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 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 60)
In an impact, emergency tensioning devic-
es remove slack from the belts. 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 wouldn’t 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 boost-
er seats, always follow the child seat
manufacturer's instructions.
!
The ETDs for the front seats will only
activate if the front seat belts are fas-
tened (latch plate properly inserted
into buckle).
The ETDs for the rear seats will activate
with or without the respective seat
belts fastened.
Warning! G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Center.
