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.
Activating: Press button,
(
page 453) up or down.
The indicator lamp on the button
comes on.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.
iIf 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.
iMaximum 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 247) is activated, or
press button;.
iThe 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 247) or the outside temperature is be-
low 41°F (5°C), the air recirculation mode will
not switch on automatically.

Pull out oil dipstick1.
Wipe oil dipstick1 clean.
Fully insert oil dipstick1 into the dip-
stick guide tube.
Pull out oil dipstick1 again after ap-
proximately 3 seconds to obtain accu-
rate reading.
The oil level is correct when it is between
lower mark3 (min.) and upper mark2
(max.) mark of the oil dipstick.
If necessary, add engine oil.
For adding engine oil (
page 516).
For more information on engine oil, see the
“Technical data” section (
page 684) and
(
page 686).
For more information on messages in the
multifunction display concerning engine
oil, see the “Practical hints” section
(
page 580).Adding engine oil
iThe filling quantity between the upper and
lower marks on the oil dipstick is approximately
2.1 US qt. (2.0 l).
!Only use approved engine oils and oil filters
required for vehicles with Maintenance System
(U.S. vehicles. Canada vehicles, depending on
vehicle production date) or FSS PLUS (Canada
vehicles, depending on vehicle production date).
For a listing of approved engine oils and oil fil-
ters, refer to the Factory Approved Service
Products pamphlet (USA only) in your vehicle
literature portfolio, or contact an authorized
Mercedes-Benz Center.
Using engine oils and oil filters of specification
other than those expressly required for the Main-
tenance System (U.S. vehicles. Canada vehicles,
depending on vehicle production date) or
FSS PLUS (Canada vehicles, depending on vehi-
cle production date), or changing of oil and oil fil-
ter at change intervals longer than those called
for by the Maintenance System (U.S. vehicles.
Canada vehicles, depending on vehicle produc-
tion date) or FSS PLUS (Canada vehicles, de-
pending on vehicle production date) will result in
engine or emission control system damage not
covered by the Mercedes-Benz Limited

690 Technical data
Fuels, coolants, lubricants, etc.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum parts. Failure to use such anticorrosion/
antifreeze coolant will result in a signifi-
cantly shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
MB 325.0 Anticorrosion/Antifreeze agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Center for service.
