Front seatbelt pretensioners

The driver

’s and front passenger’s seat-

belts have a seatbelt pretensioner. The
seatbelt pretensioners are designed to be
activated in the event of an accident
involving a moderate to severe frontal
collision.

NOTE

This section is applicable to the follow-
ing components.
. Except XV CROSSTREK models:

– Driver’s side seatbelt

– Front passenger’s side seatbelt

. XV CROSSTREK models:

– Driver’s side seatbelt

The pretensioner sensor also serves as
the frontal SRS airbag sensor. If the
sensor detects a certain predetermined
amount of force during a frontal collision,
the front seatbelt is quickly drawn back in
by the retractor to take up the slack so that
the belt more effectively restrains the front
seat occupant.

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 can not
be pulled out and retracted and therefore

must be replaced.

NOTE

. Seatbelt pretensioners are not de-
signed to activate in minor frontal
impacts, in side impacts or in rear
impacts.

. In the case of rollover accidents
