system warning lamp: R
does not light up after the ignition is switched
on R
does not go out after af ew seconds with the

G WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident .T his can affect
for example the 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 aq ualified specialist workshop as
soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp C and
PASSENGER AIR BAG OFF indicator lamp D are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag. R
PASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident ,a ll deployment criteria are met, the front-passenger front air bag is
deployed. R
PASSENGER 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.
Dependin gont he person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during aj ourney.R
Children in ac hild restraint system:
whether the front-passenger front 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)" ( Y
page 44) and on "Chil-
dren in the vehicle" ( Y
page 51). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat. R
All other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated ( Y
page 44). Be sure to
observe the notes on "Seat
belts“ ( Y
page 38) and "Air bags"
( Y
page 42). There you can also find infor-
mation on the correc ts eat position.
Seat belts
Introduction Seat belts are the most effective means of
restrictin gt he movemen tofv ehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises: R
Seat belts R
Emergency Tensionin gD evices and seat belt
force limiters
If the seat belt is pulled by the belt loop quickly
or with aj erk ym ovement, the belt retractor
locks. The belt strap cannot be extracted any
further.38
Occupant safety
Safety

If the front passenger does not observe these
conditions, OCS may produce af alse classifica-
tion, e.g. because the front passenger: R
transfers their weight by supporting them-
selves on av ehicle armrestR
sits in such aw ay that their weight is raised
from the seat cushion
If you install ac hild restraint system on the
front-passenger seat, be sure to observe the
correct positioning of the child restraint system.
Never place objects under or behind the child
restraint system, e.g. ac ushion. The entire base
of the child restraint system must always rest on
the seat cushio noft he front-passenger seat.
The backrest of the forward-facing child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat.
The child restraint system must not touch the
roof or be subjected to al oad by the head
restraint. Adjust the angle of the seat backrest
and the head restraint positio na ccordingly.
Only then can OCS be guaranteed to function
correctly. Alway so bserve the child restraint sys-
tem manufacturer's installation and operating
instructions.

Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The indicator lamp on
the l button flashes.
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The on-board voltage is too low because too many electrical consum-
ers are switched on. X
Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window defroster
can be activated again.
The roof is open. X
Close the roof.
When the roof is closed, the rear window defroster can be activated
again.
Switching air-recirculation mode
