...--m First read and observe the introductory l-.W.I Information and safety warnings&,. on page 367.
Damage to tyres and rims is often not readily visi-ble. Any unusual vibrations or signs that the car is pulling to one side may indicate that one of the tyres is damaged =:. &,..
• Reduce your speed immediately if you suspect that a wheel is damaged.
• Check the tyres and rims for damage.
• If the tyre is damaged, do not drive on. Seek expert assistance.
• If there is no visible damage, drive slowly and cautiously to the next qualified workshop in order to have the vehicle checked.
Foreign bodies in the tyre
• Leave the foreign body in the tyre if it has en-tered the inner tyre. However, foreign bodies that are stuck between the tyre tread blocks can be re-moved.
• For vehicles with a spare wheel: where appro-priate, change the damaged wheel =:>page 420 If required, seek expert assistance when changing the damaged wheel. Volkswagen Commercial Ve-hicles recommends using a Volkswagen Commer-cial Vehicles dealership for this purpose.
• For vehicles with a breakdown set: the tyre can be sealed and pumped up using the tools in the breakdown set =:.page 425. Go to a qualified workshop. Volkswagen Commercial Vehicles rec-ommends using a Volkswagen Commercial Vehi-cles dealership for this purpose.
Tyre wear
The tyre wear is affected by several factors, for ex-ample:
• Driving style.
• Unbalanced wheels.
• Running gear setting.
Driving style-fast cornering, heavy acceleration and hard braking all increase tyre wear. The run-ning gear should be checked by a qualified work-shop if the tyres show excessive wear despite a normal driving style.
Unbalanced wheels -the wheels on new vehicles are balanced. However, various factors encoun-tered in normal driving can cause them to become unbalanced, which results in steering vibration. Un-balanced wheels will affect levels of wear on the steering system and the suspension. In this case the wheels should be balanced again. New tyres have to be balanced after fitting.
Running gear setting-incorrect wheel alignment causes excessive tyre wear, impairing the safety of the vehicle. The wheel alignment should be checked by a qualified workshop if tyres show ex-cessive wear.
A WARNING
If you notice unusual vibration or the car pull-Ing to one side while the vehicle is In motion, this may indicate that one of the tyres is dam-aged.
• Reduce speed immediately and park the vehicle without obstructing traffic.
• Check the tyres and rims for damage.
• Never drive on if wheels or tyres are dam-aged. Seek expert assistance Instead.
• If there Is no visible damage, drive slowly and cautiously to the next qualified workshop In order to have the vehicle checked. Wheels and tyres 373

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.
Accessories and replacement parts
r-1'11 First read and observe the introductory l-J,:::JJ information and safety warnings & on page 394.
Volkswagen Commercial Vehicles recommends that you seek advice from a Volkswagen Commer-cial Vehicles dealership before purchasing acces-sories, spare parts or service fluids. For example, if the vehicle is to be retrofitted with accessories or if parts have to be renewed. Volkswagen Commer-cial Vehicle dealerships can recommend accesso-ries, parts and service fluids which are suitable for your requirements. They can also answer any questions you might have regarding official regula-tions.
Volkswagen Commercial Vehicles recommends you use only approved Volkswagen accessories and Volkswagen Genuine Parts®. These parts and accessories have been specially tested by Volkswagen Commercial Vehicles for suitability, re-liability and safety. A Volkswagen Commercial Ve-hicles dealership is also qualified for correct instal-lation.
Although the market is constantly scrutinised, Volkswagen Commercial Vehicles cannot assume responsibility for the reliability, safety and suitability of products Volkswagen Commercial Vehicles has not approved. Volkswagen Commercial Vehi-cles can therefore assume no responsibility for these parts, even if they have been approved by an official testing agency or are covered by an offi-cial approval certificate.
Service fluids and consumables

Any retro-fitted equipment which has a direct ef-fect on the vehicle and/or the way it is driven must be approved by Volkswagen Commercial Vehicles for use in your vehicle and bear the e mark (the European Union's authorization symbol). These devices include cruise control systems or an elec-tronically controlled suspension.
Any additional electrical components fitted that do not serve to control the vehicle itself must bear the ,A WARNING
Incorrectly performed repairs or modifica-tions to your vehicle can impair the effective-ness of the airbags, cause faults, accidents and fatal injury.
• Never secure or mount objects such as drink holders, telephone holders either on or next to the airbag covers or within the de-ployment zone of the airbag.
• Objects either on or next to the airbag module covers or are in the deployment zone of the airbags can cause serious or even fatal injuries should the airbags be activated.

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
