Sonata Plug-in Hybrid main systems
Seat Belt Pretensioners
The Sonata Plug-
in Hybrid is equipped with driver’s and front passenger’s seat belts with
pretensioners. When the seat belt pretensioners are activated in a collision, a loud noise may be
heard and fine dust, which may appear to be smoke, may be visible in the passenger
compartment. These are normal operating conditions and are not hazardous. The seat belt
pretensioner assembly mechanisms may become hot during activation, and may need several
minutes to cool after they have been activated.
Sensors and Control Module
The airbags and pretensioners are managed by the SRS Control Module, or SRSCM, which is
located below the front of the center console. In addition, there are four side impact sensors :
two conventional accelerometer sensors in the B-pillars, and two pressure sensing sensors
inside of the front door modules. Their locations are illustrated in the image below.
