Braking and parking
Via the ESC, the XDS will brake the inside
wheel and count
er the e
x
cess 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:
●
When the driver presses the accelerator,
the automatic braking does not take place.
●
When the braking pressure through press-
ing the brake pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
●
Multi-collision braking will not be available
if ESC is malfunctioning.
WARNING
Driving at high speed on icy, slippery wet
ground can result in loss of vehicl
e control
and serious injury to the driver and passen-
gers.
●
The ESC, ABS, ASR, EDS and the electron-
ic torque control system cannot exceed the
limits imposed by the laws of physics. Al-
ways bear this in mind, especially on wet or
slippery roads. If you notice the systems
cutting in, you should reduce your speed
immediately to suit the road and traffic
conditions. Do not be encouraged to take
risks by the presence of more safety sys-
tems. If you do, an accident may occur.
●
Please remember that the accident risk
always increases if you drive fast, espe-
cially in corners or on a slippery road, or if
you follow too close behind the vehicle in
front of you. The ESC, ABS, brake assist,
EDS and the electronic torque control sys-
tem cannot prevent accidents: risk of acci-
dents!
●
Accelerate with caution on slippery sur-
faces (for example, icy or snow-covered).
Despite the control systems, the driven
wheels could spin, affecting the stability of
the vehicle: risk of accident!
Note
●
The ABS and ASR will only operate cor-
rectly if the f
our wheels have identical
tyres. Any differences in the rolling radius
of the tyres can cause the system to re-
duce engine power when this is not desired.
●
The regulating processes of the systems
can make noises due to their operation.
●
If the warning lamp or lights up,
there could be a fault

page 82.
●
Any modifications made to the vehicle
(for example, to the engine, brake system,
running gear or to the combination of
wheels and tyres) may affect the operation
of the ABS, ASR and EDS.
Connecting and disconnecting the
ESC and ASR*
The ESC is switched on automatically when
the engine is st
art
ed, and only w
orks when
the engine is running and includes the ABS,
EDS and ASR syst
ems.
The ASR function shoul
d only be switched off
in situations in which traction is insufficient.
Depending on the finishes and versions, there
is the possibility of disconnecting only the
ASR or activating the ESC in “Sport” mode.
