Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts for the front and rear seats
are equipped with emergency tensioning
devices and seat belt force limiters.
The ETD is designed to activate in the
following cases:
앫
in frontal or rear-end impacts exceed-
ing the system deployment threshold
앫
in certain vehicle rollovers
앫
if the restraint systems are operational
and functioning correctly,
see
=
indicator lamp (

page 575)
In an impact, emergency tensioning
devices remove slack from the seat belts in
such a way that the seat belts fit more
snugly against the body. Seat belt force
limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for the
front seats reduces the retracting force of
the seat belts when they are in normal use.
i
The ETDs for the front seats will only acti-
vate if the front seat belt is fastened (latch plate
properly inserted into buckle).
The ETDs for the rear seats will activate with or
without the respective seat belt fastened.
Warning!
G
A pyrotechnic Emergency Tensioning Device
(ETD) that was activated must be replaced.
When disposing of the pyrotechnic emer-
gency tensioning device, our safety instruc-
tions must be followed. These are available
at your authorized Mercedes-Benz Center.
