LUBRICATING MOVING PARTS OF THE
B
ODYWORK
Ensure that the locks and bodywork junction
points, including components such as the seat
guides, door hinges (and rollers), liftgate and
hood are periodically lubricated with
lithium-based grease to ensure correct,
silent operation and to protect them from
rust and wear.
Thoroughly clean the components, eliminating
every trace of dirt and dust. After lubricating,
eliminate excess oil and grease. Also pay
particular attention to the hood closing devices,
to ensure correct operation. Operations of the
hood are to be carried out with the engine cold.
Remember to check, clean and lubricate the
locking, release and safety devices. Lubricate the external lock barrels twice a year.
Apply a small amount of high-quality lubricant
directly into the lock barrel.
If necessary, contact an authorized dealer as
soon as possible.
WINDSHIELD WIPER
Periodically clean the windshield, rear window
and rubber profile of the windshield wiper blades,
using a sponge or a soft cloth and a non-abrasive
detergent. This eliminates the salt or impurities
accumulated when driving.
Prolonged operation of the windshield window
wipers with dry glass may cause the deterioration
of the blades, in addition to abrasion of the
surface of the glass. To eliminate the impurities
on the dry glass, always operate the windshield
washers.
In the event of very low outdoor temperatures,
below 0°F (-17.8°C), ensure that the movement
of the rubber part in contact with the glass is not
obstructed. Use a suitable deicing product to
release it if required.
Avoid using the windshield wipers to remove frost
or ice.
Also avoid contact of the rubber profile of the
blades with petroleum derivatives such as engine
oil, gas, etc.
NOTE:
The life of the windshield wiper blades varies
according to the usage frequency. It is advised to
replace the blades approximately once a year.
When the blades are worn, noise, marks on the
glass or streaks of water may be noticed. In the
presence of these conditions, clean the wind
-
shield wiper blades or, if necessary, replace
them.
Raising The Windshield Wiper Blades (“Service
Position” Function)
The “service position” function allows the driver
to replace the windshield wiper blades easily. It is
also recommended to activate this function when
it is snowing and to make it easier to remove any
dirt deposits in the area where the blades are
normally positioned, while washing.

NOTE:
If the windshield wipers are raised while not in
the “service position,” it is possible to damage
the hood.
WARNING!
Use only refrigerants and compressor
lubricants approved by the manufacturer for
your air conditioning system. Some
unapproved refrigerants are flammable and
can explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs. Refer to
Warranty Information Book, located in your
owner’s information kit, for further warranty
information.
WARNING!
Driving with worn windshield wiper blades is a
serious hazard, because visibility is reduced in
bad weather conditions.

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, 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 use the vehicle if irregular idling or
operating conditions are experienced.
COOLING SYSTEM
Coolant Check
Your vehicle has two cooling systems and both
need to be checked to ensure they are at proper
fill levels

Ú
page 204.
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
build-up of insects, leaves or other debris. Should
it be dirty, clean 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!
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.

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 200.

NOTE:

For topping off, and proper coolant specifi-
cations
Ú
page 252.
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 top of engine.
Any excess fluid that is spilled onto the top of
the engine should be removed using
compressed air or absorbent cloth. 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. 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 the 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 200.

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 unnecessary
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.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
WARNING!
WARNING!
Never add coolant with the engine hot or
overheated.

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
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! 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.
