191 Controls in detail
Automatic climate control
Deactivating the automatic climate control systemDeactivating
It is possible to completely deactivate the
automatic climate control system.

Press button M (
page 184).
The indicator lamp on button M
comes on.Reactivating
There are several ways to reactivate the
automatic climate control system:

Press any button on the automatic cli-
mate control panel (
page 184).
The indicator lamp on button M
switches off.
or

Turn one of the control knobs on the
automatic climate control.
The indicator lamp on button M
switches off.
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.
iUnder certain circumstances, e.g.
when the fuel system is too hot and
needs to be cooled, the cooling switch-
es on again automatically. The red lamp
on the ± button the automatic cli-
mate control panel flashes.
After cooling the fuel system sufficient-
ly, the air conditioning switches off
again and the red lamp stops flashing.

192 Controls in detailAutomatic 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 automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.

Press ± button (
page 184).
The indicator lamp on the ±
button comes on.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press ± button again (
page 184).
The indicator lamp on the ± button
goes out.
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.
iUnder certain circumstances, e.g.
when the fuel system is too hot and
needs to be cooled, the cooling switch-
es on again automatically. The red lamp
on the ± button the automatic cli-
mate control panel flashes.
After cooling the fuel system sufficient-
ly, the air conditioning switches off
again and the red lamp stops flashing.
!If you press the ± button on the au-
tomatic climate control panel and it
starts to flash, this indicates that the
air conditioning is losing refrigerant.
The compressor has turned off. The air
conditioning cannot be turned on
again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.

Tire and loading terminology
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as
factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
Bead
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the
rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle
has been sitting for at least three hours or
driven no more than one mile (1.6 km).
Curb weight
The weight of a motor vehicle with stan-
dard equipment including the maximum
capacity of fuel, oil, and coolant, and, if so
equipped, air conditioning and additional
optional equipment, but without passen-
gers and cargo.
