• 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.
The vehicle may consume up to 1.0 litre of engine oil per 2,000 km, depending on how you drive and the conditions in which the car is used. In new ve-
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. .,.

Fig. 280 How to swap wheels.
.....-r'n First read and observe the introductory L-W! Information and safety warnings & on page 367.
The tyres are the most used and most underesti-mated parts of a vehicle. Tyres are very important as the narrow tyre surfaces are the only contact between the vehicle and the road.
The service life of tyres is dependent on tyre pres-sure, driving style handling and fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The tyres and rims approved by Volkswagen Commercial Vehicles are specially matched to the characteristics of the vehicle and make a major contribution to good road holding and safe handling.
Avoiding damage to the tyres
• If you have to drive over a kerb or similar obsta-cle, drive slowly and at a right angle if possible.
• Inspect the tyres regularly for damage such as cuts. cracks or blisters.
• Remove foreign objects that are in the outer tyre tread and have not penetrated the Inner tyre 373.
• Always respond to any warning messages giv-en by the tyre monitoring system=:opage 318.
• Damaged or worn tyres must be replaced im-mediately =:o page 373.
• Regularly check the tyres for hidden damage =:-page 373.
368 Cleaning and maintenance
• Never exceed the top speed and load permitted for the tyres that are fitted =:o page 375.
• Protect the wheels, including the spare wheel, from contact with corrosive substances, including oils, lubricants, fuel and brake fluid =:o &.
• Replace missing dust caps immediately.
Tyres with directional tread pattern
Tyres with directional tread pattern have been de-veloped to roll in one direction only. An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread =:o page 375. The di-rection of rotation must be adhered to. This is the only guarantee for optimum grip and helps to avoid aquaplaning, excessive noise and wear.
If, however, the tyre is fitted in the opposite direc-tion to the tread pattern, you must take more care when driving as the tyre is now no longer being used according to its designation. This is particu-larly important on wet roads. The tyres must be re-placed as quickly as possible or be fitted with the tread in the correct direction.
Rotating wheels front to rear
Regularly rotating the wheels as shown in the illus-tration =:o Fig. 280 is recommended to help ensure that tyres wear evenly. All the tyres will then last for about the same time.
Volkswagen Commercial Vehicles recommends having the wheels changed by a qualified work-shop.
Tyres that are older than 6 years
Tyres age through physical and chemical process-es that can impair their function. Tyres that are stored unused for an extended period will harden and become brittle more quickly than tyres which are in constant use.
Volkswagen Commercial Vehicles recommends re-placing tyres that are more than 6 years old with new tyres. This also applies for tyres, including the spare wheel, which appear to still be in good con-dition and whose tread depth has not yet reached the minimum value stipulated by legislation =:o &.
The age of a tyre can be determined from the man-ufacturing date, which Is a component of the tyre identification number (TIN) =:o page 375. .,..

A WARNING (Continued)
• Check tyre pressures regularly, at least once a month, and before every long journey.
• All tyres must have the correct tyre pres-sure to suit the vehicle load.
• Never reduce excess pressure when the tyres are warm.
CD
• When attaching the tyre pressure gauge make sure that you do not position it at an an-gle to the valve shaft. This can damage the tyre valve.
Tread depth and wear indicators
Fig. 281 Tread wear indicator.
r-fl1 First read and observe the Introductory L-.lo:::.l.l Information and safety warnings & on page 367.
Tread depth
Difficult driving situations demand the deepest pos-sible tread depth for the tyres and the same tread depth for the tyres on the front and rear axles. This applies in particular for driving in winter weather and cold temperatures and in wet conditions=>&.
In most countries, the minimum tread depth re-quired by law is 1.6 mm (measured in the tread grooves next to the tread wear indicators). Ob-serve any country-specific legal requirements.
Winter tyres lose a large degree of their effective-ness when the tread is worn down to a depth of 4mm.
3721 Cleaning and maintenance
CD
• Missing valve caps, or valve caps that are not suitable or not screwed on properly, can cause damage to the tyre valve. Always use valve caps that comply with the factory-fitted valve cap specifications. Always screw on valve caps fully.
Under-infiated tyres can contribute to an in-I!IS crease in fuel consumption.
m If the tyre monitoring display warns that the W tyre pressure in at least one tyre is too low, check tyre pressures with a functioning tyre pres-sure tester. Low tyre pressure cannot be deter-mined exclusively by looking at the tyre. This also applies to tyres with a low profile.
m Please refer to the special points of the tyre W monitoring system when checking tyre pres-sures =>page 318. The tread depth of new tyres can vary according to type and manufacturer due to construction and tread design.
Tread wear indicator in tyres
The original tyres on your vehicle have 1.6 mm high tread wear indicators running across the tread =>Fig. 281. These wear indicators are positioned at set intervals around the tyre. Markings on the tyre sidewall (for instance the letters "TWI" or other symbols) indicate the positions of the tread wear indicators.
The tread wear indicators show if a tyre is worn down. The tyre must be replaced at the latest when the tread depth is just down to the tread wear indicator.
A WARNING
Worn tyres are a safety risk and can lead to a loss of control of the vehicle and cause seri-ous Injury.
• Tyres must be replaced at the latest when the tread Is worn down to the tread wear Indi-cators.
• Worn tyres have considerably less tread, particularly on wet roads, which can cause the vehicle to glide along the road surface (aquaplaning).

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:
the nearest qualified workshop. If this happens, un-bumt fuel can enter the exhaust system and es-cape into the atmosphere. The catalytic converter can also be damaged by overheating.
Even when the exhaust purification system is W working perfectly, there may be a smell of sulphur from the exhaust in some conditions. This depends on the sulphur content of the fuel being used. <1
• Only use diesel with low sulphur levels 343.
• Never use biodiesel, petrol or heating oil.
• Do not allow the fuel tank to run empty.
• Do not overfill engine oil 353.
• Do not tow-start the vehicle. Use jump leads =page 443.
