1-4. Adjustable components (seats, mirrors, steering wheel) Pre-collision seat belts (front seats of vehicles with a pre-collision system) If the pre-collision sensor detects that a collision is unavoidable, the precollision 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. 260) 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. To allow the belt to extend, retract the belt and then pull it slowly. n 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, press the buckle release button and fully retract the seat belt. (→P. 143) n Pregnant women Obtain medical advice and wear the seat belt in the proper way. (→P. 89) Women who are pregnant should position the lap belt as low as possible over the hips in the same manner as other occupants. Extend the shoulder belt completely over the shoulder and position the belt across the chest. Avoid belt contact over the round part of the abdominal area. If the seat belt is not worn properly, not only the pregnant woman, but also the fetus could suffer death or serious injury as a result of sudden braking or a collision. 92
