Functional Test - Safety Belt Retractor, Road Test Inspection, Inflatable Safety Belt

Component Test

WARNING: After a crash, the following safety belt components and attaching hardware must be inspected and tested to verify correct function:
- Retractors
- Buckles
- Child safety seat tether bracket assemblies
- ALR (Automatic Locking Retractor) feature for child safety seats (passenger seating positions only)
- BTS (Belt Tension Sensor) (if equipped)
- Front safety belt buckle support assemblies (slide bar) (if equipped)
- Safety belt shoulder belt height adjusters (if equipped)

Components that do not operate correctly or pass all Functional Tests in the Component Tests must be replaced with new components.

Safety belt assembly attaching areas must be inspected. Damaged or distorted attaching areas must be restored to their original structural integrity and a new safety belt assembly with new attaching hardware must be installed.

After deployment of the front safety belt pretensioners, a new safety belt system (including retractors, buckles and height adjusters) must be installed.

Failure to follow this instruction may result in incorrect operation of the safety belt system and increases the risk of serious personal injury or death in a crash.

WARNING: The driver and passenger must be prepared to brace themselves in the event the safety belt retractor does not lock. Failure to follow this instruction may result in serious personal injury.

NOTE: Make sure there is no excessive slack in the safety belt webbing across the torso during testing.

NOTE: Do not jerk on the safety belt webbing when carrying out this test.

1. Move the seat in front of the seating position being tested as far forward as is safely possible.
