Belt tensioners, belt force limitersGWARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
i Vehicles with PRE-SAFE ®
: belt tensioners
that are triggered by an electric motor can
be deployed as often as desired and do not
need to be replaced.
The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners
and belt force limiters.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
The belt tensioners can only be activated
when:
R the ignition is switched on
R the restraint systems are operational; see
" 6 SRS warning lamp"( Y page 41)
R the belt tongue is engaged in the buckle on
each of the front seat belts.
The belt tensioners on the outside seats in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
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 and does not indicate that there
is a fire in the vehicle. The powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to
enter the vehicle interior. The 6 SRS warn-
ing lamp lights up.
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 occupant is
reduced.
The belt force limiters on the front seats are
synchronised with the front airbags, which
take on a part of the deceleration force. This
results in the load being distributed over a
greater area.

Child restraint systems
Important safety notes
GWARNING
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
50Children in the vehicleSafety

GWARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy
unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat.
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 recog-
nition on the front-passenger seat: if you turn
the key to position 2 in the ignition lock, the
PASSENGER AIRBAG OFF indicator lamp
lights up briefly. However, the indicator lamp
has no function. It does not indicate that there
is automatic child seat recognition on the
front-passenger seat.
The sensor system for child restraint systems
in the front-passenger seat detects whether
a special Mercedes-Benz child seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case,
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:

ISOFIX child seat securing system for
the rear seats
GWARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose
weight is greater than 22 kg who are secured
using the safety belt integrated in the child
restraint system. The child could, for example,
not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the
child is also secured with the vehicle seat belt.
Also secure the child restraint system with the
Top Tether belt, if available.
54Children in the vehicleSafety

When fitting a child restraint system, be sure
to observe the manufacturer's installation
instructions and the instructions for correct
use of the child restraint system.GWARNING
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 securing a child
restraint system, always observe the manu-
facturer's installation instructions and the
correct use of the child restraint system.
For safety reasons, on the rear seats use only
child restraint systems with an ISOFIX child
seat securing system which have been tested
and approved for Mercedes-Benz vehicles.
An incorrectly fitted child restraint system
could come loose and seriously or even fatally
injure the child or other vehicle occupants.
When fitting the child restraint system, always
make sure that it is engaged correctly in the
ISOFIX securing rings on both sides.
! When fitting the ISOFIX child restraint
system, make sure that the seat belt for the
centre seat does not get trapped. Other-
wise, the seat belt could be damaged.
XInstall the ISOFIX child restraint system.
Comply with the child restrain system man-
ufacturer's instructions when installing the
ISOFIX child restraint system.ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings : for two ISO-
FIX child restraint systems are fitted on the
left and right of the rear seats.
Top Tether
Important safety notes
GWARNING
Always engage the rear seat backrests in an
upright position before installing the Top
Tether belt. Push and pull the rear seat backr-
ests to check whether they are engaged cor-
rectly. The rear seat backrest may fold down
if it is not engaged correctly. The child
restraint system is then no longer supported
correctly or held in position and can no longer
perform its intended function. This can cause
serious or even fatal injuries.
Example: Top Tether belt with one belt strap
Top Tether provides an additional connection
between the ISOFIX child restraint system
secured with ISOFIX and the rear seat. It

facing child restraint.
2 Vehicles with automatic child seat recognition in the front-passenger seat: a child restraint system of the
"Universal" category with a transponder for automatic child seat recognition must be fitted. The PASSENGER
AIRBAG OFF indicator lamp must be lit.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle
is routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height
adjustment so that the belt strap is routed towards the front along the bottom. Move the front-passenger
seat to the highest position and move the backrest to an almost vertical position. When doing so, ensure
that the complete surface of the child restraint system rests against the backrest of the front-passenger seat
and that the child restraint system does not touch the roof. To do so, you may have to adjust the backrest
down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and
most upright position.Children in the vehicle57SafetyZ

Important safety notes
GWARNING
If children adjust the seats, they could
become trapped, especially if they are unat-
tended. There is a risk of injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
GWARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is
a risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under
the lever assembly of the seat adjustment
system.GWARNING

occupant could become trapped by the guide
rail of the seat, for instance. There is a risk of
injury.
Make sure that no one has any part of their
body within the sweep of the seat when
adjusting it.
GWARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event
of an accident, you could slide underneath the
seat belt and sustain abdomen or neck inju-
ries, for example. This poses an increased risk
of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position.
GWARNING
The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted correctly. There is an increased risk
of injury to the head and neck in the event of
an accident or sudden braking, for example.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off.
