Mitsubishi ECLIPSE Owner's Manual page 58

The seat belt pre-tensioner system includes the following com-
ponents:
1- SRS warning light
2- Front impact sensors
3- Seat belt pre-tensioners
4- Seat belt buckle switches
5- Air bag control unit
The air bag 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 pre-tensioner seat belts 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.
Even in the event of a severe frontal impact, the pre-tensioners
will not operate if the seat belts are not fastened. 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 something 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.
WARNING
!
The seat belt pre-tensioner system is designed to
work only once. After the seat belt pre-tensioners
have been activated, they will not work again. They
must promptly be replaced and the entire seat belt
pre-tensioner system inspected by an authorized
Mitsubishi Motors dealer.
