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.
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/dehumidifying 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 below operations will not deactivate
the automatic (AUTO) function:
Air Recirculation activation/
deactivation

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
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
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.
45

Note:The climate control system stores
the previously set temperatures and
resumes operation when any button on
the system is pushed.
Switching On The Climate Control
System
To switch the climate control system on
in automatic mode, push the AUTO
button.
Stop/Start
The climate control system manages the
Stop/Start system. Stop/Start has the
engine shut off when vehicle speed is
0 mph (0 km/h) to maintain comfort
within the vehicle.
Stop/Start will deactivate in the
following scenarios:
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, 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 on the
dashboard, the climate control system
will take priority over the engine shutting
off.
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, 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.
POWER WINDOWS
Power Window Switches
The power window switches work with
the ignition in the ON position and for
three minutes after the ignition has been
placed in the STOP position. When one of
the front doors is opened, this operation
is disabled.
Driver Side Front Door Controls
The switches are located on the door
panel trim. All windows can be controlled
from the driver side door panel.

Warning!
An incorrectly anchored tether strap
could lead to increased head motion and
possible injury to the child. Use only the
anchorage position directly behind the child
seat to secure a child restraint top tether
strap.
If your vehicle is equipped with a split rear
seat, make sure the tether strap does not
slip into the opening between the seatbacks
as you remove slack in the strap.
Transporting Pets
Air Bags deploying in the front seat could
harm your pet. An unrestrained pet will be
thrown about and possibly injured, or
injure a passenger during panic braking or
in a collision.
Pets should be restrained in the rear seat
in pet harnesses or pet carriers that are
secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN
THE CARGO AREA.
Warning!
Do not leave children or animals inside
parked vehicles in hot weather. Interior heat
build-up may cause serious injury or death.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle. In
a collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
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.
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 a competent
mechanic 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.

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 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 conditions 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.
Reduced braking system vacuum (e.g.
if the brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on
roads with a grade).
Engine stopping by the Stop/Start
system for more than approx. 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 instrument cluster display.
Irregular Operation
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, see the "Warning
Lights and Messages" paragraph,
"Getting To Know Your Instrument Panel"
chapter.
Vehicle Inactivity
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of the
battery power supply.
Proceed as follows:
Remove connector from socket to
disconnect sensor (battery status
monitoring) installed on the negative pole
of the battery. This sensor should never
be disconnected from the pole except if
the battery is replaced.
147

ENGINE OVERHEATING
Engine overheating may occur in
situations of extreme environmental
temperatures, frequent engine
stops/starts, or driving in heavy traffic.
If the engine becomes overheated, the
Engine Temperature Warning Light in the
instrument cluster will illuminate along
with a dedicated message. Refer to
"Warning Lights And Messages" in the
"Getting To Know Your Instrument Panel"
for more information.
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.
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.
If Steam Is Coming From The Engine
Compartment
Do not go near the front of the vehicle.
Stop the engine. Wait until the steam
dissipates. Then, open the hood and start
the engine.
If Neither Coolant Nor Steam Is
Escaping
Open the hood and idle the engine until it
cools.
Note:
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and contact your authorized
dealer.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Contact your authorized dealer.
189

Then, check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
Exhaust System
Adequate maintenance of the engine
exhaust system represents the best
protection against leaks of carbon
monoxide into the passenger
compartment.
If an unusual noise from the exhaust or
the presence of smoke in the passenger
compartment is identified, or if the
underbody or rear section of the vehicle
have been damaged, have the entire
exhaust system and adjoining bodywork
areas checked at your authorized dealer
to identify any components which are
broken, damaged, worn or have moved
from their correct fitting position.Open welding or loose connections may
permit exhaust gas to enter the
passenger compartment.
Have the exhaust system checked every
time the vehicle is raised. Replace the
components where necessary (for these
operations, contact an authorized
dealer).
In normal operating conditions, the
catalytic converter does not require
maintenance. To ensure that it operates
correctly, however, and prevent it from
getting damaged, it is extremely
important that the engine operates
perfectly.
To minimize the risk of damaging the
catalytic converter, proceed as follows:
Do not stop the engine or deactivate
the ignition with gear engaged and
vehicle in motion.
Do not attempt to start the engine by
bump starting.
Do not persist in using the vehicle if
idling is very irregular or the operating
conditions are very notably irregular.
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.
A hot exhaust system can start a fire if
you park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system.
Do not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Cooling System
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 open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when the
hood is raised. The fan starts automatically
and may start at any time, whether the
engine is running or not.
When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.

