situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or "lengthening" of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected.
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, which could
lead to further 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

Operation
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
● The ESC, ABS, ASR, EDS and the electronic
torque control system cannot exceed the lim-
its imposed by the laws of physics. Always
bear this in mind, especially on wet or slip-
pery roads. If you notice the systems cutting
in, you should reduce your speed immediate-
ly to suit the road and traffic conditions. Do
not be encouraged to take risks by the pres-
ence of more safety systems. If you do, an ac-
cident may occur.
Please remember that the accident risk al-
●
ways increases if you drive fast, especially 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 elec-
tronic torque control system cannot prevent
accidents: risk of accidents!
Accelerate with caution on slippery surfa-
●
ces (for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident!
Note
The ABS and ASR will only operate correctly
●
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can make noises when they intervene.
● If the warning lamp  lights up, or  alter-
›››
natively, there could be a fault
Switching on/off the ESC and ASR
The ESC is switched on automatically when
the engine is started, and only works when
the engine is running and includes the ABS,
EDS and ASR systems.
The ASR function should only be switched off
in situations in which traction is insufficient,
including:
When driving in deep snow or on surfaces
●
that are not very firm.
To "free" the vehicle if it gets stuck.
●
Then switch the ASR function back on.
