easy-entry/exit feature activated, the

head restraints
For information on head restraint
adjustment, see “Seats” (
page 35). If the current seat position falls into a
factory-set position range and the
system recognizes the current seat
position to be rearward enough for
easy entry and exit, the driver’s seat
will not move to the rear when the
easy-entry/exit feature is activated.
iFor safety reasons, the driver’s seat will
not return to its last set position with
the easy-entry/exit feature activated if
the system recognizes the last set posi-
tion as an extreme forward position.
Instead, the driver’s seat will remain at
or move to a factory-set maximum
forward position. To again fully return
the driver’s seat to your last set posi-
tion or to memory position, adjust the
seat to the desired position or press
and hold the respective memory
position switch* (
page 107).
iAdjust the head restraint in such a way
that it is as close to the head as
possible.Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.

299 Operation
Vehicle care
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved
Leather Care.
Cup holders
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution. Wipe with a cloth moist-
ened in lukewarm solution. Do not use
scouring agents.
Hard plastic trim items
Pour Mercedes-Benz approved Interior
Care onto soft lint-free cloth and apply
with light pressure.Headliner and rear window shelf

Seat belts
The webbing must not be treated with
chemical cleaning agents. Only use clear,
lukewarm water and soap. Do not dry the
webbing at temperatures above 176°F
(80°C) or in direct sunlight.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 dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Leather upholstery
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.
Warning!
G
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
