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 ignition switch is in the “ON”
or “START” position. These include all of the items listed
above and all related wiring.
The seat belt pre-tensioners will operate only when the ignition
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 whenever a moderate-to-serve
impact is applied to the front or side of the vehicle, even if the
seat belt is not being worn. The seat belt pre-tensioners may
not activate in certain collisions, even though the vehicle may
appear to be severely damaged. Such non-activation does not
mean that something is wrong with the seat belt pre-tensioner
system, but rather that the collision forces were not severe
enough to activate the system.
