71 Safety and Security
Occupant safety
Active head restraint
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 active 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.
For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (
page 391).You cannot remove the active head re-
straints on the driver’s and passenger’s
seats.
For removal of the active head restraints
we recommend that you contact an autho-
rized Mercedes-Benz Center.
!
Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side and, with the seat belt fastened to
secure the object, the ETD to deploy in
a crash which exceeds the system’s de-
ployment threshold.
Warning!G
Do not attach any objects (e.g. hangers) to
the head restraint posts. Otherwise, the ac-
tive head restraints may not be able to func-
tion properly or offer the intended degree of
protection in the event of an accident.
Warning!G
Only use seat- or head restraint covers
which have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat- or head restraint covers
may interfere with or prevent the activation
of the active head restraints. Contact your
authorized Mercedes-Benz Center for avail-
ability.
