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.

ment, see “Seats” (

sion.

ion, take care that your fingers do not be-
come caught between the head restraint
