SEAT BELTS ● Do not attach anything to the head restraint stalks. Doing so could impair active head restraint function. The active head restraint moves forward utilizing the force that the seatback receives from the occupant in a rear-end collision. The movement of the head restraint helps support the occupant's head by reducing its backward movement and helping absorb some of the forces that may lead to whiplash-type injuries. Active head restraints are effective for collisions at low to medium speeds in which it is said that whiplash injury occurs most. Active head restraints operate only in certain rear-end collisions. After the collision, the head restraints return to their original positions. Properly adjust the active head restraints as described in this section. SSS0136 PRECAUTIONS ON SEAT BELT USAGE If you are wearing your seat belt properly adjusted and you are sitting upright and well back in your seat with both feet on the floor, your chances of being injured or killed in a collision and/or the severity of injury may be greatly reduced. NISSAN strongly encourages you and all of your passengers to buckle up every time you drive, even if your seating position includes a supplemental air bag. Most U.S. states and Canadian provinces or territories specify that seat belts be worn at all times when a vehicle is being driven. Safety-Seats, seat belts and supplemental restraint system 1-13
