OFF” function is used to permanent-
ly switch off the cooling function of the au-
tomatic climate control system.

tral climate control menu.

Selecting “AC
OFF”: Slide qmr or
rotateymz.

Confirming selection: Press n.
A checkmark appears when the cooling
is switched off.
“AC
OFF” appears in the central menu of
the climate control settings.Selecting “Mono” mode
“Mono” is used to adjust the climate zones
for the entire vehicle at the same time.
When the “Mono” function is switched on
and you change the climate on the driver’s
side, these changes will be carried out in
the same manner for all climate zones.

Select climate control settings
Cen-
tral climate control menu.

Selecting “Mono”: Slide qmr or
rotateymz.

Confirming selection: Press n.
A checkmark appears when the func-
tion has been selected.

Exiting menu: Press back button L
in the center console (

slideomp.
i
Condensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.Warning!
G
If you turn 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.
!
If the air conditioning cannot be turned on
again, this indicates that the air conditioning is
losing refrigerant. The compressor has turned it-
self off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.

The indicator lamp on the button
comes on.
The air conditioning switches to the follow-
ing functions automatically:


most efficient blower speed and heat-
ing power, depending on outside tem-
perature


air flows onto the windshield and the
front side windows


the air conditioning compressor
switches on at outside temperatures
above approximately 41°F (5°C) for
air-drying


the air recirculation mode is switched

You can adjust the air volume and the tem-
perature when the front defroster is
switched on. The air flow will remain on the
windshield and door windows.

Press buttonQ up or down to in-
crease or decrease air volume to the
desired level.

Maximum cooling MAXCOOL (USA only)
If U is selected on both the left and
right side and there is a high demand for
cooling, the display “MAXCOOL” appears
in the COMAND display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof are closed).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving in a
tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
!
The rear window defroster uses a large
amount of power. To keep battery drain to a min-
imum, switch off the defroster as soon as the
rear window is clear.
i
The defroster is automatically deactivated
after some time of operation depending on the
outside temperature.
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.i
If the rear window defroster switches off too
soon and the indicator lamp goes out, this indi-
cates that too many electrical consumers are op-
erating simultaneously and the load on the
battery is reducing available voltage. The system
responds automatically by deactivating the rear
window defroster.
i
Maximum cooling MAXCOOL is only avail-
able when the engine is running.Warning!
G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning (
page 272) is activated, or
press button;.

497 Controls in detail

Activating: Press button,
(page 491) up or down.
The indicator lamp on the button
comes on.

Deactivating: Press button,
(page 491) up or down.
The indicator lamp on the button goes

nience closing or opening feature
i
The air recirculation mode is activated auto-
matically at high outside temperatures.
The indicator lamp on button, is not lit when
the air recirculation mode is automatically acti-
vated.
A quantity of outside air is added when the cool-
ing demand is not at maximum.
If the air conditioning has been turned off
(
page 272) or the outside temperature is be-
low 41°F (5°C), the air recirculation mode will
not switch on automatically.
i
The manually selected air recirculation
mode is deactivated automatically:


after 5 minutes if the outside temperature is
below approximately 41°F (5°C)


after 5 minutes if the air conditioning is
turned off


after 30 minutes if the outside temperature
is above approximately 41°F (5°C)
Warning!
G
Never operate the side windows and the
tilt/sliding sunroof if there is the possibility
of anyone being harmed by the closing pro-
cedure.
When using the air recirculation mode with
convenience closing feature, should the up-
ward movement of a window be blocked by
some obstruction including but not limited
to arms, hands, fingers, etc., the automatic
reversal feature will not operate.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by pressing
the respective window switch. The closing of
the tilt/sliding sunroof can be immediately
halted by moving the tilt/sliding sunroof
switch in the overhead control panel in any
direction.

736 Technical dataFuels, coolants, lubricants, etc.Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System. For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet (USA
only), or contact an authorized
Mercedes-Benz Center.
Engine oil additivesAir conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or chang-
ing of oil and oil filter at change intervals longer
than those called for by the Maintenance System
will result in engine or emission control system
damage not covered by the Mercedes-Benz Lim-
ited Warranty.
Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.
!
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from blending
oil additives are not covered by the
Mercedes-Benz Limited Warranty.
!
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!
G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere.
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement inter-
val.
