ABS works from a speed of about 6 km/h,
regardless of road-surface conditions. ABS
intervenes in the case of slippery road sur-
faces, even when you only brake gently.
X
To brake while ABS intervenes: continue to
depress the brake pedal with force until
the braking situation is over.
X
To make a full brake application: depress
the brake pedal with full force.
G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety sys-
tems are deactivated. There is an increased
danger of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
Using Active Brake Assist
Useful information
With the help of the radar sensor system,
Active Brake Assist can calculate the dis-
tance of your vehicle to the vehicle travelling
in front.
If for several seconds, the distance to the
vehicle ahead is insufficient for the speed
you are driving at, Active Brake Assist alerts
the driver visually.
If a risk of collision is detected, Active Brake
Assist alerts the driver both visually and
acoustically. In addition, Active Brake Assist
prepares the vehicle for a possible emer-
gency braking manoeuvre.
In particularly critical situations Active
Brake Assist may brake autonomously. In
this case, Active Brake Assist continues to
alert the driver both visually and acousti-
cally.
Please note
G
WARNING
Active Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In these cases, Active Brake Assist may:
warn or brake for no reason
R
not issue a warning
R
not brake
R
There is a risk of an accident.
Always pay careful attention to the traffic
situation and do not rely on Active Brake
Assist alone. Be prepared to brake or
manoeuvre if necessary.
G
WARNING
Active Brake Assist does not react:
to persons, bicycles, motorcycles or ani-
R
mals
to approaching vehicles
R
to cross traffic
R
on bends
R
As a result, Active Brake Assist cannot
intervene in all critical situations. There is
a risk of an accident.
Always pay careful attention to the traffic
situation and be prepared to brake.
G
WARNING
Severe jolting, for example in the case of a
collision, may cause the radar sensors to
be misaligned. The function of Active Brake
Assist is then impaired.
There is a risk of an accident.
Deactivate Active Brake Assist. Have Active
Brake Assist checked at a qualified spe-
cialist workshop.
The following requirements must also be ful-
filled:
the selector lever is in position h.
R
the parking brake is released.
R
the driving speed is within the suitable
R
speed range.
Detection can be restricted under the follow-
ing conditions:
the vehicle is new or service work has been
R
carried out on the system. In this case,
Driving safely
