320 Operation
Vehicle care
Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently
discolored. By lining the seats with a
proper intermediate cover,
contact-discoloration will be prevented.Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject to
a natural aging process. Leather
upholstery may also react to certain
ambient influences such as high humidity
or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.
Exercise particular care when cleaning
perforated leather as its underside should
not become wet.
MB Tex upholstery
Use Mercedes-Benz approved Interior
Care onto a soft, lint-free cloth and
apply with light pressure for cleaning
the upholstery.Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of the active head restraints. Contact an
authorized Mercedes-Benz Center for
availability.
!Wipe with light pressure to avoid damage to
the upholstery.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as these
may be abrasive.

Resetting activated head restraints
Resetting activated head restraints
If the active head restraints have been trig-
gered in a rear-end collision, the active
head restraints must be reset. Otherwise,
the active head restraint cannot offer any
additional protection in the event of anoth-
er rear-end collision.
You can tell that the head restraints have
been triggered when they have been
moved forward and cannot be adjusted.

tween the rear head restraint cover2

rection of the arrow.
Press the reset tool3 downward until
you hear the head restraint release
mechanism audibly engage.
Pull out reset tool 3.
Firmly press the head restraint
cushion1 back toward the rear head

head restraint for the second front
seat.
For information on active head restraints,
see “Active head restraint” (
page 73).
For information on head restraint adjust-
ment, see “Seats” (
page 34).
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 active head restraints in the Mercedes-Benz
vehicle literature pouch.

straints 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
