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.
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. .,.

Storing tyres
Mark tyres before you remove them to indicate the direction of rotation. This ensures you will be able to mount them correctly when you replace them (left, right, front, rear). When removed, the wheels or tyres should be stored in a cool, dry and pref-erably dark place. Do not store tyres mounted on the rim vertically.
Any tyres not fitted on rims should be kept in suita-ble sleeves to protect against dirt and should be stored vertically (standing on the tread).
All-terrain tyres
Some vehicles can be fitted at the factory with "all-terrain tyres". These tyres have a deep-tread pro-file that alters the vehicle's driving properties (such as comfort, consumption, braking distance, corner-Ing behaviour, rolling noise)=>&.
A WARNING
Corrosive liquids and other substances can cause visible and Invisible damage to the tyres, which can cause the tyre to burst.
• Always keep chemicals, oils, lubricants, fuel, brake fluid and other corrosive substan-ces away from the tyres.
A WARNING
Old tyres (even if never used) can suddenly lose pressure or burst, especially at high speeds. This can cause accidents and seri-ous injuries.
• Avoid using tyres that are more than six years old. If you have no alternative, drive slowly and with extra care at all times.
Rims
,....-('n First read and observe the Introductory L-J.:.ll information and safety warnings & on page 367.
The design of the wheel bolts is matched to the rims. If different rims are fitted, the correct wheel bolts with the right length and correctly shaped bolt heads must be used. This ensures that wheels are fitted securely and that the brake system works properly =>page 420.
For technical reasons, it is not generally possible to use the wheels from other vehicles. This can al-so apply to wheels of the same vehicle type.
A WARNING
The deep-tread profile of all-terrain tyres can considerably increase the braking distance or cornering behaviour and thus cause acci-dents and serious injuries.
• Always bear the modified vehicle handling in mind, and drive carefully.
CD
Avoid heavy impacts and drive round obstacles whenever possible. Tyres, particularly low-pro-file tyres, can be considerably compressed and deformed by potholes and curb edges especial-ly. This can cause the tyre's webbing reinforce-ment to brake, and cause dents or rips on the side walls or deformations or cracks on the rims.
Old tyres should be disposed of as required !!IS by legislation. The tyres and rims approved by Voikswagen Com-mercial Vehicles are specially matched to the char-acteristics of the vehicle and make a major contri-bution to good road holding and safe handling.
Wheel bolts
Wheel boils must always be tightened with the cor-rect tightening torque =>page 420.
Rims with bolted-on rings
Rims with bolted-on rings consist of several com-ponents. These components are fastened using special bolts and special fastening technology. This ensures that the wheel functions proper1y, does not leak, remains safe and runs true. For this reason, damaged rims should be replaced. They may only .,..

When the spare wheel is not the same as the
other tyres mounted on the vehicle
If the spare tyre is not the same as the tyres that are mounted on the car-for example with winter tyres -only use the spare tyre for a short period of time and drive with extra care &.
Refit the normal, functional road wheel as soon as possible.
Follow these guidelines:
• Do not drive faster than 80 km/h (50 m ph).
• Avoid full acceleration, sudden braking and fast driving through bends in the road.
• The tyre pressure must be checked as soon as possible after fitting the spare wheel =>page 371.
The tyre pressure of the spare wheel should be checked together with the normal tyres, at least once a month. The spare wheel should have the highest pressure allowed for the vehicle 371.
A WARNING
Incorrect use of the spare wheel can lead to a loss of control over the vehicle, to collisions or other accidents and cause serious injuries.
• Never use a spare tyre if it is damaged or worn down to the tread wear Indicators. .,..

A WARNING (Continued)
• In some vehicles, the spare wheel could be smaller than the standard wheel. The small spare wheel has a sticker with the text "80 km/h" or "50 mph". This is the maximum speed at which you are permitted to drive with this tyre.
• Never drive faster than 80 km/h (50 mph). Do not accelerate quickly, brake suddenly or drive at high speed through bends.
• The spare wheel must always be secured firmly with the wheel bolts supplied by the factory.
