maintenance VOLKSWAGEN TRANSPORTER 2016 Service Manual

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 .,.
Vehicle care and maintenance 399

ensure that the mobile telephone is securely at-tached to the dash panel and always within reach of the driver. Depending on which hands-free sys-tem is installed, the connection between the mobile telephone and the external aerial is established ei-ther via the telephone holder or via an existing Bluetooth® connection between the mobile tele-phone and the vehicle.
Connecting the mobile telephone is to a telephone aerial integrated in the vehicle or to an external tel-ephone aerial reduces the electromagnetic radia-tion generated by the telephone which could affect the human body. Using an aerial also improves the quality of the signal.
If a mobile telephone is used in the vehicle interior without this hands-free system, it is not safely se-cured in the vehicle and also not connected to the vehicle's external telephone aerial. Furthermore, the mobile telephone is not being charged in the telephone holder. lt is also likely that the telephone connection will be disrupted and the signal strength will be poor.
No mobile telephone should be used in the vehicle unless it is connected to a hands-free unit. Volks-wagen Commercial Vehicles recommends the use of an external aerial when a mobile telephone is used in the vehicle.

A WARNING
Any mobile telephone that Is not secured or is incorrectly secured In the vehicle could be flung though the Interior during a sudden driving or braking manoeuvre, or In the event of an accident. This could cause Injuries.
• Mobile telephones, other devices and tele-phone accessories such as telephone hold-ers, notepads and portable navigation devi-ces must always be secured properly outside of the alrbag deployment zones or be stowed In a safe place whilst the vehicle Is In motion.
400 I Cleaning and maintenance
A WARNING
If mobile telephones or two-way radios that are not connected to an external aerial are used, electromagnetic radiation In the vehicle could exceed limit values and thus be a health hazard for drivers and other vehicle occupants. This also applies to external aer-ials which have not been correctly Installed.
• Keep mobile telephone aerials at least 20 cm away from pacemakers, as the telephones may affect their functioning.
• Do not carry a mobile telephone in your breast pocket above a pacemaker when the telephone Is switched on or In standby mode.
• Switch off the mobile telephone Immedi-ately If you suspect it may be Interfering with a pacemaker.

Diesel particulate filter
r-f'n First read and observe the Introductory L-J,:,.IJ Information and safety warnings & on page 407.
The diesel particulate filter filters out soot particles in the exhaust gas. The soot particles gather in the filter and are burnt under high temperatures peri-odically (regeneration). Heat produced can warm the engine.
Regeneration can cause noises, light smells and delay in radiator fan irrespective of the outside temperature, even after the engine is switched off.
To assist the regeneration of diesel particle filter, Volkswagen recommends that you avoid making only short journeys. In vehicles with a DSG® dual clutch gearbox the engine speed can increase while the vehicle is being driven. However, the indi-cator lamp • will not light up.
Observe the following points to ensure that the ex-haust system and the diesel particulate filter will work properly for a long time:
