Mercedes-Benz 2013 C Class Coupe - Manual (Page 74)

With the aid of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
BAS PLUS can help you to minimise the risk
of a collision with a vehicle or reduce the
effects of such a collision. If BAS PLUS
detects a danger of collision, you are assisted
when braking.
Important safety notes
G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
R
intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
G
WARNING
BAS PLUS does not react:
R
to people or animals
R to oncoming vehicles
R
to crossing traffic
R when cornering
As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, recog-
nition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R
dirt on the sensors or the sensors are
obscured
R
interference by other radar sources
R
strong radar reflections, for example, in
multi-storey car parks
R
a narrow vehicle travelling in front, e.g. a
motorcycle
R
a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper-
ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
When driving at a speed under 30 km/h:
if you depress the brake pedal, BAS PLUS is
activated. Braking assistance from BAS PLUS
is carried out at the last possible moment.
When driving at a speed above 30 km/h:
if you depress the brake pedal sharply, BAS
PLUS automatically increases the brake pres-
sure to a degree suited to the traffic situation.
BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within
a speed range between 7 km/h and
250 km/h.
At speeds of up to approximately 70 km/h,
BAS PLUS can also detect stationary objects.
Examples of stationary objects are stopped
or parked vehicles.
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE
® ) are activa-
ted simultaneously.
