362 OperationMaintenanceCalling up the maintenance service indicator display
You can call up the maintenance service
indicator display at any time to check
when the next maintenance service is due.
Switch on the ignition (
page 36).
Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display appears in
the multifunction display (
page 153).
Press button k or j until the
maintenance service indicator display
with the service symbol 9 and the
service deadline appears in the multi-
function display.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
either your 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 deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator message or maintenance ser-
vice indicator display.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator :.

386 Practical hintsWhat to do if …Vehicle status messages in the multi-function display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 153) displays both cleared and
uncleared messages.
High-priority messages appear in the mul-
tifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 150) or
buttonj, k, ÿ or è on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display us-
ing the reset button (
page 150) or
buttonj, k, ÿ or è on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 162). Remember that
clearing a message will only make the mes-
sage disappear. Clearing a message will
not correct the condition that caused the
message to appear.
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated, ad-
dressed as soon as possible at an autho-
rized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property dam-
age or personal injury.Warning!

No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
Contact the nearest authorized
Mercedes-Benz Center.

430 Practical hintsResetting activated head restraintsIf 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.
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 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 77).
For information on head restraint adjust-
ment, see “Seats” (
page 42).
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.
!Be careful not to damage upholstery.
Warning!

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.
