ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Importan tsafety notes" sec-
tion (Y page 64). G
WARNING
If AB Sis faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired.A ddition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABSi s malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 277) and
display messages which may be shown in the
instrument cluster (Y page 250).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.
The yellow !ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func- tions as a reminder to take extra care while
driving. BAS (Brake AssistS
ystem)
i Observe the "Important safety notes" sec-
tion (Y page 64). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist System Plus)
i Observe the "Important safety notes" sec-
tion (Y page 64).
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
BAS PLUS provides braking assistance in haz-
ardous situations at speeds greater than
7k m/h and uses rada rsensor technology to
assess the traffic situation.
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS
calculates the brake force necessary if:
R you approach an obstacle, and
R BAS PLUS has detected arisk of collision Driving safety systems
65Safety Z

If you are driving at a speed over
30 km/h:ify
ou depress the brake sharply,
BAS PLUS automatically raises the brake
pressure to a value adapted to the traffic sit-
uation.
If you are driving at a speed under
30 km/h:ify ou depress the brake, BAS PLUS
is activated. Braking will be carried out at the
last possible moment.
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
) are activated simul-
taneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, 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.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities in the following vehicles:
R vehicles with COMAND Online and naviga-
tion
R vehicles with Audio 20 and Becker ®
MAP
PILOT
Becker ®
MAP PILOT must be connected;
see the separate operating instructions.
The radar sensor system must be switched off
using the on-board computer in the vicinity of
radio telescope facilities in the following vehi-
cles:
R vehicles without COMAND Online and nav-
igation
R vehicles without Audio 20 and Becker ®
MAP PILOT
R vehicles for Australia
For information on switching off the radar
sensor system using the on-board computer,
see (Y page 245). For BAS PLUS to assist you when driving, the
radar sensor system must:
R
be switched on (Y page 245)
R be operational (Y page 263)
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. 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 sit-
uation 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 cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of 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 G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As aresult, 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.
Following damage to the fron tend of the vehi-
cle, have the configuratio nand operatio nof
the rada rsensors checked at a qualified spe- 66
