Emergency tensioning retractor (ETR)
In cases of other frontal impacts, angled impacts, roll-
overs, certain side impacts, or other accidents without
sufficient frontal or rear 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.
The seat belts for the front and outer rear 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.
For seat belt and emergency tensioning retractor safety
guidelines, see page 75.
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.
Note:
The front passenger ETR activates only if the front
passenger seat is occupied.
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy and the ETR to activate in a crash exceeding the
appropriate threshold.
