(Continued)
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.

J-CASE Fuse
Fuse Extracting Pliers
To replace a fuse, use the pliers hooked to the
fuse box.
Fuse Box Grab the pliers from the upper tabs, press them,
and extract the pliers pulling upwards.
The pliers have two different ends, both of which
are specifically designed to remove the different
types of fuses present in the vehicle:
Fuse Extracting Pliers
After use, return the pliers to their proper position
using the following procedures:
Grasp the pliers from the upper tabs and insert
them into their housing.
Push downward on the pliers into their housing
until they click into place.
1 — Electrical Circuit
2 — Case Fuse With Good Electrical Circuit
3 — Case Fuse With Bad Electrical Circuit
1 — MINI fuse
2 — J-CASE fuse
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.
23_GU_OM_EN_USC_t.book Page 215

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 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 elec-
trical supply to the battery, make sure that the
ignition is in the STOP position and the driver’s
side door is closed.
BODYWORK
PROTECTION AGAINST ATMOSPHERIC
A
GENTS
The vehicle is equipped with the best available
technological solutions to protect the bodywork
against corrosion.
These include:
Painting products and systems which give the
vehicle resistance to corrosion and abrasion.
Use of galvanized (or pre-treated) steel sheets,
with high resistance to corrosion.
Spraying of plastic parts, with a protective
function in the more exposed points: under
door, inner wing, edges, etc.
Use of “open” boxed sections to prevent
condensation and pockets of moisture which
could favor the formation of rust inside.
Use of special films to protect against abrasion
in exposed areas (e.g. rear wing, doors, etc.).
CORROSION WARRANTY
Your vehicle is covered by Corrosion Warranty
against perforation due to rust of any original
element of the structure or bodywork. For the
general terms of this warranty, refer to the
Warranty Booklet.
PRESERVING THE BODYWORK
Paint
Touch up abrasions and scratches immediately to
prevent the formation of rust.
Maintenance of paintwork consists of washing
the vehicle: the frequency depends on the
conditions and environment where the vehicle 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)

Ú
page 209.
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 vehicle after it has been left in the sun
or with the hood hot: this may alter the shine of
the paintwork.

NOTE:
Avoid parking under trees; the resin dropped by
trees makes the paintwork go opaque and
increases the possibility of corrosion.
Exterior plastic parts must be cleaned in the
same way as the rest of the vehicle.
If washing the vehicle in a service that moves the
vehicle, for vehicles with automatic
transmissions, proceed with the following
directions:
Ensure that the vehicle is on a flat surface.
Disable the automatic engagement of the
parking brake
Ú
page 89.
With the vehicle stationary, the gear in
NEUTRAL (N) and the brake pedal pressed,
push the START button.

NOTE:
The vehicle will remain in NEUTRAL (N) for
15 minutes before PARK (P) will be engaged
automatically.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 vehicles.

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

Ú
page 208.

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. It is advised to use a moist brush on
velvet upholstery. 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.

(Continued)
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the respon
-
sibility of the manufacturer and may void or not
be covered under New Vehicle Limited Warranty.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the engine,
emissions, and fuel system components.
Problems that result from running CNG or LP are
not the responsibility of the manufacturer and
may void or not be covered under the New
Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic
additive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system
performance in some vehicles. The manufacturer
recommends that gasoline without MMT be used
in your vehicle. The MMT content of gasoline may
not be indicated on the gasoline pump; therefore,
you should ask your gasoline retailer whether the
gasoline contains MMT. MMT is prohibited in
Federal and California reformulated gasoline.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of TOP TIER Detergent
Gasoline is recommended. Visit

www.toptiergas.com
for a list of TOP TIER
Detergent Gasoline retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials
intended for gum and varnish removal may
contain active solvents or similar ingredients.
These can harm fuel system gasket and
diaphragm materials.
FUEL SYSTEM CAUTIONS
NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being
assessed against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage the
emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the catalytic
converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc-
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle performance
problems resulting from the use of such fuels
or additives is not the responsibility of the
manufacturer and may void or not be
covered under the New Vehicle Limited
Warranty.
CAUTION!
