Driving safety systems
Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 68)
R BAS (Brake AssistSystem) (Y page 69)
R Active Brake Assist (Y page 69)
R Adaptive brake lights (Y page 71)
R ESP ®
(E lectronic StabilityProgram)
(Y page 72)
R EBD (electronic brake forcedistribution)
(Y page 75)
R ADAPTIVE BRAKE (Y page 75)
R STEER CONTROL (Y page 75)Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override
the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance
from the vehicle in front. Drive carefully.
The driving safety systems described work as
effectively as possible only when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 335).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when braking. The
! ABS warning lamp on the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
brake only gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 68). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
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.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 267) and display mes-
sages that may be shown on the instrument
cluster (Y page 235).
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 indication
of hazardous road conditions; this serves as a
reminder to take extra care while driving.
Off-road ABS An ABS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (Y
page 192).
At speeds below 30 km/h, the front wheels lock
cyclically during braking. The digging-in effect
achieved in the process reduces the stopping 68

distance during off-road driving. This limits
steering capability. BAS (Brake Assist System)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes i
Read the "Important safety notes" section
(Y page 68). 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.
Braking X
Keep the brake pedal depressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Active Brake Assist
General information i
Observe the "Important safety notes" sec-
tion (Y page 68).
Active Brake Assist consists of a distance warn-
ing function with an autonomous braking func-
tion and situation-dependent braking assis-
tance.
Active Brake Assist can help you to minimise the danger of collision with the vehicle in front or
reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk
of collision, you will be warned visually and
acoustically. If you do not react to the visual and audible collision warning, autonomous braking can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Adap-
tive Brake Assist supports you with situation-
dependent braking assistance.
Important safety notes Detection of hazardous situations can be par-
ticularly impaired by:
R
dirt on the sensors or obscured sensors
R snow or heavy rain
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
R new vehicles or after servicing is carried out
on the Active Brake Assist system
Observe the important safety notes in the
"Running-in notes" section (Y page 143).
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at low
speeds where no visible damage to the front of
the vehicle is apparent.
Switching on/off Active Brake Assist is active after every ignition
cycle.
You can activate or deactivate Active Brake
Assist (Y page 227) in the on-board computer.
When the system is deactivated, the distance
warning function and the autonomous braking
function are also deactivated.
If Active Brake Assist is deactivated, the æ
symbol appears in the assistance graphic dis-
play.
If you have activated DSR, Active Brake Assist is deactivated. Further information on DSR
(Y page 190).
Distance warning function General information
The distance warning function can help you to
minimise the danger of collision with the vehicle
in front or reduce the effects of such a collision. If the distance warning function detects a risk of Driving safety systems

Situation-dependent braking assis-
tance
General information
i Observe the "Important safety notes" sec-
tion (Y page 68).
With the help of the radar sensor system, Adap- tive Brake Assist can detect obstacles that are in
the path of your vehicle for an extended period
of time.
If Adaptive Brake Assist detects a risk of colli-
sion with the vehicle in front, it calculates the
brake pressure necessary to avoid a collision. If
you apply the brakes forcefully, the situation-
dependent braking assistance automatically
increases the brake pressure to a degree appro- priate to the traffic situation.
Situation-dependent braking assistance pro-
vides braking assistance in hazardous situations at speeds above 7 km/h. It uses the radar sen-
sor system to assess the traffic situation.
Situation-dependent braking assistance is capa-
ble of reacting to moving objects which have
already been recognised as such at least once
over the period of observation, up to a speed of around 250 km/h.
Situation-dependent braking assistance can
also detect stationary objects, up to a speed of
around 70 km/h.
If situation-dependent braking assistance
demands particularly high brake pressure, pre-
ventative passenger protection measures (PRE-
SAFE ®
) are triggered simultaneously
(Y page 55).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R a danger of collision with the vehicle in front
no longer exists
R no obstacle is detected in front of your vehicle
Situation-dependent braking assistance is then
deactivated.
Important safety notes i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 68). G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. The risk of
an accident remains.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
R intervene unnecessarily
R not intervene
The risk of an accident remains.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due to a malfunction in the radar sensor system, the
brake system is still available with full brake
boosting effect and BAS. Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency braking situation by: R flashing brake lamps
R the hazard warning lamps are activated
If you brake sharply from a speed of more than
50 km/h or if braking is assisted by BAS or BAS
PLUS, the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an even more noticeable manner.
If you brake sharply from a speed of more than
70 km/h to a standstill, the hazard warning
lamps are switched on automatically. If the Driving safety systems
