Occupant safety
Safety

Never modify an air bag cover or affix objects
to it.
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.
Alway sh ave work on the doors or door pan-
eling carried out at aq ualifie ds pecialist work-
shop.
Front air bags
! Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied .Int he
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.
Driver's air bag C deploys in front of the steer-
ing wheel .F ront-passenger front air bag D
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps inform you about
the status of the front-passenger air bag
( Y
page 38). The front-passenger front air bag wil lo nly
deplo yi f: R
the system, based on the OCS weight sensor
readings, detects that the front-passenger

Kne eb ags
Driver's knee bag C deploys under the steering
column and front-passenger knee bag D under
the glove box. The driver's and front-passenger
knee bags are triggered together with the front
air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lowe rl eg pro-
tection.
Side impact air bags
G WARNING
Unsuitabl es eat 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 operatio no f
the occupant classification system (OCS)
could be adversel ya ffected. This poses an
increased risk of injury or even fatal injury.
You shoul do nly use seat covers that have
been approve df or the respective seat by

Safety Z

If the front passenger does not observe these
conditions, OCS may produce af alse classifica-
tion, e.g. because the front passenger: R
transfers their weight by supporting them-
selves on av ehicle armrestR
sits in such aw ay that their weight is raised
from the seat cushion
If you install ac hild 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. ac ushion. The entire base
of the child restraint system must always rest on
the seat cushio noft he front-passenger seat.
The backrest of the forward-facing child
restraint system 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 al oad by the head
restraint. Adjust the angle of the seat backrest
and the head restraint positio na ccordingly.
Only then can OCS be guaranteed to function
correctly. Alway so bserve the child restraint sys-
tem manufacturer's installation and operating
instructions.

G WARNING
If you secure ac hild in ar earward-facing child
restraint system on the front-passenge rs eat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenge rf ront air bag
may deploy in an accident. The child coul db e
struck by the air bag .T his pose sani ncreased
risk of injury or even fatal injury.
Make sure that the front-passenge rf ront air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install ar ear-
ward-facing child restraint system on the front-
passenger seat. You can find more information
on OCS under "Problems with the Occupant
Classification System" ( Y
pag e4 8).
G WARNING
If you secure ac hild in af orward-facing child
restraint system on the front-passenge rs eat
and you position the front-passenge rs eat too
close to the dashboard, in the event of an
accident, the child could: R
come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example R
be struck by the air bag if the PASSENGER
AIR BAG ON is lit up
This poses an increased risk of injury or even
fatal injury.
Move the front-passenge rs eat as far back as
possible .A lways make sure that the shoulder
bel ts trap is correctly routed from the vehicle
bel tl oop to the shoulde rb el tg uide on the
child restraint system. The shoulde rb el ts trap
must be routed forwards and downwards
from the bel tl oop .A lways observe the child
restraint system manufacturer's installation
instructions.
If OCS determines that: R
the front-passenge rs eat is unoccupied ,t he
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and remains lit. This indicates that the front-
passenger front air bag is deactivated. R
the front-passenge rs eat is occupied by a
child of up to twelve months old, in as tandard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenge rf ront air bag is
deactivated.
But even in the case of at welve-month-old
child ,inas tandard child restraint system, the
PASSENGER AIR BAG ON can light up perma-
nently after the system self-test. This indi-
cates that the front-passenge rf ront air bag is
activated. The result of the classification is
dependent on, among other factors, the child
restraint system and the child's stature. Make
sure that the conditions for ac orrect classi-
ficatio na re met. If the PASSENGER AIR BAG
OFF indicator lamp is still lit, do not install a
child restraint system on the front-passenger
seat. R
the front-passenge rs eat is occupied by ap er-
son of smaller stature (e.g. at eenage ro r
smal la dult), either the PASSENGER AIR BAG
ON or PASSENGER AIR BAG OFF indicator
lamp lights up and remains lit after the system
self-test depending on the result of the clas-
sification. -
If the PASSENGER AIR BAG ON indicator
lamp lights up, move the front-passenger
seat as far back as possible. -
If the PASSENGER AIR BAG OFF indicator
lamp is lit, ap erso nofs maller stature
should not use the front-passenge rs eat.R
the front-passenge rs eat is occupied by an
adult or ap erso nofa dult stature, the
PASSENGER AIR BAG ON indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front air bag is activated.
If children are traveling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
( Y
pag e5 1).
When OCS is malfunctioning, the red u
restraint system warning lamp in the instrument
cluster and the PASSENGER AIR BAG OFF indi-
cator lamp light up simultaneously .T he front-
passenger front air bag is deactivated in this
case and does not deploy during an accident.
Have the system checked by qualified techni-
cians as soon as possible .C onsult an authorized
Mercedes-Benz Center. The front-passenger46

