Fuel Inertia Switch; Abs And Ebd - Ferrari Portofino Manual

Fuel inertia switch

The fuel inertia switch is a safety device which deactivates the fuel pump
relays if a collision occurs.
A symbol appears on the left TFT display and the hazard warning lights
come on to indicate that the switch has been activated.
When the fuel inertia switch is activated, the doors are also unlocked (if
locked) and the central dome light comes on.
Warning
The fuel pump relays can be reactivated by pressing button A on the
floor in front of the driver's seat.

ABS and EBD

The ABS system is a safety device which activates to prevent wheel
locking if the driver presses the brake pedal too sharply, especially under
low grip conditions.
The system is composed of:

A
●
electrohydraulic unit
●
electronic brake force distribution EBD
●
four speed sensors on wheels
●
the entire ESP sensor system (steering angle sensor, accelerometer,
yaw sensor, etc.)
These features work in addition to the vehicle's standard braking system,
without altering its basic characteristics
Important note
When the ABS system is active, during emergency braking or in low
grip conditions, a "pulsing" sensation will be felt through the brake
pedal. Keep the brake pedal depressed to continue braking
When one of the wheels starts locking, the hydraulic control unit controls
the braking circuit by running a 3-phase cycle:
●
reduction (if necessary)
●
maintenance
●
pressure increase in the hydraulic circuit
In the event of ABS activation under braking, these regulation cycles will
be repeated until the car comes to a stop or pressure on the brake pedal is
reduced.
In addition, the system offers the following advantages:
