PRE-SAFE
®
takes the following measures
depending on the hazardous situation detec-
ted:
R the fronts eat belts are pre-tensioned.
R vehicles with the memory function :it
adjusts the front-passenger seat if it is in
an unfavourable position.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroo fand the side win-
dows are closed so tha tonly a small gap
remains.
If the hazardous situatio npasses without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning .The air pressure in the
side bolsters on the multicontour seat is
reduced again. All settings made by PRE-
SAFE ®
can then be reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released. G
WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.

vehicles)
NECK-PRO head restraints/NECK-PRO luxury
head restraints increase protection of the
driver's and front-passenger's head and
neck.Int he event of a rear collision of a cer-
tain severity, the NECK-PRO head restraints/ NECK-PRO luxury head restraints on the driv-
er's and front-passenger seats are moved for-
wards and upwards. This provides better
head support. G
WARNING
Only use head restraint covers which have
been tested and approved by Mercedes-Benz
for your vehicle model.
The use of non-approved head restraint cov-
ers may prevent NECK-PRO head restraints/
NECK-PRO luxury head restraints from trig-
gering properly. The NECK-PRO head
restraints/NECK-PRO luxury head restraints
can therefore not provide the intended pro-
tection.
Consult a Mercedes-Benz Service Centre
regarding availability.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraints have been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver's and front-passenger seats
(Y page 52). Otherwise, the additional pro-
tection will not be available in the event of
another rear-end collision. NECK-PRO head
restraints/NECK-PRO luxury head restraints
that have been triggered are moved forwards
and can no longer be adjusted. Resetting

Seat belt adjustment The seat-belt adjustment function adjusts the
driver's and front-passenger seat belt to the
upper body of the occupants. The belt strap is tightened slightly when:
R
you engage the belt tongue in the belt
buckle and you then turn the key to position
2in the ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the
buckle.
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. On vehicles with a luxury multi-
function steering wheel (12 buttons), you can
switch the seat-belt adjustment on and off
using the on-board computer (Y page 244).
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. More
information about PRE-SAFE ®
can be found
in the "PRE-SAFE ®
(preventative occupant
protection)" section (Y page 51).
Belt height adjustment You can adjust the seat belt height on the
driver's seat and the front-passenger seat.

resulting in the force exerted on the occupant
being distributed over a greater area.
The beltt ensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 47).
R the belt tongue is engaged in the buckle on
each of the three-poin tseat belts in the
front.
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
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. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
! 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. Children in the vehicle

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 1.5 0mtall
or under twelve years of age on the front-
passenger seat .Exception: the vehicle is
equipped with automatic child sea trecog-
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 Children in the vehicle

WARNING
If the front-passenger airbag is not disabled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger airbag deploying. This is espe-
cially a risk if the child is in the immediate
vicinity of the front-passenger airbag when
it deploys.
R never secure a child on the front-passenger
seat in a rearward-facing child restraint sys-
tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R always move the front-passenger seat to
the rearmost position if you secure a child
in a forward-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
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the PASSENGER AIRBAG OFF indicator lamp

is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed on
the dashboard and on both sides of the sun
visor on the front-passenger side.

PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger front airbag is
disabled. G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light 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-passenger seat.
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.
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 windowbag
R the belt tensioner 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.
ISOFIX child seat securing system for
the rear seats ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of 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 using a three-point seat belt. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
