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.
Starting the engine, changing gear and parking 273

A WARNING (Continued)
• If the brake servo does not function or the vehicle is being towed, the brake pedal will have to be depressed more forcefully as the braking distance will be Increased due to the lack of assistance for the brake system.
CD
• Never let the brakes "rub" by applying light pressure to the brake when it is not necessary to brake. Continual pressure on the brake pedal will overheat the brakes. This can considerably reduce the brake effect, increase the braking distance and, In certain circumstances, cause the brake system to fail completely.
Brake support systems
r-f'n First read and observe the Introductory l..-Wl information and safety warnings&. on page 269.
The brake support systems ESC, ABS, BAS, TCS and EDL only function when the engine is running. They make a considerable contribution to active driving safety.
Electronic stability control (ESC)
The ESC helps to reduce the risk of skidding and to improve driving stability by braking individual wheels in certain driving situations. The ESC de-tects critical driving situations such as oversteer, understeer and wheelspin. The system helps to stabilise the vehicle through targeted application of the brakes or by reducing engine torque.
ESC has its limitations. lt is important to realise that ESC cannot overcome the laws of physics. ESC will not be able to assist in every situation faced by a driver. For example, ESC will not be able to assist every time that there is a sudden change in the road surface quality. If a section of dry road is suddenly covered with water, mud or snow, ESC will not be able to assist in the same manner as on a dry road. If the vehicle aquaplanes (drives on a layer of water rather than on the road surface), ESC will not be able to assist in steering the vehicle as the contact to the road surface has been interrupted and it is therefore no longer pos-sible to steer or brake the vehicle. When driving at speed through bends, particularly on stretches of road with many bends, the ESC will not always be able to process complicated driving situations as
2741 While dnvang
• Before driving down a long, steep gradient, 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 effect and relieve the load on the brakes. The brakes could otherwise overheat and possibly fall. The brakes should only be used to slow or stop the vehicle.
m If the front brake pads are tested, the rear L!..J brake pads should be tested at the same time. Regularly check the thickness of the brake pads through the openings in the rims or from the underside of the vehicle. If necessary, remove the wheels to carry out a comprehensive check. Volks-wagen Commercial Vehicles recommends using a Volkswagen Commercial Vehicles dealership for this purpose. effectively as at lower speeds. When towing a trail-er, ESC is unable to assist the driver in regaining control over the vehicle.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions. ESC cannot defy the laws of motion, improve the availa-ble power output, or keep the vehicle on the road if insufficient care and attention on the part of the driver causes the vehicle to leave the road. In-stead, the ESC improves the chances of keeping the vehicle under control and, in extreme on-road driving situations, exploits the driver's steering in-put to keep the vehicle travelling in the desired di-rection. If the vehicle is driving at a speed that leads it to leave the road before the ESC can pro-vide any kind of support, the ESC will be unable to provide any assistance.
The ASS, BAS, TCS and EDL systems are integra-ted into the ESC. The ESC is always on. If the trac-tion achieved in certain situations is not sufficient, TCS can be switched off by pressing the ASR (TCS) button =>Fig. 224. Always ensure that ASR (TCS) is switched back on again once traction is sufficient.
Automatic Post-Collision Braking System
In the event of an accident, the Automatic Post-Collision Braking System can help the driver to re-duce the risk of skidding, and the danger of secon-dary collisions, through automatic braking.

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

• Supplementary heaters (auxiliary air heater or auxiliary coolant heater) 332
• Cleaning and caring for the vehicle exterior 380
A WARNING
Poor visibility through all windows increases the risk of collisions and accidents, which can cause serious injuries.
• Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
3221 While driving
A WARNING (Continued)
• Maximum heat output, which Is needed to defrost the windows as quickly as possible, is only available when the engine has reached Its operating temperature. Do not start your journey until you have good visibil-Ity.
• Always ensure that the heating and fresh air system or the air conditioning system and the rear window heating are used correctly so that you have good visibility.
• Never use the air reclrculatlon mode for an extended period. If the cooling system Is switched off, the windows can mist up very quickly In air reclrculatlon mode and reduce visibility considerably.
• Always switch off the air reclrculatlon mode when it Is not required.
A WARNING
Stale air can quickly make the driver tired and affect their concentration, which In turn can cause collisions, accidents and serious Inju-ries.
• Never switch off the blowers or switch on the air recirculatlon mode for an extended pe· riod as this prevents fresh air from entering the vehicle interior.
• Switch off the air conditioning system if you suspect that it has been damaged. This can help to prevent secondary damage. The air conditioning system should be checked by a qualified workshop.
• Repairs to the air conditioning system re-quire specialist knowledge and special tools. Volkswagen Commercial Vehicles recommends using a Volkswagen Commercial Vehicles deal-ership for this purpose.
• Do not insert any objects in the slots of the air outlets. This could cause damage to the air outlets.

Settings for optimal road visibility
• Switch off air recirculation mode 330.
• Set blower® to level 1 or 2.
• Set the temperature selector G) to the required position.
• Open and position all vents on the dash panel.
• Turn the air distribution Fig. 258 0 to the desired position.

.........r'n First read and observe the Introductory L-.lr:.ll Information and safety warnings & on page 322.
The cooling system for the vehicle interior only works when the engine is running and the blower is switched on.
The air conditioning system operates most effec-tively with the windows and the sliding/tilting roof closed. However, if the vehicle has heated up after standing in the sun for some time, the air inside can be cooled more quickly by opening the win-dows and the sliding/tilting roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also the humidity. This improves comfort for the vehicle oc-cupants and prevents the windows from misting when the outside humidity is high.
