1-3. Adjustable components (seats, mirrors, steering wheel) Seat belt pretensioners (front, second outboard 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 pretensioner may not activate in the event of a minor frontal impact, a side impact or a rear impact. s Pre-collision seat belts (front seats of vehicles with pre-collision system) When operating in the event of sudden braking, the seat belts lessen collision injury by retracting the slack in the front seat belts before the collision, thus restraining the driver and passenger at an earlier stage. (→P. 272) n 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. 88
