NOTE:
Always reinstall the oil cap and tighten to proper
torque whenever it is removed to add oil to
engine. Never run the engine with cap removed
as this could cause oil to leak from engine.
Manual Oil Level Checking Procedure —
2.9L Quadrifoglio
Check that the oil level is between the MIN and
MAX marks on dipstick, clean it with a lint-free
cloth and reinsert it. Extract the dipstick again
and check that the level is between the MIN and
MAX marks.
Top-Up And Oil Level Indication Update On
Display — 2.9L Quadrifoglio
If an engine oil top-off is needed, in order to
ensure the correct indication of the oil level on
the display, proceed with the following process:
Leave the car on flat ground with the engine
running for approximately five minutes
(temperature higher than 198°F (90°C) and
shut the engine off.
Wait for five minutes, turn the ignition to the
ACC mode without starting the engine and wait
for a few seconds.

NOTE:
If the level indication is not updated after the
previously described procedure, repeat the
engine adjustment, shut the engine off and wait
another five minutes before starting it again. If
the indication is not updated after the second
start, contact an authorized dealer.
Top-Up And Oil Level Indication Update On
Display — 2.0L
If an engine oil top-off is needed, in order to
ensure the correct indication of the oil level on
the display, proceed with the following process:
Leave the car on flat ground with the engine
running for approximately five minutes
(temperature higher than 176°F (80°C) and
shut the engine off.
Start the engine again and idle it for about
two minutes.

ENGINE COOLANT FLUID
If the level is too low, unscrew the cap of the
reservoir and add the fluid described

Ú
page 252.
WASHER FLUID FOR WINDSHIELD/
H
EADLIGHTS
The windshield and headlight (if equipped)
washer fluid reservoir is equipped with a
telescopic filler neck.
If the level is too low, remove reservoir cap and lift
the filler neck. Then, add the fluid described

Ú
page 252. After filling the reservoir, lower the
filler neck and install the reservoir cap until you
hear it click.
CAUTION!
The oil level is not refreshed immediately on
the display after topping off. Consequently,
wait for the oil level to be refreshed on the
display and follow the procedure below.
WARNING!
If the engine oil is being topped up, wait for the
engine to cool down before loosening the filler
cap, particularly for vehicles with aluminum
cap (if equipped). WARNING: risk of burns!
CAUTION!
The oil level must never exceed the MAX mark.
If the MAX mark is exceeded (last notch on
the right turns red) after the fill-up, go to an
authorized dealer as soon as possible to have
the oil in excess removed.
Do not add oil with specifications different
from those of the oil already in the engine.
Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters, we
advise you to contact an authorized dealer.
23_GU_OM_EN_USC_t.book Page 206

207

NOTE:
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.

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 70). 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 oper -
ates 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
S
YSTEM OIL
The transmission control oil level should only be
checked at an authorized dealer.
USEFUL ADVICE FOR EXTENDING THE LIFE
O
F 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 Power Steering
Warning Light on the instrument cluster display
switches on to indicate 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.
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).
WARNING!
Battery acid is a corrosive solution and can
burn or even blind you. Do not allow battery
acid to contact your eyes, skin, or clothing.
Do not lean over a battery when attaching
clamps. If acid splashes in eyes or on skin,
flush the area immediately with large
amounts of water

Ú
page 192.
Battery gas is flammable and explosive.
Keep flame or sparks away from the battery.
Do not use a booster battery or any other
booster source with an output greater than
12 Volts. Do not allow cable clamps to touch
each other.
Battery posts, terminals, and related
accessories contain lead and lead
compounds. Wash hands after handling.
23_GU_OM_EN_USC_t.book Page 207

239

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.
23_GU_OM_EN_USC_t.book Page 239

SERVICING AND MAINTENANCE

240

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.
