1-3. Adjustable components (seats, mirrors, steering wheel) Pre-collision seat belts (front seats of vehicles with pre-collision system) If the pre-collision sensor detects that a collision is unavoidable, the precollision safety system will retract the seat belt using a motor, 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. 193) 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 or pull out the belt too quickly. Allow the belt to fully retract, and then slowly extend the belt. If the belt cannot be pulled out of the retractor, firmly pull the belt and release it. You will then be able to smoothly pull the belt out of the retractor. 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, fully retract the belt and then pull the belt out once more. (→P. 112) n Pregnant women Obtain medical advice and wear the seat belt in the proper way. (→P. 60) 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 rounding of the abdominal area. If the seat belt is not worn properly, not only a pregnant woman, but also the fetus could suffer death or serious injury as a result of sudden braking or a collision. 62
