Emergency tensioning retractor (ETR)
The seat belts for the front seats are equipped with
emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the electronic key in
steering lock position 1 or 2.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS
and in rear impacts exceeding a preset severity level.
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.
In cases of other frontal impacts, angled impacts,
roll-overs, certain side impacts, or other accidents
without sufficient frontal or rear impact forces, the
emergency tensioning retractors will not be activated.
The driver and passengers will then be protected by the
fastened seat belts and inertia reel in the usual manner.
For seat belt and emergency tensioning retractor safety
guidelines see page 73.
