Vehicle features and options Brake assistant
This chapter describes model-specific equip-
ment, systems, and functions that are currently
available, or may become available in the fu-
ture, even if they are not present in the vehicle.
The brake assistant automatically applies
maximum braking assistance when the brake
pedal is depressed quickly. This reduces the
braking distance to a minimum for full braking.
Additional information:
To make full use of braking assistance, do not
reduce the pressure on the brake pedal during
full braking.
Vehicle equipment, refer to page 8.
Antilock Braking System
Dynamic Stability Control
Principle
Principle
The Antilock Braking System prevents locking
of the wheels during the braking process.
Dynamic Stability Control helps keep the vehi-
cle on a steady course in critical driving situa-
tions. The drive power is reduced depending
on the situation, and wheels can be braked
individually.
You remain able to steer your vehicle even dur-
ing full braking, which increases active driving
safety.
General information
The Antilock Braking System is ready after
each time drive-ready state is turned on.

The system detects the following unstable
driving conditions, for instance:
▷
▷
Skidding, which can lead to oversteering.
Malfunction

can lead to understeering.
The warning light on the instrument
cluster illuminates.
A Check Control message is displayed.
