Maintenance and Care
Vehicle Stored for Long
Periods
If the vehicle is going to be stored
for long period of time, you need to
check first the battery charge status.
After this check follow the below
precautions:
• Wash and dry the vehicle thoroughly.
• Store the vehicle in a covered, dry
and, if possible, ventilated area.
• Select P (Park) and turn off the
engine.
• Check that the parking brake is NOT
engaged.
• Disconnect the battery or connect a
battery charger (refer to paragraph
"Maintaining Battery Charge"
of chapter "Battery Status and
Maintenance" in this section).
• During parking, battery charge status
must be carried out every three
weeks. Recharge the battery if the
open circuit voltage is lower than
12.2 V.
• Do not empty the engine cooling
system
• Clean and protect the painted parts
applying protective wax.
• Clean and protect polished metal
parts with special products available
on the market.
• Talc the windshield wiper blades and
raise them from the windshield.
• Cover the vehicle with a long cloth in
breathable fabric (available from the
Service Network ). Do not use thick
plastic sheets, which do not allow the
humidity on the vehicle surface to
evaporate.
• Inflate the tires up to a pressure
which must be 1 bar (14.5 psi) higher
than the normally prescribed one,
and check it at regular intervals.
NOTE:
The Service Network can provide
you with any information about the
available “Indoor and Outdoor Car
Covers”, available in the “Genuine
Accessories” range.
WARNING!
The tire pressure must be brought
back to the prescribed value before
reusing the vehicle (
: chapter
"Tire Inflation Pressure" in section
"Technical Specifications").
Restarting the Vehicle
after a Long Inactivity
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 "Battery
Status and Maintenance" in this
section) and perform the initializing
procedure if applicable.
• With the gearshift in N (Neutral), let
the engine idle for several minutes.
