Checking inertia reel (locking effect)

The inertia reel has two locking functions.

• The first locking function is triggered by pulling belt quickly out of inertia reel (accelerated belt unwinding).

Checking

• Pull belt firmly out of inertia reel.

• If there is no locking effect, replace seat belt complete with buckle.
• In the event of problems with belt unwinding or retraction, start by checking whether position of inertia reel has changed.
• The second locking function is triggered by altering vehicle motion (vehicle-dependent locking function).

Checking

• Fasten seat belt.
• Accelerate vehicle to 20 km/h and then press foot brake to implement emergency braking.

• If braking does not cause belt to be locked by locking mechanism, replace seat belt complete with buckle.
