• Never secure or mount objects such as drink holders or telephone holders on or next to the airbag covers or within the deployment zone of the airbag.
• Only use rim/tyre combinations which have been approved by Volkswagen Commer-cial Vehicles for your vehicle type.
Any new engine has to be run in during the first 1 ,500 kilometres. During its first few hours of run-ning, the internal friction in the engine is greater than later on when all the moving parts have bed-ded down.
The style of driving during the first 1 ,500 kilometres will also affect the engine quality. Even after this time-and especially with a cold engine-drive the .,.
vehicle at moderate speeds in order to reduce en-gine wear and to increase the mileage that the en-gine can cover. Do not drive at engine speeds that are too low. Always shift down gear if the engine is not running smoothly. The following applies up to 1,000 kilometres:
• Do not depress the accelerator fully.
• Do not drive the vehicle at more than 2/3 of the top engine speed.
• Do not drive with a trailer attached.

3961 Clt!aning and maintenance
A WARNING (Continued)
• When using products that give off harmful fumes, always work outdoors or In a well-ventilated area.
• Never use fuel, turpentine, engine oil, nail varnish remover or other volatile fluids for vehicle care. They are toxic and highly flam-mable. They could cause fires and explo-sions.
CD
• Only use suitable service fluids for refilling. Never use the wrong service fluid. Failure to observe this warning can result In serious mal-functions and engine damage.
• Optional equipment and other accessories In front of the air Inlet reduce the cooling effect of the coolant. The engine may overheat at high ambient temperatures and high engine loads.
Leaking service fluids can pollute the envi-C!IS ronment. Spilt service fluids must be collec-ted in suitable containers and disposed of properly and with respect for the environment.
Vehicles with special auxiliary equipment or body parts
The manufacturer of these components must en-sure that these parts (fittings) adhere to the stipula-ted environmental laws and regulations, particular-ly the EU directive 2000/53/EC concerning end-of-life vehicles and EU directive 2003/11/EC concern-ing the restriction on the marketing and use of cer-tain dangerous substances and preparations.
The vehicle owner should keep all assembly docu-mentation for these auxiliary fittings, and pass it on to any scrapping company later engaged. This is to facilitate environmentally responsible disposal for all vehicles, Including refitted vehicles.
Windscreen repairs
To function properly, some items of equipment re-quire a camera or sensor, which Is located on the inside of the windscreen near the interior mirror. If the windscreen in the viewing field of the camera ,..
or sensors has been damaged, e.g. by stone im-pact, the windscreen must be replaced. Repairing the crack can lead to malfunction or functional faults in the equipment.
After changing the windscreen, the camera and sensors must be set up and calibrated by a quali-fied workshop.
A WARNING
Incorrect repairs and modifications can cause functional problems and damage to the vehicle and impair the effectiveness of the driver assist systems. This can result In acci-dents and severe Injuries.
• Repairs and modifications to your vehicle should only be carried out by a qualified workshop.
Repairs and faults in the airbag system
,....,..,. First read and observe the introductory l.-Jo:-11 Information and safety warnings&. on page 394.
Repairs and modifications must always be car-ried out according to Volkswagen Commercial Vehicles specifications"*&.!
Modifications and repairs to the front bumper, the doors, the front seats, the headliner, or the body-work should be carried out by a qualified work-shop. System components and airbag system sen-sors might be fitted on these vehicle components.
If you work on the airbag system or remove and in-stall parts of the system when performing other re-pair work, parts of the airbag system may be dam-aged. The consequence may be that, in the event of an accident, the airbag inflates incorrectly or does not inflate at all.
Regulations must be observed to ensure that the effectiveness of the airbags is not reduced and that removed parts do not cause any injuries or envi-ronmental pollution. Qualified workshops are famili-ar with these requirements.
Any modifications to the vehicle's suspension could prevent the airbag system from working properly during a collision. For example, using tyre/ rim combinations which have not been approved by Volkswagen Commercial Vehicles, lowering the vehicle, making modifications to the suspension rate including work on the springs, struts and shock absorbers could cause the forces which are measured by the airbag sensors and sent to the electronic control unit to change. Some changes to the suspension could cause the forces measured by the sensors to increase. This can lead to the airbag system being triggered in collision scenarios
where it normally would not be triggered if modifi-cations to the suspension had not been made. Other modifications can cause the forces meas-ured by the sensors to decrease. therefore pre-venting the airbag system from being triggered when it should have been.
