Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat 1
5 PASSENGER AIRBAG OFF warning
lamp
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, the 5PASSENGER AIRBA G
OFF indicator lamp 1lights up. The front -
passenger airbag is deactivated. G
Risk of injury
If the 5PASSENGER 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-passenge r
seat.
or
R Only use a forward-facing child seat on
the front-passenger seat and move the
front-passenger seat to its rearmost
position.
R Have the automatic child seat recogni-
tion checked at a qualified specialist
workshop .
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 be resting on the seat
cushion. An incorrectly fitted child restraint system cannot perform its intended pro-
tective function in the event of an accident
,
and could even lead to injuries .
i The head/thorax airbag and the belt ten-
sioner on the front-passenger side are still
active even if the front-passenger front air-
bag is disabled. G
Risk of injury
Do not place items of electronic equipment
on the front-passenger seat, e.g.:
R laptops, if switched on
R mobile phones
R cards with transponders, e.g. ski passe s
or access passes
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 the front-
passenger airbag is not deployed during an
accident. It is also possible that the
