Abs - Ferrari California Owner's Manual

ABS

This is a safety device which activates to prevent wheel locking if
the driver depresses the brake pedal too sharply, especially under
poor grip conditions.
The system is composed of:
- electro-hydraulic unit
- electronic brake-force distribution EBD
- four speed sensors on the wheels, incorporated in the bearings.
- the entire ESP sensor system (steering angle sensor,
accelerometer, yaw sensor, etc.).
These features add to the vehicle's standard braking system,
without changing its characteristics.
Important note
When the ABS system is active, during emergency braking or in
poor grip conditions, a "pulsing" sensation will be felt through
the brake pedal. Hold the brake pedal down to continue the
braking action.
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.

These adjustment phases will be repeated in cycles in the event that
brakes are applied with ABS intervention, until the vehicle comes
to a stop or the pressure on the pedal decreases.
In addition, the system offers the following advantages:
- Driving stability (no skidding): even in the event of sharp braking
approaching wheel locking.
- Manoeuvrability (no side-skidding on sharp turns).
This means that even when an emergency situation requires sudden
braking, the driver can avoid obstacles, or brake on a curve, without
affecting the vehicle stability.
Warning
The ABS system features remain unaltered as long as the speed
limit for the tyre side grip is not exceeded. When this limit is
exceeded, vehicle skidding cannot be avoided.
- Optimal braking distance :
depending on the type of road surface, the braking distance may
be reduced by as much as 40%.
Warning
The ABS system does NOT exempt the driver from driving
carefully and responsibly at all times.
