A WARNING (Continued)
• Stop the vehicle as soon as possible and when safe to do so.
Q)
Failure to observe illuminated Indicator lamps and text messages can lead to your vehicle be-ing damaged. The engine oil used must correspond exactly to specifications.

The correct engine oil is important for the function and service life of the engine. A special high quali-ty multigrade oil has been filled at the factory and this can normally be used as an all-season oil.
If possible, only use Volkswagen-approved engine oil =>CD. To comply with the requirements of the flexible service, only use approved flexible service engine oil that complies with the corresponding VW standard =>table on page 355. The engine oils listed are multigrade high-lubricity oils.
Engine oils are constantly being developed and im-proved. Volkswagen Commercial Vehicles dealers are kept up to date with regard to any changes. Volkswagen Commercial Vehicles therefore recom-mends having engine oil changes done by a Volks-wagen Commercial Vehicles dealer.
The quality of the engine oil is not only tailored to the requirements of engines and exhaust gas treat-ment systems, but also to fuel quality. Due to the
way in which a combustion engine works, engine oil always comes into contact with combustion resi-dues and fuel, which has a knock-on effect on the ageing process of the oil.
The quality of fuels can vary greatly between indi-vidual markets and this must be taken into account when selecting the correct engine oil.
The use of engine oils compliant with the VW 504 00 und VW 507 00 specifications requires a fuel quality compliant with EN 228 (petrol) and EN 590 (diesel), or fuel of an equivalent quality. Engine oils compliant with VW 504 00 und VW 507 00 are therefore unsuitable for use in a large number of markets.

• Do not add any additional lubricants to the engine oil. Any damage caused by the use of such additives is not covered by the warranty.
• Only engine oil specifications that have been approved for use with the engine should be used. Using other engine oils can cause en-gine damage.
• Another engine oil can be used in the event of an emergency if the listed engine oils (=>table on page 355) are not available. To
