Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with
emergency tensioning devices (ETDs) and
seat belt force limiters.
The ETD is designed to activate in the fol-
lowing cases:
ț
in frontal or rear-end impacts exceed-
ing a preset severity level.
ț
if the restraint systems are operational
and functioning correctly, see
“
1 indicator lamp” (
୴
page 62).
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.
i
The ETDs for the seats will only activate
if the respective seat belt is fastened
(latch plate properly inserted into buck-
le).
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When scrapping the emergency tensioning
device, our safety instructions must be fol-
lowed. These are available at your autho-
rized Mercedes-Benz Center.
!
Do not place objects heavier than
20 lbs (9 kg) on the passenger seat.
This could cause the front air bag or
head-thorax air bag on the passenger
side and, with the seat belt fastened to
secure the object, the ETD to deploy in
a crash which exceeds the system’s
deployment threshold.