Coolant Check
Your vehicle has two cooling systems and
they both need to be checked to ensure
they are at proper fill levels. Refer to the
“Engine Compartment” section for the
locations.
Check the engine coolant and intercooler
coolant level every oil change or before
long trips.
If there are impurities in the engine
coolant, the system must be drained,
flushed and refilled: contact an
authorized dealer.
Check the front part of the condenser to
check for any build-up of insects, leaves
or other debris. Should it be dirty, clean it
by spraying delicately with water.
Check the hoses of the engine/
intercooler cooling system to ensure that
the rubber has not deteriorated and that
there are no cracks, tears, cuts or
obstructions in the expansion tank side
and radiator side connectors. Should
there be any doubt regarding leaks from
the system (e.g. if frequent top ups are
required), have the seal checked at an
authorized dealer.
With the engine off and at normal
operating temperature, check that the
cooling system radiator cap is closed
properly.
Warning!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated
engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or
injury, do not remove the pressure cap while
the system is hot or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Note: Before removing the coolant
reservoir cap, wait for the system to cool
down.
Topping Up / Draining / Flushing The
Engine/Intercooler Coolant
If the engine coolant (antifreeze) is dirty,
have cleaning and flushing carried out at
an authorized dealer.
See the "Maintenance Plan" for the
correct servicing intervals.
Note:
For topping up, use a fluid with the
same characteristics as those indicated
in the "Fluids And Lubricants" table (see
"Technical Specifications" chapter).
Do not use pure water, alcohol-based
coolants, corrosions inhibitors or
additional anti-rust products because they may be incompatible with the
engine coolant and cause the clogging of
the radiator. The use of propylene
glycol-based coolant is also not
recommended.
Engine Cooling/Intercooler System Cap
To prevent loss of engine coolant, make
sure that the expansion tank cap is
closed. If it is open, screw it completely
until you reach/hear the click.
Periodically check the cap and clean it
from any foreign bodies that may have
deposited on the external surface.
Warning!
Never add coolant with the engine hot or
overheated.
Do not attempt to cool an overheated
engine by loosening or removing the cap.
The heat causes a considerable increase in
pressure in the cooling system.
To prevent damage to the engine, only use
the engine cooling circuit caps provided.
Disposal Of Used Coolant
Disposal of engine/intercooler coolant is
subject to legal requirements: contact
the appropriate body to determine local
regulations.
206
SERVICING AND MAINTENANCE

STORING THE VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Park the vehicle in an area that is
covered and dry, and well-ventilated if
possible. Slightly open the windows.
Check that the electric park brake is
not activated.
Carry out the procedure: “manual trunk
opening device” procedure described in
this paragraph.
Disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage.
If the battery is not disconnected from
the electrical system, check its state of
charge every thirty days.
Clean and protect the painted parts
using protective wax.
Clean and protect the shiny metal
parts using special compounds available
commercially.
Sprinkle talcum powder on the
windshield wiper rubber blades, and lift
them off the glass.
Cover the vehicle with a fabric or
perforated plastic sheet, paying
particular care not to damage the painted
surface by dragging any dust that may
have accumulated on it. Do not use
compact plastic sheets, as they do not
allow humidity to evaporate from the
surface of the vehicle .
Inflate tires to +7.25 psi (+0.5 bar)
above the standard prescribed pressure
and check it periodically.
Do not drain the engine cooling
system.
Any time the vehicle is left inactive for
two weeks or more, operate the air
conditioning system with engine idling
for at least five minutes, setting external
air and with fan set to maximum speed.
This operation will ensure appropriate
lubrication for the system, thus
minimizing the possibility of damage to
the compressor when the system is
operated again.
Note: After cycling the ignition to STOP
and having closed the driver side door,
wait at least one minute before
disconnecting the electrical supply from
the battery. When reconnecting the
electrical supply to the battery, make
sure that the ignition is in the STOP
position and the driver side door is
closed. Manual Trunk Opening Device
Proceed as follows if the battery needs
to be disconnected:
1. From the trunk interior covering,
rotate the plug counterclockwise of the
lock and extract the cord connected to it.