seat should only be repaired at an authorized
Mercedes-Benz Center.
If the front-passenger seat, the seat cover or the
seat cushion is damaged ,h ave the necessary
repair work carried out at an authorized
Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories that
have been approved by Mercedes-Benz.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag will
also deploy .T he Occupant Classification Sys-
tem (OCS) categorizes the occupant in the front-
passenger seat. Depending on that result, the
front-passenger front air bag is either enabled or
deactivated.
System self-test
G DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front air bag might be triggered
unintentionally or might not be triggered at all
in the event of an accident with high deceler-
ation. This poses an increased risk of injury or
even fatal injury.
In this case the front-passenger seat may not
be used. Do not install ac hild restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at aq ualified spe-
cialist workshop.
G WARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenger front air bag is disabled. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when ap erson is seated in the front-
passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash- board. This poses an increased risk of injury or
even fatal injury.
When the front-passenger seat is occupied,
always ensure that: R
the classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat R
the person is seated properly with ac or-
rectly fastened seatbelt R
the front-passenger seat has been moved
as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front-
passenger seat may not be used. Do not
install ac hild restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediately at aq ualified specialist work-
shop.
G WARNING
Objects between the seat surface and the
child restraint system could affect OCS oper-
ation. This could result in the front-passenger
air bag not functionin gasi ntended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must, as far as
possible ,ber esting on the backrest of the
front-passenger seat. Always comply with the
child restraint system manufacturer's instal-
lation instructions.
After the system self-test, the PASSENGER AIR
BAG OFF or PASSENGER AIR BAG ON indicator
lamp displays the status of the front-passenger

Air bags and pyrotechnic Emergenc yT ensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines must
be observed during disposal. In California, see

Method of operation Durin gt he first stage of ac ollision, the restraint
system control unit evaluates important physi-
cal data relatin gtov ehicle deceleration or accel-
eration ,s uch as:R

situations: R
Fron ta ir bags as well as driver' sa nd front-

air bag can only deploy in an acciden tift he
PASSENGER AIR BA GONi ndicator lamp is lit.
Observe the information on the PASSENGER AIR
BA Gi ndicator lamps ( Y
page 38).
Your vehicle has two-stage fron ta ir bags. During
the first deployment stage, the fron ta ir bag is
filled with propellant gas to reduce the risk of
injuries. The fron ta ir bag is fully deployed with
the maximum amount of propellant gas if as ec-
ond deployment threshold is reached within a
few milliseconds.
The activation threshold of the Emergenc yT en-
sionin gD evices and the air bag are determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various point si n
the vehicle. This proces sisp re-emptive in
nature. Deploymen ts hould take place in good
time at the start of the collision.
The rat e
of vehicle deceleration or acceleration
and the direction of the forc ea re essentially
determined by: R
the distribution of forces during the collision R
the collision angle R
the deformation characteristic soft he vehicleR
the characteristic soft he objec tw ith which
the vehicle has collided
Factors which can only be seen and measured
after ac ollision has occurred do not play ad eci-
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 ifOccupant safety 49
Safety Z

only parts which are relatively easily deformed
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 ar esult.
If the control unit of the restraint system detects
as ide impact or av ehicle rollover, the relevant
components of the restraint system are activa-
ted separately depending on the anticipated
type of accident. R
Side impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt on the

The side impact air bag on the front-
passenger side deploys under the following
conditions: -

Head bags on the driver's and front-
passenger side in certain situations when the
vehicle rolls over, if the system determines
that deployment can offer additional protec-
tion to that provided by the seat belt
i Not 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-

Important safety notes
G WARNING
The function of the head restraint may be
impaired if you: R
attach object ss uch as coat hangers to the
head restraints, for example R
use head restraint covers
If you do so, the head restraint sc annot fulfill
their intended protective function in the event
of an accident .Ina ddition, object sa ttached
to the head restraint sc ould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any object stot he head
restraint sa nd do not use head restraint cov-
ers.
Method of operation NECK-PRO head restraint sr educe the likelihood
of head and chest injuries. The NECK-PRO head
restraint sont he driver's and front-passenger
seats are moved forwards and upwards in the
event of ar ear-end collision of ac ertain severity.
This provides better head support.
If the NECK-PRO head restraint sh ave been trig-
gered in an accident ,y ou must reset the NECK-
PRO head restraint sont he driver’s and front-
passenger seat ( Y
page 51). Otherwise, the
additional protection will not be available in the
event of another rear-end collision. You can rec-
ognize when NECK-PRO head restraint sh ave
been triggered by the fact that they have moved
forwards and can no longer be adjusted.
Mercedes-Benz recommends that you have the
NECK-PRO head restraint sc hecked for func-
tionality at aq ualified specialist workshop after
