"Key-Less" ignition system
The F keys use a Key-less start system (see also the specific
ERRARI
warning sheet) which can be used to perform a KEY-ON switch and
then start the electric motors or the engine by simply placing the key
inside the vehicle in the vicinity of the driver zone. The dedicated ECU
recognises the vehicle key by the electronic ID code it contains. The
ENGINE START/STOP button on the steering wheel controls the KEY-
ON, KEY-OFF, ENGINE START and ENGINE STOP functions.
●
KEY-ON: to activate the vehicle system (instrument panel, air
conditioning and heating system, infotainment system, etc.),
press and quickly release the ENGINE START/STOP button on the
steering wheel.
●
KEY-OFF: to deactivate the vehicle system press the ENGINE
START/STOP button again WITHOUT pressing the brake pedal.
●
ENGINE START: to start up the electric motors or start the
engine, press down the brake pedal and press the ENGINE
START/STOP button when the vehicle is stationary.
Important note
Hold the brake pedal down while starting the engine.
●
ENGINE STOP: to deactivate the electric motors and stop the
engine if running, press the ENGINE START/STOP button when the
vehicle is stationary.
Roadside Recovery

Under normal conditions of use with the "Hybrid" mode set as default,
priority is given to switching on the rear electric motor and the engine
will remain off. Therefore, one the ENGINE START function has been
performed, the rear electric motor is operational and the vehicle is ready
to set off. This condition is displayed on the instrument panel.
In some situations, for example, when it is cold or the high voltage battery
charge level (SOC) is too low, the engine will start up.
Important note
Do not perform an ENGINE START with the charge lead connected.
If the key battery has a charge level that is only just sufficient, the vehicle
informs the driver via a pop-up on the instrument panel with a message
and recommends replacing the battery as soon as possible.
Warning
If the anti-theft system activation and central locking button
key is pressed when inside the vehicle, the ENGINE START function is
disabled. You must press the other button on the key to deactivate the
