Automatic Belt Retractor (Locking Function), Checking

WARNING: This page is about a different car, the 2020 Volkswagen Arteon and 2019 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.

The automatic belt retractor has two locking functions.

The first locking function is initiated by the belt being jerked out of the automatic belt retractor (belt extraction acceleration).

Test 1

-- Pull the seat belt webbing out of the automatic belt retractor with a firm jerk.

No locking effect - replace the entire seat belt with seat belt latch.
If malfunctions are experienced when pulling out or retracting belt, first check whether position of the automatic belt retractor has been altered.
The second locking function is initiated by change in vehicle velocity (vehicle-dependent locking function).

Test 2

CAUTION:

Risk of injury to others.

- Perform the check of the automatic belt retractor on roads without traffic.

-- Fasten the seat belt.

-- Accelerate the vehicle to 20 km/h (32 mph) and then perform a hard braking maneuver with the foot brake.

Replace the entire seat belt with the seat belt latch if the seat belt is not locked by locking mechanism during the braking procedure.
