Seat belt pretensioners (front seats)
The pretensioners help the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal
collision.
The pretensioners do not activate
in the event of a minor frontal
impact, a side impact, a rear
impact or a vehicle rollover.
Pre-collision seat belts (front seats of vehicles with pre-collision
system)If the pre-collision sens or detects that a collision is unavoidable, the
pre-collision system will retract the seat belt, thus enhancing the
effectiveness of the seat be lt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (P. 340)
■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. ( P. 196)
