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

A WARNING (Continued)
• If engine oil is spilt on cold engine parts it can heat up and Ignite when the engine Is running.
• Always ensure that the engine oil filler cap Is securely tightened after refilling, and that the dipstick Is properly Inserted back Into the guide tube. This will prevent the engine oil from draining out on to hot engine compo-nents when the engine Is running.
CD
• Do not start the engine if the engine oil level Is above area@. Seek expert assistance. The catalytic converter and the engine could other-wise be damaged.
• When refilling or changing service fluids, please ensure that the correct fluids are added through the correct openings. Incorrect service fluids can cause serious functional problems and engine damage.
Engine oil consumption
n"'n First read and observe the introductory l.-J,:.ll information and safety warnings & on page 353.
Engine oil consumption can vary from engine to engine and can change during the working life of an engine.

Changing engine oil
n"'n First read and observe the Introductory l.-J,:.ll Information and safety warnings & on page 353.
The engine oil must be changed regularly in ac-cordance with the data given in the service sched-ule.
The engine oil and filter change should be carried out by a qualified workshop due to the special tools and knowledge required, this also applies to the disposal of used oil. Volkswagen Commercial Vehi-cles recommends using a Volkswagen Commercial Vehicles dealership for this purpose.
The engine oil level must never be above I!!S area @. Otherwise oil can be drawn in through the crankcase breather and escape into the atmosphere via the exhaust system. <1
hicles. consumption is likely to be higher for the first 5,000 km. The engine oil level must therefore be checked at regular intervals, preferably when refuelling and before long journeys.
When the engine is working hard the oil level must be kept within area =>Fig. 274 @,for instance dur-ing long motorway cruising in summer, trailer tow-ing or climbing mountain passes. <1
More details on the service intervals can be found in the service schedule.
Additives in the engine oil can cause new engine oil to discolour quickly. This is normal and does not mean that the engine oil should be changed more frequently.
A WARNING
If, In exceptional cases, you have to carry out an oil change yourself, please note the fol-lowing:
• Always wear eye protection. .,.
In the engine compartment 357

A WARNING (Continued)
• Always allow the engine to cool down completely to avoid burns.
• Avoid raising your arms when removing the oil drain plug with your fingers to help prevent oil from running down your arm.
• Use a suitable container when draining the used oil. it must be at least large enough to hold the entire quantity of engine oil re-quired for refilling.
• Never store engine oil in empty food con-tainers, bottles or any other non-original con-tainers as people finding these containers may not know that they contain engine oil.

A WARNING (Continued)
• Engine oil is toxic and must be stored out of the reach of children.
r:Q:.. Before changing the engine oil, first find out W where old oil can be disposed of properly near you.
Used oil must be disposed of in accordance W with regulations governing the protection of the environment. Never dispose of old oil in loca-tions such as gardens, woods, sewerage systems, on streets and roads, or in rivers and waterways. A WARNING
Engine coolant is poisonous and can cause serious Injuries.
• Engine coolant should only be kept in sealed original containers In a safe place.
• Never store engine coolant In empty food containers, bottles or any other non-original containers as people finding these containers may then drink the engine coolant.
• The engine coolant must be stored out of the reach of children.
• Please note that the amount of correct coolant additive used must be sufficient for the lowest ambient temperature that you ex-pect the vehicle to be exposed to.
• Coolant can freeze at extremely cold out-side temperatures, causing the vehicle to break down. Vehicle occupants with Inade-quate winter clothing could then freeze to death as the heating will also no longer func-tion.
Coolant and coolant additives can pollute the W environment. Spilt service fluids must be col-lected then disposed of properly and in an environ-mentally responsible way.

Coolant specification
r-l"'n First read and observe the Introductory l..-J,::,U Information and safety warnings & on page 358.
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40% coolant additive G 13 (fl-VW 774 J). The coolant additive is dyed purple. This mixture of wa-ter and coolant additive gives the necessary frost protection down to -2s•c (-13.F) and protects the alloy parts of the cooling system against corrosion. The mixture also prevents scaling and raises the boiling point of the coolant.
In order to protect the coolant system, the propor-tion of coolant additive must always be at least 40%, even if anti-freeze is not required in warm weather and warm climates.
If greater frost protection is required in very cold climates, the proportion of anti-freeze additive can be increased. However, the percentage of coolant additive should not exceed 60%, as this would re-duce the frost protection and the cooling effect.
When refilling the coolant, a mixture of distilled water and at least 40% coolant additive G 13 or G 12 plus-plus (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain the optimum corrosion protection =>(]). Mixing G 13 with the coolant additives G 12 plus (Tl-VW774 F), G 12 (dyed red) orG 11 (dyed blue-green) will significantly decrease the level of corro-sion protection and should therefore be avoided => A WARNING
Insufficient anti-freeze In the coolant system can cause the engine to break down and cause serious Injuries.
• Please note that the amount of correct coolant additive used must be sufficient for the lowest ambient temperature that you ex-pect the vehicle to be exposed to.
• Coolant can freeze at extremely cold out-side temperatures, causing the vehicle to break down. Vehicle occupants with Inade-quate winter clothing could then freeze to death as the heating will also no longer func-tion.
360 I Cleaning and maintenance
CD
Never mix genuine coolant additives with other coolants that have not been approved by Volks-wagen. Mixing other coolants could cause seri-ous damage to the engine and cooling system.
• If the liquid in the coolant expansion tank is brown instead of purple, for example, G 13 has been mixed with another unsuitable engine coolant. The coolant must be changed as soon as possible if this Is the case. Failure to ob-serve this point can result In serious faults or engine damage.
Coolant and coolant additives can pollute the "7!1:5 environment. Spilt service fluids must be col-lected then disposed of properly and in an environ-mentally responsible way.

A WARNING (Continued)
-Always keep children away from the en-gine compartment and never leave the ve-hicle unattended.
• The engine cooling system is under pres-sure when the engine is hot. Never open the cap of the coolant expansion tank when the engine is hot. Coolant may spray out and cause serious burns and other injuries.
-Turn the cap slowly and very carefully anti-clockwise while exerting gentle down-ward pressure on the cap.
-Always protect the face, hands and arms from hot coolant or steam with a large, thick cloth.
• When refilling, do not spill any service flu-ids on engine components or on the exhaust system. The spilt service fluids can start a fire. In certain circumstances, the ethylene glycol in the engine can catch fire.
