2008 MERCEDES-BENZ CLS500 reset

358 Practical hints
What 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 139) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 26) or
buttonj, k, è orÿ on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button or buttonj,
k, è orÿ on the multifunction
steering wheel. They are then stored in the
vehicle status message memory
(
page 151). Remember that clearing a
message will only make the message
disappear. Clearing a message will not
correct the condition that caused the mes-
sage to appear.
Warning!G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated,
addressed 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.

401 Practical hints
Resetting activated head restraints
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).
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 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.
