(page 151).
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 conditioning
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.
iIf you keep button
O
pressed, the
side windows and the panorama slid-
ing/pop-up roof will be closed.
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 (charcoal filter activated)
The charcoal filter must be activated
(
page 156) for the air recirculation
mode to be activated automatically.
If you have turned off the air condition-
ing (page 157) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.
iIf you keep button
O
pressed the
side windows and the panorama slid-
ing/pop-up roof will be returned to
their previous position.

The activated charcoal filter should be
switched off when windows fog up on the

needs to be quickly heated or cooled
down.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-

defroster is automatically deactivated af-

ation depending on the outside
temperature.

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 buttonAC

The indicator lamp on the
buttonAC

The air conditioning system uses the refrig-
erant R134a. This refrigerant is free of
CFCs which are harmful to the ozone layer.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts blinking, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If the air conditioning cannot be turned
on again, this indicates that the air con-
ditioning system is losing refrigerant.
The compressor has turned itself off.
Have the air conditioning system
checked at the nearest authorized
Mercedes-Benz Center.

325 Technical data
Consumer information
Consumer information
The following text is published as required
of all manufacturers of passenger cars un-
der Title 49, Code of U.S. Federal Regula-
tions, Part 575 pursuant to the “National
Traffic and Motor Vehicle Safety Act of
1966”.Uniform tire quality grading
Quality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.Tread wear
The tread wear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
a nd one-ha lf (1½ ) tim es as wel l on the gov-
ernment course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.Traction
The traction grades, from highest to lowest
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Tread wear

The traction grade assigned to this tire is
based on straightahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
