If yo u do not react tothewa rning, autonomous
braking can be initiated in critical situations.
In particular lycritical situations, Active Brake
Assist can also initiate autonomous braking
directl y.In this case, thewa rning lamp and warn-
ing tone occur simultaneously with the braking
application.
If yo u apply the brake yourself in a critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent braking assistance
occurs. The brake pressure increases up tomaxi-
mum full-s top braking if necessar y. If autonomous braking or situation-dependent
braking assis

appears in the driver's display and then automati-
cally goes out aTer a short time.
If th e autonomous braking function or the situa-
tion-dependent braking assistance is triggered,
additional pr eventive measures for occupant pro-
te ction (PRE- SAFE®
) may also be initiated. &
W WARNING
ARNING Risk of an accident caused by
limited de tection per form ance of Active
Brake Assist
Ac tive Brake Assist cannot alw ays clear lyiden-
tify objects and complex tra1c situations. In such cases,
Active Brake Assist might:
R Give a warning or brake without reason
R Not give a warning or not brake
Ac tive Brake Assist is only an aid. The driver is
re sponsible for maintaining a su1ciently safe
distance totheve hicle in front, vehicle speed
and for braking in good time. #
Always pay careful attention tothe tra1c
situation; do not relyonActive Brake
Assist alone. #
