A WARNING (Continued)
• Although the brake support systems are very effective and can help to control the ve-hicle in difficult driving situations, please al-ways remember that the driving stability of the vehicle depends on the tyre grip.
• When accelerating on a slippery surface, for example on ice and snow, press the accel-erator carefully. The wheels can spin even when brake support systems are active, and this can lead to a loss of control of the vehl-cl e.
A WARNING
ESC will be considerably less effective if oth· er components and systems that affect driv-ing dynamics are not serviced correctly or are not functioning properly. This also ap-plies, but not exclusively, to the brakes, tyres and other systems that have already been named.

A WARNING (Continued)
• Please always note that modifications and changes to the vehicle can affect the function of the ABS, BAS, EDL, TCS and ESC.
• Alterations to the suspension system or the use of non-approved wheel and tyre com-binations can affect the function of ABS, BAS, TCS, EDL and ESC and reduce their ef· fectiveness.
• Suitable tyres are also crucial if ESC is to function optlmaliy =>page 367.
m The ESC and TCS can only function properly L.:U if ail 4 wheels are fitted with the same tyres. Any differences in the roiling radius of the tyres can cause the system to reduce engine power unex-pectedly.
m If there is a fault in the ABS, the ESC, TCS lU and EDL will also stop working.
m Operating noises may be heard during the L.:U self-regulation processes of the systems ex-plained above. The Electronic Stability Control (ESC) only func-tions when the engine is running. lt consists of ABS, EDL and TCS.
When the engine is running, the TCS can be switched off by pressing the@ 224 button. The TCS should only be switched off in certain sit-uations when the traction achieved is not sufficient. For example:
• When driving in deep snow or on loose surfa-ces.
• When rocking the vehicle backwards and for-wards to free it from mud.
Then press the@ 224 button to switch the TCS back on.

Brake fluid
B7E.02AO
Fig. 225 In the engine compartment: cap on the brake fluid container.
r-111 First read and observe the Introductory l-Jr:,U Information and safety warnings&. on page 269.
Brake fluid will gradually absorb water from the surrounding air. The brake system will be damaged if there is too much water in the brake fluid. The boiling point of the brake fluid is also considerably reduced by the water content. Heavy use of the brakes may cause a vapour lock in the brake sys-tem if the water content is too high. Vapour locks reduce levels of braking power, considerably in-crease braking distance and can even cause the brake system to fail completely. Your own safety and that of other road users depends on having a brake system that functions properly at all times
Brake fluid specification
Volkswagen has developed a brake fluid that has been optimised for the brake system in the vehicle. To ensure optimal operation of the brake system, Volkswagen Commercial Vehicles recommends the use of brake fluid compliant with VW stand-ard 501 14.
Before using a particular brake fluid, check that the specifications printed on the container correspond to the vehicle requirements.
Brake fluid that is compliant with VW stand-ard 501 14 is available from Volkswagen Commer-cial Vehicles dealerships.
If this brake fluid is not available and it is necessa-ry to use another high-quality brake fluid instead, brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can be used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 have the same chemical com-position. Some of these brake fluids may contain chemicals that can damage or destroy brake sys-tem components over time.
To ensure sustained optimal operation of the brake system, Volkswagen Commercial Vehicles there-fore recommends the use of brake fluid that is compliant with VW standard 501 14.
Brake fluid that is compliant with VW stand-ard 501 14 fulfils the requirements of DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
The brake fluid level must always be between the MIN and MAX marking of the brake fluid container or above the MIN marking &.
The brake fluid level cannot be checked accurately in all models as engine components may partially conceal the brake fluid container. If the brake fluid level cannot be read exactly, please go to a quali-fied workshop.
The brake fluid level drops slightly when the vehi-cle is being used as the brake pads wear and the brakes are automatically adjusted.
Changing the brake fluid
The brake fluid must be changed as indicated in the service schedule Service schedule. The brake fluid should be changed by a qualified workshop. Volkswagen Commercial Vehicles rec-ommends using a Volkswagen Commercial Vehi-cles dealership for this purpose. Only brake fluid that confonns with the required specification should be used.
A WARNING
Brake failure or reduced braking effect can be caused by the brake fluid level being too low or by brake fluid that Is too old or unsuitable.
• The brake system and brake fluid level must be checked regularly.
• The brake fluid should be changed regu-larly, according to the service schedule Service schedule.
• Heavy use of the brakes may cause a va-pour lock If the brake fluid Is left In the sys-tem for too long. Vapour locks reduce levels

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 (Continued)
