3-56 Seats and Restraints 2.3. Route, attach, and tighten the top tether according to your child restraint instructions and the following instructions: Replacing LATCH System Parts After a Crash { WARNING A crash can damage the LATCH system in the vehicle. A damaged LATCH system may not properly secure the child restraint, resulting in serious injury or even death in a crash. To help make sure the LATCH system is working properly after a crash, see your dealer to have the system inspected and any necessary replacements made as soon as possible. If the vehicle has the LATCH system and it was being used during a crash, new LATCH system parts may be needed. New parts and repairs may be necessary even if the LATCH system was not being used at the time of the crash. If the position you are using has a fixed headrest and you are using a dual tether, route the tether around the head restraint. If the position you are using has a fixed headrest and you are using a single tether, route the tether over the head restraint. 3. Before placing a child in the child restraint, make sure it is securely held in place. To check, grasp the child restraint at the LATCH path and attempt to move it side‐to‐side and back‐and‐forth. There should be no more than 2.5 cm (1 in) of movement, for proper installation.
