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

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

Risk of injury
If the front-passenger front airbag is not
disabled:
R a child secured in a child restraint system
on the front-passenger seat could be
seriously and even fatally injured by the
front-passenger front airbag deploying.
This is especially a risk if the child is in
the immediate vicinity of the front-
passenger front airbag when it deploys.
R a child must never be secured on the
front-passenger seat in a rearward-facing
child restraint system. 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 front airbag is not dis-
abled:
R on vehicles without automatic child seat
recognition in the front-passenger
seat*.
R on vehicles without automatic child seat
recognition on the front-passenger
seat*, if no special child restraint system
with automatic child seat recognition has
been fitted to the front-passenger seat.
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat*, if
the 5 PASSENGER AIRBAG OFF warn-
ing lamp is not lit.
To draw attention to this danger, there is an
appropriate warning sticker on the dash-
board as well as on both sides of the sun

Automatic child seat recognition on the
front-passenger seat*
If your vehicle does not have automatic child
seat recognition 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. It is visible when
you open the front-passenger door.
The warning lamp 13
is located on the centre
console. 1
5 PASSENGER AIRBAG OFF warning
lamp 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.
13 Vehicles without automatic child seat recognition in the front-passenger seat: the warning lamp lights up briefly when you turn the key to position 2 in the ignition

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 could
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 does not deploy
during an accident. It is also possible that
