Release, Checking
-- Press the seat belt latch with finger pressure to release the seat belt. With the seat belt webbing relaxed, the belt tongue must spring out of the seat belt latch without assistance.
- Perform the test at least five times. Replace the entire seat belt with the seat belt latch if the belt tongue fails to spring out even once.
WARNING:
Under no circumstances may lubricant be used to eliminate noise or stiffness at the seat belt latch buttons.
