Function 

The brakes for BAS are applied in exactly the same way as with normal brake application, but with BAS the pressure is increased more quickly according to the speed at which the driver presses the brake pedal.

The ESP control unit (N47-5) recognizes that the preconditions exist for activation of BAS from the speed of the brake pedal and the vehicle speed.

BAS is switched on when the following conditions exist:

• The speed is > 10 km/h.
• The stop lamp switch (S9/1) is operated.
• No current fault is detected.
• The system is released after a self-test.
• The pedal speed threshold is exceeded.

BAS is switched off when one of the following conditions is present:

• The brake pedal pressure is reduced by the driver to such an extent that emergency braking is no longer required.
• The stop lamp switch (S9/1) is not operated.
• The speed is < 3 km/h.
• A fault is detected that causes the multifunction display (A1p13) in the instrument cluster (A1) to be activated.
