Resetting activated head restraints
If the active head restraint have been trig-
gered in an accident, the head restraints
must be reset. Otherwise, active head re-
straint cannot offer any additional protec-
tion in the event of another rear-end
collision.
You can tell that the head restraints have
been activated when they have been
moved forward and cannot be adjusted.

Take the reset tool out of the
Mercedes-Benz vehicle literature
pouch.

Guide reset tool into center of head re-
straint between head restraint cushion
and rear head restraint cover.

Press reset tool forward in direction of
arrow.

Press reset tool downward until you
hear the head restraint release
mechanism audibly engage.

Pull out reset tool.

Firmly press head restraint cushion
backward towards rear head restraint
cover until it engages.

Repeat this procedure for second head
restraint.
For information on head restraint adjust-
ment, see “Seats” (
page 41).

For your convenience, we recommend that
you have this work carried out by an authorized
Mercedes-Benz Center.
You will find the reset tool for manually operating
the head restraints in the Mercedes-Benz vehicle
literature pouch.Warning!
G
For safety reasons, have the active head re-
straints checked by an authorized
Mercedes-Benz Center after a rear-end colli-
sion.
!
Be careful not to damage upholstery.
Warning!
G
When pushing back the head restraint cush-
ion, take care that your fingers do not be-
come caught between the head restraint
cushion and the cover. Failing to do so may
lead to injury.
