Seat Belt Latch Function Test

Checking seat belt latch:

- Insert belt tongue into belt buckle until it clicks into place. Check whether the locking mechanism is properly engaged by giving the belt webbing a firm jerk.

• Replace the seat belt complete with seat belt latch if belt tongue fails even only once to engage properly in seat belt latch during at least 5 tests.

Check release mechanism:

- Press the seat belt latch to release the seat belt.

- With the seat belt relaxed, the lock tongue must spring out of seat belt latch without assistance.

• Perform the test at least 5 times. Replace the seat belt completely together with the seat belt latch if the lock tongue fails to spring out even once.


Under no circumstances may grease be used to eliminate noise or stiffness at belt buckle buttons.
