Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning 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 in certain vehicle rollovers
ț if the restraint systems are operational
and functioning correctly, see
1 indicator lamp (
୴ page 66)
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.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Active head restraints
The active head restraints are intended to
offer the driver and front passenger in-
creased protection from head and neck in-
jury. In the event of a rear-end collision,
the head restraints on the driver’s and
front passenger’s seats are designed to
move forward in the direction of travel,
providing the head with increased support
earlier on in the collision sequence. The ac-
tive head restraints move forward whether
the seat is occupied or not.
i
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 outer 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.
Warning!
G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model. Us-
ing other seat or head restraint covers may
interfere with or prevent the activation of
the active head restraints. Contact your au-
thorized Mercedes-Benz Center for availabil-
ity.
