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
kmh (14.9 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) (If Equipped)
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.
