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 escapes
does not generally constitute a health hazard.
The 1 warning lamp lights up.
i If the belt buckle tensioners have been
triggered on the front seats, the buckle will
be pulled down and will be almost flush with
the upper edge of the seat. The 1warn-
ing lamp comes on. G
Risk of injury
The belt buckle tensioners on the front
seats only function if the belt buckles can
be pulled down without obstruction. They must not be restricted in any way. For this
reason, do not hold the belt buckles and do
not place any objects under the belt buck-
les. Otherwise, the tensioning of the belt by
the buckle is restricted or will not function
and will not provide any additional protec-
tion.
G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protec-
tion in the event of another accident.
Therefore, have belt tensioners which have
been triggered replaced at a qualified spe-
cialist workshop.
Comply with safety regulations when dis-
posing of belt tensioners. Any Mercedes-
Benz Service Centre can provide details of
these regulations.
Airbags Airbag deployment slows down and restricts
the movement of the vehicle occupant.
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 escapes
does not generally constitute a health hazard.
The 1 warning lamp lights up. The SRS/AIRBAG identification indicates the
location of the airbags. G
Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for seat
belts.
Observe the following notes to reduce the
risk of serious or even fatal injury if an air-
bag is deployed:
R all vehicle occupants — in particular preg-
nant women — must wear their seat belt
correctly at all times and lean back
against the backrest, which should be
positioned as close to the vertical as pos-
sible. The head restraint must support
the back of the head at about eye level.
R always secure children less than 1.50 m
tall or under 12 years of age in suitable
child restraint systems.
R all vehicle occupants must select a seat
position that is as far away from the air-
bag as possible. The driver's seat posi-
tion must allow the vehicle to be driven
safely. The driver's chest should be as far
away from the middle of the driver's front
airbag cover as possible. Safety

move the front-passenger seat as far
back as possible, especially if a child is
secured in a child restraint system on the
seat.
R vehicle occupants – in particular, chil-
dren – must not lean their head into the
area of the window in which the sidebag/
windowbag is deployed.
R Rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger front air-
bag has been disabled. The front-
passenger front airbag of a vehicle fitted
with automatic child seat recognition* is
only disabled when a child restraint sys-
tem with automatic child seat recogni-
tion is fitted to the front-passenger seat.
The 5 PASSENGER AIRBAG OFF
warning lamp must be constantly lit.
If the front-passenger seat of your vehicle
does not have automatic child seat rec-
ognition*, or your rearward-facing child
restraint system does not have such a
feature, children must be secured in a
child restraint system on a suitable seat
in the rear. 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 make sure there are no heavy or sharp-
edged objects in pockets of clothing.
R do not lean forwards, e.g. over the cover
of the driver's front airbag, particularly
when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel by the rim.
This allows the airbag to inflate fully. You
could be injured if the airbag is deployed
and you are holding the inside of the
steering wheel.
R do not lean on the doors from inside the
vehicle.
R make sure that there are no people, ani-
mals or objects between the vehicle
occupants and the area of deployment of
the airbag.
R do not place any objects between the
seat backrest and the door.
R do not hang any hard objects, for exam-
ple coat hangers, on the grab handles or
coat hooks.
R do not attach accessories, e.g. cup hold-
ers, to the doors. It is not possible to rule out a risk of injuries
caused by an airbag due to the high speed
at which the airbag is required to deploy.
G
Risk of injury
The airbag's functionality can only be guar-
anteed if the following parts are not cov-
ered and no badges or stickers are
attached to them:
R padded steering wheel boss
R front-passenger front airbag cover
R outer side of seats G
Risk of injury
When an airbag deploys, a small amount of
powder is released. The powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions.
In order to prevent potential breathing dif-
ficulties 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
interior. The powder does not constitute a
health hazard and does not indicate that
there is a fire in the vehicle. Safety

