618 Practical hintsResetting activated head restraints (S 600 only)If the luxury active head restraints
(front seats) have been triggered in an ac-
cident, the active head restraints must be
reset. Otherwise, the active head re-
straints cannot offer any additional protec-
tion in the event of another rear-end
collision.

Take reset tool1 out of the
Mercedes-Benz vehicle literature
pouch.

Guide reset tool1 into center of head
restraint between head restraint cush-
ion and rear head restraint cover.

Press reset tool1 forward in direction
of arrow.

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

Pull out reset tool1.

Firmly press head restraint cushion
backward towards the rear of the vehi-
cle until it engages.

Repeat this procedure on the active
head restraints for second head re-
straint.
For information on active head restraints,
see “Luxury active head restraints
(S 600 only)” (
page 59).
For information on head restraint adjust-
ment, see “Head restraints” (
page 324).
i
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.
!
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.
