Checking Function Of Three-Point Seat Belt

WARNING: This page is about a different variant/trim than selected.

The belt strap must be rolled up fully when starting the function test.
Move seat-belt height adjustment to its highest position.
Pull the belt strap out fully as far as it will go.
Roll the belt strap up again slowly. An audible buzzing noise can be heard when you do this.
If the rolling-up process is interrupted, the belt strap cannot be pulled out again (permanent belt blockage).
The permanent belt blockage feature must be disabled at least 100 mm before the belt strap is completely rolled up in order to ensure that the belt strap can be pulled out again.
