air Quality System (AQS)Air Recirculation is managed according
to the following operating mode:
Automatic engagement: indicator is
illuminated above the “A” on the Air Recircu -
lation Button
Forced activation (air circulation always
activated): indicator illuminated above the
icon on the Air Recirculation Button
Forced deactivation (air recirculation always
off with intake of outside air): both indicators
not illuminated on the Air Recirculation Button
The three operating conditions are obtained by
pushing the Air Recirculation Button in
sequence.
Enabling The Air Quality System (AQS) Function —
If Equipped
When the automatic recirculation function is
selected, the AQS function automatically
activates internal air recirculation when the
outside air is polluted (e.g. in heavy traffic and
tunnels).
At low external temperatures or in high humidity,
the automatic function turns off to avoid fogging
up the windows. The user can select the function
again by pushing the Air Recirculation Button.
In automatic operation, air recirculation will be
controlled by the system according to outside
environmental conditions.

NOTE:

With the AQS function active and after the
internal air recirculation system has been
functioning for a set amount of time, the
Climate Control System enables air intake to
cycle the air in the passenger compartment for
a set time. The AQS function is disabled during
the air changes.
The engagement of the recirculation system
makes it possible to reach the required
heating or cooling conditions faster. It is,
however, inadvisable to use it on rainy/cold
days as it can increase the possibility of the
windows fogging. When the outside
temperature is low, recirculation is forced off
to prevent the windows from fogging up.
Front Defrost Air comes from the windshield and side
window demist outlets. Use Defrost
mode with maximum temperature
settings for best windshield and side
window defrosting and defogging.
Rear Defrost
Push the Rear Defrost button to activate
(indicator illuminated) the Rear Defrost.
The Rear Defrost will turn off after 20 minutes or
once the engine is turned off.

NOTE:
To avoid damage, do not apply stickers over the
interior heating filaments of the Rear Defrost. Front Defrost And MAX-DEF Function
Push the MAX-DEF button (indicator
illuminated) to defrost the windshield
and side windows.
While in MAX-DEF function, the air conditioner
will:
Activate the air conditioner compressor when
the weather allows
Turn air recirculation off
Set the maximum air temperature (HI) on both
the driver and passenger side
Activate a blower speed based on the
temperature of the engine coolant
Adjust the air flow towards the windshield and
front side windows
Activate the Rear Window Defrost
Display the fan speed (indicators illuminated)
and current air distribution setting

NOTE:
The MAX-DEF function remains active for approx -
imately three minutes once the engine coolant
reaches the proper temperature.
When the function is on, AUTO mode will
deactivate. The only manual operations possible
are adjusting blower speed and turning off the
Rear Window Defrost.
Pushing the button switches off the MAX-DEF
function.

(maximum cooling) setting. To deactivate these
functions, rotate the Temperature Adjustment
Knob to the desired temperature.
Rear passengers’ temperature is linked to driver
side selection.
AUTO Button
When the AUTO button is pushed (indicator
illuminated), the Climate Control system automat-
ically adjusts the following settings:
Quantity and distribution of air flow in the
passenger compartment
The air conditioner
Air recirculation
Cancels any manual settings
Selecting the AUTO function illuminates the
indicator on the A/C button.
If air distribution or the fan speed is manually
adjusted, the AUTO button indicator turns off to
indicate that the Climate Control system is no
longer in AUTO mode. After a manual adjustment, push the AUTO button
to resume the automatic system.
SYNC Button
Push the SYNC button (indicator illuminated) to
sync the passenger side air temperature with the
driver side air temperature.
This function makes temperature regulation
easier when the driver is traveling alone.
Turn the passenger Temperature Adjustment
Knob or push the passenger side Air Distribution
Selection Button to change the passenger side air
temperature and return to separate air
temperature management.
Blower Speed
Turn the Blower Speed Knob to increase or
decrease the blower speed. The speed is
displayed with lighted indicators in the radio
system display.
Maximum fan speed = all indicators
illuminated on the radio system display
Minimum fan speed = one indicator
illuminated on the radio system display
The fan can be turned off by rotating the Blower
Speed Knob counterclockwise to the off position
(all segments on the radio system display are
turned off).

NOTE:
To restore automatic control of the fan speed,
push the AUTO button. Air Distribution Selection
Push the Air Distribution Selection button on the
faceplate to change the mode of air distribution.

