Engine Coolant
If the level is too low, remove the cap of reser-
voir and add the fluid described on

Ú
page 267.
Washer Fluid For Windshield/Headlights
The windshield and headlights washer fluid
reservoir has a telescopic filler.
If the level is too low, remove reservoir cap and
lift the filler. Then, add the fluid described on

Ú
page 267.

NOTE:

The headlight washing system will not work if
the liquid level is low (as indicated by the
symbol on the instrument cluster display). 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 car, ensure that the
doors and trunk 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 car that require perma -
nent electrical supply (e.g. alarm, etc.), or
accessories which influence the electrical
supply requirements, contact an authorized
dealer, whose qualified staff will evaluate the
overall electrical consumption.
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.
CAUTION!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulphation, reducing its capacity and
efficiency during a vehicle start. The battery
is also more prone to the risk of freezing (at
temperatures as high as 14°F (-10°C).

NOTE:

After the battery is disconnected, the steering
must be initialized. The warning light on the
instrument panel 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 posi-
tion.
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.
Replacing The Battery
If necessary, replace the battery with another
original battery with the same specifications.
Follow the battery manufacturer’s instructions
for maintenance.
NOTE:

It will not be possible to open the trunk with a
key or by pushing the button in the passenger
compartment when the battery is discon
-
nected. So, always position the manual trunk
opening strap on the trunk lock before discon -
necting the battery
Ú
page 250.
Pressure Washing
Cleaning the engine compartment with a high
pressure washer is not recommended.
BATTERY RECHARGING
Important Notes

NOTE:

Before using the charging device, always
make sure that it is appropriate for the
installed battery, with constant voltage
(below 14.8 Volts) and low amperage
(maximum 15 Amps).
Recharge the battery in a well ventilated
environment.
Before using any devices to charge or to
maintain the charge of the battery, carefully
follow the instructions provided with the
device in order to properly and safely
connect it to the car battery.
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
Ú
page 199. If acid
splashes in eyes or on skin, flush the area
immediately with large amounts of water.
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.
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.
WARNING! (Continued)
WARNING!
Never charge or recharge a frozen battery:
it may explode because of the nitrogen
trapped inside the ice crystals.
At all times while charging or recharging
the battery, make sure that any sparks or
open flames are kept sufficiently far away
from the battery.
21_GA_OM_EN_USC_t.book Page 215

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.
