ARNING Risk of an accident caused by

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. #

Assist alone. #
Be prepa redto brake or swer veif neces-
sar y. If
Ac tive Brake Assist is deactivated or the func-
tions are restric ted, e.g. due toactivation of
ano ther driving system, theê display message
appears in the driver's displa y.
If th e system is una vailable due todirty or dam-
