Restarting the Vehicle
Before restarting the vehicle after a
long period of inactivity, we
recommend that you carry out the
following operations.
• Check the tires for pressure and for
any damages, cuts or cracks. If this is
the case, have them replaced.
• Do not dry-rub the external surface
of the vehicle.
• Visually inspect if there are any fluid
leaks (oil, brake and clutch fluid,
engine coolant etc.).
• Have the engine oil and filter
replaced.
• Check the fluid levels in the brake
system, as well as the engine coolant
level.
• Check the air filter and have them
replaced if necessary.
• Reconnect the battery after checking
the charge status (refer to
“Maintenance-Free Battery” in this
section) and perform the initializing
procedure if applicable.
• With the transmission in N (Neutral),
let the engine idle for several
minutes.WARNING!
The engine idle must be performed
outdoors. Exhaust gases contain
carbon monoxide which is strongly
toxic and potentially lethal.

Battery Statement
Battery Statement Status of
Charge
To avoid problems with ignition and/or
the electrical system in general when
you are driving, the battery charge
status is constantly maintained and
guaranteed by the vehicle's recharge
circuit; the main component of which
is the alternator. This circuit is only
able to supply voltage to the battery
when the vehicle is traveling.
The
warning light on the
instrument cluster (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”), will
indicate any malfunctions in the
recharge circuit or an insufficient
battery charge status (flashing).
The vehicle is fitted with advanced
electronic systems, such as, for
example, the alarm system and various
electronic control modules, which
consume power even when the key in
the ignition switch is in theSTOP (OFF)
position and the vehicle is not being
used.
Therefore, it is fundamental that the
battery is properly charged to ensure
that the engine starts properly and
