CHECKING LEVELS — 2.9L ENGINE
ENGINE OIL
The engine oil level can be seen on the
instrument cluster display every time the engine
is started, or on the Information and
Entertainment system display by activating on the
main menu (MENU button) the following
functions in sequence:
1. “Vehicle Information”
2. “Engine Oil”
Check that the oil level is between the MIN and
MAX level on the instrument cluster display using
the 6 notches shown. 1 notch displays the MIN
level and 6 notches displays the MAX level.

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.
If the oil level is close to or below the MIN mark,
add oil gradually through the filler, (refer to
“Top-Up And Oil Level Indication Update On
Display” in this section) considering that each
notch shown on the display corresponds to
approximately 8.8 fl oz (250 ml).The oil level can also be checked manually on
2.9L Quadrifoglio models.

CAUTION!
Make sure not to add too much oil when
topping off the engine. Engine oil in excess
may damage the engine. Have the vehicle
checked. Never exceed the MAX level when
topping off engine oil. It is advisable to check
the oil level in intermediate steps using the
oil dipstick (2.9L Quadrifoglio Only).

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.

NOTE:
If you have added the specified amount of oil and
the indicator is not reading “Full”, please contact
an authorized dealer.
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.

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.

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.
