Brake servo The brake servo will only function when the en- gine is running and reinforces the pressure ap- plied by the driver on the brake pedal. WARNING Improper maintenance of other vehicle compo- nents or systems or malfunction of relevant components or systems can significantly re- duce the effectiveness of ESC. These compo- nents and systems include (but are not limited to) brakes, tyres, and other systems mentioned in this manual. If the brake servo is not functioning or the vehi- cle is being towed, the brake pedal will have to be depressed more forcefully as the braking dis- tance will be increased due to the lack of assis- tance for the brake system.
WARNING ● Please note that modifications or alterations to the vehicle may impact the functionality of the brake support systems. The brake support systems cannot replace the driver’s attention and operate only within the limits of the respective system. Driving at high speeds on snowy, slippery, or wet roads can re- sult in loss of control over the vehicle and may cause accidents and serious or fatal injuries. ● Modifications to the wheel suspension or the use of unauthorized wheel and tyre combi- nations may affect the operation of the brake support systems. This may reduce the effectiveness of the systems.
● Always adjust your speed and driving style according to visibility, weather, road, and traffic conditions. Never take risks with the improved safety provided by the brake sup- port systems, e.g. ABS, BAS, EDS, ASR, and ESC. ● Always use suitable tyres as the vehicle’s driving stability depends on tyre grip. WARNING Driving without the brake servo or with restric- ted brake servo function can considerably in- crease the braking distance. This can result in accidents and serious or even fatal injury. ● The brake support systems operate only within the limits of the respective system. Even with ESC and other systems, there are inherent risks on slippery and wet roads.
● Never switch the engine or ignition off while the vehicle is in motion. ● Driving too fast on wet roads may cause the wheels to lose traction, resulting in “drift- ing”. If the vehicle loses traction, avoid brak- ing, steering, and attempting to regain con- trol. Troubleshooting Anti-lock brake system failure or fault The indicator lamp lights up yellow. ● Maintaining a safe distance from other vehi- cles and adjusting speed according to road conditions is crucial, as brake support sys- tems cannot prevent accidents caused by following too closely or excessive speed. – Go to a correspondingly qualified workshop. Volkswagen recommends using a Volkswagen dealership.
The vehicle can be braked without ABS. ESC or ASR is performing a control intervention The indicator lamp flashes yellow. ASR has been switched off The indicator lamp lights up yellow. ESC has been switched off due to system restrictions The indicator lamp lights up yellow. There is a fault or a malfunction. ● Although brake support systems can effec- tively assist the driver in controlling the vehi- cle in various situations, it is essential to con- sider the stability of the vehicle and the grip of the tyres on the road. ● Exercise caution when accelerating on slip- pery roads, such as icy or snowy surfaces.
Even with brake support systems, the drive wheels may experience skidding, potentially causing the vehicle to lose steering or be- come difficult to control. Owner's manual 132
