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
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec-
essary, adjust the vehicle belt sash guide and the front-passenger seat accordingly. Always
observe the information about suitable posi-
tioning of the child restraint system in this
Owner's Manual as well as the child restraint system manufacturer's installation instruc-
tions.
i Ensure that your vehicle is equipped with
automatic child seat recognition for the
front-passenger seat (Y page 61). If this
is not the case, always fit the child restraint
system on a suitable rear seat
(Y page 63). PASSENGER AIR BAG OFF indicator lamp
:
shows you whether the front-passenger front airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock, or press the Start/Stop button once
or twice on vehicles with KEYLESS-GO.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp
R is lit, the front-passenger front airbag is
disabled. They will then not be deployed in
the event of an accident.
R is not lit, the sensor system did not detect
a child restraint system with transponder
for automatic child seat recognition. If, in
the case of an accident, all deployment cri-
teria are met, the front-passenger front air-
bag is deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of thefront-passenger front airbag both before and
during the journey. 60
