Have the restraint system checked and
repaired in aqualified specialist workshop as
soon as possible.
PASSENGER AI RBAG indicator lamp
PASSENGER AIR BAG ON indicator lamp :and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS). The indicator lamp
sdisplay the status of the
front-passenge rfront air bag.
RPASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenge rfront air bag is
deployed.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deploye dinthe event of an acci-
dent.
Depending on the person in the front-passenger
seat, the front-passenge rfront air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during ajourney.
RChildren in achildr estraint system:
whethe rthe front-passenge rfront air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child .Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypag e49) and on "Chil-
dren in the vehicle" (Ypag e57). There you
wil lalsof ind instructions on rearward and
forward-facing child restraint systems on the
front-passenge rseat.
RAll other persons: depending on the classi-
ficatio nofthe person in the front-passenger
seat, the front-passenge rfront air bag is ena-
bled or deactivated (
Ypag e49). Be sure to
observe the notes on "Seat
belts“ (
Ypag e42) and "Air bags"
(Ypag e46). There you can als ofind infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicl eoccupants
in the event of an accident or the vehicl erolling
over. This reduces the risk of vehicl eoccupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt help stokeep the vehicle
occupant in the best position in relation to the
air bag.
42Occupant safety
Safety
The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or
turn the SmartKey to position1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident ,all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the status of the front-passenger front air bag changes while the vehicle is in motion,ana ir bag
display message appears in the instrument clus-
ter (
Ypage 229). When the front-passenger
seat is occupied, alwaysp ay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status
of the front-passenger front air bag both before
and during the journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. Aperson in the front-
passenger seat could then ,for example, come
into contact with the vehicle's interior, espe-
cially if the person is sittin gtoo close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
alwayse nsure that:
Rthe classification of the person in the front-
passenger seat is correcta nd the front-
passenger front air bag is enabled or disa-
bled in accordanc ewith the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure achild in arearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenger front air bag may deploy in an accident .The child could be
struck by the air bag. This poses an increased
risk of injury or even fatal injury.
Make sure that the front-passenger front 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 arear-
ward-facing child restraint system on the front-
passenger seat. You can find more information
on OCS under "Problems with the Occupant
Classification System" (
Ypage 53).
GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident ,the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe 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.
Always move the front-passenger seat as far
back as possible and fully retrac tthe seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt sash guide to the shoulder
