Safety
Restraint system control unit
The smart is equipped with an electronic control unit which
triggers restraint systems depending on the expected impact
severity. On the USA and Canada national versions, two up-
front sensors are installed additionally on the flexural mem-
ber at the front end.
In order to better detect side impacts, the central crash sen-
sor is supported by satellite sensors in the area of the B-pillar
base and by pressure sensors in the front doors.
Depending on the seat occupancy detection status and seat
position detected via the seat position switch, the seat occu-
pied recognition system can suppress or adjust airbag trigge-
ring on the passenger side on the USA and Canada national
versions. Seat position switches control the switchable belt
force limiters and activation of the ventilation valve by a squib
in the front passenger airbag.
A seat belt buckle switch monitors the belt status at each
position: "engaged" or "not engaged". A visual/acoustic seat
belt reminder warning function is provided for the two front
seats depending on the country. The indicator lamp is loca-
ted in the instrument cluster. The front passenger seat has a
seat belt reminder mat. The indicator lamp for the rear seats
is located in the overhead control panel.
