Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 70)
R BAS ( Brake Assist System) (Y page 64)
R COLLISION PREVENTION ASSIST (adaptive
Brake Assist and distance warning signal)
(Y page 64)
R Adaptive brake lights (Y page 67)
R ESP ®
(Electronic StabilityProgram)
(Y page 67)
R EBD ( Electronic Brake force Distribution)
(Y page 69)
R ADAPTIVE BRAKE (Y page 69)
(Y page 69)
R STEERC ONTROL (Y page 70) 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. Pay particular attention
to th einformatio nregarding tires,
recommended minimum tire tread depths
etc.int he "Wheels and tires" section
(Y page 312).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lockB
raking System)
General information ABS regulate
sbrake pressure in such away
tha tthe wheels do not lock when you brake.
This allowsy ou to continue steering the
vehicle when braking.
The 001C ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes"
section for driving safety systems
(Y page 63). 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 systems Driving safety systems
63Safety
Z

are deactivated. Ther
eisanincreased danger
of skiddin gand accidents.
Drive on carefully. Hav eABS checked
immediately at aqualified specialist
workshop.
When AB Sismalfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 239) and
displaym essages which may be shown in the
instrument cluster (Y page 208).
ABS works from aspeed of about5m ph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery roads,
even if you only brake gently.
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X To make afull 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
functionsasar eminder to take extra care
while driving. BAS (Brake AssistS
ystem)
General information BAS operates in emergency braking
situations. If you depress the brake pedal
quickly,B AS automatically boosts the braking
force, thus shortening the stopping distance.
Important safety notes i
Observe the "Important safety notes"
section (Y page 63). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheelsf rom locking.
Braking X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheelsf rom locking.
The brakes will function as usualo nce you
release the brake pedal. BAS is deactivated. COLLISIONP
REVENTIONASSIST
General notes COLLISION PREVENTION ASSIST consistsof
the Adaptive Brake Assist and the distance
warning function, which are described in the
following.
Distance warning function
Important safety notes
i
Observe the "Important safety notes"
section for driving safety systems
(Y page 63). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncomingv ehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide awarning in all critical situations.
There is arisk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. 64
Driving safety systemsSafety

G
WARNING
Adaptive Brake Assist cannot alwaysc learly
identify objects and comple xtraffic
situations. In these cases, Adaptive Brake
Assist may not intervene. There is arisk of an
accident.
Always pay carefu lattention to the traffic
situation and be read ytobrake. G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R to stationary obstacles
R when cornering
As aresult, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay carefu lattention to the traffic
situation and be read ytobrake.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may alsoc auseBrake Assist to
intervene.
Adaptive Brake Assist aidsy ou in braking
during hazardous situations at speeds above
4m ph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of asenso rsystem, adaptive
Brake Assis tcan detect obstacle sthata re in
th ep athofy our vehicle for an extended
period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected ariskof
collision, Adaptiv eBrake Assist calculate sthe
braking force necessary to avoid arear-end
collision. Should yo uapply the brakes
vigorously ,Adaptiv eBrake Assist will
automaticall yincreas ethe braking force to a
level suitabl efor the traffic conditions.
X Kee pthe brake pedal depressed unti lthe
emergency braking situation is over.
ABS prevents the wheel sfrom locking. The brakes will work normall
yagain if:
R yo ur elease the brake pedal
R there is no longe rany dange rofarear-end
collision.
R no obstacl eisdetected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to vehicl espeeds of around 155 mph
(250 km/h) ,adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to am alfunction in the rada rsensor system,
the brake system remains available with full
brake boosting effect and BAS.
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 rada rsources
R there are strongr adar reflections, for
example in parking garages
R an arrow vehicle traveling in front,e .g. a
motorbike
R av ehicle traveling in front on adifferent line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at aqualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
