In poor road and weather conditions, the trailer

de tects this. #
Always adapt your driving style tosuit the

imately 65 km/h.

e Assist Ac
tive Brake Assist consists of thefo llowing func-

R Distance warning function
R Autonomous braking function
R Situation-dependent brake forc e boosting Ac
tive Brake Assist can help youto minimise the
ri sk of a collision with vehicles, cyclists or pedes-
trians, or reduce the e.ects of such a collision.
If Ac tive Brake Assist has de tected a risk of colli-
sion, a warning tone sounds and theL warning
lamp lights up in the instrument cluster.
If yo u do not react tothewa rning, autonomous
braking can be initiated in critical situations. In
especially critical situations, Active Brake Assist
can initiate autonomous braking directl y.In this
case, thewa rning lamp and warning tone are acti-
va ted simultaneously with the braking application.
If yo u apply the brake yourself in a situation de tec-
te d as critical byActive Brake Assist, or app lythe
brake during autonomous braking, situation-
dependent brake forc e boosting occurs. The brake
pressure increases up tomaximum full-s top brak-
ing if necessar y.
If autonomous braking or a situation-dependent
braking boosting e.ect has occur red, theL
wa rning lamp 0ashes brie0y and then goes out.

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. #
Be prepared tobrake or swer veif neces-
sar y. Obser
vethe system limitations of Active Brake
Assist. Due tothe nature of the system, complex
but non-critical driving conditions may also cause
Ac tive Brake Assist tointer vene during braking. Driving and parking
