For more information, see “Practical hints”
(Y page 259).
Emergency Tensioning Device (ETD),
seat belt force limiter The seat belts are equipped with ETDs and
seat belt force limiters. The ETDs are designed to activate in the
following cases:
R
in frontal or rear-end impacts exceeding
the system’s preset deployment threshold
R if
the restraint systems are operational and
functioning correctly, see “SRS indicator
lamp” (Y page 32)
R in certain vehicle rollovers if the system
determines an additional degree of
protection
The ETDs will only activate if the seat belts are
fastened (latch plate properly inserted into
buckle).
In an impact, the ETDs 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.
i The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back
toward the seat backrest. G
Warning!
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Benz Center. Correct driver seat adjustment

Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.
Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident. Seat adjustment
The seats can be adjusted either manually or
