Mercedes-Benz S-Class 2012 - Manual (Page 73)

The brakes will work normally again if:
R you release the brake pedal.
R
there is no longer any danger of a rear-end
collision.
R
no obstacle is detected in front of your
vehicle.
BAS PLUS is then deactivated.
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational, see "Radar sensor system" in the
index.
G WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases.
There is a risk of an accident. Always pay
careful attention to the traffic situation and be
ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R
the possibility of strong radar reflections,
for example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
G WARNING
BAS PLUS does not react:
R
to people or animals
R to oncoming vehicles
R to crossing traffic
R in curves
As a result, BAS PLUS cannot intervene in
critical situations. There is a risk of an
accident. Always pay careful attention to the
traffic situation and be ready to brake.
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
If BAS PLUS is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.

Important safety notes
i See the "Important safety notes" section
( Y page 69).
If ESP ® detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP
® assists
the driver when pulling away on wet or
slippery roads. ESP
® can also stabilize the
vehicle during braking.
If ESP
® intervenes, the ÷ ESP ® warning
lamp flashes in the instrument cluster.
G
WARNING

deactivate ESP
® when the ÷ ESP ®
warning lamp in the instrument cluster
flashes. Proceed as follows:
R when driving off, apply as little throttle as
possible.
R while driving, ease up on the accelerator
pedal.
R adapt your speed to suit the prevailing road
and weather conditions.
Failure to observe these guidelines could
cause the vehicle to skid. ESP
® cannot
prevent accidents resulting from excessive
speed.
! The ignition must be switched off if the
vehicle is being towed with the front or rear
