regular intervalswhile the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignitio nis
switched on. It goes out no later than afew sec-
onds after the vehicleiss tarted. The compo-
nents of the restraint system are in operational
readiness.
Am alfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignitio nisswitched
on
Rdoes not go out after afew seconds with the
engine running
Rlights up again while the engine is running
GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for examplet he Emergency Tensioning
Device or the air bag .This poses an increased
risk of injury or even fatal injury.
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 for 60 sec-
onds, subsequently both indicator lamp sare
off (PASSENGER AIR BAG ON and OFF): the
front-passenge rfront air bag is abl etodeploy
in the event of an accident.
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.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag .The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
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:
whethert he 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.T herefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypag e45) and on "Chil-
dren in the vehicle" (Ypag e53). 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 e45). Be sure to
observe the notes on "Seat
belts“ (
Ypag e39) and "Air bags"
(Ypag e43).T here 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 vehicleo ccupants
in the event of an accident or the vehicler olling
over. This reduces the risk of vehicleo ccupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helpstok eep the vehicle
