Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R BAS PLUS* ( Brake Assist System Plus*)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electronic brake-power distribution)
R ADAPTIVE BRAKE
R Distance warning function* (vehicles with
Distronic*)
R PRE-SAFE ®
Brake* (vehicles with Distronic
Plus*)
i 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. G
Risk of accident
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 suit prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road. 48

ABS (Anti-lock Braking System)
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. G
Risk of accident
Do not depress the brake pedal several times
in quick succession (pumping). Depress the
brake firmly and evenly. Pumping the brake
pedal reduces the braking effect.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
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. G
Risk of accident
If ABS is 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, BAS PLUS* and ESP ®
are also
deactivated. There is an increased risk of your
vehicle skidding in certain situations.
You should always adapt your driving style to
suit prevailing road and weather conditions. BAS (Brake Assist)
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. X
Keep the brake pedal firmly depressed 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. G
Risk of accident
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. BAS PLUS* (Brake Assist Plus)
BAS PLUS provides braking assistance in haz-
ardous situations and uses radar sensor tech-
nology to assess the traffic situation. G
Risk of accident
BAS PLUS is only an aid to assist you when
driving. You are responsible for maintaining a
safe distance from other vehicles, for the vehi-
cle's speed and for braking in good time.
Always pay attention to the traffic conditions.
You may otherwise recognise dangers too
late, cause an accident and injure yourself
and others.
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected obsta-
cle quickly, BAS PLUS calculates the braking
force necessary to avoid a rear-end collision.
Should you additionally apply the brakes, BAS
PLUS will automatically increase the braking
force to a level suitable for the traffic condi-
tions.
If BAS PLUS demands particularly high brak-
ing force, PRE-SAFE ®
is activated simultane-
ously.
X Keep the brake pedal depressed until the
emergency braking situation is over.

The brakes will work normally again when:
R you release the brake pedal
R no obstacle is detected in front of your
vehicle
R there is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h, BAS
PLUS can also detect stationary obstacles,
for example, stopped or parked vehicles.
Vehicles with COMAND and a navigation sys-
tem*: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 411).
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You can check this by activating
Distronic Plus* (Y page 235) or via the
"Radar sensor" menu in the on-board com-
puter (Y page 226). G
Risk of accident
Only clearly identified obstacles will initiate
braking assistance by BAS PLUS. In particular,
the detection of obstacles can be restricted if
there is:
R dirt on the sensors or the sensors are cov-
ered
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example in
multi-storey garages
BAS PLUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic.
BAS PLUS may not detect narrow vehicles
such as motorcycles and vehicles driving on
a different line.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked at a Mercedes-Benz Service Centre.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor system, the braking system remains available with full brake
boosting effect and BAS. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
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 warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 196). ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle when braking.
When ESP ®
intervenes, the ÷warning
lamp flashes in the instrument cluster. G
Risk of accident
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows: 50

R
Under no circumstances should you deac-
tivate ESP ®
.
R When pulling away, only depress the accel-
erator pedal as far as is necessary.
R Adapt your driving style to the prevailing
road and weather conditions.
The vehicle may otherwise begin to skid.
If you drive too fast, ESP ®
cannot reduce the
risk of an accident. ESP ®
cannot override the
laws of physics.
! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
! Vehicles with 4MATIC* may not be towed
with the front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example, if the road surface is slippery on one
side.
Traction control remains active when you
deactivate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Activating/deactivating ESP ®ESP
®
is activated automatically when the
engine is running. It may be best to deactivate ESP
®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
i If ESP ®
is deactivated and one or more
wheels start to spin, the ÷warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilise the vehi-
cle.
X To deactivate: (Ypage 224).
The å warning lamp in the instrument
cluster lights up. G
Risk of accident
If the å warning lamp in the instrument
cluster lights up when the engine is running,
ESP ®
is deactivated or is unavailable due to a
malfunction. The risk that your vehicle may
start to skid then increases in certain situa-
tions.
Always adapt your driving style to the prevail-
ing road and weather conditions. Driving safety systems

