. Side impact sensor
. Front door impact sensor
. Rollover sensor
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 driver’s seatbelt pretensioner includes
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.
! In cases of rollover accident, frontal
collisions or side collisions, the
following components will operate
simultaneously
S01AF0101
For details, refer to “In cases of rollover
accident, frontal collisions or side colli-
sions, the following components will oper-
ate simultaneously” F1-23.
& Seatbelt with shoulder belt
and lap belt pretensioners
S01AF02
NOTE
This section is applicable to the front
passenger’s side seatbelt.
1) Seatbelt retractor assembly (shoulder
belt pretensioner and adaptive force
limiter)
2) Lap belt pretensioner
On the front passenger’s side, the
shoulder belt pretensioner is supplemen-
ted by a lap belt pretensioner, which is
located at the base of the center pillar. Like
the shoulder belt pretensioner, the lap belt
pretensioner instantaneously pulls in 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.
The front passenger’s seatbelt preten-
sioner includes 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 select a
reducing load to the suit body size of
occupant as detected by the occupant
detection sensor.
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.
