Brake Fluid Level Check
Check the fluid level immediately if
the brake system
red warning
light and the related message turn on
indicating a low level of brake fluid.
• Clean the brake fluid reservoir area
around the cap before removing it.
• Add fluid to bring the level up to the
“MAX” mark on the side of the
master cylinder reservoir. Use only
manufacturer's recommended brake
fluid (see “Refillings” in section
"Features and Specifications").
• Once the correct level is reached,
firmly close the cap.
The brake pads wear could cause the
fluid level to fall. However, low fluid
level may be caused by a leak and arequires accurate checkup of the
braking system.
CAUTION!
The symbol
on the tank cap
identifies the synthetic type of brake
fluid, distinguishing it from the
mineral type. Using mineral fluids
damages the special rubber linings of
the brake system irreparably.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:www.P65Warnings.ca.gov/passenger-
vehicle
WARNING!
•To avoid contamination from foreign
materials or moisture, use only new
brake fluid or fluid that has been in
a tightly closed container. Keep the
master cylinder reservoir cap secured
at all times. Brake fluid in an open
container absorbs moisture from the
air resulting in a lower boiling point.
This may cause it to boil
unexpectedly during hard or
prolonged braking, resulting in
sudden brake failure. This could
result in an accident.
•Overfilling the brake fluid reservoir
can result in spilling brake fluid on
hot engine parts, causing the brake
fluid to catch fire. Brake fluid can
also damage painted and vinyl
surfaces, make sure it does not spill
over these surfaces.
•Do not allow petroleum based fluid
to contaminate the brake fluid.
Brake seal components could be
damaged, causing partial or
complete brake failure. This could
result in an accident.

• Every time the battery is
reconnected the

Useful Advice to Extend
Battery Life
When parking the vehicle, make sure
that the doors, front, rear lids and
flaps are properly closed. All interior
lights should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning flashers, fan, etc.).
CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing (this can happen even at
14°F/-10°C).
We recommend you to have the
battery charge condition checked,
preferably at the beginning of the
cold season, to prevent the electrolyte
from freezing.
This check should be carried out more
frequently if the vehicle is used mainly
for short trips or if it is equipped with
power absorbing devices that remain
permanently on even when the
ignition switch is off. This appliesabove all if these devices have been
retrofitted ("Aftermarket" services).
If the vehicle is not used for long
periods of time, please see “Vehicle
Stored for Long Periods” in this
section.
Battery Recharge
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times.
•Before using a charger device
always check that this tool is
suitable for the installed battery,
with constant voltage (lower than
14.8 V) and low amperage
(maximum limit 15 A).
•Recharge the battery in a
well-ventilated environment.
•Never charge or recharge a frozen
battery: it can explode due to
hydrogen trapped inside the ice
crystals.
•Ensure that any sparks or open

• Undo the four retaining screws and
remove the cover.
The fuses are housed in three control
boxes.The following table points out the

CAUTION!
If you need to wash the engine
compartment, do not direct the jet of
water for too long directly on the
