Air conditioning

The air conditioning is operational while the

engine is running and cools the interior air to

the temperature set by the operator. In

addition, the air conditioning dehumidifies

the interior air and helps prevent window

fogging.

Warning!

If you switch 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.

Condensation may drip out from

underneath the vehicle. This is normal and

not an indication of a malfunction.

Deactivating

It is possible to deactivate the air

conditioning. The interior air will then no

longer be cooled or dehumidified.

Press button

The indicator lamp in the button goes out.

The cooling function switches off after a

short delay.

Activating

Moist air can fog up the windows. You can

dehumidify the interior air with the air

conditioning.

Press button

again.

The indicator lamp in the button comes on.

The air conditioning uses the refrigerant

R134a. This refrigerant is free of CFCs which

are harmful to the ozone layer.

again, this indicates that the air

conditioning is losing refrigerant. The

compressor has turned off.

Have the air conditioning checked at the

nearest authorized Mercedes-Benz Center.

Automatic mode

When operating the climate control system in

automatic mode, the interior air temperature,

air volume and air distribution are adjusted

automatically.

In automatic mode, cooling with

dehumidification is switched on. This function

can be switched off if necessary.

Warning!

If you switch 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
