Washer Fluid For Windshield/Headlights
The windshield and headlight (if equipped)
washer fluid reservoir is equipped with a tele-
scopic filler neck.
If the level is too low, remove reservoir cap and
lift the filler neck. Then, add the fluid
described
Ú
page 263. After filling the reser -
voir, lower the filler neck and install the reser -
voir cap until you hear it click.

NOTE:

The headlight washers are activated every 10
activations of the windshield washer.
note:
The headlight washing system will not work if
the liquid level is low (situation indicated by
the symbol on the instrument cluster display

Ú
page 69). The windshield washer will keep
working.
On vehicles equipped with headlight washers,
there is a reference notch on the dipstick:
ONLY the windshield/rear window washer
operates with the level below this reference.
Brake Fluid
Check that the fluid is at the maximum level. If
the fluid level in the tank is low, contact an
authorized dealer to have the system checked.
Automatic Transmission Activation System
Oil
The transmission control oil level should only
be checked at an authorized dealer.
Useful Advice For Extending The Life Of
Your Battery
To avoid draining your battery and make it last
longer, observe the following instructions:
When you park the vehicle, ensure that the
doors and liftgate are closed properly to
prevent any lights from remaining on inside
the passenger's compartment.
Do not keep accessories (e.g. radio, hazard
warning lights, etc.) switched on for a long
time when the engine is not running.
Before performing any operation on the
electrical system, disconnect the negative
battery cable.
If you wish to install electrical accessories
after purchasing the vehicle that require
permanent electrical supply (e.g. alarm, etc.),
or accessories which influence the electrical
supply requirements, contact an authorized
dealer, who’s qualified staff will evaluate the
overall electrical consumption.
NOTE:

After the battery is disconnected, the steering
must be initialized. The warning light on the
instrument cluster display switches on to indi
-
cate this. To carry out this procedure, simply
turn the steering wheel all the way from one
end to the other, and then turn it back to the
central position.Battery
The battery does not require the electrolyte to
be topped up with distilled water. A periodic
check carried out at an authorized dealer,
however, is necessary to check efficiency.
Follow the battery manufacturer's instructions
for maintenance.
CAUTION!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulfation, reducing its capacity and
efficiency during the vehicle start. The
battery is also more prone to the risk of
freezing (at temperatures as high as 14°F
(-10°C).

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 corre-
sponds 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 (EPB) is
not activated.
Carry out the “Liftgate Emergency Opening”
procedure
Ú
page 62.
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 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’s side door is closed.
BODYWORK
Protection Against Atmospheric Agents
The vehicle is equipped with the best available
technological solutions to protect the body -
work 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.
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.
21_GU_OM_EN_USC_t.book Page 249

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
Ú
page 218.

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. 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 micro
-
fiber cloth must not have been previously
soaked in other substances or detergents.
Leather Seats
Remove the dry dirt with a chamois or slightly
damp cloth, without exerting too much pres -
sure.
Remove any liquid or grease stains using an
absorbent dry cloth, without rubbing. Then
clean with a soft cloth or buckskin cloth damp -
ened with water and mild soap. If the stain
persists, use specific products and observe
the instructions carefully.

NOTE:

Never use alcohol. Make sure that the
cleaning products used contain no alcohol or
alcohol derivatives, even in small quantities.
Plastic And Coated Parts
Clean interior plastic parts with a damp cloth (if
possible made from microfiber), and a solution
of water and neutral, non-abrasive detergent. To clean oily or persistent stains, use specific
products free from solvents and designed to
maintain the original appearance and color of
the components.
Remove any dust using a microfiber cloth, if
necessary moistened with water. The use of
paper tissues is not recommended as these
may leave residues.
Alcantara Parts — If Equipped
Alcantara parts maintenance procedure:
Treat the surface with a microfiber cloth
moistened with mild marseille soap and
water, taking care to apply a uniform light
pressure over the entire area (do not rub
vigorously).
Rinse and wring out the microfiber cloth,
and pass it over the entire area again.
Let it dry, and then brush gently with a soft
brush.
Genuine Leather Parts
Use only water and mild soap to clean these
parts. Never use alcohol or alcohol-based
products.
CAUTION!
Precautions have been taken to safeguard
all parts and connections however, the
pressures generated by these machines is
such that complete protection against
water ingress cannot be guaranteed.
