The pretensioner helps the seat belt
to quickly restrain the occupant by
retracting the seat belt when the
vehicle is subjected to certain types
of severe frontal collision.
The front seat pretensioners also acti-
vate when the vehicle is subjected to
certain types of severe side collision.
The pretensioner does not activate in
the event of a minor frontal impact, a
minor side impact, a rear impact or a
vehicle rollover.
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.

■
Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■
Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is used
to hold the child restraint system (CRS) firmly. To free the belt again, fully retract the
belt and then pull the belt out once more. (
