Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear seats
are equipped with emergency tensioning
devices and belt force limiters.
The ETD is designed to activate in the
following cases:
ț in frontal or rear-end impacts exceed-
ing a preset severity level
ț in certain vehicle rollovers
ț if the restraint systems are operational
and functioning correctly, see
1 indicator lamp (
୴ page 411)
In an impact, emergency tensioning
devices remove slack from the belts in
such a way that the seat belts fit more
snugly against the body. Belt force limiters
reduce the force exerted by the seat belts
on occupants during a crash.
ț Belts should not be worn twisted. In a
crash, you would not have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.
ț Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
ț Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
ț When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer's instructions.
