Brake support
If the risk of collision still increases after the
collision warning then the brake support is acti-
vated. The brake support prepares the brake
system for rapid braking and the brakes are
applied gently, which may be noticed as a
slight jerk.
If the brake pedal is depressed sufficiently
quickly then full brake function is implemented,
even with light pedal force.
Auto Brake
If the driver has not yet started an evasive
manoeuvre in this situation and the risk of a
collision is imminent then the Auto Brake func-
tion comes into effect, without the driver need-
ing to touch the brake pedal. Braking then
takes place with limited brake force in order to
reduce collision speed. The driver has to brake
in order to achieve full brake force.
Operation
Settings are made from the centre console dis-
play via a menu system. For information on
how the menu system is used, see page 130.
NOTE
The Brake Support and Auto Brake func-
tions are always enabled - they cannot be
