If autonomous braking or situation-dependent
braking assistance has occurred, pop-up
appears in the driver display and then automati-
cally disappears after a short time.
If the autonomous braking function or the situa-
tion-dependent braking assistance is triggered,
additional preventive measures for occupant pro-
®
tection by PRE-SAFE

& WARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and complex traffic situations.
In such cases, Active Brake Assist might:
Give a warning or brake without reason
R
Not give a warning or not brake
R
Active Brake Assist is only an aid. The driver is
responsible for maintaining a sufficiently safe
distance to the vehicle in front, vehicle speed
and for braking in good time.
Always pay careful attention to the traffic
#
situation; do not rely on Active Brake
Assist alone.
1
Be prepared to brake or swerve if neces-
#
sary.
If Active Brake Assist is deactivated or the func-
tions are restricted, e.g. owing to activation of
another driving system, the Active Brake Assist
warning lamp ê appears in the driver display.
If the system is unavailable owing to soiled or
damaged sensors or owing to a fault, or if the
functions are restricted, the Active Brake Assist
warning lamp Ó appears in the driver display.
Also observe the system limits of Active Brake
Assist.

cle in front continues to decrease at higher
speeds, the distance warning lamp L begins
to flash.