A WARNING
Incorrect repairs and modifications can cause function problems and damage to the vehicle and Impair the effectiveness of the alrbag system. This can result In accidents and serious or even fatal injuries.
• Repairs and modifications to your vehicle should only be carried out by a qualified workshop.
• Alrbag modules cannot be repaired. They must be replaced.
• Never use recycled airbag components or components that have been taken from end-of-life vehicles In your vehicle.
A WARNING
Modifications to the vehicle's suspension, in-cluding the use of unsuitable tyre/rim combi-nations, can cause the alrbag system to work differently and increase the risk of serious or fatal injuries In the event of an accident.
• Never install any components in the sus-pension system that do not have the same characteristics as the original factory-fitted components.
• Never use tyre/rim combinations that have not been approved by Volkswagen Commer-cial Vehicles.
Vehicle care and maintenance 397
Retrofitting two-way radios
.--m First read and observe the introductory L-.lc.U information and safety warnings & on page 394.
You will need an external aerial to use a two-way radio in the vehicle.
Any retrofit installation of electrical or electronic equipment in the vehicle will affect its vehicle type approval. Under certain circumstances, this can negate the type approval for the vehicle.
Volkswagen Commercial Vehicles has approved the vehicle for use with two-way radios providing the following conditions are observed:
• Correct installation of external aerial.
• A maximum transmitting power of 10 watts.
The equipment can only operate at maximum range with an external aerial.
Check first with a qualified workshop if you wish to use a two-way radio with a transmitting power of over 10 watts. Qualified workshops are familiar with the technical options for retrofitting. Volkswa-gen Commercial Vehicles recommends using a Volkswagen Commercial Vehicles dealership for this purpose.
Information stored in the control units
.--m First read and observe the introductory L-.lc.U Information and safety warnings & on page 394.
Your vehicle is factory fitted with electronic control units which are responsible for engine and gearbox management. The control units also monitor the function of the exhaust system and the airbags.
These electronic control units continuously evalu-ate data relevant to the vehicle while the vehicle is being driven. Only these data will be stored if there are any faults recorded or any deviations from the specified values. This is generally displayed by the indicator lamps on the instrument cluster.
Special units are required to read and evaluate da-ta stored in the control units.
These data are stored so that specialist workshops can diagnose and solve problems. The following data may have been stored:
• Engine and gearbox-relevant data.
• Speed.
• Direction of travel.
398 Cleaning and maintenance
Please comply with relevant legislation and the in-structions and information given in the operating manuals for radio equipment.
A WARNING
If radio equipment is not secured or not prop-erly secured in the vehicle, it could be flung though the interior during a sudden driving or braking manoeuvre, or In the event of an accident. This can cause Injuries.
• While the vehicle is in motion, always se-cure radio equipment properly outside the airbag deployment zone or stow them away safely.
A CAUTION
If you use two-way radios in the car without an external aerial, electromagnetic radiation in the vehicle could exceed limit values. This also applies to external aerials which have not been correctly installed.
• Two-way radios should only be used In the vehicle If an external aerial Is properly connected.
• Braking power.
• Seat belt monitor.
The control units never record conversations that take place in the vehicle. it is neither possible nor permitted to use the stored data to create move-ment profiles.
When the vehicle is being used, situations may arise in which the stored data (alone or in conjunc-tion with other information such as accident re-ports, vehicle damage, witness statements etc.) can become assignable to a particular person, whereby consultation of an expert and use of the expert's information may be necessary.
In vehicles with an emergency call function via a mobile telephone or other units, the current loca-tion can be transmitted. In the event of an accident in which the control units register that an airbag has been triggered, the system can automatically send out a signal. This depends on your service provider. Transmission is possible only in areas
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.
external aerial
,...--.m First read and observe the introductory L--I=>U information and safety warnings & on page 394.
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.
Bluetooth® is a registered trademark of Blue-tooth® SIG, Inc.
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.
