57) If the space-saver wheel (for
versions/markets, where
provided) is used, the ABS keeps
operating. Always remember
that the space-saver wheel, being
smaller than the original wheel,
provides less grip.
ESC (Electronic
Stability Control)
SYSTEM
(for versions/markets, where provided)
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the vehicle’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses the sensors in
the vehicle to determine the trajectory
required by the driver through steering
and compares it with the real trajectory
of the vehicle. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
❒ Oversteer: occurs when the vehicle is
turning more than it should according
to the angle of the steering wheel.
❒ Understeer: occurs when the vehicle
is turning less than it should
according to the angle of the steering
wheel
The ESC system also includes the
following subsystems:
❒ Hill Holder
❒ ASR
❒ HBA
❒ ERM
❒ HDC
58) 59) 60)
SYSTEM INTERVENTION
This is signalled by the flashing of
warning light
in the instrument panel,
to inform the driver that the vehicle 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.
