Automatic climate control
Air conditioning
The air conditioning is operational while
the engine is running and cools the inte-
rior air to the temperature set by the op-
erator.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the auto-
matic climate control system. The air in
the vehicle will then no longer be cooled
or dehumidified.
Press button AC OFF ( page 202).
The indicator lamp on the
button AC OFF comes on.
Activating
Moist air can fog up the windows. You
can dehumidify the air with the air con-
ditioning.
Press AC OFF again ( page 202).
The indicator lamp on the
button AC OFF goes out.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Residual heat and ventilation
With the engine switched off, it is possi-
ble to continue to heat or ventilate the
interior for up to 30 minutes. This fea-
ture makes use of the residual heat pro-
duced by the engine.
Activating
Turn the SmartKey in the starter
switch to position 1 or 0 or remove it
from the starter switch.
Press button T ( page 202).
The indicator lamp on button T
comes on.
Deactivating
Press button T ( page 202).
The indicator lamp on button T
goes out.
The residual heat is automatically turned
off:
when the ignition is switched on
after about 30 minutes
if the battery voltage drops
i
Condensation may drip out from
underneath the vehicle. This is nor-
mal and not an indication of a mal-
function.
i
If the AC OFF button on the automat-
ic climate control panel starts to flash,
this indicates that the air condition-
ing is losing refrigerant. The compres-
sor has turned itself off. The air
conditioning cannot be turned on
again.
Have the air conditioning checked at
the nearest authorized Maybach
Studio.
i
How long the system will provide
heating depends on the coolant tem-
perature and the temperature set by
the operator. The blower will run at
speed setting 1 regardless of the air
distribution control setting.
