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/deactiva -
tion
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 Defroster
Air recirculation
Rear Defroster
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 icon 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).
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.

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.
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
temperature settings for best wind -
shield and side window defrosting and defog -
ging.
Rear Defrost
Push the Rear Defrost button to acti -
vate (indicators illuminated) the
Rear Defroster.
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
Defroster.
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
21_GU_OM_EN_USC_t.book Page 52

53

NOTE:

The MAX-DEF function remains active for
approximately three minutes once the engine
coolant reaches the proper temperature.
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.
If air distribution or the fan speed is manually
adjusted, the AUTO button indicator will turn
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.
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
21_GU_OM_EN_USC_t.book Page 53

54

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
conditions to provide cooler air out of the
panel outlets and warmer air from the floor
outlets.
Floor Mode
Air 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.
With the air conditioner is off:
Air recirculation is on
The A/C compressor is off
The fan is off

NOTE:

The Climate Control system stores the previ -
ously set temperatures and resumes opera -
tion 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 tempera
-
ture, quantity, and distribution of air intro -
duced into the passenger compartment. It
also controls air recirculation and the activa -
tion of the air conditioner.
At any time during automatic operation, you
can change the temperature, activate or deac -
tivate the Rear Defrost, activate SYNC, acti -
vate or deactivate the air conditioner, and
activate or deactivate air recirculation. The
system will automatically adjust to the new
settings.
Climate Control Display Settings

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 headlight 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 cause 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 10 minutes.
Have the system inspected at an authorized
dealer before the summer.
