these items are available as
factory-installed equipment (whether

The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.

coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.

440 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.
You can tell that the head restraints have
been triggered 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 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 87).
For information on head restraint adjust-
ment, see “Seats” (
page 43).

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.Warning!
G
For safety reasons, have the active head re-
straints checked by an authorized
Mercedes-Benz Center after a rear-end colli-
sion.
Warning!

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.
