A WARNING
Never switch off the engine while the vehicle Is In motion. This can lead to a loss of vehicle control, accidents and serious injuries.
• The alrbags and belt tensioners will not work If the Ignition Is switched off.
• The brake servo will not work when the engine Is switched off. That is why more pressure on the brake pedal is needed to stop the vehicle when the engine Is switched off.
• The power assisted steering will not work when the engine is not running. More power is needed to steer the vehicle when the en-gine Is switched off.
Electronic immobilizer

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

• 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.

The Automatic Post-Collision Braking System only functions in frontal, side and rear collisions if the airbag control unit registers the corresponding trig-gering threshold during the accident, and the acci-dent occurs at a speed greater than 10 km/h (6 m ph).
The ESC brakes the vehicle automatically, provi-ded that the hydraulic braking system, the ESC and the electrical system are undamaged in the accident and remain functional.
The following actions override automatic braking in the event of an accident:
• When the driver depresses the accelerator. No automatic braking occurs.
• When the brake pressure transmitted through the depressed brake pedal is greater than the brake pressure provided by the system. The vehi-cle is braked manually.
Anti-lock brake system (ABS)
The ABS prevents the wheels from locking when the brakes are applied up until the point where the vehicle is nearly stationary and assists the driver in steering the vehicle and keeping it under control. This means that the vehicle is less likely to spin, even when the brakes are depressed fully:
• Depress and hold the brake pedal with force. Do not take your foot off the brake pedal or reduce the force on the brake pedal.
• Do not pump the brake pedal or reduce the pressure on the brake pedal.
• Steer the vehicle while the brake pedal is fully depressed.
• The ABS will switch off when the brake pedal is released or if the pressure on the brake pedal is reduced.
If the ABS is taking corrective action, there is a pulsing movement in the brake pedal and some noise. However, ABS will not necessarily guaran-tee shorter braking distances in a// conditions. The braking distance could even be longer when brak-ing on gravel or on fresh snow covering an icy or slippery surface.
Brake Assist system (BAS)
The Brake Assist system can help to reduce the braking distance. The Brake Assist system reinfor-ces brake pressure when the driver depresses the brake pedal quickly in an emergency situation. As a result, full braking power is made accessible very quickly, braking power is reinforced and the brak-ing distance reduced. This means that the ABS is activated more quickly and more effectively.
Do not reduce the pressure on the brake pedal. The Brake Assist system will switch off the brake servo automatically when the brake pedal is re-leased or if the pressure on the brake pedal is re-duced.
Traction control system (TCS)
The TCS reduces the engine output if wheels pin occurs and adapts the output to suit road surface conditions. TCS helps the car to start moving, ac-celerate and climb gradients in unfavourable road conditions.
The TCS can be switched on and off manually 276.
Electronic differential lock (EDL)
The EDL is available for normal driving on straight roads. EDL brakes the wheel that has lost traction and distributes the driving force to the other drive wheels. To prevent the disc brake of the braked wheel from overheating, the EDL cuts out automat-ically if subjected to excessive loads. The EDL will switch on again automatically when the brake has cooled down.
A WARNING
Driving fast on icy, slippery or wet roads can lead to a loss of control of the vehicle and could cause serious injury to the driver and passengers.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions. Do not Jet the extra safety afforded by the brake support systems ABS, BAS, EDL, TCS and ESC tempt you into taking any risks when driving.
• The Intelligent technology of the brake support systems cannot overcome the Jaws of physics or system-related vehicle limita-tions. Slippery and wet roads will remain dan-gerous, even when the ESC and other sys-tems are active.
• Driving too fast on wet roads can cause the wheels to Jose contact with the road sur-face and aquaplane. The vehicle cannot be braked, steered or controlled once it has lost contact with the road surface.
• Brake support systems cannot prevent an accident if, for example, you are driving too close to the vehicle in front or are driving too fast for the individual situation. .,.

Q)
• To avoid damage to your vehicle, always ob-serve the indicator lamps and associated warn-ing texts.
• Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt fuel to enter the exhaust system. The catalytic converter or diesel partlculate filter could be damaged as a result!
m The small arrow next to the petrol pump sym-L!J bol 269 shows you which side of the vehicle the tank flap is located on. • The fuel tank is full when the (properly operat-ed) automatic filler nozzle clicks off for the first time
• Do not continue filling the tank after it switches off. The expansion space in the fuel tank will other-wise fill up and the fuel could spill out. This could also happen when the fuel warms up and expands.
Closing the tank cap
• Turn the tank cap clockwise into the fuel filler neck until it perceptibly engages.
• Close the tank flap so that it engages audibly. The tank flap must be flush with the vehicle body-work.
• Close left-hand front door.
A WARNING
Do not continue filling the tank once the filler nozzle stops automatically. The fuel tank could be overfilled. This can cause fuel to splash out and overflow. This can cause fires, explosions and serious Injuries.
Q)
Remove spilt fuel from the vehicle paint as quickly as possible in order to avoid damage to the wheel housing, tyres and vehicle paint.
Spilt fuel can pollute lhe environment.
