does not generally constitute a health hazard.
The + 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 +warn-
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 buckles. Otherwise, the
tensioning of the belt by the buckle is restric-
ted or will not function and will not provide
any additional protection. 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.
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 + 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 airbag 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 possible. 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 airbag
as possible. The driver's seat position 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, children
– must not lean their head into the area of
the window in which the sidebag/window-
bag 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 auto-
matic child seat recognition* is only disa-
bled when a child restraint system with
automatic child seat recognition is fitted to
the front-passenger seat. The 4
PASSENGER AIRBAG OFF warning lamp
must be continuously lit.

nition*, or your rearward-facing child
restraint system does not have automatic
child seat recognition, 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 possi-
ble.
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-passenger 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 deploy 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 occu-
pants 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 example,
coat hangers, on the grab handles or coat
hooks.
R do not attach accessories, e.g. cup holders,
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 guaran-
teed if the following parts are not covered 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 diffi-
culties, 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 generally 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 spe-
cialist 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 passeng-
er's head and chest. 38

Driver's front airbag
:deploys in front of the
steering wheel; front-passenger front air-
bag ;deploys in front of and above the glove
compartment. They 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
On vehicles with automatic child seat recog-
nition in the front-passenger seat*, front-
passenger front airbag ;is only deployed if
the 4 PASSENGER AIRBAG OFF warning
lamp in the centre console is not lit
(Y page 43). 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 side-
bag cannot deploy correctly and would fail to
provide the intended protection 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 modi-
fications to the doors or door trim, e.g. retro-
fitting loudspeakers. Damage to the doors
can affect operation of the sidebags.
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. Front sidebags
:or rear-compartment side-
bags* ;deploy next to the outer seat cush-
ions. They are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate

tion, e.g. in a side impact
R independently of the 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

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
to a suitable vehicle seat. The child cannot be
restrained in the event of a sudden 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 sys-
tem, observe the manufacturer's installation
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. Never
place objects, e.g. a cushion, under the child
restraint system.
Only use child restraint systems with their
original covers. Only replace damaged covers
with genuine Mercedes-Benz covers.
For safety reasons, you should only use child
restraint systems which have been approved
for use in Mercedes-Benz vehicles.

Risk of injury
If the front-passenger front airbag is not dis-
abled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger front airbag deploying. This is
especially a risk if the child is in the imme-
diate 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
4 PASSENGER AIRBAG OFF warning
lamp is not lit.
To alert you to this danger, a corresponding
warning sticker is located on the dashboard
and on both sides of the sun visor on the front-
passenger side.
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 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 3
is located on the centre
console. The sensors for the automatic child seat rec-
ognition on the front-passenger seat detects
whether a special Mercedes-Benz child seat
with automatic child seat recognition has
been fitted. In such cases, 4PASSENGER
AIRBAG OFF warning lamp :lights up. The
front-passenger front airbag is disabled. G
Risk of injury
If the 4 PASSENGER AIRBAG OFF warning
lamp does not light up when the child restraint
system is fitted, the front-passenger front air- bag has not been disabled. 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 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 its 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 correctly, never place objects (such as
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 can-
not 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 if the front-passenger front
airbag is disabled by the automatic child-
seat recognition on the front-passenger
seat. G
Risk of injury
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 could lead to a
system malfunction. This may cause the
4 PASSENGER 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 front air-

ment enlargement" section (Y page 154). G
Risk of injury
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could become trapped when
adjusting a seat. G
Risk of accident
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
Risk of injury
Make sure that nobody can become trapped
when you adjust the seat.
