restraint system
Do not use a rearward-facing child restraint
system on a seat that is protected by an air-
bag installed in fron tofit.
Automatic chil dseat recognition on the
front-passenger seat G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
to rlamp does no tlight up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, the child could be
seriously or even fatally injured.
Proceed as follows:
R do not use a rearward-facing child restraint
system on the front-passenge rseat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or R
only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. a cushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being a child
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIRBAG OFF indicator lamp does not light up
briefly when you turn the key in the ignition
lock to position 2.56
Children in the vehicleSafety

If yourv
ehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Vehicles without automatic child seat recog-
nition on the front-passenger seat: when you
turn the key to position 2inthe ignition lock,
the 4 PASSENGER AIRBAG OFF indicator
lamp lights up briefly, but does not have any
function. It does not indicate that there is
automatic child seat recognition on the front-
passenger seat. The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Ben zchild seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case, 4
PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger front airbag is
disabled. i
If the front-passenger front airbag is dis-
abled by the automatic child seat recogni-
tion, the following remain enabled on the
front-passenger side:
R the sidebag
R the pelvisbag
R Coupé:t he windowbag
R Cabriolet: the headbag

ISOFIX child seat securing system for
the rear seats G
WARNING
Ac hild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
a child restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system with the vehicle seat belt as well. In
addition, when fitting a child restraint system,
be sure to observe the manufacturer's instal-
lation instructions and the instructions for
correct use of the child restraint system. G
WARNING
Please note that if child restraint systems, or
their retaining systems, are damaged or sub-
jected to a load in an accident, they may not
be able to provide their protective function.
This could result in serious or even fatal inju-
ries to the secured child in the event of an
accident, heavy braking or a sudden change
in direction.
For this reason, have child restraint systems
and their anchorages which have been dam-
aged or subjected to a load in an accident
checked immediately at a qualified specialist
workshop. Children in the vehicle

Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 65)
R BAS (Brake AssistSystem) (Y page 65)
R BAS PLUS(Brake AssistSystem PLUS)
(Y page 65)
R Adaptive brake lamps (Y page 67)

R PRE-SAFE ®
Brake (Y page 69) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of accident nor over-
ride the laws of physics. Driving safety sys-
tems are merely aids designed to assist driv-
ing. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time. Always adapt your driv-
ing style to suit the prevailing road and
weather conditions and maintain a safe dis-
tance from the vehicle in front. Drive care-
fully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tyres and
the road surface. Please pay special atten-
tion to the notes on tyres, recommended
minimum tyre tread depths, etc.
(Y page 340).
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. 64

ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Importan tsafety notes" sec-
tion (Y page 64). G
WARNING
If AB Sis faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired.A ddition-
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.
When ABSi s malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 277) and
display messages which may be shown in the
instrument cluster (Y page 250).
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.
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 indica-
tion of hazardous road conditions and func- tions as a reminder to take extra care while
driving. BAS (Brake AssistS
ystem)
i Observe the "Important safety notes" sec-
tion (Y page 64). 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.
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. BAS PLUS (Brake Assist System Plus)
i Observe the "Important safety notes" sec-
tion (Y page 64).
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
BAS PLUS provides braking assistance in haz-
ardous situations at speeds greater than
7k m/h and uses rada rsensor technology to
assess 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.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS
calculates the brake force necessary if:

cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. Adaptive brake lamps
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 button (Y page 127). ESP
®
(Electronic Stability Program)
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 64). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
Vehicles without 4MATIC: observe the notes
on ESP ®
if the vehicle is being towed with the
rear axle raised (Y page 334).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction. Observe the information on warning lamps
(Y
page 278) and display messages which
may be shown in the instrument cluster
(Y page 250).
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. 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 slippery roads. ESP ®
can also stabilise the vehicle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depress the accel-
erator pedal as far as is necessary.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
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. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
.
Deactivating/activating ESP ® G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident. Driving safety systems

in the situations descri-
bed in the following.
X To deactivate:(Y page 240).
The å ESP®

engine is started.
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically .ESP ®
remains in its pre-
viously selected status. Example :ifESP®
was
deactivated before the engine was switched
off, ESP ®
remains deactivated when the
engine is switched on again.
If ESP ®
is deactivated and one or more wheels
star tto spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
will not stabilise the vehicle.
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
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R engine torque is not limited and the drive
wheels are able to spin. The spinning of the
wheels results in a cutting action for better
traction.
ESP ®
trailer stabilisation G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high centre of gravity can
tip over before ESP
®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/
trailer combination by depressing the brake
firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 64). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increa-
ses the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 277) as well as dis-
play messages (Y page 252).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. 68
