When the belt tensioners are triggered you
will hear a bang, which will not cause any
harm to your hearing, and a small amount of

ing lamp lights up. 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.
When the the airbags are triggered you will
hear a bang, which will not cause any harm to your hearing, and a small amount of powder
may also be released. The
1warning lamp
lights up.
The SRS/AIRBAG symbol indicates the loca-
tion 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.
R 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. On the front-
passenger seat, the front-passenger
front airbag is only deactivated if a child
restraint system with automatic child
seat recognition is fitted to the front-
passenger seat*. The 5PASSENGER
AIRBAG OFF warning lamp must be con-
stantly lit.
If either the rearward-facing child
restraint system or the front-passenger
seat* of your vehicle do not have auto-
matic child seat recognition, children
must be secured in a child restraint sys-
tem on a suitable seat in the rear. If you Safety

Occupant safety
44 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 front seats
R Rear door trims 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. G
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. Safety

Sidebags
1and 2are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R independently of seat belt use
R independently of the front airbags
R independently of the belt tensioners
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
lateral direction and determines that side-
bag deployment can offer additional pro-
tection to that provided by the seat belt
Windowbags
The purpose of the windowbags is to enhance
the level of protection for the head (but not
chest or arms) of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The windowbags are integrated into the side
of the roof frame and run from the front door
(A-pillar) to the rear door (C-pillar). Saloon shown as an example

The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with auto-
matic child seat recognition has been fitted.
In such cases, 5PASSENGER AIRBAG
OFF indicator lamp 1lights up. The front-
passenger airbag is deactivated. G
Risk of injury
If the 5 PASSENGER AIRBAG OFF warn-
ing lamp does not light up when the child
restraint system is fitted, the front-
passenger front airbag has not been disa-
bled. If the front-passenger front airbag is
deployed, 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 sys-
tem 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 its rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist work-
shop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions correctly, never place objects (such
as a cushion) under the child restraint sys-
tem. The entire base of the child restraint
system must always rest on the seat cush-
ion. An incorrectly fitted child restraint sys-
tem cannot perform its intended protective
function in the event of an accident, and
could lead to injuries.
i The windowbag, the sidebag and the belt
tensioner on the front-passenger side are still active even when the front-passenger
front airbag is disabled. G
Risk of injury
Do not place items of electronic equipment
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 recognition sensor system. This can
lead to a system malfunction. This may
cause the 5PASSENGER AIRBAG OFF
warning lamp to light up without there
being a child seat with automatic child seat
recognition fitted. This means that the
front-passenger airbag is not deployed dur-
ing an accident. It is also possible that the
5 PASSENGER AIRBAG OFF warning
lamp will not light up briefly if you turn the
key in the ignition lock to position 2.Safety

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 The shoulder belt section of the seat belt
must be routed across the middle of the
child's shoulder – never across the
child's neck – and be pulled tight against
the child's chest. The lap section of the
seat belt must be routed across the
child's pelvis – not across the abdomen
– and be pulled tight against the child's
body; retighten the belt strap if neces-
sary.
R Never secure more than one child at a
time in the child restraint system.
R The belt must be routed through the
hook.
R The belt strap must not be trapped or
twisted, nor rub against any sharp edges. Also observe the assembly instructions for
the padded table and the additional warn-
ings and information about risk of injury.
