Front seatbelt with shoulder
belt and lap belt pretension-
ers
1) Seatbelt retractor assembly (shoulder
belt pretensioner)
2) Lap belt pretensioner
If the SRS airbag sensors detect a certain
predetermined amount of force during a
frontal or side collision, the front seatbelt
is quickly drawn in by the pretensioner to
take up the slack so that the belt more ef-
fectively restrains the front seat occupant.
The driver’s and front passenger’s
seatbelt pretensioner includes a tension
reducing device which limits the peak forc-
es exerted by the seatbelt on the occupant
in the event of a collision.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a
small amount of smoke will be released.
These occurrences are normal and not
harmful. This smoke does not indicate a
fire in the vehicle.
Once the seatbelt pretensioner has been
activated, the seatbelt retractor remains
locked. Consequently, the seatbelt cannot
be pulled out and retracted and therefore
must be replaced.
