LONG BATTERY INACTIVITY

Read through the paragraph BATTERY.
Whenever the vehicle remains unused for longer than
15 days, the battery needs to be recharged in order to
avoid sulphation (RECHARGING THE BATTERY).
Remove the battery (REMOVING THE BATTERY)
and store it in a cool and dry place.
In the winter, or when the vehicle is not used for some
time, periodically check the battery charge (about
once a month) so as to avoid deterioration.
Recharge the battery completely using the normal
method (RECHARGING THE BATTERY).
If the battery is not removed from the vehicle, be sure
to disconnect the cables from the terminals.
