the front-passenger seat
The sensor system for the automatic child seat
recognition in the front-passenger seat detects
whether a special Mercedes-Benz child restraint
system with transponders has been fitted. In
this case, the PASSENGER AIR BAG OFF indica-
tor lamp lights up and remains lit. The front-
passenger front airbag is disabled.
i If the front-passenger front airbag is disa-
bled by the automatic child seat recognition,
the following remain enabled on the front-
passenger side:
R the sidebag
R the pelvisbag
R the windowbag
R the belt tensioner G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag has been disabled. The PASSENGER AIR-
BAG OFF indicator lamp must be lit. 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.
In this case the front-passenger seat may not be used. You may only transport a child on the
front-passenger seat if they are seated in a
suitable rearward or forward-facing child
restraint system. Always observe the infor-
mation about suitable positioning of the child restraint system in this Owner's Manual as
well as the child restraint system manufac-
turer's installation instructions. 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.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
seat-belt extender to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and down- Children in the vehicle

WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child
could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag 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.
Vehicles without automatic child seat
recognition on the co-driver's seat If the co-driver's seat of your vehicle is not
equipped with automatic child seat recognition,
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.
The PASSENGER AIR BAG OFF indicator lamp
lights up briefly when the key is turned to posi-
tion
2in the ignition lock. It has no function,
however, and does not indicate that the co-driv-
er's seat is equipped with automatic child seat
recognition.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps light
up briefly. They have no function, however, and do not indicate that the co-driver's seat is equip- ped with automatic child seat recognition.
Always fit the rearward-facing restraint system
to a suitable rear seat in this case (Y page 55).
Observe the following information under "Rear-
ward-facing child restraint system" and
"Forward-facing child restraint system" and on
suitable positioning of the child restraint system (Y page 55).
Rearward-facing child restraint system Warning symbol for a 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 37).
Always observe the information about suitable
positioning of the child restraint system
(Y page 55) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions. Children in the vehicle
