Automatic Belt Retractor (Locking Function), Checking
WARNING: This page is about a different car, the 2021 Audi e-tron Quattro and 2019 Audi e-tron Quattro. 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 difficulties are experienced when pulling out or retracting belt, first check whether position of the belt retractor has been altered.
- The second locking function is initiated by change in vehicle velocity (vehicle-dependent locking function).
Test 2
- For safety reasons, the road test should be carried out on roads without traffic so that other motorists/pedestrians, etc. are not endangered.
-- Fasten the seat belt.
-- Accelerate the vehicle to 20 km/h and then perform a hard braking maneuver using 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.
