Automatic Locking Retractor (ALM) Available only in certain markets
ALR is a locking system for child seats which consists of a small, integrated 'transmission' in the inertia reel. When the entire length of the belt has been extracted, ALR provides a constant locking function. A ticking sound indicates that the function is active.
In order to disconnect the function, the belt should be fed in sufficiently, whereupon the belt will release.
