Pre-Safe; System - Mercedes-Benz A-Class Owner's Manual

42 Occupant safety
with a build corresponding to that of an adult
should not use the front passenger seat.
Instead, they should use a rear seat.
If the front passenger seat is occupied by a
R
person of smaller stature (e.g. a teenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp either lights up continuously
or remains off, depending on the result of the
classification.
If the PASSENGER AIR BAG OFF indicator
-
lamp is off: move the front passenger
seat as far back as possible, or the per‐
son of smaller stature should use a rear
seat.
If the PASSENGER AIR BAG OFF indicator
-
lamp is lit continuously: the person of
smaller stature should not use the front
passenger seat.
& WARNING Risk of injury or death when
the PASSENGER AIR BAG OFF indicator
lamp is lit
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test,
the front passenger airbag is disabled. It will
not be deployed in the event of an accident.
In this case, the front passenger airbag can‐
not perform its intended protective function,
e.g. when a person is seated in the front
passenger seat.
That person could, for example, come into
contact with the vehicle interior, especially if
the person is sitting too close to the cockpit.
If the front passenger seat is occupied,
always ensure that:
The classification of the person in the
R
front passenger seat is correct and the
front passenger airbag is enabled or disa‐
bled in accordance with the person in the
front passenger seat.
The person is seated properly with a cor‐
R
rectly fastened seat belt.
The front passenger seat has been moved
R
as far back as possible.
