Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with
emergency tensioning devices and seat
belt force limiters.
The ETD is designed to activate in the
following cases:
ț in frontal or rear-end impacts exceed-
ing the system deployment threshold
ț if the restraint systems are operational
and functioning correctly, see
1 indicator lamp (
୴ page 64)
ț in certain vehicle rollovers if the sys-
tem determines an additional degree of
protection
When activated, 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 reduce the force exerted by the
seat belts on occupants during a crash.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
̈ Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
̈ Make sure the infant or child is
properly secured at all times while the
vehicle is in motion.
i
The ETDs will only activate if the seat belts
are fastened (latch plate properly inserted into
buckle).
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
authorized Mercedes-Benz Center.
Warning! G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could
ț injure themselves on parts of the vehicle
ț be seriously or fatally injured through
excessive exposure to extreme heat or
cold
