. Front passenger s seatbelt
. R e a r w i n d o w - s i d e s e a t b e l t ( i f

to be activated in the event of an accident
involving a moderate to severe frontal or
side collision.
Seat, seatbelt and SRS airbags/Seatbelt pretensioners
& Front seatbelt with shoulder
belt and lap belt preten-
sioners
1) Seatbelt retractor assembly (shoulder
belt pretensioner and adaptive force
limiter (if equipped))
2) Lap belt pretensioner
The pretensioner sensor also serves as
follows.
. SRS frontal airbag sensor
. Side impact sensor
. Front door impact sensor
. Rollover sensor (Russia models only)
If the sensor detects a certain predeter-
mined 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 effectively
restrains the front seat occupant.
The driver s and front passenger s seat-
belt pretensioner includes a tension redu-
cing device which limits the peak forces
exerted by the seatbelt on the occupant in
the event of a collision.
. Adaptive force limiter (if equipped)
The driver s side adaptive force limiter will
select a reducing load to the suit body size
of occupant as detected by the driver s
seat position sensor.
The front passenger s side 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 acti-
vated
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.
