Triggering of the seat-belt pretensioners depends on the severity of the accident.
The seat-belt pretensioners are triggered:
In the event of front and rear impact
In the event of side impact
If the vehicle turns over
The seat-belt pretensioner system can be triggered only once; the system must then be replaced.
Work may be carried out on the seat-belt pretensioner system only by qualified specialist workshop employees. We recommend that you get a Porsche partner to do this work as they have trained workshop personnel and the necessary parts and tools.
Smoke is released when the seat-belt pretensioners are triggered. This does not indicate a fire in the vehicle.
Fasten seat belt
Assume a comfortable sitting position.
Adjust the seat backrest so that the belt rests fully on your upper body and runs across the middle of your shoulder.
Grasp the belt tongue and pull the belt in a slow, continuous motion across your chest and lap.
The belt may be blocked if the vehicle is standing at an angle or the belt is pulled out using a jerking movement.
It might not be possible to pull out the belt while accelerating or slowing down, when cornering or when driving uphill..
Insert the belt tongue into the appropriate buckle on the inboard side of the seat until it locks securely with an audible click.
Make sure that belts are not trapped or twisted and that they are not rubbing on sharp edges.
The horizontal section of the belt should always fit snugly across the pelvis. Therefore, after fastening the belt, always pull the diagonal part of the belt upward.
Pregnant women should position the belt as low as possible across the pelvis, and ensure that it is not pressing against the abdomen.
Pull on the diagonal section of the belt now and again during the journey to ensure that the horizontal section remains tight.
