belt, a windowbag may be deployed in other
accident situations (Y page 51).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 57). If this is not the
case, always install a child restraint system on a
suitable rear seat (Y page 59).
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 59) 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.
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 226). 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. Occupant safety

following conditions:
- an occupant is detected in the front-
passenger seat or
- the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
R Windowbag on the side on which an impact
occurs, independently of seat belt usage and
regardless of whether the front-passenger
seat is occupied
R Seat belt tensioners, if the system determines
that deployment can offer additional protec-
tion for the vehicle occupants in this situation
i Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other.
How the airbag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:

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 outlet to the shoulder belt guide on the child restraint system. The shoulder belt
strap must be routed forwards and downwards
from the vehicle belt outlet. If necessary, adjust
the vehicle belt outlet and the front-passenger
seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 59) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems approved in accord-
ance with ECE standards ECE R44 or ECE R129 (i-Size child restraint systems) are permitted for
use in the vehicle.
For certain child restraint systems in weight cat- egories 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.
"Universal" category child restraint systems can
be recognised by their orange approval label and the text "Universal" or an "i-Size" label. Example: approval label on the child restraint
system
ISOFIX or i-Size child restraint systems of the
“Universal“ category can be used on seats label- led U, UF, IUF or i-U in accordance with the fol-
lowing 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 more
information, contact the child restraint system
manufacturer or visit their website.

length.
If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
you must also move the front-passenger seat to the highest position.
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 the
forward-facing child restraint system must, as far as possible, be resting on 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. Also observe
the child restraint system manufacturer's
installation instructions.
X If possible, move the seat cushion angle to the
highest, most vertical position (Y page 98).
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 100). 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.
