Brake (Y page 72) Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are responsible for the distance to the vehicle in
front,f
or vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsa nd maintain asafe distanc efrom
th ev ehicle in front. Drive carefully.
i The driving safety systems describe donly
work as effectivel yaspossible when there
is adequat econtac tbetween th etires and
th er oad surface. Pleas epay special
attentio ntothenote sont ires,
recommende dminimu mtire tread depths,
etc .(Ypage 334).
In wintry drivin gconditions, always use
winter tires (M+S tires) and if necessary,
sno wchains. Only in this way will the
drivin gsafet ysystems described in this
section work as effectively as possible. ABS (Anti-lock Brakin
gSystem)
Important safety notes i
Observe the "Importan tsafet ynotes"
sectio n(Ypage 66). G
WARNING
If ABSisf aulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully.H ave ABS checked
immediately at aqualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 267) and
displaym essages which may be shown in the
instrument cluster (Y page 238).
ABS regulates brake pressure in such away
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking. 66
Driving safety systemsSafety

ABS works fro
maspeed of abou t5mph
(8 km/h )upwar ds,regardless of road-surface
conditions .ABS works on slippery surfaces,
eve nify ou only brake gently.
The yellow 001CABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X To makeaf ull brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
ap ulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as areminder to take extrac are
while driving. BAS (Brake Assist System)
i Observe the "Important safety notes"
section (Y page 66). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergenc ybraking situation is
increased. There is arisk of an accident.
In an emergenc ybraking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergenc ybraking
situations. 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)
General information i
Observe the "Important safety notes"
section (Y page 66).
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
For BAS PLUS to assist you when driving, the
radar sensor system must be:
R activated (Y page 232)
R operational
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.
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 provides braking assistance in
hazardous situations at speeds greater than
4m ph (7 km/h).
At speeds of up to approximately 40 mph
(70 km/h) ,BAS PLUS can also react to
stationary objects. Examples of stationary
object sare stopped or parked vehicles.
Important safety notes G
WARNING
BAS PLUS cannot alwaysc learly identify
object sand complex traffic situations. BAS
PLUS cannot intervene in these cases. There
is ar isk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossin gtraffic
R when cornering Driving safety systems
67Safety
Z

As
aresult, BAS PLUS may not intervene in all
critical situations. There is arisk 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 sensor soranythin gelse
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R an arrow vehicle travelin ginfront, e.g. a
motorbike
R av ehicle travelin ginfrontonad ifferent line
relative to the center of your vehicle
Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensor schecked at aqualified
specialist workshop. This also applies to
collisions at low speeds where ther eisno
visible damage to the fron tofthe vehicle.
Braking assistance To prevent
acollision with the vehicle in front,
BAS PLUS calculates the brake force
necessary if:
R you approach an obstacle, and
R BAS PLUS has detected arisk of collision
When driving at aspeed under 20 mph
(30 km/h):ify ou depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at aspeed greater than
20 mph (30 km/h):ify ou depress the brake
pedal sharply, BAS PLUS automatically raises
the brake pressure to avalue adapted to the
traffic situation.
If BAS PLUS demands particularly high
braking force, preventative passenger protection measures (PRE-SAFE
®
)a re
activated simultaneously.
X Keep the brake pedal depressed until the
emergenc ybraking situation is over.
ABS prevent sthe wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual if:
R you release the brake pedal
R there is no longer arisk of collision
R no obstacle is detected in front of your
