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

Locking the steering wheel
• When the vehicle key has been removed, turn the steering wheel slightly until you hear the lock-ing pin engage.
The steering should be locked every time you leave the vehicle to make il more difficult for the vehicle to be stolen.
Unlocking the steering wheel
• Turn the steering wheel slightly to lake the load off the steering lock mechanism. Hold the steering wheel in this position and tu m the vehicle key clockwise out of position 217 @.
A WARNING
If the power steering is not working, the steering wheel is difficult to turn, which makes it difficult to steer the vehicle.
• The power steering only functions when the engine Is running.
• Never allow the vehicle to roll if the engine is switched off.
• Never remove the vehicle key from the ig-nition lock when the vehicle is in motion. The steering lock may be activated and you will no longer be able to steer the vehicle. Power steering
With power steering, the steering assistance is au-tomatically matched to vehicle speed, the steering wheel torque and the steering wheel angle. The power steering will only function when the engine is running.
You will need considerably more strength than nor-mal to steer the vehicle if lhe power steering is re-duced or has failed completely. Starting the engine, changing gear and parking I 281
