Operation Manual

ESC (Electronic Stability Control)
SYSTEM
This is an electronic system that controls car stability
in the event of tyre grip loss, helping maintain
directional control.
The system is capable of recognising potentially
dangerous situations in terms of the stability and
intervenes automatically on the brakes in a
differentiated manner for the four wheels in order to
provide a stabilising torque.
The ESC system also includes the following
subsystems:
❒ HH (Hill Holder)
❒ ASR (AntiSpin Regulation)
❒ HBA (Hydraulic Brake Assistance)
SYSTEM INTERVENTION
This is indicated by the flashing of the
warning
light on the instrument panel, to inform the driver
that the car is in critical stability and grip conditions.
SYSTEM ACTIVATION
The ESC system switches on automatically when the
engine is started and cannot be switched off.
HH (Hill Holder) SYSTEM
This is an integral part of the ESC system and
facilitates starting on slopes, activating automatically
in the following cases:
❒ uphill - car stationary on a road with a gradient
higher than 5%, engine running, brake pressed
and transmission in neutral or gear other than
reverse engaged;
❒ downhill - car stationary on a road with a
gradient higher than 5%, engine running, brake
pressed and reverse gear engaged.
When setting off, the ESC system control unit
maintains the braking pressure on the wheels until
the engine torque necessary for starting is reached,
or in any case for a maximum of 2 seconds, allowing
your right foot to be moved easily from the brake
pedal to the accelerator.
When two seconds have elapsed, without starting,
the system is automatically deactivated, gradually
releasing the braking pressure.
During this release stage it is possible to hear a
typical mechanical brake release noise, indicating the
imminent movement of the car.
WARNING
The HH system is not a parking brake;
therefore, never leave the car without
having engaged the handbrake, turned the
engine off and engaged first gear, so that it is
parked in safe conditions (for further
information read the "Parking" paragraph in the
"Starting and driving" chapter).
