A WARNING (Continued)
• Never ignore any illuminated warning lamps or text messages.
• Stop the vehicle as soon as possible and when safe to do so.
A WARNING
Driving with poor brakes can result in acci-dents and serious injuries.

heavy load on the brakes should be avoided. For example, when driving too close to the vehicle ahead.
The rate of wear of the brake pads depends to a great extent on the conditions under which the ve-hicle is operated and the way in which the vehicle is driven. With regular urban trips, short journeys and a sporty driving style, the brake pads must be checked by a qualified workshop more regularly than stated in the service schedule.
When driving with wet brakes, for example after driving through water, after heavy rainfall or after washing the vehicle, the braking effect may be de-layed as the brake discs will be wet, or possibly ic-ed up (in winter). The brakes must be "dried" as quickly as possible by careful braking at higher speed. Ensure that no vehicle behind you or no other road user is put at risk as a result of this ac-
Any salt layer accumulating on the discs and pads will delay the braking effect and increase the braking distance. If the brakes on the vehicle have not been applied for a long time on roads that have been gritted with salt, the layer of salt must be re-duced through careful braking &.
Corrosion on the brake discs and dirt in the brake pads are facilitated through long periods of inactivi-ty, low mileage and low load levels. With inactivity or low use levels for the brake pads as well as cor-rosion, Volkswagen Commercial Vehicles recom-mends that the brake discs and brake pads be cleaned by braking strongly several times from high speed. Ensure that no vehicle behind you or no other road user is put at risk as a result of this
Fault in the brake system
A brake circuit may have failed if you have to re-duce speed and the vehicle does not brake as nor-mal (sudden increase in braking distance). This will be indicated by the warning lamp m and in some cases a text message. Go to the nearest qualified workshop immediately to have the fault corrected. Drive at low speed when doing this and anticipate much longer braking distances and an increase in the pressure required on the pedal.
Brake servo
The brake serve will only function when the engine is running and reinforces the pressure applied by the driver on the brake pedal.
If the brake serve is not functioning or the vehicle is being towed, the brake pedal will have to be de-pressed more forcefully as the braking distance will be increased due to the lack of assistance for the brake system &.
A WARNING
New brake pads will not have the optimal braking effect when first fitted.
• New brake pads cannot generate the full braking effect during the first 300 km and must first be run In. A reduced braking effect can be Increased by applying more pressure to the brake pedal.
• You must drive particularly carefully when driving with new brake pads In order to re-duce the risk of accidents, serious Injuries and loss of control of the vehicle.
• Never drive too close to other vehicles when running in new brake pads, and never create a driving situation that will place a heavy load on the brakes.
A WARNING
Overheated brakes reduce the braking effect and considerably Increase the braking dis-tance.
• When driving downhill the brakes are placed under particular strain and become hot very quickly.
• Before driving down a long, steep gradi-ent, reduce speed and change to a lower gear or move the selector lever to a lower position. This will make use of the engine braking ef-fect and relieve the load on the brakes.
• Non-standard or damaged front spoilers could restrict the airflow to the brakes and cause them to overheat.
A WARNING
Wet brakes or brakes coated with ice or road salt react more slowly and require longer braking distances.
• Carefully apply the brakes to test them.
• Always dry brakes and clean off any coat-Ing of Ice and salt with a few cautious appli-cations of the brake when visibility, weather, road and traffic conditions permit.
A WARNING
Driving without the brake servo can consider-ably Increase the braking distance and thus cause accidents and serious Injuries.
• Never allow the vehicle to roll if the engine Is switched off.

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
