Good visibility
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the
defroster as soon as the rear window is
clear. The defroster is automatically
deactivated after approximately
6 to 17 minutes of operation depending on
the outside temperature.Activating

Press buttonF or1 in the
climate control panel (
page 197) or
automatic climate control panel
(
page 197).
The indicator lamp on the button
comes on.
Deactivating

Press buttonF or1 again.
The indicator lamp on the button goes
out.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before
driving. Visibility could otherwise be
impaired, endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are
operating simultaneously and there is
insufficient voltage in the battery. The
system responds automatically by
deactivating the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster
automatically switches on again.

188 Controls in detailClimate control (CLK 350)The climate control is operational when-
ever the engine is running. You can oper-
ate the climate control system in either the
automatic or manual mode. The system
cools or heats the interior depending on
the selected interior temperature and the
current outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated
(
page 194).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite on unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion control (
page 187) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. 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
“Summer opening feature”
(page 249). The climate control will
then adjust the interior temperature to
the set value much faster.
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.
