correct use of the child restraint system
(Y page 62).
Before every trip, make sure that the ISOFIX
child restraint system is engaged correctly in
both ISOFIX securing rings. X
Install the ISOFIX child restraint system on
both ISOFIX securing rings :.
ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. The ISOFIX securing rings for two ISOFIX child restraint systems are fitted on the
left and right of the rear seats.
Non-ISOFIX child seats may also be used and
can be installed using the vehicle's seat belt
system. When fitting a child restraint system, besure to observe the manufacturer's installation
and operating instructions and the instructions
for correct use of the child restraint system
(Y page 62). Child restraint system on the front-
passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in the front seats. For this reason, Mercedes-
Benz strongly advises that you fit a child
restraint system on a rear seat.
Vehicles with the automatic co-driver's front air-
bag deactivation system: if it is absolutely nec-
essary to fit a child restraint system to the co-
driver's seat, always observe the notes on the
"Automatic co-driver's front airbag deactivation system" (Y page 50). You can thus avoid the risks that could arise as
a result of:
R a child restraint system that is not detected
by the automatic co-driver's front airbag
deactivation system
R the unintentional disabling of the co-driver's
front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the co-
driver's sun visor, see the illustration. 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.
NEVER use a rearward-facing child restraint on a
seat protected by an ACTIVE AIRBAG in front of it, DEATH or SERIOUS INJURY to the CHILD can
occur.
If the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag is activated
(Y page 43). Children in the vehicle

Vehicles without automatic co-driver's
front airbag deactivation system If the co-driver's seat of your vehicle is not
equipped with an automatic co-driver's front air-
bag deactivation system, this is indicated by a
special sticker. The sticker is affixed to the side of the dashboard on the co-driver's side. The
sticker is visible when you open the co-driver's
door.
Never fit a rearward-facing child restraint sys-
tem to the co-driver's seat in this case
(Y page 62).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 62) and "Forward-facing child
restraint system" (Y page 62) and on suitable
positioning of the child restraint system
(Y page 62).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the co-driver's
seat, you must always make sure that the co-
driver's front airbag is deactivated. The co-driv-
er's front airbag is only disabled if the
PASSENGER AIRBAG OFF indicator lamp is lit
continuously (Y page 43).
Always observe the information about suitable
positioning of the child restraint system
(Y page 62) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions.
Forward-facing child restraint system If it is absolutely necessary to secure a child in a
forward-facing child restraint system on the co- driver's seat, you must always move the co-driv-
er's seat as far back as possible. Fully retract the
seat cushion length. The base of the child restraint system must lie fully on the co-driver's
seat cushion. The backrest of the child restraint
system must lie as flat against the co-driver's
seat backrest as possible. The child restraint
system may 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 vehicle belt outlet. If nec-
essary, adjust the vehicle belt sash guide and
the co-driver's seat accordingly.
Always observe the information about suitable
positioning of the child restraint system
(Y page 62) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems that are approved in
accordance with ECE standard ECE R44 are per-
mitted for use in the vehicle.
"Universal"-category child restraint systems can be recognised by their orange approval label and
the text "Universal". Example: approval label on the child restraint
system
The following "Universal"-category child
restraint systems can be used on seats labelled
U, UF or IUF according to the tables "Suitability
of the seats for attaching a belt-secured child
restraint system" or "Suitability of the seats for
attaching an ISOFIX child restraint system". 62

Suitability of the seats for attaching an ISOFIX 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.
In addition, always observe the notes under "Child restraint system" (Y page 60) and the child
restraint system manufacturer's installation instructions.
Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forwards 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.
When the soft top is opened and closed, child restraint systems of weight categories II or III must be removed or the head restraint of the child restraint system must be set to the lowest position.
Legend for the table:
XI SOFIX position that is not suitable for ISOFIX child restraint systems in this weight category
and/or size category.
IUF Suitable for forward-facing ISOFIX child seat securing systems that belong to the "Universal" category and are approved for use in this weight category.
IL Suitable for ISOFIX child restraint systems as recommended; see the "Recommended child restraint systems" table (Y page 65).
The manufacturer will also recommend a suitable ISOFIX child restraint system. For this, your
vehicle and the seat must be listed in the child restraint system manufacturer's model list. For more information, contact the child restraint system manufacturer or visit the manufacturer'swebsite. Weight category Size cate-

Owner's Manual The front-passenger front airbag and front-passenger kneebag are
disabled during the journey, although:
R An adult
or
R A person of the corresponding stature is on the front-passenger
seat
If additional forces are applied to the seat, the weight the system
detects may be too low.
G WARNING
The front-passenger front airbag does not deploy during an accident.
This poses an increased risk of injury!
X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Secure the vehicle against rolling away (Y page 159).
X Switch the ignition off.
X Have the front passenger step out of the vehicle.
X Make sure that the seat is unoccupied, close the front-passenger
door and switch on the ignition.
X Observe the PASSENGER AIR BAG indicator lamps on the centre
console and the multifunction display and check the following:
Seat unoccupied and ignition switched on:
R A self-diagnosis is carried out. The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps must light up simulta-
neously for approximately six seconds
R The PASSENGER AIR BAG OFF indicator lamp must then light up
and remain lit after the self-diagnosis. If the indicator lamp is on,
