2018 Audi A5 Quattro Prestige, 2D ConvertibleSECTION Automatic Belt Retractor (Locking Function), Checking
WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2020 Audi S4, 2020 Audi A4 allroad, 2020 Audi A4 Quattro, 2020 Audi A4, and 2019 Audi S4. 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 

WARNING:

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 (12 mph) 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.
