Air bags
Introduction
The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt. The
air bag provides additional protection in appli-
cable accident situations.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another (
Ypage 52).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out arisk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RAdjust 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.
RMove the driver's and front-passenger seats
as far back as possible.T he driver's seat posi-
tion must allow the vehicle to be driven safely.
ROnly hold the steering wheel on the outside.
This allowst he air bag to be fully deployed.
RAlways 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.
RAlways keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
RFor this reason, always secure persons less
than5ft(1.50 m) tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If ac hild is traveling in your vehicle,a lso
observe the following notes:
RAlways secure children under twelve years of age and less than 5ft(1.50 m)tallins uitable
child restraint systems.

Objects in the vehicle interior may prevent
an air bag from functioning correctly.Before
starting your journey and to avoid risks resulting from the speed of the air bag as it deploys, make
sure that:
Rthere are no people, animals or objects
between the vehicle occupantsa nd an air bag
Rthere are no objectsbetween the seat, door
and B-pillar
Rthere are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks
Rno accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an air bag, e.g. to doors, side windows,
rear side trim or side walls
Rno heavy, sharp-edged or fragile object sare in
the pocket sofyour clothing. Store such
object sinas uitable place
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modification sorwork not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensor sbeing impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protec tvehicle occupantsast hey 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 pan-
eling carried out at aqualified specialist work-
shop.
Front air bags
!Do not place heavy object sonthe front-
passenger seat. This could cause the system
to identif ythe 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.
Driver's air bag
:deploys in frontoft he steer-
ing wheel. Front-passenger fronta ir bag;

When deployed, the fronta ir bags offer addi-
tional head and thorax protection for the occu-
pants in the fronts eats.

Safety

The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg pro-
tection for the occupantsinthe front seats.
Side impact air bags
GWARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protec tvehicle occupantsast hey are
designed to do. In addition, the operation 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.
Fronts ide impact air bags :and rear side
impact air bags ;deploy next to the outer bol-
ster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. It also offers addi-
tional pelvis protection for occupantsint he
front seats. However, it does not protec tthe:
RHead
RNeck
RArms
If the restraint system control unit detect saside
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:
Rthe OCS system detect sthat the front-
passenger seat is occupied or
Rthe 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 accident situation
occurs. In this case, deployment is independent
of whether the front-passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags
:are integrated into
the side of the roof frame and deployed in the
area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protec tthe chest or arms.
If the restraint system control unit detect saside
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, awindow curtain air bag may be
deployed in other accident situations
(
Ypage 52).
Occupant Classification System

sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if only parts which are relatively easilyd eformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as aresult.
If the restraint system control unit detects aside
impact or if the vehicle rolls over, the applicable
componentsoft he restraint system are activa-
ted independently of each other depending on
the apparent type of accident.

iNot all air bags are deployed in an accident.
The different air bag systems work independ- ently of each other. How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
RFrontal collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe engine is switched off and the fuel supply
is cut off
Rvehicles with mbrace: automatic emergency

Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
ac hild restraint system on arear seat. Children
are generally better protected there.
If ac hild younger than twelve years old and
under 5ft(1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in achild restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
Rbe sure to observe the instructions and safety notes on the "Occupant classification system
(OCS)" (
