If the LATCH system was being used during a more severe crash, you may need new LATCH system parts. If you see ever a label on the driver's or right front passenger's safety belt that says to replace the belt, be sure to do so. Then the new belt will be there to help protect you in a collision. You would see this label on the belt near the door opening. If belts are cut or damaged, replace them. Collision damage also may mean you will need to have LATCH system, safety belt or seat parts repaired or replaced. New parts and repairs may be necessary even if the belt or LATCH system wasn't being used at the time of the collision. If an air bag inflates, you'll need to replace air bag system parts. See the part on the air bag system earlier in this section. 1-85
