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.
e.g. temperature, rain.
As well as performing the actual control functions, these data are also used to detect and rectify
faults and help Volkswagen to improve vehicle functions. The majority of these data are temporary
and are only processed within the vehicle itself. Only a very small amount of data is stored in the
event memories or possibly on the vehicle key.
Reading out the vehicle's event memory
There is a diagnostic interface in the vehicle interior for reading out the event memories (on-board
diagnosis)
If you have service work performed on your vehicle, the technical data can be read out of the vehicle
together with the vehicle identification number by service employees, e.g. workshops, or third
parties such as breakdown services. Service work includes, for example, repairs, maintenance,
warranty work or quality assurance measures. The service workshop or third party collects,
processes and uses the data. The data document the vehicle's technical status, help in
troubleshooting and in improving quality and may be sent to Volkswagen in some cases.
Furthermore, the manufacturer is subject to legal product safety requirements. To make sure it
complies with these requirements, the manufacturer requires technical data from the vehicles.
Event memories in the vehicle can be reset by a service workshop as part of repair or service work.
The event memory should be read out and reset only by a qualified workshop. Additional
information on the stored data is available from the qualified workshop.
After a fault has been rectified, the information in the memory relating to the fault is deleted. Other
memory content is overwritten on an ongoing basis.
Event data recorder
This vehicle is equipped with an event data recorder. The main task of an event data recorder is to
record data in particular accident scenarios or accident-like situations, e.g. in the event of airbags
being triggered or a collision with an obstacle on the road. These data help in analysis of how a
vehicle system behaved in these situations. The event data recorder records data relating to driving
dynamics and the restraint system for a short period of 10 seconds or less. This information includes,
for example:
of the driver and front passenger were fastened.
These data help to obtain a better understanding of the circumstances in the situations where
accidents and injuries have occurred.
Data from driver assist systems are also recorded. In addition to information about whether the
systems were switched on or off, available only to a restricted extent or inactive, it is also possible to
determine whether these functions steered, accelerated or braked the vehicle in the above-
described situations. Depending on the vehicle equipment, these systems include the following:
