Brake assist systems Electronic Stability Control (ESC)*
The ESC helps to improv
e saf

ety. It reduces
the tendency to skid and improves the stabili-
ty and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening !.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (ASR), electronic dif-
ferential lock (EDS), electronic torque control
(XDS).
ESC also helps stabilise the vehicle by
changing the torque.
The ASR can be deactivated when wheel spin
is desirable