NOTE:
In AUTO mode, the Climate Controls automatically
manage the air distribution. When set manually,
the respective symbols on the radio system indi
-
cate the air distribution setting.
Panel Mode
Air comes from the outlets in the
instrument panel to ventilate the chest
and face. Each of these outlets can be
individually adjusted to direct the flow of
air. The air vanes of the center outlets and
outboard outlets can be moved up and down or
side to side to regulate airflow direction. There is
a shut-off wheel located below the air vanes to
shut off or adjust the amount of airflow from
these outlets.
Bi-Level Mode
Air comes from the instrument panel
outlets and floor outlets. A slight
amount of air is directed through the
defrost and side window demister
outlets.

NOTE:
Bi-Level mode is designed under comfort condi -
tions to provide cooler air out of the panel outlets
and warmer air from the floor outlets.
23_GA_OM_EN_USC_t.book Page 53

Floor ModeAir comes from the floor outlets. A slight
amount of air is directed through the
defrost and side window demister
outlets. This setting heats the
passenger compartment the quickest.
Mix Mode
Air is directed through the floor, defrost,
and side window demister outlets. This
setting works best in cold or snowy
conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the
windshield.
Front Defrost And Panel Mode
Air flow is distributed between the
windshield demisting/defrosting vents
and side/central dashboard vents. This
setting allows air to flow to the
windshield on sunny days.
Front Defrost And Bi-Level Mode
Air flow is distributed to all vents.
Switching The Climate Control System On/Off
To Turn Off The Climate Control System
Rotate the Air Speed Adjustment Knob
completely counterclockwise to turn off the
Climate Control system.
When the air conditioner is off:
Air recirculation is on
The A/C compressor is off
The fan is off
The heated rear window can be activated/
deactivated

NOTE:
The climate control system stores the previously
set temperatures and resumes operation when
any button on the system is pushed.
To Turn On The Climate Control System
To switch the climate control system on in
automatic mode, push the AUTO button.
Operating Mode
The Climate Control system can be activated in
different ways. It is recommended to use the
automatic function. Push the AUTO button and
set the desired temperatures.
The automatic system adjusts the temperature,
quantity, and distribution of air introduced into
the passenger compartment. It also controls air
recirculation and the activation of the air
conditioner.
At any time during automatic operation, you can
change the temperature, activate or deactivate
the Rear Defrost, activate SYNC, activate or
deactivate the air conditioner, and activate or
deactivate air recirculation. The system will
automatically adjust to the new settings.

radio screen.
The display on the radio system is a pop up
window, which is activated by pushing the
buttons or turning the knobs on the Climate
Control system. The indicator lights located on the number of buttons and knobs indicate that
the selected feature is on/off. If no operation is
performed for a predetermined time, the pop-up
will close on the display.
Humidity Sensor
The Humidity Sensor helps prevent the windows
from fogging up. The AUTO function (indicator
illuminated) must be on for the Humidity Sensor
to function.
When outside temperature is low, the system
may turn the compressor on and turn air recircu
-
lation off for safer driving.
Stop/Start
The Stop/Start system shuts off the engine when
the vehicle speed is 0 mph (0 km/h), as a fuel
conservation measure.
In order to maintain comfort in the cabin, the
Stop/Start feature will not activate if any of the
following conditions exist:
The climate control system is in AUTO mode
(indicator illuminated), and the vehicle has yet
to reach the set temperature
The climate control system is in LO maximum
cooling
The climate control system is in HI maximum
heating
The climate control system is in the MAX-DEF
status
When the Stop/Start system is active, the engine

OPERATING MODE
Stopping the Engine
With the vehicle at a standstill and brake pedal
pressed, the Stop/Start system shuts off the
engine if the gear selector is in a position other
than REVERSE (R).
The system does not operate when the gear
selector is in REVERSE (R), in order to make
parking maneuvers easier.
In the event of uphill stops, the Stop/Start system
is disabled to make the “Hill Start Assist” function
available (works only with running engine).

NOTE:
The engine can only be automatically stopped
after having run at about 6 mph (10 km/h). After
an automatic restart, the vehicle only needs to
exceed a speed of 0.3 mph (0.5 km/h) to stop the
engine.
Engine stopping is signaled by the symbol
lighting up on the instrument cluster display.
Restarting the Engine
To restart the engine, release the brake pedal or
turn the steering wheel slightly (if equipped).
With the brake pressed and the transmission in
automatic mode DRIVE (D), the engine will restart
by shifting to REVERSE (R), to PARK (P) or to

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the
underside or rear of the vehicle is damaged, have
an authorized dealer inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned
parts. Open seams or loose connections could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been
properly installed and is secured to your
vehicle using the floor mat fasteners by
lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit
in a parked vehicle with the engine running
for an extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period, adjust
the ventilation system to force fresh, outside
air into the vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock your
vehicle.
