onds after the vehicl eisstarted. The compo-
nents of the restraint system are in operational

system components may be triggeredu nin-
tentionall yormight not be triggeredata ll in
the event of an accident with ahigh rate of
vehicl edeceleration. This can affect the Emer-
gency Tensioning Device or air bag ,for exam-
ple. This poses an increase drisk of injury or

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.
