PRE-SAFE ®
takes pre-emptive measure sto
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or for vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
R if the radar senso rsystem detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical driving situations, e.g. when phys-
ical limits are exceed and the vehicle under-
steers or oversteers severely PRE-SAFE
®
takes the following measures
depending on the hazardous situation detec-
ted:
R the fron tseat 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 panorama sliding
sunroo fand the side windows 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 .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 mechanis mis 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.

The NECK-PRO head restraints increase pro-
tection to the driver's and front passenger's
head and neck.T o this end, the NECK-PRO
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision of
a certain severity. This provides better head
support. 50

G
WARNING
Only use head restraint covers which have
been tested and approved by Mercedes-Benz
for yourv ehicle model.
The use of non-approved head restraint cov-
ers may prevent NECK-PRO head restraints
from triggering properly. Consequently, the
NECK-PRO head restraints cannot provide the
intended level of protection.
Consult a Mercedes-Benz Service Centre
regarding availability.
If the NECK-PRO head restraints have been
triggered in an accident, reset the NECK-PRO
head restraints on the driver’s and front-
passenger seat (Y page 51). Otherwise, the
additional protection will not be available in
the event of another rear-end collision. You
can recognise when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted. Resetting triggered NECK-PRO head
restraints
Following a rear-end collision, Mercedes-
Benz recommends that you have NECK-PRO
head restraints checked at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have diffi-
culty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. X
Tilt the top of the NECK-PRO head restraint
cushion forwards in the direction of
arrow :.
X Push the NECK-PRO head restraint cushion
down in the direction of arrow ;as far as
it will go.
X Firmly push the NECK-PRO head restraint
cushion back in the direction of arrow =
until the cushion engages.
X Repeat this procedure for the second
NECK-PRO head restraint. Seat belts
Important safety notes Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with parts of the vehicle interior. G
WARNING
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its intended
protective function. Under certain circum-
stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupants –inparticular,
pregnant women – wear their seat belt cor-
rectly at all times.
R The seat belt must fit snugly on your body
and must no tbe twisted. Therefore, avoid
wearing bulky clothing, e.g. a winter coat. Occupant safety

Page 55 of 373
The shoulder belt section must be routed
across the centre of your shoulder – on no
account across your neck or under your
arm
–and pulled tight against your upper
body .The lap belt must always pass across
your lap as low down as possible, i.e. over
your hip joints –not across your abdomen.
If necessary, push down the belt strap
slightly and then retighten it in the roll-up
direction.
R Do not route the belt strap across sharp
edges or fragile objects, especially if these
are located on or in your clothing, e.g. spec-
tacles, pens, keys, etc. The seat belt strap
could be damaged and tear in an accident,
and you or other vehicle occupants could
be injured.
R Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of other occupants. It
would not be possible to restrain the child
in the event of a sudden change in direc-
tion, braking or an accident .This could
result in severe or even fatal injuries to the
child and other occupants.
R Persons less than 1.50 m tall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 mtall in spe-
cially designed, suitable restraint systems.
R Children less than 1.50 m tall or under 12
years of age canno twear the seat belts
properly. Therefore, they should always be
secured in a suitable child restraint system
on a suitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufacturer's
installation instructions when fitting a child
restraint system.
R Do not secure any objects with a seat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
WARNING
The seat belt does not offer the intended level
of protection unless the backrest is almost vertical. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical.
G
WARNING
Ad irty or damaged seat belt or a seat belt that
has been subjected to a load in an accident
or which has been modified no longer offers
the intended level of protection. Under certain
circumstances, this could cause severe or
even fatal injuries in the even tofanaccident.
For this reason, check regularly that the seat
belts are not damaged or dirty.
Always have damaged sea tbelts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop. Consult a qualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle. 52

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 228).
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 50).
Releasing seat belts X
Press release button ?(Ypage 53) and
guide belt tongue ;back towards belt
sash guide :.
i If you have guided the seat belt back, it is
turned 180 °. This is necessary in order to
guarantee that the seat belt is not twisted
and that it is routed correctly when the belt
is fastened.
! Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.

Belt warning for driver and front
passenger The
7 seatbelt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver or th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the fron tpassenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrumen tcluster, seat
belt" (Y page 273).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. The üsymbol in the display
indicates a fastened seat belt. If a seat belt is
not fastened or if a seat is not occupied, the
ý symbol is displayed.
The rear-compartment seat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again. You can also cancel the rear seat belt status
indicator immediately (Y
page 232).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
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.
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 belt force limiters on the front seats are
synchronised with the front airbags. They
take on a part of the deceleration force,
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 45).
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 seats in the rear
compartment are triggered independently 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- 54
Occupant safetySafety
Page 58 of 373
ates or accelerates rapidly in a lateral direc-
tion
When the belt tensioners are triggered, you
will hear a bang and a small amoun tofpowder
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
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 mtall
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
child could be seriously or even fatally injured.
For this reason, when fitting a child restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. There-
fore, never place objects, e.g. a cushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged covers with genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles.
If a child is travelling in your vehicle, secure
the child using a child restraint system which Children in the vehicle
55Safety Z
Page 59 of 373
is appropriate to the size
,age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should preferably fit the
restraint system to a suitable rear seat. Make
sure that the child is secured in a child
restraint system throughout the trip.
Mercedes-Benz recommends that you only
use the child restraint systems listed at
(Y page 63).
You can obtain further information about the
correct child restraint system from any
Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
You can obtain information about this at
any Mercedes-Benz Service Centre. 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/himself on them.
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.
Also observe the notes on HOLD.R elevant
information can be found in the index. G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects in the vehi-
cle interior unless they are secured. You will find further information under "Loading guide-
lines" in the index.
Child seat lock The seat belts on the rear seats are fitted with
a child seat lock. When enabled, the child-
seat lock function ensures that the belt does

The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with a
transponder for automatic child seat recog-
nition has been fitted. In such cases,
PASSENGER AIRBAG OFF indicator lamp
4: lights up. The front-passenger 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 airbag is disabled
by the automatic child seat recognition, the
following remain enabled on the front-
passenger side:
R the sidebag
R the pelvisbag
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.58
Children in the vehicleSafety
Page 62 of 373
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
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-
tion instructions and the correct use of the
child restraint system.
For reasons of safety, only use child restraint
systems with the ISOFIX child seat securing
system on the rear seats.
We recommend that you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz.
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
securing rings on both sides. 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.
