Solutions
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 48).
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 as soon as possible at a Mercedes-Benz Service
Centre.
The PASSENGER AIR
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seat
is:
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
seat adjustment. This could result in the seat belt and the child
restraint system being pulled too tightly.
X
Check that the child restraint system is installed correctly.
X
Make sure that no objects are applying additional weight to the
seat.

If the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install
a rearward-facing child restraint system on the front-passenger
seat. It is recommended that you fit the child restraint system to a
suitable rear seat.

Have the automatic front-passenger front airbag deactivation sys-
tem checked as soon as possible at a Mercedes-Benz Service
Centre.
Deployment of belt tensioners and air-

Important safety notes
G
WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible.
G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
