The seat belt pre-tensioner system includes the following com-
ponents:
The airbag control unit monitors the readiness of the electronic
parts of the system whenever the electric motor switch is in the
“ON” or “START” position. These include all of the items
listed above and all related wiring.
The pre-tensioner seat belt system will operate only when the
electric motor switch is in the “ON” or “START” position.
When the seat belt pre-tensioners activate, some smoke is
released and a loud noise will be heard. The smoke is not harm-
ful, but care should be taken not to intentionally inhale it, as it
may cause some temporary irritation to people with respiratory
problems.
The pre-tensioners activate in the event of a moderate-to-
severe front or side impact, even if the seat belt is not being
worn. The seat belt pre-tensioners may not activate in certain
frontal collisions, even though the vehicle may appear to be
severely damaged. Such non-activation does not mean some-
thing is wrong with the seat belt pre-tensioner system, but
rather that the collision forces were not severe enough or not of
the type to activate the system.
