Resetting the maintenance service
indicator
In the event that the maintenance service
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Center, you can
have the maintenance service indicator re-
set. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the main-
tenance service indicator in the mainte-
nance-relevant information for your
vehicle. Such information is available from
any authorized Mercedes-Benz Center or
directly from Mercedes-Benz.iIf the battery is disconnected, the days of
disconnection will not be included in the count
shown by the maintenance service indicator.
To arrive at the true maintenance service dead-
line, you will need to subtract these days from
the days shown in the maintenance service indi-
cator message or maintenance service indicator
display.iIf the maintenance service indicator was in-
advertently reset, have an authorized
Mercedes-Benz Center correct it.
Only reset if the proper maintenance service has
been performed. Resetting the system without
performing the proper service as called for by
the maintenance service indicator will result in
engine damage and/or other vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.

Resetting activated head restraints
Resetting activated head restraints
If the active head restraints (front seats)
have been triggered in an accident, the ac-
tive head restraints must be reset. Other-
wise, the active head restraints cannot
offer any additional protection in the event
of another rear-end collision.
You can tell that the head restraints have
been triggered when they have been
moved forward and cannot be adjusted.
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 “Active head restraints” (
page 55).
For information on head restraint adjust-
ment, see “Head restraints” (
page 353).
iFor 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
restraints checked by an authorized
Mercedes-Benz Center after a rear-end
collision.
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.
!Be careful not to damage upholstery.
