Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
R BAS (Brake AssistSystem)
R COLLISION PREVENTION ASSIST (BAS
PLUS and distance warning signal)
R Adaptive brake lamps
R ESP ®
(Electronic StabilityProgram) R
EBD ( electronic brake force distribution)
R STEER CONTROL Important safety notes
G
WARNING
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt your driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road.
If you fail to adapt your driving style, the driv-
ing 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 responsi-
ble for the distance to the vehicle in front, for
vehicle speed and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions as
well as the traffic conditions, and maintain a
safe distance from the vehicle in front. Drive
carefully.
i Please note that the driving safety sys-
tems described only work as effectively as
possible when there is adequate contact
between the tyres and the road surface.
Pay particular attention to the information
regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and
tyres" section (Y page 292).
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. 62
Driving safety systemsSafety

ABS (Anti-lock Braking System)
Important safety notes G
WARNING
If AB Sis faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adapty our driving style to
suit the prevailing road and weather condi-
tions.
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.
i Observe the "Important safety notes" sec-
tion (Y page 62).
Brakes G
WARNING
Do not depress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect .You
might otherwise not be able to stop the vehi-
cle in time and could cause an accident.
Depress the brake pedal firmly and smoothly.
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 Assist)
G
WARNING
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
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.
i Observe the "Important safety notes" sec-
tion (Y page 62). COLLISION PREVENTION ASSIST
General notes COLLISION PREVENTION ASSIST consists of
the BAS PLUS system and the distance warn-
ing signal, which are described in the follow-
ing.
Distance warning
G
WARNING
The distance warning signal cannot always
clearly identify objects and complex traffic
situations. Driving safety systems

the rada
rsensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the fron tofthe vehicle.
i Observe the "Important safety notes" sec-
tion (Y page 62).
BAS PLUS (Brake Assist System Plus) 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. G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R to stationary obstacles
R when cornering
As a result, BAS PLUS may not intervene in
critical situations. There is a risk of an acci-
dent. Always pay careful attention to the traf-
fic situation and be ready to brake.
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor system to evaluate
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.
Should you approach an obstacle and BAS
PLUS has detected a risk of collision, BAS
PLUS calculates the braking force necessary
to avoid a rear-end collision. Should you apply
the brakes forcefully, BAS PLUS will automat-
ically increase the braking force to a level
suitable for the traffic conditions. 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 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.
Vehicles with PRE-SAFE ®
:if BAS PLUS
requires particularly high brake pressure, pre-
ventative passenger protection measures
(PRE-SAFE ®
) are deployed simultaneously.
Up to vehicle speeds of around 250 km/h,
BAS PLUS is capable of reacting to moving
objects that have already been recognised as
such at least once over the period of obser-
vation. BAS PLUS does not react to stationary
obstacles.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor 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 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
motorbike
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.