The å warning lamp in the instrument
cluster goes out. EBV (electronic brake force distribu-
tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability when braking. G
Risk of accident
If EBV is malfunctioning, the brake system is
still available with full brake boosting effect.
However, the rear wheels can still lock, e.g.
under full braking. This could cause you to
lose control of your vehicle and cause an acci-
dent. You should therefore adapt your driving
style to the different handling characteristics. ADAPTIVE BRAKE
ADAPTIVE BRAKE offers exceptional braking
comfort and a higher level of braking safety.
In addition to the braking function, ADAPTIVE
BRAKE also has the HOLD convenience func-
tion (Y page 245) and hill start assist
(Y page 204). For further information, see
Driving tips (Y page 304). Distance warning function* (vehicles
with Distronic*)
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which you are travelling. The
· distance warning lamp in the instru-
ment cluster will light up.
R you are approaching the vehicle in front too
rapidly. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster. In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
crash, you must apply the brakes yourself. G
Risk of accident
Pay particular attention to the traffic condi-
tions if the distance warning lamp ·in the
instrument cluster lights up or an intermittent
warning tone sounds.
If necessary, brake or manoeuvre to avoid an
obstacle.
X To activate/deactivate: activate or deac-
tivate the distance warning function in the
on-board computer (Y page 223).
After activating, the Äsymbol is dis-
played in the left-hand section of the multi-
function display.
For more information on the distance warning
function, see the Distronic section*
(Y page 229). PRE-SAFE
®
Brake* (vehicles with Dis-
tronic Plus*)
PRE-SAFE ®
Brake can help you to minimise
the risk of a frontal collision with a vehicle in
front or reduce the effects of such a collision.
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which you are travelling. The
· distance warning lamp in the instru-
ment cluster will light up.
R you are approaching the vehicle in front too
rapidly. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning. 52

G
Risk of accident
Pay particular attention to the traffic condi-
tions if the distance warning lamp ·in the
instrument cluster lights up or an intermittent
warning tone sounds. If necessary, brake or
manoeuvre to avoid an obstacle.
In addition, at speeds of around 30 km/h or
more, PRE-SAFE ®
Brake can:
R brake the vehicle gently and automatically
within a speed range of up to around
180 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) G
Risk of accident
PRE-SAFE ®
Brake is only an aid to assist you
when driving. You are responsible for main-
taining a safe distance from other vehicles,
the vehicle's speed and for braking in good
time. Always pay attention to the traffic con-
ditions. Otherwise, you may recognise dan-
gers too late, cause an accident and injure
yourself and others.
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time. If you approach an obstacle
and PRE-SAFE ®
Brake detects a risk of a col-
lision, the system will initially alert you both
visually and acoustically. If you do not brake
or steer, the vehicle will automatically brake
slightly. In the event of an increased risk of a
collision, PRE-SAFE ®
is activated
(Y page 42). G
Risk of accident
Only clearly detected obstacles will trigger a
warning and initiate braking assistance by
PRE-SAFE ®
Brake. In particular, the detection of obstacles may
be restricted if there is:
R
dirt on the sensors or the sensors are cov-
ered
R snow or heavy rain
R interference from other radar sources
R strong radar reflections, for example in
multi-storey car parks
PRE-SAFE ®
Brake does not react to persons,
animals, oncoming vehicles and crossing traf-
fic.
PRE-SAFE ®
Brake may not detect narrow
vehicles such as motorcycles or vehicles driv-
ing on a different line. G
Risk of accident
Depending on the vehicle's speed, PRE-
SAFE ®
Brake will brake your vehicle up to
maximum of 4 m/s 2
. This is equivalent to
approximately 40 % of the maximum braking
power of the vehicle. You must also apply the
brakes yourself to avoid a collision.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
crash, you must apply the brakes yourself.
At speeds up to approximately 70 km/h,
PRE-SAFE ®
Brake can also detect stationary
obstacles, for example stopped or parked
vehicles. G
Risk of accident
If, in a critical driving situation, you do not
receive a visual and acoustic warning:
R PRE-SAFE ®
Brake did not detect the risk of
a collision
R PRE-SAFE ®
Brake is deactivated
R PRE-SAFE ®
Brake has failed
You must then brake to avoid a collision. Driving safety systems

PRE-SAFE ®
Brake does not always clearly
identify complex traffic situations properly.
You can terminate the intervention of PRE-
SAFE ®
Brake in a non-critical driving situation
at any time if:
R an acoustic and visual warning occurs
R the vehicle brakes gently
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal.
The braking intervention of PRE-SAFE ®
Brake
is ended automatically if:
R you manoeuvre to avoid the obstacle.
R you drive slower than approximately
15 km/h.
R there is no longer an obstacle detected in
front of your vehicle.
R there is no longer any danger of a collision.
i While Distronic Plus is activated, PRE-
SAFE ®
Brake remains passive.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked. Choose a qualified specialist work-
shop for this which has the necessary spe-
cialist knowledge and tools for the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. Anti-theft systems
