frontal, side or rollover accidents. As a
result, the seatbelt restrains the front seat
occupant more effectively.
The front shoulder belt pretensioner in-
cludes a tension reducing device which
limits the peak forces exerted by the
seatbelt on the occupant in the event of a
collision.
The adaptive force limiter will reduce the
load to suit the body size of the occupant
as detected by the occupant detection
sensor (front passenger’s seatbelt).
! Lap belt pretensioner
S01AF0203
The shoulder belt pretensioner is supple-
mented by a lap belt pretensioner, which is
located at the base of the center pillar. The
lap belt pretensioner instantaneously pulls
the belt to eliminate slack if a certain level
of frontal collision force is detected. As a
result, the seatbelt restrains the front seat
occupant more effectively.

NOTE
This section is applicable to the follow-
ing components.
. second-row (window-side) seatbelt
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions or rollover accidents, any
seatbelt that has a seatbelt pretensioner is
quickly drawn back in by the retractor to
take up the slack so that the belt more
effectively restrains the seat occupant.
The second-row seatbelt (window-side)
pretensioners include a tension reducing
device which limits the peak forces 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 can not
be pulled out and retracted and therefore
must be replaced.
& System monitors
S01AF03
A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
with the ignition switch in the “ON” position.
The seatbelt pretensioners share the
control module with the SRS airbag
system. Therefore, if any malfunction
occurs in a seatbelt pretensioner, the
SRS airbag system warning light will
illuminate. For details, refer to “SRS airbag
system monitors” �P110.
