R ac hild secured in achild restraint system
on th efront- passenger seat could be seri-
ously and even fatally injured by th efront-
passenge rairbag deploying .This is espe-
cially arisk if the child is in the immediate
vicinity of the front-passenger airbag when
it deploys.
R never secure achild on the front-passenger
seat in arearward-facing child restraint sys-
tem. Only secure arearward-facing child
restraint system on asuitable rear seat.
R always move the front-passenger seat to
the rearmost position if you secure achild
in af orward-facing child restraint system
on the front-passenger seat.
The front-passenger airbag is not disabled:
R on vehicles without automatic child seat
recognition on the front-passenger seat
R in vehicles with automatic child seat rec-
ognition in the front-passenger seat, if no
special child restraint system with trans-
ponders for automatic child seat recogni-
tion in the front-passenger seat has been
fitted

Children in the vehicleSafety

R
only use aforward-facin gchild 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 aqualified 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. acushion, 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 achild
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. If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by
aspecial 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 detectsw
hether 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

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 328).
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. ABS (Anti-lockB
raking System)
Important safety notes i
Observe the "Important safety notes" sec-
tio n(Ypage 62). G
WARNING
If ABS is faulty, the wheels could lock when
braking .The steerability and braking charac-
teristics may be severely impaired. Addition-
ally,f urther 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 aqualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 261) and
displaym essages which may be shown in the
instrumentc luster (Ypage 232). ABS regulates brake pressure in such
away
that the wheels do not lock when you brake.
This allowsy ou to continue steering the vehi-
cle when braking.
ABS works from aspeed of about 8km/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
instrumentc lusterlight supw hen the ignition
is switched on. It goes out when the engine is
running.

If ABS intervenes: continue to depressthe
brak epedal with force until the braking sit-
uation is over.
X To make afull brake application:

WARNING
If BA Sism alfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk 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 PLUS (Brak
eAssis tSystem Plus)
i Observ ethe "Important safety notes "sec-
tio n(Ypage 62).
BAS PLU Sisonly 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 detec tobstacles 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 stationar yobstacles,
for example, stopped or parked vehicles.
To prevent afront-end collision, BAS PLUS
calculates the brake force necessary if:
R yo ua pproach an obstacle, and
R BAS PLUS ha sdetected arisk of collision
If you ar edriving at aspeed over
30 km/h:ify ou depress the brake sharply,
BAS PLUS automatically raises the brake
pressure to avalue adapted to the traffic sit-
uation.
If you are driving at aspeed under
30 km/h:ify ou depress the brake, BAS PLUS
is activated. Brakin gwill be carried out at the
last possible moment.
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
)a re activated simul-
taneously.
X Keep the brake pedal depressed until the
emergenc ybraking situation is over.
ABS prevent sthe wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual,i f:
R you release the brake pedal.
R there is no longer any danger of arear-end
collision.
R no obstacle is detected in front of your
vehicle. The radar sensor system is switched off auto-
matically in the vicinit
yofradio telescope
facilities in the following vehicles:
R vehicles with COMAND Online and naviga-
tion
R vehicles with Audio 20 and Becker ®
MAP

For BAS PLUS to assist you when driving, the
radar sensor system must:
R be switched on (Y page 225)
R be operational (Y page 245)
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS. G
WARNING
BAS PLUS cannot alwaysc learly identify
object sand complex traffic situations. BAS
PLUS cannot intervene in these cases. There
is ar isk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-

If you brake sharply from aspeed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly.
In this way,t raffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspeed of more
than 70 km/h to astandstill, 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 button (Y page 114). ESP

tion (Y page 62). 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 with 4MATIC: switch off the igni-
tion when the parking brake is being tested
using adynamometer.
Application of the brakes by ESP ®

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 amalfunction.
Observe the information on warning lamps
(Y page 263) and display messages which
may be shown in the instrument cluster
(Y page 232).
If ESP ®
detect sthat 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 ®
