Risk of injury
If the front-passenger front airbag is not
disabled:
R a child secured in a child restraint system
on the front-passenger seat could be
seriously and even fatally injured by the
front-passenger airbag deploying. This is
especially likely if the child is in the imme-
diate vicinity of the front-passenger front
airbag when it is deployed.
R a child must never be secured on the
front-passenger seat in a rearward-facing
child restraint system. Only secure a rearward-facing child restraint system on
a suitable rear seat.
R always move the front-passenger seat to
the rearmost position if you secure a
child in a forward-facing child restraint
system on the front-passenger seat.
The front-passenger front airbag is not dis-
abled:
R on vehicles without automatic child seat
recognition in the front-passenger seat*
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat* if
there is no child restraint system with
automatic child seat recognition fitted to
the front-passenger seat.
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat* if
the 5 PASSENGER AIRBAG OFF warn-
ing lamp is not lit.
To draw attention to this danger, there is an
appropriate warning sticker on the dash-
board as well as on both sides of the sun
visor on the front-passenger side. Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat*
If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. It is visible when
you open the front-passenger door.
The warning lamp 6
is located on the centre
console. 1

The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with auto-
matic child seat recognition has been fitted.
In such cases, 5PASSENGER AIRBAG
OFF indicator lamp 1lights up. The front-
passenger airbag is deactivated. G
Risk of injury
If the 5 PASSENGER AIRBAG OFF warn-
ing lamp does not light up when the child
restraint system is fitted, the front-
passenger front airbag has not been disa-
bled. If the front-passenger front airbag is
deployed, the child could be seriously or
even fatally injured.
Proceed as follows:
R do not use a rearward-facing child
restraint system on the front-passenger
seat.
R fit a rearward-facing child restraint sys-
tem on a suitable rear seat. or
R
only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to its rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist work-
shop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions correctly, never place objects (such
as a cushion) under the child restraint sys-
tem. The entire base of the child restraint
system must always rest on the seat cush-
ion. An incorrectly fitted child restraint sys-
tem cannot perform its intended protective
function in the event of an accident, and
could lead to injuries.
i The windowbag, the sidebag and the belt
tensioner on the front-passenger side are still active even when the front-passenger
front airbag is disabled. G
Risk of injury
Do not place items of electronic equipment
on the front-passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes
or access cards
Signals from electronic equipment can
cause interference in the automatic child
seat recognition sensor system. This can
lead to a system malfunction. This may
cause the 5PASSENGER AIRBAG OFF
warning lamp to light up without there
being a child seat with automatic child seat
recognition fitted. This means that the
front-passenger airbag is not deployed dur-
ing an accident. It is also possible that the
5 PASSENGER AIRBAG OFF warning
lamp will not light up briefly if you turn the
key in the ignition lock to position 2.Safety

The steering wheel heating* indi-
cator lamp on the lower left lever
of the steering column is flashing. There is insufficient voltage
because too many consumers are
switched on. The steering wheel
heating* has switched itself off
automatically. X
Switch off consumers that are not required, e.g. reading lamps,
interior lighting, etc.
The steering wheel heating* will automatically switch back on as
soon as there is sufficient voltage again. The indicator lamp in the