Risk of injury
The airbag parts are hot after the airbag has
been deployed. Do not touch them, other-
wise you may burn yourself.
Have the airbags checked at a qualified
specialist workshop. Otherwise, occupants
are not protected by the airbags in the
event of another accident.
Front airbags
The front airbags are designed to increase
protection for the driver's and front-
passenger head and chest.
The driver's front airbag and front-passenger
front airbag are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deployment can offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbags in the vehi-
cle
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
longitudinal direction 1
Driver's front airbag
2 Front-passenger front airbag
Driver's front airbag 1deploys in front of the
steering wheel; front-passenger front airbag
2 deploys in front of and above the glove
compartment.
On vehicles with automatic child seat recog-
nition in the front-passenger seat*, front-
passenger front airbag 2is only deployed if
the 5 PASSENGER AIRBAG OFF warning
lamp in the centre console is not lit
(Y page 50). This means that there is not a
child restraint system with automatic child
seat recognition* fitted to the front-
passenger seat or that a child restraint sys-
tem with automatic child seat recognition*
has been fitted to the front-passenger seat
incorrectly. Sidebags G
Risk of injury
If you wish to use seat covers, Mercedes-
Benz recommends that, for safety reasons,
you only use seat covers that have been
approved for Mercedes-Benz vehicles.
The seat covers must have a special tear
seam for sidebags. Otherwise, a head/
thorax airbag cannot deploy correctly and
would fail to provide the intended protec-
tion in the event of an accident. Appropriate
seat covers can be obtained from a
Mercedes-Benz Service Centre. G
Risk of injury
Sensors to control the airbags are located
in the doors. Therefore, do not make any
modifications to the doors or door trims,
e.g. retrofitting loudspeakers. Damage to
the doors can affect operation of the side-
bags.
The purpose of sidebag deployment is to
enhance the level of protection for the thorax
(but not the head, neck or arms) of the vehicle
occupants on the side of the vehicle on which
the impact occurs. Safety

Occupant safety
47
If you are driving faster than approximately
35 km/h, PRE-SAFE
®
takes the following
measures in the aforementioned situations:
R It tensions the front seat belts.
R Vehicle with memory functions*: it adjusts
the front-passenger seat if this is in an
unfavourable position.
R If the vehicle skids, it closes the sliding/
tilting sunroof* and side windows so that
only a small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
releases
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
again.
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases. G
Risk of injury
Make sure when adjusting the seat that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when adjusting
the seats. You could otherwise damage the
seats and the objects. NECK-PRO head restraint
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck. To this end, the
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision
when viewed in the direction of travel. This
provides better head support. G
Risk of injury
Head restraint covers prevent the NECK-
PRO head restraints from triggering cor-
rectly. Consequently, the NECK-PRO head
restraints cannot provide the intended level
of protection. Do not use head restraint
covers.
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 304). Head restraints that have
been triggered are tilted forwards. Children in the vehicle
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size and age of the child
and recommended for Mercedes-Benz vehi-
cles. You should preferably fit the restraint
system to a suitable rear seat. Ensure that the
child is strapped in 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-Benz care
products to clean child restraint systems.
Information about this can be obtained
from any Mercedes-Benz Service Centre. G
Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. Children could injure
themselves on parts of the vehicle. They
could also be seriously or even fatally
injured by prolonged exposure to extreme
heat or cold.
Do not expose the child restraint system to
direct sunlight. The metallic parts of the
child restraint system could heat up and the
child could be burned by them. Safety

Occupant safety
48 If a child opens a door, the child or other
persons could be injured as a result. The
child could get out and be injured in the
process or be injured by a passing vehicle. G
Risk of injury
An unsecured or incorrectly positioned load
increases the risk of injury to the child in
the event of:
R an accident
R a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects inside
the vehicle unless they are secured. You
will find further information under "Loading
guidelines" in the index.
Child restraint systems Mercedes-Benz recommends that you only
use the child restraint systems listed on.
(Y page 53) 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 1.50 m tall and under
twelve years of age must always be
secured in special child restraint systems
on a suitable vehicle seat. This is neces-
sary because the seat belts are not
designed for children of this size.
R do not secure children under twelve
years of age on the front-passenger seat.
Exception: the child is secured in a vehi-
cle with automatic child seat recognition
on the front-passenger seat* and is
secured in a child restraint system with
automatic child seat recognition.
R if you secure a forward-facing child
restraint system to the front-passenger
seat that is not equipped with automatic
child seat recognition, 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 occurring 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 inte-
rior and be seriously or even fatally
injured.
G
Risk of injury
The child restraint system cannot perform
its protective function if is not correctly fit-
ted to a suitable vehicle seat. The child
cannot be restrained in the event of a sud-
den change of direction, heavy braking or
an accident. This may lead to serious or
even fatal injuries. For this reason, when
fitting a child restraint system, observe the
manufacturer's installation instructions
and the correct use of the child restraint
system.
Child restraint systems should preferably
be fitted to the rear seats. Children are gen-
erally better protected there.
The entire base of the child restraint system
must always rest on the seat cushion.
Never place objects, e.g. a cushion, under
the child restraint system.
Only use child restraint systems with their
original covers. Only replace damaged cov-
ers with genuine Mercedes-Benz covers. Safety
