ABS (Anti-lock Braking System)
Important safety guidelines G
Ris
kofa ccident
Do no tdepress 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.
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.
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 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 the prevailing road and weather condi-
tions.
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)
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 is only available in vehicles with
DISTRONIC PLUS.
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. 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.
Otherwise, you may 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 Driving safety systems
57Safety Z

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.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R you release the brake pedal.
R no obstacle is detected in front of your
vehicle.
R there is no longe rany dange rofarear-end
collision.
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
Vehicles without COMAND and a navigation
system and vehicles for Australia: the radar
sensor system and on-board computer must
be switched off in the vicinity of radio tele-
scope facilities (Y page 210).
For BAS PLUS to assist you when driving, the
rada rsensor system must be switched on and
operational. You can chec kthis by activating
DISTRONIC PLUS(Y page 154) or via the
"radars ensor" function in the on-board com-
puter (Y page 210). 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 anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example in
multi-storey car parks
BAS PLUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic,
or when cornering. BAS PLUS may not detect narrow vehicles
such as motorcycles and vehicles driving on
a different line.
Following a collision or accident-related dam-
age to the fron tend of the vehicle, have the
configuratio nand operatio nofthe radar sen-
sors checked at a Mercedes-Benz Service
Centre.
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. 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 .Ifthe
brakes are applied again, the brake lamps
light up continuously.T he 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 . ESP
®
(Electronic Stability Program)
Important safety notes 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 during braking. 58
Driving safety systemsSafety

If 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:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! Do not tow vehicles with 4MATIC with the
front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) 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. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate 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.
Deactivating/activating ESP ®
(except
AMG vehicles) ESP
®
is activated automatically when the
engine is started.
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.E SP®
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 the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides bette rgrip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
will not stabilise the vehicle.
X To deactivate:(Y page 204).
The å ESP®
OFF warning lamp in the
instrument cluster lights up. G
Risk of accident
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running. Driving safety systems

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 fronti s 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 rapidly approaching the vehicle in
front. 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. 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.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ®
Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R brake the vehicle automatically from a
speed of up to approximately 200 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
yourselfa nd others.
With the help of the rada rsensor 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 at first automatically
brake slightly. In the event of an increased
risk of a collision, PRE-SAFE
®
is activated
(Y page 40). If the risk of collision remains
and you do not brake, take evasive action or
accelerate significantly, the vehicle may per-
form automatic emergency braking. 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 can
be impaired 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 the possibility of strong radar reflections,
for example in multi-storey car parks
PRE-SAFE ®
Brake does not react to persons,
animals, oncoming vehicles, crossing traffic
or when cornering.
PRE-SAFE ®
Brake may not detect narrow
vehicles such as motorcycles and vehicles
driving on a different line. G
Risk of accident
Depending on the current speed, PRE-SAFE ®
Brake decelerates your vehicle by up to
4 m/s 2
before performing possible emer-
gency braking. This is equivalent to approx-
imately 40 % of the maximum braking power
of the vehicle. You must additionally apply the
brakes yourself in order to preven tacollision
or minimis ean impact. Automatic emergency
braking is not performed until immediately
prior to an accident in the event that you are
unable to avoid one by, for instance, taking
evasive action.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself. 62
