Seats Active Head Restraints This reduces the distance between the restraint and the occupant's head. It also helps protect the occupants against the likelihood of whiplash and injuries to the neck and upper spine. After a collision, the activated restraint should return to its normal position. If the restraints do not return to their normal position, or in the event of a severe collision, have the vehicle inspected by an Acura dealer. For a head restraint system to work properly: ● Do not hang any items on the head restraints, or from the restraint legs. Do not place any object between an occupant and the seat-back. Install each restraint in its proper location. Only use genuine Acura replacement head restraints. ● ● ● The driver's and front passenger's seats have active head restraints. If the vehicle is struck severely from the rear, the occupant properly secured with the seat belt will be pushed against the seat-back and the head restraint will automatically move forward. 152
