Seat Belt Retractor: Description and Operation
Dual Locking Mode Retractors
WARNING: After any vehicle collision, the safety belt system at all outboard seating positions (except driver, which has no automatic
locking retractor [ALR] feature) must be checked by a qualified technician to verify that the ALR feature for child safety seats is still
functioning correctly, in addition to other checks for correct safety belt system function. A new belt and retractor assembly must be installed
if the safety belt assembly's ALR feature or any other safety belt function is not operating correctly when checked according to the
procedures. Failure to install a new belt and retractor assembly could increase the risk of injury in collisions.
NOTE: When installing a new dual locking mode retractor, the retractor should be checked to make sure it is not in the automatic locking retractor
(ALR) mode after installation in the stowed position.
All continuous-loop, 3-point retractor systems (except the driver position) are equipped with the dual locking mode system.
The emergency locking retractor (ELR) mode will allow the occupant freedom of movement, locking tight only on hard braking, hard cornering or an
impact of approximately 8 km/h (5 mph). The ELR mode helps to reduce the forward movement of the driver and passengers. The ELR mode is
continuously in operation at all seating positions.
The ALR portion of this system does not allow the occupant freedom of movement. The ALR mode is used when locking a child seat in a seating
position or when a tight belt fit is desired. The ALR mode is disengaged when the webbing is free to move in or out of the retractor. The ALR mode is
automatically engaged when the webbing is fully extracted from the retractor and then allowed to retract. As the webbing is retracted back onto the
spool an audible clicking sound is made indicating that the retractor is in ALR mode. The ALR mode is automatically disengaged when most of the
webbing is retracted back onto the spool.
The automatic locking mode must be used when installing a child safety seat in the front or rear passenger seating positions, where dual locking mode
retractors are provided.
Energy Management Retractor
This vehicle has a safety belt system with an energy management feature at the front seating positions to help further reduce the risk of injury in the
event of a head-on collision.
The energy management retractor feature is designed to pay out webbing in a controlled manner. This feature is designed to help reduce the belt force
acting on an occupant's chest.
