Battery master switch
The car is equipped with a battery master switch C located behind
the flap B. The battery master switch may only be used by Ferrari
Service Network personnel.
Disconnecting the battery
- Before disconnecting the battery, deactivate the electronic alarm with
the remote control (see page 10).
Never disconnect the battery from the electrical system when the engine is running.
Before disconnecting the battery, lower the side windows by at least 2-3 cm
(0.78-1.18 in.) to avoid damaging the weather strips when opening and
closing the doors.
When the battery is connected and fully charged, this operation is done
automatically whenever the doors are opened or closed. The windows must
remain lowered until the recharged battery is reconnected. If the battery is
discharged and the windows are fully up, only open the doors when strictly
necessary and being extremely careful; do not close them again until the
windows can be lowered.
Preferably connect to a battery conditioner if the car is not used for prolonged
periods.
Refer to the section on "If the vehicle is stored for long periods" in the "Checks
and maintenance" chapter.
