Information about braking assistance systems
Braking assistance systems can assist the driver in critical driving and braking situations. The driver is always responsible for safe driving
If a braking assistance system is regulating, continue braking with the necessary force.
If necessary, steer the vehicle.
⇒
.
WARNING
Braking assistance systems cannot replace the driver's attention and can only operate within the limitations of the system. Fast driving on icy, slippery, or wet
roads, as well as following the vehicle ahead too closely, may impair the vehicle stability and cause you to lose control of the vehicle. If you are careless, there is
a risk of accidents, serious injuries and death.
Always stay attentive and do not rely solely on the system. The driver is always responsible for control of the vehicle.
Always adapt your speed and driving style to the visibility, weather, road and traffic conditions. Do not take any risks.
Always keep the footwell beneath the pedals clear so that the brake pedal is unobstructed and can move freely.
Always use suitable tires, as driving stability depends on the tires' ability to grip the road.
ESC, ABS and ASR only function correctly when all four wheels have the intended tires ⇒
.
If the ABS malfunctions, the ESC, ASR and EDS also fail.
When the ignition is switched on, the condition of the braking functions is automatically checked. The indicator lights will come on briefly and then turn off. If an
indicator light remains on permanently, there is a malfunction. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility immediately.
Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
WARNING
The effectiveness of the ESC may be reduced considerably if other components and systems that affect driving dynamics have not been maintained correctly or
are malfunctioning. This applies in particular to changes made to the suspension and any non-approved wheel and tire combinations. Accidents and serious or
fatal injuries could result.
Ensure that conversion and modifications to the vehicle are only performed by an authorized Volkswagen dealer or authorized Volkswagen Service
Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Always use suitable tires, as driving stability depends on the tires' ability to grip the road.
Electronic Stability Control (ESC)
ESC is regulating the vehicle to reduce the risk of skidding and improve driving stability ⇒
. The indicator light flashes yellow.
Anti-Slip Regulation (ASR)
ASR is regulating the vehicle to reduce the risk of the wheels spinning. The indicator light flashes yellow.
ASR reduces drive power at wheels that are spinning and adapts the drive power to the road conditions. ASR makes it easier to start, accelerate, and drive up hills
⇒
.
Anti-Lock Braking System (ABS)
ABS prevents the wheels from locking during braking so that the vehicle can be steered
⇒
.
Brake Assist System (BAS)
BAS can help to reduce the vehicle braking distance. BAS increases braking power when the driver presses the brake pedal quickly in emergency situations
⇒
Electronic Differential Lock (EDL and XDL)
EDS automatically applies the brakes to a wheel that starts spinning and transfers the drive power to the other driving wheels.
XDS is an extension of the electronic differential lock, and improves traction with braking support to help keep the vehicle in its lane.
Multi Collision Brake
The Automatic Post-Collision Braking System automatically brakes the vehicle if the airbag control module has detected a collision in an accident situation.
Requirements for automatic braking:
The driver does not press the accelerator pedal.
Electronic braking distribution (EBD)
The electronic braking distribution (EBD) regulates the braking force between the front axle and the rear axle, even outside of ABS regulation. Overbraking of the
rear axle is avoided and the vehicle remains stable when braking.
181
Electromechanical brake booster (eBB)
The electromechanical brake booster (eBB) supports the foot pressure only when the ignition is switched on and enhances the pressure applied to the brake pedal
by the driver ⇒
. In case of braking support by a driver assistance system, such as during control by the ACC or during emergency braking, the brake pedal ma
move itself.
After switching off the ignition, braking assistance will be gradually reduced. If the vehicle is still being held by the brake pedal, text messages will appear on the
instrument cluster display. Brake support is limited in this case.
Secure the stationary vehicle against rolling away → page , Parking.
WARNING
Driving without the brake booster or when the brake booster's system function is limited can increase the braking distance significantly. This may lead to
accidents resulting in serious or fatal injuries.
Press the brake pedal harder if the brake booster does not work or the vehicle is being towed.
Always keep the footwell beneath the pedals clear so that the brake pedal is unobstructed and can move freely.
Brake blending
Brake blending takes control between the electric motor braking efficiency during energy recuperation and the driver's mechanical braking.
Switching ASR Sport and ESC Sport on and off
On vehicles with all-wheel drive
(4MOTION), the ESC brake regulation
system can be switched to a sport
mode.
Driving situations
In order to avoid risks, the brake systems should not be switched off under normal conditions
⇒
.
WARNING
When ASR is restricted or ESC Sport is switched on, the risk of the vehicle swerving is significantly higher. The vehicle can be difficult for inexperienced drivers
to handle at high speeds. Accidents and serious or fatal injuries could result.
Only switch on ESC Sport if you are driving on a closed track and are experienced in sporty driving.
Do not take any risks.
Switching on and off
1. Open the vehicle settings of the Infotainment system ⇒ Vehicle settings menu.
2. Open the Vehicle menu.
3. Open the Exterior menu.
4. Open the Brakes menu.
5. Activate the function in the ESC system drop-down list.

ASR Sport
Vehicles with rear-wheel drive: It can be helpful to switch on ASR Sport when the vehicle is driven on loose ground or when “rocking” the vehicle out of place
because it is stuck ⇒
.
This function is available via the ASR off setting in the ESC system drop-down list in the Infotainment system.
ASR Sport switched on. The yellow indicator light turns on.
ESC Sport
The function assists with sporty driving. The ESC intervenes later to stabilize the vehicle, e.g. during fast cornering
