Check seat-belt buckle

WARNING: This page is about a different car, the 2016 Porsche Macan and 2015 Porsche Macan. However, it is still accessible from the selected car via links, so may be relevant.

Push the belt latch into the seat-belt buckle until it engages with an audible click. Check whether the lock mechanism has engaged by pulling strongly on the belt strap.

If the belt latch fails to lock in the seat-belt buckle even just once in at least 5 test procedures, the entire seat belt and seat-belt buckle must be replaced.
