al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air
enters the passenger compartment
through the air distribution system.
The air conditioning will not engage (no
cooling) if the modeAC
OFF
is activated or
mode A/C is deactivated (page 192).
iFeature availability is based on prelimi-
nary information at time of printing.

be available as optional equipment on
all models.
Warning
G
When operating the automatic climate
control, the air that enters the passenger
compartment through the air vents in the
footwell can be very hot or very cold
(depending on the set temperature). This
may cause burns or frostbite on unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the foot-
well air vents. If necessary change the air
flow using the air distribution controls to
direct the air away from the footwell air
vents (
page 186).
Warning!
G
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.iSevere conditions (e.g. strong air
pollution) may require replacement of
the filter before its scheduled interval.
A clogged filter will reduce the air
volume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off, see
“Opening (Summer opening feature)”
(page 245).
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing
objects on the air flow-through exhaust
slots below the rear window.

Handle CDs carefully to prevent inter-
ference during playback.


Avoid scratches, fingerprints and dust
on the CDs.


Do not write on CDs or apply any labels
or other material to them.


Clean CDs from time to time with a
commercially available cleaning cloth.
Never wipe the CD in a circular motion;
instead, wipe it in a straight line start-
ing in the center and moving outward.
Do not use solvents, anti-static sprays,
etc. for cleaning.


Replace the CD in its case after use.


Protect CDs from heat and direct sun-
light.
!If you affix stickers to the CDs, they can
become warped due to the heat that
develops in the CD drive or CD chang-
er.
In certain situations, the CDs can then
no longer be ejected and cause dam-
age to the drive. Such damage is not
covered by the Mercedes-Benz Limited
Warranty.!Your CD drive or CD changer has been
designed to play CDs which corre-
spond to the EN 60908 standard. You
can therefore only use CDs with a max-
imum thickness of 1.3 mm.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected and
will damage the drive.
