Belt tensioners do not correct incorrect seat
positions or incorrectly fastened sea
tbelts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupan tis
reduced.
The front beltf orce limiters are synchronised
with the front airbags, which take on a part of
the deceleration force. Thus, the force exer-
ted on the occupant is distributed over a
greater area.
The belt tensioners can only be activated if:
R the key is in position 1or 2in the ignition
lock.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R for each three-point seat belt in front and
for the outer rear seats, the seat belt
tongue is engaged in the belt buckle.
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side.
The belt tensioners are triggered depending
on the type and severity of an accident:
R if, in the event of a head-on or rear-end col-
lision, the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R in certain situations where the vehicle over-
turns and the system determines that it can
provide additional protection
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up. Children in the vehicle
Child restraint systems
Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R children less than 1.50 m tall and under
twelve years of age must always be secured
in special child restraint systems on a suit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R do not secure children less than 1.50 m tall
and under twelve years of age on the front-
passenger seat. Exception: if the vehicle is
equipped with automatic child seat recog-
nition on the front-passenger seat and the
child is secured in a child restraint system
with transponders for automatic child seat
recognition
R if you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction .The
child could be seriously or even fatally injured.
For this reason, when fitting a child restraint
system, observe the manufacturer's installa- 48
Children in the vehicleSafety

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 withou tthere 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. If the front-passenger seat of your vehicle
does not have automatic child seat recogni-
tion, 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
recognition on the front-passenger seat: if
you turn the key to position 2inthe ignition
lock, the 4PASSENGER AIRBAG OFF indi-
cator lamp lights up briefly but has no func-
tion. It does not indicate that there is auto-
matic child seat recognition on the front-
passenger seat. The automatic child seat recognition sensor
system on the front-passenger seat detects
whether a special Mercedes-Ben
zchild seat
with automatic child seat recognition has
been fitted there. In such cases, 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 windowbag
R the belt tensioner
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. Children in the vehicle

Child-proof locks
Important safety notes G
WARNING
Activate the child-proof locks for the rear
doors and the override switch for the rear
windows when childre nare travelling in the
vehicle. Otherwise, the children could open
doors or side windows while the vehicle is in
motion and injure themselves or others. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himsel fonthem. If a child opens a door, the child or other per-
sons could be injured as a result. They could
get out and injure themselves or be injured by
a passing vehicle.
Child-proof locks for the rear doors You secure each door individually with the
child-proof locks on the rear doors.
Adoor
secured with a child-proof lock cannot be
opened from inside the vehicle. When the
vehicle is unlocked, the door can be opened
from the outside. 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 60)
R BAS ( Brake Assist System) (Y page 61)
R Adaptive brake lamps (Y page 61)
R ESP ®
(Electronic StabilityProgram)
(Y page 62)
R EBD ( electronic brake force distribution)
(Y page 64)
R ADAPTIVE BRAKE (Y page 64)
R Trailer stabilisation Important safety notes
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 322).
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)
