2020 MERCEDES-BENZ GLA ABS

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 in
the belt buckle ofthe front passenger seat
If the belt tongue isengaged inthe belt
buckle, theside impact airbag onthe front
passenger sidedeploys ifan appropriate acci-
dent situation occurs.Inthis case, deployment
is independent ofwhether thefront passenger
seat isoccupied ornot .
Window curtainairbags Window
curtainairbags 0043are integr atedinto
the side ofthe roof frame anddeployed inthe
area from theA-pillar tothe C-pillar.
When deployed, thewindow curtainairbag
enhanc esthe level ofprotec tionforthe head.
However, itdoes notprotec tthe chest or
arms.
If the restr aintsystem controlunit detect sa
side impact, thewindow curtainairbag is
deployed onthe side onwhich theimpact
occurs.
If the system determin esthat they canoffer
additional protectiontothat provided bythe
seat belt, awindow curtainairbag may be
deployed inother accident situations
(Y page 51). Occupant
Classification System
(OCS)
Introdu ction The
Occupant Classification System(OCS)cat-
egorizes theperson inthe front -passenger
seat. Dependin gon that result, thefront - passenger
frontairbag and front -passenger
knee bagareeither enabled ordeactivated.
The system doesnotdeactivate:
R the side impact airbag
R the window curtainairbag
R the Emergen cyTensionin gDevices
Requir ements To
be classified correctly,the front passenger
must sit:
R with theseat beltfasten edcorrec tly
R in an almost upright position withtheir back
against theseat backrest
R with their feetrestin gon the floor, ifpossi-
ble
If the front passenger doesnotobserve these
condit ions,OCSmayproduce afalse classifi-
cation, e.g.because thefront passenger:
R trans ferstheir weight bysupporting them-
selves onavehicle armrest
R sits insuch away that their weight israised
from theseat cushion
If it is absolutely necessarytoinstall achild
restr aintsystem onthe front -passenger seat,
be sure toobserve thecorrec tpositionin gof
the child restraintsystem. Neverplaceobject s
under orbehind thechild restraintsystem, e.g.
a cushion. Theentir ebase ofthe child
restr aintsystem mustalway srest onthe seat
cushion ofthe front -passenger seat.Theback-
rest ofthe forward-fac ingchild restraintsys-
tem must lieasflat aspossible againstthe
backrest ofthe front -passenger seat.
The child restraintsystem mustnottouch the
roof orbe subject edtoaload bythe head
restr aint. Adjust theangle ofthe seat backrest
and thehead restraintposition according ly.
Only thencanOCS beguaranteed tofunct ion
correc tly.Always observe thechild restraint

If
it is absol utely necessary tocarry achild on
the front passe ngerseat, besure toobserve
the information onthe "Occupa ntCla ssifica -

R U.S. Federal MotorVehicle SafetyStandards
213 and225

Confirma tionthat thechild restraint system
corresponds tothe standards canbefound on
an instruction labelon the child restraint sys-

WARNING
For LATCH-type (ISOFIX)childrestraint sys-
tems inwhich thechild issecured usingthe
safety beltintegrated inthe child restraint
system, themaximum permissibleweig htof
the child andchild restraint systemtogether
is 73 lbs (33 kg).
If the child andthechild restraint system
together weighmore than73lbs (33 kg),the
LATCH-type (ISOFIX)childrestraint system
with integrated safetybeltnolonger offers
sufficie ntprotection. TheLATCH-type (ISO-
FIX) child seatsecuring systemmaybeover-
load ed,and thechild maynotberestrained

increased riskofinjury oreven fatalinjury.
If the child andthechild restraint system
together weighmore than73lbs (33 kg),
use only aLATCH-type (ISOFIX)child
restraint systeminwhich thechild isalso
secured withthevehicle seatbelt. Also
secure thechild restraint systemwiththe
