Safety and Security
Occupant safety
If the active head restraints have been trig-
gered in an accident, the active head re-
straints must be reset. Otherwise, the
active head restraints cannot offer any ad-
ditional protection in the event of another
rear-end collision.
For information on resetting the activated
active head restraints, see "Resetting acti-
vated head restraints" ( page 675).
You cannot remove the active head re-
straint on the driver's and front passen-
ger's seats.
For removal contact an authorized
Mercedes-Benz Center.
Warning!
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 an authorized Mercedes-Benz Cen-
ter for availability.

Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust 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 intend-
ed to help reduce injuries during an acci-
dent.

ment, see "Head restraints" ( page 353).
