extending from the front door (A-pillar) to the
rear door (C-pillar). Windowbags
:are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleratio noraccelera-
tion, e.g. in a side impact
R regardless of whethe rthe front-passenger

(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or intervenes powerfully in vehicles with DISTRONIC PLUS, BAS PLUS
or PRE-SAFE ®
Brake
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical situations involving driving
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R vehicles with a multicontour seat or an
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings 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 releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped. 40
Occupant safetySafety

!
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.

PRO luxury head restraints
NECK-PRO head restraints/NECK-PRO luxury
head restraints increase protection of the
driver’s and front-passenger’s head and neck.
In the event of a rear collision of a certain
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
Risk of injury
Head restraint covers prevent NECK-PRO
head restraints/NECK-PRO luxury head
restraints from triggering properly. The NECK-
PRO head restraints/NECK-PRO luxury head
restraints can therefore not provide the inten-
ded protection .Do not use head restraint cov-
ers.
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 41). Otherwise, the additional pro-
tection will not be available in the event of
another rear-end collision. NECK-PRO head

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 ris
kofvehicle occupants coming
into contact with parts of the vehicle interior. G
Risk of injury
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.
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 42
Occupant safetySafety

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
Risk of injury
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
Risk of injury
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. Fastening seat belts

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts .Itmay 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 .Ift he vehicle is stationary and a door is
opened, the 7seat belt warning lamp
goes out and the warning tone ceases.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Indicator and warn-
ing lamps in the instrumentc luster, seat
belt" (Y page 239).
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. 44
Occupant safetySafety

The rear-compartmen
tseat 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 215).
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.
!
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.
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 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
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 35).
R the belt tongue is engaged in the buckle on
each of the three-point seat 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 in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact, on the side
opposite the impact if the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R in certain situations if the vehicle overturns
and the system determines that it can pro-
vide 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. G
Risk of injury
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. Occupant safety

Children in the vehicle
Important safety notes
G
Risk of injury
Do no tleave 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 .Relevant
information can be found in the index. G
Risk of injury
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.
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size, age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should fit the restraint sys-
tem to a suitable rear seat. Make sure that
the child is secured in achild restraint system
throughout the trip.
You can obtain information about the correct
child restraint system from any Mercedes-
Benz Service Centre. i
It is advisable to use Mercedes-Ben zcare
products to clean child restraint systems.
You can obtain informatio nabout this from
any Mercedes-Benz Service Centre. Child restraint systems
Important safety notes Mercedes-Benz recommends that you only
use the child restraint systems listed at
(Y
page 54). G
Risk of injury
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 1.5 0mtall 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 child is
secured in a vehicle with automatic child
sea trecognition on the front-passenger
seat and is secured in achild restraint sys-
tem with 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
Risk of injury
The child restraint system cannot perform its
protective function if it is not correctly fitted 46

visor on the front-passenge rside.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat If your vehicle does not have automatic child
seat recognition 2
on the front-passenger
seat, 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. 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 airbag is disa-
bled. G
Risk of injury
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
2 Vehicles without automatic child seat recognition on the front-passenger seat: if you turn the key to position
2int he ignition lock, the 4PASSENGER AIRBAG OFF indicator lamp lights up briefly but has no function.
It does not indicate that there is automatic child seat recognition on the front-passenger seat. 48
Children in the vehicleSafety

G
Risk of injury
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, whe nswitched 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-
ognitio nsensor 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 automatic child seat recognition fit-
ted, and the front-passenger fron tairbag will
not deploy during an accident .Itis also pos-
sible 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

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
Risk of injury
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
Risk of injury
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
Risk of injury
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. Children in the vehicle
