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.
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:

Automatic engagement: indicator is
illuminated above the “A” on the Air
Recirculation Button
Forced activation (air circulation
always activated): indicator illuminated
above the
iconontheAir
Recirculation Button
Forced deactivation (air recirculation
always off with intake of outside air):
both indicators 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

GETTING TO KNOW YOUR VEHICLE

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 stop 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
Evo 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 Evo 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 Evo 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.
Note:
After setting 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
mode and the driver side door is
closed.

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.
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.
REFUELING IN
EMERGENCY
Refueling in an emergency is described
in "Refueling The Vehicle" in "Starting
And Operating".
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.
197

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
andaidsinremovingheatfromthe
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.
TOWING A
DISABLED VEHICLE
This section describes procedures for
towing a disabled vehicle using a
commercial towing service.
Caution!
The vehicle should be transported with
all four wheels OFF the ground on the
flatbed of a roadside assistance vehicle.
Avoid towing with only the front (or rear)
wheels lifted. When towing with only the
front (or rear) wheels lifted, in addition to
damaging the body, it could damage the
transmission.
Do not use sling-type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flatbed
truck, do not attach to front or rear
suspension components. Damage to your
vehicle may result from improper towing.
Ensure that the Electric Park Brake is
released, and remain released, while being
towed.
Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.
198
IN CASE OF EMERGENCY

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!
Turn vehicle off and disconnect the fan
motor lead before working near the radiator
cooling fan.
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.
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 is hot.
Engine Coolant Check
Check the engine 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 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
215

(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 engine coolant
reservoir cap, wait for the system to
cool down.
Topping Up / Draining / Flushing
The Engine 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 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 Engine Coolant
Disposal of engine coolant is subject to
legal requirements: contact the
appropriate body to determine local
regulations.
Note:
To prevent the fluid from being
ingested by children or animals, do
not keep it in open containers or pour
it on the ground. If ingested, contact a
doctor immediately. Eliminate any
traces of fluid from the ground
immediately.
When the vehicle stops after a short
trip, steam may be seen coming out
from front of the hood. This is a
normal phenomenon which is due to
the presence of rain, snow or a lot of
moisture on the surface of the
radiator.
With engine and system cold, do
not top up with coolant beyond the
maximum level indicated on the
reservoir in the engine compartment.
