Overview of climat ec ontrol systems
General notes Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preven tt he windows from fogging up:R
switch off climate control only briefly R
switch on air-recirculation mode only briefly R
switch on the cooling with air dehumidifica-
tion function R
switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control can only be operated when the
engin eisr unning. Optimum operation is only
achieved with the side windows and roof closed.
i When the weather is warm, ventilate the
vehicle for ab rief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Ac logged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway so bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e .g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.102

Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The indicator lamp on
the l button flashes.
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The on-board voltage is too low because too many electrical consum-
ers are switched on. X
Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window defroster
can be activated again.
The roof is open. X
Close the roof.
When the roof is closed, the rear window defroster can be activated
again.
Switching air-recirculation mode
on/off
General notes If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.
Switching on/off X
Turn the SmartKey to position 2 in the ignition
lock ( Y
page 115).X
To switch on: press the r button.
The indicator lamp in the r button lights
up.
i Air-recirculation mode is automatically acti-
vated at high levels of pollution (dual-zone
automatic climate control only) or at high out-
side temperatures. When air-recirculation
mode is activated automatically, the indicator
lamp in the r button is not lit. Outside air
is added after about 30 minutes. X
To switch off: press the r button.
The indicator lamp in the r button goes
out. i Air-recirculation mode deactivates auto-
matically: R
after approximately five minutes at outside
temperatures below approximately 41 ‡
(5 †) R
after approximately five minutes if cooling
with air dehumidification is deactivated R
after approximately 30 minutes at outside
temperatures above approximately 41 ‡
(5 †) if the "Cooling with air dehumidifica-
tion" function is activated
Switching the residual heat on or off
General notes The residual heat function is only available on
vehicles for Canada.
It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutesafter the engine has
been switched off. The heating time depends on
the set interior temperature.
Activating/deactivating X
Turn the SmartKey to position 0 in the ignition
lock or remove it ( Y
page 115).X
To activate: press the K or V button.
The indicator lamp in the K or V button
lights up.
i The blower will run at al ow speed regardless
of the airflow setting.Operating the climate control systems 111

The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windshiel da nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.

acteristics), you can continue to drive you rv ehi-
cle even if there is at otal loss of pressure in one
or more tires.
MOExtended tires may only be use dinc onjunc-

system or with an active tire pressure monitor
and on wheels specifically tested by Mercedes-
Benz.
Notes on driving with MOExtended tires with a
flat tire ( Y

Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefore recommende dt hat you additionally
equip you rv ehicl ew ith aT IREFIT kit if you mount
