Description
The Automatic Dual Zone Climate Control
System adjusts the temperature and air distri-
bution 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/dehu -
midifying the air)
Air recirculation The Climate Control System can also be oper
-
ated 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 below 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 illu-
minated 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 environmental conditions, windows
could fog up rapidly, since the air is not dehu -
midified. 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 illumi-
nated above the “A” on the Air Recirculation
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 Recir-
culation Button
The three operating conditions are obtained by
pushing the Air Recirculation Button in
sequence.
Enabling The Air Quality System (AQS) Func -
tion — If Equipped
When the automatic recirculation function is
selected, the AQS function automatically acti -
vates 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 compart
-
ment 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 tempera -
ture settings for best windshield and
side window defrosting and defogging.

Rear Defrost
Push the Rear Defrost button to acti -
vate (indicators 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 wind
-
shield 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 illumi -
nated) and current air distribution setting

NOTE:

The MAX-DEF function remains active for
approximately three minutes once the engine
coolant reaches the proper temperature.
21_GA_OM_EN_USC_t.book Page 52

53

When the function is on, AUTO mode will deac-
tivate. 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.
Air Temperature Adjustment
Rotate the driver or passenger Temperature
Adjustment Knob clockwise for warmer
temperatures or counterclockwise for cooler
temperatures. The set temperatures are
shown on the radio system.
Push the SYNC button to sync the driver and
passenger air temperatures.
Rotate the passenger Temperature Adjust -
ment Knob to cancel the SYNC function. This
will set a new passenger side temperature.
Rotate the Temperature Adjustment Knob fully
clockwise to engage the HI (maximum heating)
setting or fully counterclockwise to engage the
LO (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 auto -
matically 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 or .
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 Distribu-
tion 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 illumi -
nated on the radio system display
Minimum fan speed = one indicator illumi -
nated 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 distri -
bution.

NOTE:

In AUTO mode, the Climate Controls automati -
cally manage the air distribution. When set
manually, the respective symbols on the radio
system indicate the air distribution setting.
21_GA_OM_EN_USC_t.book Page 53

55

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 recir-
culation 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 will restart if the inside temperature
changes significantly, or if the LO setting, or
MAX-DEF setting, is activated.
With Stop/Start system on (engine is off), air
flow is reduced to keep the compartment
comfort conditions for longer.

Until the temperature drastically changes within
the cabin, the climate control system will
continue to maintain the temperature while the
engine is off. By deactivating the Stop/Start
system with the button (located by the head
-
light switch), the climate control system operates
normally according to the settings.

NOTE:

In harsh climate conditions, limit the use of
the Stop/Start system to prevent the
compressor from continuously switching on
and off. This will prevent rapid misting of the
windows and the accumulation of humidity
in the passenger compartment.
When the Stop/Start system is on, the
climate control system will always take air in
from outside, reducing the probability of the
windows fogging up.
System Maintenance
In winter months, the Climate Control system
must be turned on at least once a month for
approximately ten minutes.
Have the system inspected at an authorized
dealer before the summer.
INTERIOR STORAGE AND
EQUIPMENT
Glove Compartment
The glove compartment is located on the
passenger side of the instrument panel.
Opening The Glove Compartment
Pull the release handle to open the glove
compartment.
When the glove compartment is opened, a
light turns on to illuminate the inside of the
compartment.

NOTE:

If equipped with a lock, unlock the glove
compartment by placing the emergency key
in the lock on the handle.
Do not insert large objects that will prevent
the glove compartment from closing
completely.

System Manual Activation/Deactivation
To manually activate/deactivate the system,
push the button located in the control panel on
the left of the steering wheel.Stop/Start Button
System Activation
The activation of the system is indicated by the symbol lighting up on the display. In this
condition, the light on the button is off.
System Deactivation
A message will appear on the display when the
system is deactivated. In this condition, the
light on the button is on.

NOTE:

Each time the engine is started, the system is
activated regardless of where it was when it
was previously switched off.
Possible Reasons The Engine Does Not
Autostop
For higher comfort and increased safety, and
to reduce emissions, there are certain condi -
tions where the engine will not autostop
despite the system being active, such as:
Engine still cold.
Especially cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
Reverse gear engaged (e.g. for parking
maneuvers).
With the automatic climate control active,
an adequate cabin heating or cooling
comfort has not been reached or with
MAX-DEF function active.
During the first period of use, to initialize the
system.
Steering angle beyond threshold.
Engine Restarting Conditions
Due to comfort, emission control and safety
reasons, the engine can restart automatically
without any action by the driver, under special
conditions, such as:
Battery not sufficiently charged.
Vehicle moving (e.g. when driving on roads
with a grade).
Engine stopping by the Stop/Start system
for more than approximately three minutes.
With the automatic climate control active,
an adjustment in cabin heating or cooling is
made or with MAX-DEF function active.
Safety Functions

When the engine is stopped through the Stop/
Start system, if the driver releases their seat belt,
opens the driver's or passenger's door, or opens
the hood from inside the vehicle, the engine can
be restarted only by using the ignition.

This condition is indicated to the driver both
through a buzzer and a message on the instru-
ment cluster display.

Exhaust Gas The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained 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
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 odor -
less 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.

IN CASE OF EMERGENCY

200

Cable Disconnection
Once the engine is started, remove the
connection cables in reverse sequence, as
described below:
1. Disconnect the negative (-) jumper cablefrom the remote negative (-) post of the
discharged vehicle.
2. Disconnect the negative end (-) of the jumper cable from the negative (-) post of
the booster battery.
3. Disconnect the opposite end of the posi -
tive (+) jumper cable from the positive (+)
post of the booster battery.
4. Disconnect the positive (+) end of the jumper cable from the positive (+) post of
the vehicle with the discharged battery.
If frequent jump starting is required to start
your vehicle, you should have the battery and
charging system inspected at an authorized
dealer.Bump Starting
Never jump start the engine by pushing,
towing or coasting downhill.

NOTE:

You cannot start a vehicle with an automatic
transmission by pushing it.
IF YOUR ENGINE OVERHEATS
Engine overheating may occur in situations of
extreme environmental temperatures,
frequent engine stops/starts, or driving in
heavy traffic. If the engine becomes over -
heated, the Engine Temperature Warning
Light in the instrument cluster will illuminate
along with a dedicated message
Ú
page 73.
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the
transmission in NEUTRAL, but do not
increase engine idle speed.

NOTE:

There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s
battery, even when not in use (i.e., cellular
phones, etc.). Eventually, if plugged in long
enough without engine operation, the
vehicle’s battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If temperature gauge
reads “H”, pull over and stop the vehicle.
Idle the vehicle with the air conditioner
turned off until the pointer drops back into
the normal range. If the pointer remains on
the “H”, turn the engine off immediately,
and call for service.
