Function Deactivation
The function is deactivated if:
More than two minutes passes before placing
the ignition in the STOP position after having
raised the lever and putting the wipers into
service position.
The ignition is placed in the ACC position and
the windshield wiper control is used.
If, after using the function, the ignition is set back
to ACC with the blades in a position other than
rest position (at the base of the windshield), they
will only return to rest position following a
command given using the stalk (stalk upwards,
into unstable position) or when a speed of 3 mph
(5 km/h) is exceeded.
Replacing The Windshield Wiper Blades
Proceed as follows:
1. Raise the wiper arm, press tab of the attach -
ment spring and remove the blade from the
arm.
Wiper Release Tab 2. Fit the new blade, inserting the tab in the
dedicated housing in the arm and checking
that it is locked.
3. Lower the wiper arm onto the windshield.

NOTE:
Do not operate the windshield wiper with the
blades lifted from the windshield.
Windshield Washer
The window washer nozzles are fixed. If there is
no jet of fluid, first check that there is fluid in the
reservoir.
Windshield Washers
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 an 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.

ENGINE COOLING SYSTEM
Coolant Check
Your vehicle has two cooling systems and they
both need to be checked to ensure they are at
proper fill levels.
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 for any
buildup 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.

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.
For the correct servicing intervals

Ú
page 182.

NOTE:

For topping up, use a fluid with the same
characteristics as those indicated on

Ú
page 233.
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.
Use care when filling under hood fluids such as
engine oil, windshield washer fluid, antifreeze
etc. to minimize spillage onto the top of the
engine. Any excess fluid that is spilled onto the
top of the engine should be removed using
compressed air or an absorbent cloth.
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.
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 position. The fan is
temperature controlled and can start at any
time the ignition is in the ON position.
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.
WARNING!

(Continued)
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.
Disposal Of Used Coolant
Disposal of engine/intercooler coolant is subject
to legal requirements: consult the appropriate
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.
BRAKING SYSTEM
In order to guarantee the efficiency of the braking
system, periodically check its components; for
this operation, contact an authorized dealer.
For the correct servicing intervals

Ú
page 182.

NOTE:
Driving with your foot resting on the brake pedal
may compromise its efficiency, increasing the
risk of accidents. When driving, never keep your
foot on the brake pedal and don’t put unneces
-
sary strain on it to prevent the brakes from over -
heating: excess pad wear may cause damage to
the braking system.
When an insufficient oil level is detected,
contact an authorized dealer to have the
system checked.
Always keep the cap of the brake fluid
reservoir (in the engine compartment)
completely closed.
AUTOMATIC TRANSMISSION
Use only a transmission oil with the same charac -
teristics as those indicated on
Ú
page 234.
Special Additives
Do not use any type of additive with the
automatic transmission oil. The automatic
transmission oil is a product designed especially
for this vehicle and its performance may be
compromised through the use of further
additives.
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.
WARNING!
Use only the manufacturer recommended
brake fluid
Ú
page 234. Using the wrong
type of brake fluid can severely damage your
brake system and/or impair its performance.
The proper type of brake fluid for your vehicle
is also identified on the original factory
installed hydraulic master cylinder reservoir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in an open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING!

Frequency Of Oil Changes
In normal vehicle operating conditions, it is not
necessary to change the transmission oil.
REPLACING THE BATTERY
If necessary, replace the battery with another
battery with the same specifications. It is advised
to contact an authorized dealer for replacement.

NOTE:
Each time the 12V battery is reconnected, cycle
the steering wheel all the way to the left. Then
cycle the steering wheel all the way to the right to
allow the steering angle sensor to learn the
steering angle thresholds. Follow the battery manufacturer's instructions for
maintenance.

NOTE:
It will not be possible to open the trunk with a key
or by pressing the button in the passenger
compartment when the battery is disconnected.
So, always position the manual trunk opening
strap on the trunk lock before disconnecting the
battery

Ú
page 220.
FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
electrical circuit inside of the fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never
replace a fuse with another fuse of higher
amp rating. Never replace a blown fuse with
metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity or
vice versa. Failure to use proper fuses may
result in serious personal injury, fire and/or
property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety
systems (air bag system, braking system),
power unit systems (engine system,
transmission system) or steering system
blows, contact an authorized dealer.

TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
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.
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 30 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 placing the ignition in STOP and having
closed the driver side door, wait at least one
minute before disconnecting the electrical supply
from the battery. When reconnecting the elec
-
trical supply to the battery, make sure that the
ignition is in the STOP position and the driver side
door is closed.
WARNING!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.

PRESERVING THE BODYWORK
Paint
Touch up abrasions and scratches immediately
to prevent the formation of rust.
Maintenance of paintwork consists of washing
the car: the frequency depends on the conditions
and environment where the car is used. For
example, it is advisable to wash the vehicle more
often in areas with high levels of atmospheric
pollution or salted roads.
Some parts of the vehicle may be covered with a
matte paint which, in order to be maintained
intact, requires special care.
To correctly wash the vehicle, follow these
instructions:
If high pressure jets or cleaners are used to
wash the vehicle, keep a distance of at least
15 inches (40 cm) from the bodywork to avoid
damage or alteration. Build up of water could
cause damage to the vehicle in the long term.
To make it easier to remove any dirt deposits
in the area where the blades are normally
located it is recommended to position the
windshield wipers vertically (service position).
Wash the bodywork using a low pressure jet of
water if possible.
Wipe a sponge with a slightly soapy solution
over the bodywork, frequently rinsing the
sponge.
Rinse well with water and dry with a leather
chamois.
Dry the less visible parts (e.g. door frames, hood,
headlight frames, etc.) with special care, as water
may stagnate more easily in these areas. Do not wash the car after it has been left in the sun or
with the hood hot: this may alter the shine of the
paintwork.
Exterior plastic parts must be cleaned in the
same way as the rest of the vehicle.
If washing the car in a service that moves the car,
for cars with automatic transmissions, PARK (P)
must be cut out. You have to shut off the engine
in the following conditions: car stopped,
transmission in NEUTRAL (N), push the starter
button for at least three seconds.

NOTE:
Avoid parking under trees; the resin dropped by
trees makes the paintwork go opaque and
increases the possibility of corrosion.
Windows

Use specific detergents and clean cloths to
prevent scratching or altering the transparency.
Front Headlights
Use a soft cloth soaked in water and detergent for
washing cars.

NOTE:

Never use aromatic substances (e.g. gasoline)
or ketones (e.g. acetone) for cleaning the
plastic lenses of the headlights.
When cleaning with a pressure washer, keep
the pressure washer at least eight inches
(20 cm) away from the headlights. Engine Compartment

At the end of every Winter, wash the engine
compartment thoroughly, taking care not to aim
the jet of water directly at the electronic control
units or at the windshield wiper motors. Have this
operation performed at a specialized workshop.
For further information

Ú
page 191.

NOTE:
The washing should take place with the engine
cold and the ignition device in the STOP position.
After the washing operation, make sure that the
various protections (e.g. rubber caps and guards)
have not been removed or damaged.
INTERIORS
Periodically check the cleanliness of the interior,
beneath the mats, which could cause oxidation of
the sheet metal.
SEATS AND FABRIC PARTS
Remove dust with a soft brush or a vacuum
cleaner. Rub the seats with a sponge moistened
with a solution of water and neutral detergent.

Cleaning heat press images on seats — if equipped:

Due to the color, opacity and wear-resistant
protection with which the heat press images on
some seats are made, they may be subject to
temporary scratching if they are touched by finger
nails, keys, or other hard objects. In such cases,
the visible signs do not impair the profiled
images, and can easily be removed by wiping the
affected area with a microfiber cloth moistened
with water (not dry) to restore the seat to its
original condition. The microfiber cloth must not
have been previously soaked in other substances
or detergents.
CAUTION!
Wipe the rear window inside gently with a
cloth following the direction of the filaments to
avoid damaging the heating device.
