• Never park the vehicle where parts of the exhaust system can come Into contact with any Inflammable material underneath the ve-hicle, e.g. undergrowth, leaves, dry grass, split fuel.
CD
• To avoid unintentional movement when parking the vehicle, first apply the handbrake firmly and then remove your foot from the brake pedal.
• Always take care when driving in car parks with protruding kerbstones or bollards. Objects that protrude from the ground can damage the bumper and other components when parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels can touch the bollards or kerbs.
• Drive carefully through dips in the road, over driveways, ramps, kerbstones and other objects. Low-lying vehicle components such as the bumper, spoiler and parts of the running gear, engine or exhaust system could be dam-aged.
• If the handbrake Is not applied fully when the vehicle Is stationary and the brake pedal Is released when then selector lever Is in posi-tion P, the vehicle may move a few centimetres forwards or backwards. the slightly reduced braking force by applying more pressure to the brake pedal.

Fig. 226 Fuel consumption in litres per 100 km at two different outside temperatures.
r-1"'11 First read and observe the Introductory Information and safety warnings&. on page 278.
By adopting an economical driving style and antici-pating the traffic situation ahead, you can easily re-duce fuel consumption by 10-15%.
Cars use most fuel when accelerating. If you think ahead when driving, you will need to brake less and thus accelerate less. Wherever possible, let the car roll slowly to a stop, for instance when you can see that the next traffic lights are red.
Avoid short journeys
Directly after a cold start, the engine has a very high fuel consumption. The engine reaches its working temperature after a few kilometres, when fuel consumption will return to a normal level.
The engine and catalytic converter need to reach their proper working temperature in order to mini-mise fuel consumption and emissions. The out-side temperature is a key factor.
The different rates of fuel consumption for the same distance at both +20"C (+68"F) and at -10"C (+14"F) are shown in Fig. 226.
Therefore, avoid making too many short journeys and car share whenever possible.
Under the same conditions, the vehicle will use more fuel in winter than in summer.
280 I While dnvmg
Not only is it illegal in some countries to "warm up" the cold engine by running it while the vehicle is stationary, it is also technically unnecessary and a waste of fuel.
Adjust the tyre pressure
The correct tyre pressure reduces rolling resist-ance and therefore also fuel consumption.
Ensure that any new tyres purchased have opti-mum rolling resistance.
Use low viscosity engine oils
Fully synthetic low viscosity engine oils reduce fuel consumption. Low viscosity engine oils decrease frictional resistance in the engine and spread bet-ter and more quickly, especially for cold starts. They are especially effective In vehicles that make alotofshortjourneys.
Always ensure that the engine oil level is correct and that you keep to the service intervals (oil change intervals).
When buying engine oil, always make sure it com-plies with engine oil norms and has been approved by Volkswagen Commercial Vehicles.
Avoid unnecessary loads
Lighter vehicles are more economical and have lower environmental impact. An extra 100 kg, for example, can increase fuel consumption by up to 0.311100 km.
Remove all unnecessary objects and loads from the vehicle.
Remove any unnecessary special equipment and accessories
The more aerodynamic a vehicle, the lower its fuel consumption. Special equipment and accessories, such as roof carriers or bicycle carriers, make the vehicle less aerodynamic.
You should therefore remove any special equip-ment and luggage carriers that are not in use, es-pecially if you are going to be driving at high speeds.

A WARNING
The intelligent tyre monitoring system tech-nology cannot overcome the laws of physics, and functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.
• Check tyre pressures regularly and always maintain the specified tyre pressure value =>page 367. If the tyre pressure is too low, it is possible that the tyre temperature will in· crease to such an extent that the tread peels off and the tyre bursts.
• Always maintain correct cold tyre pres-sure as listed on the tyre pressure label =>page 367.
• Check tyre Inflation pressure regularly when the tyres are cold. Adjust tyre pressure in the cold tyre to the recommended tyre pressure for the tyres Installed on your vehi· cle as necessary.
• Check your tyres regularly for signs of wear or damage.
• Never exceed the top speed and load per-mitted for the fitted tyres.
CD
If valve caps are missing, the valve could be damaged. Always use valve caps that comply with the factory-fitted valve cap specifications. Always screw on valve caps fully. Do not use metal valve caps.
Indicator lamp
Under-inflated tyres will increase fuel con-W sumption and tyre wear. A higher tyre pres-sure generally reduces the fuel consumption. How-ever, the maximum tyre pressures specified by the manufacturer must always be adhered to.
m When new tyres are driven at high speeds for L!..J the first time, they can expand slightly and trigger a one-off pressure warning.
m Old tyres should only be replaced by tyres L!..J that have been approved by Volkswagen Commercial Vehicles for the vehicle type.
m Do not rely solely on the tyre monitoring sys-L!..J tern. Check your tyres regularly to ensure that they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blis-ters. Remove any objects that become embedded in the tyre tread but have not penetrated into the body of the tyre itself.
m The tyre monitoring system is adjusted for L!..J the factory-recommended tyre pressures to be found on the tyre pressure label. ro First read and observe the introductory Information and safety warnings & on page 318.

A WARNING (Continued)
-Remove the vehicle key from the igni-tion lock.
-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.
A WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries and death!
• Never short circuit the electric system. The vehicle battery could explode.
• Please note the following guidelines to help reduce the risk of an electric shock and serious Injuries while the engine is running or being started:
-Never touch the electrical wiring of the Ignition system.
A WARNING
There are rotating components in the engine compartment that can cause serious injury.
• Never place your hand near these compo-nents or In the radiator fan. Touching the ro-tary blades can result in serious injuries. The fan Is temperature-controlled and can start automatically, even if the engine has been switched off and the vehicle key has been re-moved from the ignition lock.
• If any work has to be performed when the engine Is started or with the engine running, there is an additional, potentially fatal, safety risk from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always be particularly careful.
A WARNING (Continued)
-Always ensure that no body parts, jew-ellery, ties, loose items of clothing or long hair can be caught up in rotating engine components. Before starting work, re-move any jewellery and ties, tie up long hair and pull clothes In tightly to avoid them getting caught In the engine com-partment.
-Always depress the accelerator careful-ly and never without due consideration. The vehicle can start to move even if the handbrake is applied.
• Always ensure that you have not left any objects, such as cleaning cloths and tools, in the engine compartment. Any forgotten items can cause malfunctions, engine damage and fires.
A WARNING
Additional insulating materials such as cov-ers in the engine compartment could disrupt the operation of the engine, cause damage and lead to severe Injuries.
• Never cover the engine with any Insulating materials.
A WARNING
Service fluids and some materials In the en-glne compartment are highly flammable and can cause fires and serious Injuries!
• Never smoke while working on the vehl-cl e.
• Never work near naked flames or sparks .
• Never spill fluids onto the engine. They could Ignite on hot engine components and hence cause injuries.
• Please note the following when carrying out any work on the fuel system or the elec-trlcal system:
-Always disconnect the vehicle battery. Ensure that the vehicle Is unlocked when the vehicle battery Is disconnected as oth-erwlse the anti-theft alarm will be activa-ted.
-Never work in the direct proximity of heating systems, water heaters or any oth-er open flames.
• Always have a fully functional and tested fire extinguisher to hand.

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 .,..
