1-4. Adjustable components (seats, mirrors, steering wheel) n Adjusting the seat belt shoulder anchor height (front seats) Push the seat belt shoulder anchor down while pressing the release button. Push the seat belt shoulder anchor up. Move the height adjuster up and down as needed until you hear a click. Seat belt pretensioners (front 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. Pre-collision seat belts (front seats of vehicles with pre-collision system) If the pre-collision sensor detects that a collision is unavoidable, the pre-collision system will retract the seat belt, thus enhancing the effectiveness of the seat belt pretensioner in a crash. The same will happen if the driver makes an emergency braking or loses control of the vehicle. (→P. 257) 86 PRIUS_U (OM47685U) DVD
