System Operation

Emergency Locking Retractor (ELR)

All retractors have an Emergency Locking Retractor (ELR) mode, which is a vehicle-sensitive feature designed to activate and lock the seatbelt webbing during hard braking, cornering, or an impact of approximately 24 km/h (15 mph). The Emergency Locking Retractor (ELR) feature helps reduce the forward movement of the driver and passengers. For testing, see Functional Test - Seatbelt Retractor, Road Test Inspection.
Refer to: Seatbelt Systems (501-20A Seatbelt Systems, Diagnosis and Testing).

Automatic Locking Retractor (ALR)

The Automatic Locking Retractor (ALR) mode is used when locking a child seat in any passenger seating position. The Automatic Locking Retractor (ALR) mode automatically activates when the seatbelt webbing is fully extracted from the retractor and then allowed to retract. As the seatbelt webbing retracts back onto the spool, an audible clicking sound is made, indicating the seatbelt retractor is in Automatic Locking Retractor (ALR) mode and the seatbelt webbing cannot pull back out of the seatbelt retractor. The Automatic Locking Retractor (ALR) mode disengages when the webbing is allowed to fully retract back into the retractor. For testing, see Functional Test - Seatbelt Retractor, Automatic Locking Retractor (ALR) Mode.
Refer to: Seatbelt Systems (501-20A Seatbelt Systems, Diagnosis and Testing).
