Air 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.

comes on.
The cooling function and heater boost-
er system (Diesel engine) (
page 203)
are switched off.

Climate control panel design B

Press button2 (
page 195) again.
The indicator lamp on the button

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.


202 Controls in detailDual-zone automatic climate control
Residual heat and ventilation* (avail-
able on climate control panel design 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 194).
The indicator lamp on button comes
on.Deactivating

Press buttonT (
page 194).
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.

Dual-zone automatic climate control
Heater booster system (Diesel engine)
Your vehicle is equipped with a heater
booster system. A PTC heating element
(page 475) ensures that the vehicle inte-
rior is warmed up as quickly as possible
when the engine has not reached its nor-
mal operating temperature yet.
The heater booster system switches on au-
tomatically if required.iIf the cooling function for the air condi-
tioning is switched off with the
±button, the heater booster sys-
tem is deactivated too (Climate control
panel design A only).

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.
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.
