Driving
If the running gear or brake system is modi-
fied, the effectiveness of the ABS could be
severely limited.
Hydraulic Brake Assist (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction con-
trol system reduces the engine torque to
match the amount of grip available. This
helps the car to start moving, accelerate or
climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is ac-
tive up to approximately 100 km/h (62 mph).
To prevent the disc brake of the braked
wheel from overheating, the EDL cuts out
automatically if subjected to excessive loads.
The 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 engine torque management
(XDS)
When taking a curve, the driveshaft differen-
tial 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) re-
ceives less drive torque than the inner wheel.
This may mean that in certain situations the
torque delivered to the inner wheel is too
high, causing the wheels to spin. On the oth-
er hand, the outer wheel is receiving a lower
drive torque than it could transmit. This can
cause a loss of grip on the drive axle, in this
case the front axle, which results in under-
steer or “lengthening” of the trajectory.
The XDS 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 requested
trajectory is much more precise.
XDS works in combination with the ESC and
is always active, even when ASR is discon-
nected, or when the ESC is 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 and causing
other collisions.
The multi-collision brake works for front,
side or rear accidents, when the airbag con-
trol unit records its activation level and the
accident 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 damaged the ESC, the brake hy-
draulics or the on-board network
The following actions control automatic
braking 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.
