inthe vehicle interior mayprevent
an air bag from functioning correctly.Before
start ingyour journ eyand toavoid risksresulting
from thespeed ofthe airbag asitdeploys, make
sure that:
R there arenopeople, animals orobject s

R there arenohard object s,e.g. coat hangers,

If you modify theairbag cover oraffix object s

Sens orstocont rolthe airbags arelocated in
the doors. Modification sor work notper-
formed correctly tothe doors ordoor panel-

Never modify thedoors orparts ofthe doors.
Always havework onthe doors ordoor pan-

Front airbags !
Do
not place heavy objectson the fron t-

to identif ythe seat asbeing occupied. Inthe
event ofan accident ,the restr aintsystems onthe
fron t-passenger sidemay betrigger ed
and have tobe replaced. Driver

deploys infron tof and above theglove box.
When deployed, thefron tair bags offeraddi-

pants inthe fron tseats.
The PASSENGER AIRBAG OFFindicato rlamp

passenger frontair bag (Ypage 41).
The front-passenger frontair bag willonly
deploy if:
R the system, basedonthe OCS weight sensor

Unsuitable seatcovers canobstruct orpre-
vent deployment ofthe airbags integr ated

cann otprotec tvehicle occupant sas they are

the occupant classification system(OCS)

increased riskofinjury oreven fatalinjury.
You should onlyuseseat covers thathave
been approved forthe respect iveseat by
Mercedes- Benz. Fron
tside impact airbags 0043and rear side
impact airbags 0044deploy nexttothe outer bol-

When deployed, theside impact airbag offers
additional thoraxprotection.Italso offers addi-

front seats. However, itdoes notprotec tthe:
R Head
R Neck

If the restr aintsystem controlunit detect sa side
impact, theside impact airbag isdeployed on
the side onwhich theimpact occurs.
The side impact airbag onthe front -passenger
side deploys underthefollowing conditions:
R the OCS system detectsthat thefront -
passenger seatisoccupied or
R the seat beltbuckle tongue isengaged inthe
belt buckle ofthe front -passenger seat If
the belt tongue isengaged inthe belt buckle,
the side impact airbag onthe front -passenger

or not .
