200 Controls in detailDual-zone automatic climate controlThe climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent 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 AC
OFF
mode is activated or
AC mode is deactivated (
page 206).
Warning!
G
When operating the 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 frost-
bite to unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary
change the air flow using the air distribution
controls (
page 198) to direct the air away
from the footwell air vents.
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 pollu-
tion) may require replacement of the fil-
ter 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.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.

Setting the temperature
Use temperature controls1 and6
(page 198) or (
page 199) to separate-
ly adjust the air temperature on each side
of the passenger compartment. You
should raise or lower the temperature set-
ting in small increments, preferably start-
ing at 72°F (22°C).
Increasing

Turn the temperature control1 or6
(page 198) or (
page 199) slightly
to the right.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
Decreasing

Adjusting air distribution
Use air distribution control4
(page 198) or (
page 199) to adjust the
air distribution.
iWhen the air conditioning is switched
off, the outside air supply and circula-
tion are also switched off. Only choose
this setting for a short time. Otherwise
the windows could fog up.

Dual-zone automatic climate control
Deactivating
Press buttonO (
page 198) or
(
page 199).
The indicator lamp on the button goes
out.The air recirculation mode is deactivated
automatically:


after five minutes if the outside temper-

(5°C)


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside temper-
ature is above approximately 41°F
(5°C)
At outside temperatures above 79°F
(26°C), the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
iThe air recirculation mode is activated
automatically at high outside tempera-
tures.
If you have turned off the air condition-
ing (
page 206) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.
iIf you keep buttonO pressed, the
side windows and tilt/sliding sunroof*
will return to their previous position.

206 Controls in detailDual-zone automatic climate controlAir conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!
G
If you turn off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog
up more quickly. Window fogging may
impair visibility and endanger you and
others.

207 Controls in detail
Dual-zone automatic climate control
Residual heat and ventilation*
(available on climate control panel de-sign A only)
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
Activating
Turn the SmartKey in the starter switch
to position0or1, or remove it from
the starter switch.

Press buttonT (
page 198).
The indicator lamp on button comes
on.Deactivating

Press buttonT (
page 198).
The indicator lamp on button goes out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops
!If the air conditioning cannot be turned
on again, this indicates that the air con-
ditioning is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting 1 regardless of the air distribu-
tion control setting.
