Seat belt pretensioners (front and outboard rear seats)

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.

Pre-collision seat belts (front seats of vehicles with pre-collision

If the pre-collision sensor detects that a collision is unavoidable, the pre-

collision system will retract the seat belt before the collision occurs.

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.

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. (P. 61)
