Air bags
Introduction The installation point of an airbag can be rec-
ognized by the AIRBAG marking.
An airbag complements the correctly fastened
seat belt. It is no substitute for the seat belt.
When deployed, an airbag can increase the
protection provided for the respective vehicle
occupant.
Not all airbags are deployed in an accident.
The various airbags work independently of
each other (Y page
58).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an airbag due to the high speed at
which the airbag must be deployed.
Important safety notes G
WARNING
If the front passenger air bag has been acti-
vated, a child on the front passenger seat
may be hit by the front passenger air bag in
the event of an accident. There is a risk of
injury or fatal injury.
NEVER use a rearward-facing child restraint
system on a seat protected by an ACTIVE
FRONT AIRBAG; DEATH or SERIOUS INJURY
to the CHILD can occur.
When installing a child restraint system on the
front-passenger seat observe the vehicle-spe-
cific notes

(Y page 64). You must observe
the notes on rearward and forward-facing child
restraint systems on the front-passenger seat. G
WARNING
If you deviate from the correct seat position,
the air bag cannot perform its intended pro-
tective function and deployment may even
cause further injuries. This poses an
increased risk of injury or even fatal injury.
To avoid any risks, each vehicle occupant
must always make sure of the following:
R Fasten the seat belt correctly. In the case
of pregnant women in particular, make sure that the lap belt is never routed
across the stomach or abdomen.
R Adopt the correct seat position and keep
as far away as possible from the air bags.
R Observe the following notes.
Always make sure that there are no objects
between the air bag and vehicle occupant.
All vehicle occupants must observe the follow-
ing notes to avoid risks posed by the air bag
when it deploys.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat
position must allow the vehicle to be driven
safely.
R Only hold the steering wheel on the outside.
This allows the air bag to be fully deployed.
R Always lean against the backrest while driv-
ing. Do not lean forward or lean against the
door or side window. You may otherwise be
in the deployment area of the air bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the air
bag.
R For this reason, always secure persons less
than 5 ft

(1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R Always secure children under twelve years
of age and less than 5 ft (1.50 m) tall in suit-
able child restraint systems.
R Child restraint systems should preferably be
installed on the rear seats.
R Secure a child to the front-passenger seat
only when the front-passenger front air bag
is deactivated, and then only in a rearward-
facing child restraint system. The front-
passenger front air bag is deactivated when
the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 47).
R Always observe the instructions and safety
notes on the "Occupant Classification Sys- Occupant safety
51
Safety Z

tem (OCS)" (Y page
54) and on "Children
in the vehicle" ( Y page 60) in addition to
the child restraint system manufacturer's
installation and operating instructions.
Objects in the vehicle interior may restrict
the air bag from functioning correctly. To
avoid risks resulting from the speed of the air
bag as it deploys, vehicle occupants must
ensure the following points.
Before commencing your journey, ensure that:
R there are no people, animals or objects
between the vehicle occupants and an air
bag
R there are no objects between the seat, door
and B-pillar
R there are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks
R no accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors or side
windows
R no heavy, sharp-edged or fragile objects are
in the pockets of your clothing. Store such
objects in a suitable place G
WARNING
If you modify the cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
Vehicles with window curtain air bags for
all seat rows: G
WARNING
Sensors to control the air bags are located
in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to
the function of the sensors being impaired.
The air bags might therefore not function
properly anymore. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. There is an
increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or door paneling carried out at a qualified spe-
cialist workshop.
Front air bags !
Do not place heavy objects on the front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied.
In the event of an accident, the restraint
systems on the front-passenger side may be
triggered and have to be replaced. The driver's air bag
: deploys in front of the
steering wheel. The co-driver's air bag ;
deploys in front of and above the glove box
and center console.
When deployed, the front air bags offer addi-
tional head and thorax protection on the front
seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the co-driver's
air bag

(Y page 47).
The co-driver's air bag will deploy only if:
R the Occupant Classification System (OCS)
has detected that the co-driver's seat is
occupied ( Y page 54). The PASSENGER
AIR BAG OFF indicator lamp is not lit
( Y page 54)
R the restraint system control unit predicts a
high accident severity
Side impact air bags G
WARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they
are designed to do. In addition, the opera- 52
Occupant safety
Safety

tion of the occupant classification system
(OCS) could be adversely affected. This
poses an increased risk of injury or even
fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Side impact air bags
: deploy next to the
outer bolster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax and pelvis protection. How-
ever, it does not protect the:
R head
R neck
R arms
If the restraint system control unit detects a
side impact, the side impact air bag is
deployed on the side on which the impact
occurs.
The side impact air bag on the front passenger
side deploys under the following conditions:
R the OCS system detects that the front
passenger seat is occupied or
R the seat belt buckle tongue is engaged in
the belt buckle of the front passenger seat
If the belt tongue is engaged in the belt
buckle, the side impact air bag on the front
passenger side deploys if an appropriate acci-
dent situation occurs. In this case, deployment
is independent of whether the front passenger
seat is occupied or not. Window curtain air bags
Example: window curtain air bag above the front
door
Example: window curtain air bag for all seat rows
Window curtain air bags : or ; are integra-
ted into the side of the roof frame. Window
curtain air bags for all seat rows ; deploy in
the area extending from the front door (A-pil-
lar) to the rear side window (D-pillar).
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or
arms.
If the restraint system control unit detects a
side impact, the window curtain air bag is
deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
(Y page
58). Occupant safety

Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
Conditions To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classifi-
cation, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place objects
under or behind the child restraint system, e.g.
a cushion. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The back-
rest of the forward-facing child restraint sys-
tem must lie as flat as possible against the
backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation and operat-
ing instructions. Occupant Classification System (OCS)

When the front-passenger seat is occupied,
always pay attention to the PASSENGER AIR
BAG OFF indicator lamp. Be aware of the sta-
tus of the front-passenger front air bag both
before and during the journey.
If the PASSENGER AIR BAG OFF indicator
lamp:
R lights up, the front-passenger front air bag
is deactivated. It will then not be deployed
in the event of an accident.
R is not it , the front-passenger front air bag is
