(page 148).
The indicator lamp on the button goes
out.The air recirculation mode is deactivated
automatically


after five minutes if the outside temper-
ature is below approximately 41°F
(5 °C)


after five minutes if the air conditioner
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.
Warning!

When the outside temperature is below
41°F (5°C), only switch to air recirculation
mode for short periods to prevent window
fogging.
iIf you keep button
,
pressed, the
side windows will close.
The air recirculation mode is activated
automatically


at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel
If you have turned off the air condition-
er (page 155) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.
iIf you keep button

automatic climate control system:
Press any button on the automatic cli-
mate control panel (
page 148).
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.
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 automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.
Press button AC
OFF
(page 148).
The indicator lamp on the
buttonAC
OFF
lights up.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press AC
OFF
again (
page 148).
The indicator lamp on the
buttonAC
OFF
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.
!If the AC
OFF
button on the automatic
climate control panel starts to blink,
this indicates that the air conditioning
is losing refrigerant. The compressor
has turned itself off. The air condition-
ing cannot be turned on again.


Have the air conditioner checked at
the nearest authorized
Mercedes-Benz Center.

Engine oils
Engine oils are specifically tested for their
suitability in our engines. Therefore, only
use engine oils recommended by
Mercedes-Benz. Information on recom-
mended brands is available in the Factory
Approved Service Products pamphlet, or at
your authorized Mercedes-Benz Center.
Please follow FSS recommendations for
scheduled oil changes. Failure to do so
could result in engine damage not covered
by the Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil.
They may be harmful to the engine opera-
tion.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
er system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil, otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency.
Therefore, the brake fluid must be re-
placed every two years, preferably in the
spring.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
