SERVICING AND MAINTENANCE

220

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 compart-
ment 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 compart -
ment.
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.
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 pres
-
sure 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 automat -
ically 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.

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 transpar -
ency. Front Headlights

Use a soft cloth soaked in water and detergent
for washing cars.

NOTE:

Never use aromatic substances (e.g. gaso -
line) 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 215.

NOTE:

The washing should take place with the engine
cold and the ignition device in the STOP posi -
tion. 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 inte -
rior, 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 moist -
ened 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 micro -
fiber 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.
