Checking latching mechanism:

Push belt tongue into latch until it engages with an audible "click." Check whether latching mechanism is properly engaged by giving belt firm pull.
If belt tongue fails even only once to engage properly in belt latch during at least 5 tests, seat belt complete with belt latch must be replaced.

Checking releasing mechanism:

Release seat belt by pressing button on belt latch with finger pressure.
When belt is slack, tongue must spring out of belt latch on its own.
Carry out test at least 5 times. If belt tongue fails even only once to spring out of latch, seat belt complete with belt latch must be replaced.
WARNING: Never use lubricant to eliminate noise or stiffness at belt lock buttons.
