& Seatbelt with shoulder belt
and lap belt pretensioners
NOTE
This section is applicable to the front
passenger’sseatbeltinXVCROSS-
TREK models.
1) Seatbelt retractor assembly (shoulder
belt pretensioner)
2) Lap belt pretensioner
On the front passenger’ssideinXV
CROSSTREK models, the shoulder belt
pretensioner is supplemented by a lap belt
pretensioner, which is located at the base
of the center pillar. Like the shoulder belt
pret ensioner, the lap belt prete nsioner
instantaneously pulls in the belt to elim-
inate slack if a certain level of frontal
collision force is detected. As a result, the
seatbelt restrains the front seat occupant
more effectively.
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 pretensioner re-
mains locked. Consequently, the seatbelt
cannot be pulled out and retracted and
therefore must be replaced.
NOTE
. Seatbelt pretensioners are not de-
signed to activate in minor impacts or
in rear impacts.
. When a rollover accident occurs, the
lap belt pretensioner does not activate;
however, as the curtain airbags deploy,
the shoulder belt pretensioner is acti-
vated. At this time, the driver’s side
seatbelt pretensioner and passenger ’s
side shoulder belt pretensioner acti-
vate simultaneously.
. In cases of frontal collisions, the
following components will operate si-
multaneously.
– Seatbelt pretensioner for driver
– Seatbelt pretensioner for front
passenger
– SRS frontal airbag for driver
– SRS frontal airbag for front pas-
senger*
– SRS side airbags (both sides) (if
an offset frontal collision occurs)
– SRS curtain airbags (both sides)
(if an offset frontal collision occurs)
*: This does not operate if the occupant
detection system deactivates airbag op-
eration. For details, refer to “Front
passenger’s SRS frontal airbag” F1-46
.
. In cases of side collisions, the
following components will operate si-
multaneously.
– SRS curtain airbag (impacted
side)
– SRS side airbag (impacted side)
(when any of the center pillar im-
pact sensors/front door impact sen-
sors sense an impact force)
– Seatbelt pretensioner for driver
(when the driver’s side front door
impact sensor sense an impact
force)
– Seatbelt pretensioner for front
passenger (shoulder belt preten-
sioner only) (when the front pas-
senger ’s side front door impact
sensor sense an impact force)
. Pretensioners are designed to func-
