Additional functions that are contractually agreed with the customer, e.g. vehicle positioning in an emergency, allow certain vehicle data to be trans-mitted from the vehicle.
Event data recorder
The vehicle is not fitted with an event data record-er.
Event data recorders temporarily store vehicle in-formation. This provides precise information in the event of an accident. In vehicles with an airbag system, data that might be relevant in the event of an accident can be stored, e.g. impact speed, belt buckle status, seat positions and trigger speed. The scope of the data is manufacturer-specific.
An event data recorder may only be fitted if the owner has approved the procedure. This is cov-ered by legislation in some countries.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions, such as lane change flash, single door unlocking and displays, can be reprogrammed using special workshop equipment. If this is the case, the de-scriptions in your vehicle wallet will no longer cor-respond with the original functions. Volkswagen Commercial Vehicles recommends that any re-programming should be confirmed in the service schedule under "Workshop comments".
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Reading the vehicle's event memory
There is a diagnostic interface for reading the event memories in the vehicle interior &. Data relating to the function and status of the electronic control units are stored in the event memory. Addi-tional information on the stored data is available from qualified workshops.
The diagnosis interface is located in the footwell on the driver side behind a cover next to the lever for opening the bonnet.
The event memory should only be read and reset by a qualified workshop.
After a fault has been rectified, the information in the memory pertaining to the fault is deleted. Other memory content is overwritten on an on-going ba-sis.
A WARNING
Incorrect use of the diagnostic Interface can cause faults, which can result in accidents and serious injuries.
• Never read the event memory using the di-agnostic Interface yourself.
• The diagnostic Interface should only be read by a qualified workshop. Using a mobile telephone in the vehicle without a connection to the

Both during telephone calls and in standby mode, mobile telephones transmit and receive radio waves, which may also be termed "high-frequency energy". Current scientific literature warns us that radio waves can be harmful to human beings if they exceed certain limits. Government bodies and international committees have introduced threshold values and guidelines to ensure that electromag-netic radiation produced by mobile telephones does not pose a hazard to health. However, there is no proven scientific evidence that demonstrates that cordless telephones are absolutely safe.
For this reason, some experts are calling for more precautions to be taken in the use of mobile tele-phones, by taking steps to reduce the level of per-sonal exposure to electromagnetic radiation.
If a mobile telephone that is not connected to the vehicle's external aerial is used inside the vehicle, the level of electromagnetic radiation could be higher than when the mobile telephone is connec-ted to an integrated aerial or any other external aerial.
If the vehicle is fitted with a suitable hands-free unit which enables the use of innumerable additional functions of Bluetooth® compatible mobile tele-phones, this will satisfy the legal requirements in many countries which permit the use of a mobile telephone in a vehicle only if a hands-free unit is used.
The factory-fitted hands-free system in your vehicle has been developed for use with mobile tele-phones that are compatible with Bluetooth®_ Mo-bile telephones must be carried in a suitable tele-phone holder or be stored securely in the vehicle. If a telephone holder is used it must be securely at-tached to the base plate. This is the only way to .,.
