vehicle can still be driven. The EDL will switch
on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In this
way, the wheel that is turning faster (outer
wheel) receives less drive torque than the in-
ner wheel. This may mean that in certain sit-
uations the torque delivered to the inner
wheel is too high, causing the wheels to spin.
On the other hand, the outer wheel is receiv-
ing 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
Start and driving
of that wheel. This means that the driver's de-
sired 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
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 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 four 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 when they intervene.
