EDL brakes a spinning wheel automatically and distributes the drive force to the other drive wheels.
The EDL switches off automatically under unusually heavy loads to prevent the brake from
overheating. The EDL switches back on again automatically as soon as the brake has cooled down.
XDS improves traction in order to keep the vehicle on its intended course.
Automatic Post-Collision Braking System
In the event of a collision, the Automatic Post-Collision Braking System can help the driver to reduce
the risk of skidding, and the danger of secondary collisions, through automatic braking.
The Automatic Post-Collision Braking System functions only for collisions that are detected as a
collision by the airbag control unit.
The vehicle is braked automatically if the required systems have not been damaged in the collision
and have remained functional.
The following actions override automatic braking in the event of a collision:
When the driver depresses the accelerator.
When the brake pressure transmitted through the depressed brake pedal is greater than the brake
pressure provided by the system.
WARNING
The intelligent technology used in brake support systems cannot overcome the laws of physics, and
functions only within the limits of the systems. Driving fast on icy, slippery or wet roads can lead to a
loss of control of the vehicle and could cause serious injury to the driver and passengers.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions. Do
not let the extra safety afforded by the brake support systems ABS, BAS, EDL, TCS and ESC tempt you
into taking any risks when driving.
The brake support systems cannot overcome the laws of physics. Slippery and wet roads will remain
dangerous, even when the ESC and other systems are active.
Driving too fast on wet roads can cause the wheels to lose contact with the road surface and
aquaplane. The vehicle cannot be braked, steered or controlled once it has lost contact with the
road surface.
Brake support systems cannot prevent an accident if, for example, you are driving too close to the
vehicle in front or are driving too fast for the individual situation.
Although the brake support systems are very effective and can help to control the vehicle in difficult
driving situations, please always remember that the driving stability of the vehicle depends on the
tyre grip.
wheels can spin even when brake support systems are active, and this can lead to a loss of control of
the vehicle.
WARNING
The effectiveness of ESC can be reduced considerably if other components and systems which affect
driving dynamics are not serviced properly or are not functioning properly. This also applies, but not
exclusively, to the brakes, tyres and other named systems.
Please always bear in mind that modifications and changes to the vehicle can affect the way brake
support systems operate.
Alterations to the suspension or the use of non-approved wheel and tyre combinations can affect
the function of brake support systems and reduce their effectiveness.
Suitable tyres support the effectiveness of ESC.
WARNING
Driving without the brake servo can considerably increase the braking distance and thus cause
accidents and serious injuries.
Never switch the engine or ignition off while the vehicle is in motion.
If the brake servo does not function or the vehicle is being towed, the brake pedal will have to be
depressed more forcefully as the braking distance will be increased due to the lack of assistance for
the brake system.
Switching the TCS on and off
Switch off the traction control system (TCS) if the vehicle does not have sufficient traction:
When driving in deep snow or on loose surfaces.
When rocking the vehicle free if it is stuck.
Then switch on TCS again.
Switching TCS on and off
TCS can be switched off and on in the Infotainment system Infotainment system controls and
displays
When the TCS is switched off, the yellow indicator lamp lights up on the instrument cluster
display.
As soon as the TCS starts regulating, the indicator lamp flashes yellow.
