Windowbags
:are integrated in the side of the
roof frame and deploy in the area from the A-
pillar to the C-pillar.
When deployed, the windowbag enhances the
level of protection for the head. However, it does
not protect the chest or arms.
In the event of a side impact, the windowbag is
deployed on the side on which an impact occurs.
If the system determines that it can offer addi-
tional protection to that provided by the seat
belt, a windowbag may be deployed in other
accident situations (Y page 53).Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system on
the front-passenger seat, the automatic front-
passenger front airbag deactivation system cat- egorises the person in the front-passenger seat.Depending on that result, the front-passenger
front airbag is either enabled or disabled. If a
rearward-facing child restraint system is fitted
to the front-passenger seat, the PASSENGER
AIR BAG OFF indicator lamp must light up after
the system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the windowbag
R the seat belt tensioner
Make sure that your vehicle is equipped with the automatic front-passenger front airbag deacti-
vation system (Y page 60). If this is not the
case, always install a child restraint system on a
suitable rear seat (Y page 61).
If it is absolutely necessary to install a child
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. a
cushion. Fully retract the seat cushion length.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of a forward-
facing child restraint system must, as far as
possible, rest flat against the backrest of the
front-passenger seat. The child restraint system must not touch the roof or be put under strain bythe head restraint. Adjust the angle of the seat backrest and the head restraint position accord-
ingly. Only then is the correct function of the
automatic front-passenger front airbag deacti-
vation system guaranteed. Always observe the
information on suitable positioning of the child
restraint system (Y page 61) in addition to the
child restraint system manufacturer's installa-
tion instructions.
Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled. X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
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 airbag:
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
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 airbag. The PASSENGER AIR BAG OFF indi- cator lamp may be lit continuously or be off. Occupant safety
49Safety Z
If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears on the instrument
cluster (Y page 259). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front airbag both before and during the journey.
If a person sits in the passenger seat, he/she
must be:
R seated with the seat belt fastened correctly
R in an almost upright position with his/her
back against the seat backrest
R with his/her feet resting on the floor, if pos-
sible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers his/her weight by supporting him-
self/herself on a vehicle armrest
R sits in such a way that his/her weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag then does not
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa- bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child in a rearward-facing child
restraint system on the co-driver's seat and
the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag can deploy in the event of an accident. The child could be
struck by the airbag. There is an increased risk
of injury, possibly even fatal.
In this case, always make sure that the co-
driver's front airbag has been disabled. The
PASSENGER AIR BAG OFF indicator lamp
must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
Further information can be found under "Prob-
lems with the automatic front-passenger front
airbag deactivation system" (Y page 53). G
WARNING
If you secure a child in a forward-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:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt outlet to the shoulder belt 50

Possible causes/consequences and
M
MSolutions The PASSENGER AIR
BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or a per-
son with a build corre-
sponding to that of an
adult. The classification of the person on the front-passenger seat is false.
X Make sure the conditions for a correct classification of the person
on the front-passenger seat are met (Y page 49).
X If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.
X Have the automatic front-passenger front airbag deactivation sys-
tem checked immediately at a qualified specialist workshop. The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seatis:
R empty
R occupied with a rear-
ward-facing child
restraint system The automatic front-passenger front airbag deactivation system is
malfunctioning.
X Make sure there is nothing between the seat and the child restraint
system.
X Make sure that the entire base of the child restraint system rests on
the seat cushion of the front-passenger seat.
X Make sure that the seat cushion length is fully retracted.
X When installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight with the front-passenger

Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is not
equipped with the automatic front-passenger
front airbag deactivation system, this is indica-
ted by a special sticker. The sticker is affixed to
the side of the dashboard on the front-
passenger side. The sticker is visible when you
open the front-passenger door.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 61).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 61) and "Forward-facing child
restraint system" (Y page 61) as well as infor-
mation on the suitable positioning of the child
restraint system (Y page 61).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if
the PASSENGER AIR BAG OFF indicator lamp is lit continuously (Y page 42) is the front-
passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 61) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. Fully retract the seat cushion length. The entire base
of the child restraint system must always rest on the seat cushion of the front-passenger seat.
The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the front-passenger seat. The child restraint sys-tem must not touch the roof or be put under
strain by the head restraint. Adjust the angle of
the seat backrest and the head restraint posi-
tion accordingly. Always make sure that the
shoulder belt strap is correctly routed from the
vehicle belt sash guide to the shoulder belt
guide on the child restraint system. The shoul-
der belt strap must be routed forwards and
downwards from the belt sash guide. If neces-
sary, adjust the belt sash guide and the front-
passenger seat accordingly.

ance with ECE standards ECE R44 or ECE R129 (i-Size child restraint systems) are permitted foruse in the vehicle.
"Universal"-category child restraint systems can
be recognised by their orange approval label and the text "Universal" or an "i-Size" label. Children in the vehicle
61Safety Z
Example: approval label on the child restraint
system
The following "Universal"-category ISOFIX or i-
Size child restraint systems can be used on
seats labelled U, UF, IUF or i-U according to the
following tables:
R Suitability of the seats for attaching belt-
secured child restraint systems
R Suitability of the seats for attaching ISOFIX
child restraint systems
R Suitability of the seats for attaching an i-Size
child restraint system. Semi-universal child restraint systems are indi-
cated by the text "semi-universal" on the
approval label. These can be used if the vehicle
and the seat are listed in the child restraint sys-
tem manufacturer's vehicle model list. For fur-
ther information, contact the child restraint sys-
tem manufacturer or visit the manufacturer's
website.
If it is absolutely necessary to fit a child restraint system on the front-passenger seat:
X Always pay attention to the instructions under
"Child restraint system on the front-
passenger seat" (Y page 60).
There you will find instructions on how to cor-
rectly route the shoulder belt strap from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system (Y page 61).
X Move the front-passenger seat as far back as
possible and fully retract the seat cushion
length.
X Move the backrest to an almost vertical posi-
tion.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of a
forward-facing child restraint system must, as far as possible, rest flat against the backrest
of the front-passenger seat. The child
restraint system must not touch the roof or be
put under strain by the head restraint. Adjust the angle of the seat backrest and the head
restraint position accordingly. In addition,
observe the child restraint system manufac-
turer's installation instructions.
X Move the seat cushion angle to the highest,
most vertical position.
Suitability of the seats for attaching a belt-secured child restraint system If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of category
I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the child restraint system.
If you use a category I, forward-facing child restraint system, you should remove the head restraintfrom the respective seat, if possible (Y page 105). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forward
slightly.
For certain child restraint systems in weight categories II or III, this can mean that the area of use is restricted. The maximum size setting of the child restraint system may not be possible due to
possible contact with the roof.
Always observe the notes in the "Child restraint system" section (Y page 57) and the child restraint
system manufacturer's installation instructions. 62
