Driving
The control lamps light up together when the
ignition is s wit
ched on and shoul d t

-
ter approximately 2 seconds. This is the time
taken for the function check.
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
Braking and parking
Via the ESC, the XDS will brake the inside
wheel and count er the e
xcess driving t
or
que
of that wheel. This means that the requested
trajectory is much more precise.
XDS works in combination with the ESC and is
always active, even when ASR is disconnec-
ted, or when the ESC is in Sport mode or dis-
connected.
Multi-collision brake*
In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident and causing
other collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the
vehicle, as long as the accident has not dam-
aged the ESC, the brake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:
