Seat Belt Pretensioners
If the vehicle has seat-mounted side
impact airbags and roof-rail airbags,
it also has seat belt pretensioners
for the front outboard occupants.
Although the seat belt pretensioners
cannot be seen, they are part of the
seat belt assembly. They can help
tighten the seat belts during the
early stages of a moderate to
severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met.
And, if the vehicle has roof-rail
airbags, seat belt pretensioners can
help tighten the seat belts in a side
crash or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle s seat belt
system will need to be replaced.

damage the webbing and hardware.

outboard seating positions of

stored in a pocket on the side of the
seatback.
