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:

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.
A/C Compressor
Push the A/C buttonto 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
environmental conditions, windows
could fog up rapidly, since the air is not
dehumidified.
Front Defroster And
MAX-DEF Function
Push the Front Defroster 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

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 Defroster
Display the fan speed (indicators
illuminated) and current air distribution
setting
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 deactivate. The only manual
operations possible are adjusting
blower speed and turning off the Rear
Window Defroster.
Pushing the
button switches off the
MAX-DEF function.
Rear Defroster
Push the Rear Defrosterbutton to
activate (indicators illuminated) the Rear

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 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.

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.
199

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
217

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 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.

SERVICING AND MAINTENANCE

Temperature Grades
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire
life, and excessive temperature can
lead to sudden tire failure. The grade C
corresponds to a level of performance,
which all passenger vehicle tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B
and A represent higher levels of
performance on the laboratory test
wheel, than the minimum required by
law.
Warning!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
STORING THE
VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Park the car 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 car 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 to the left of the lock
and extract the strap connected to it.
