Problems with the "Cooling with air dehumidification" function
ProblemPossible causes/consequences andMSolutions
The indicator lamp in
theÁ button
flashes three times or
remains off. Cooling
with air dehumidifica-
tion can also no longer
be switched on using
COMAND (see the sep-
arate operating instruc-
tions).Cooling with air dehumidification has been deactivated due to a
malfunction.

Setting climate control to automatic
General notes
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.

tion lock (

tion which has not been changed manually,
however, continues to be controlled automat-
ically. When the manually set function

Rear window defroster
General notes
The rear window defroster has a high current draw. You should therefore switch it off as
soon as the rear window is clear. Otherwise,
the rear window defroster switches off auto-
matically after several minutes.
If the battery voltage is too low, the rear win-
dow defroster may switch off.

Problems with the rear window defroster
ProblemPossible causes/consequences andMSolutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated.The battery has not been sufficiently charged.
XSwitch 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.
Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow
of fresh air manually if unpleasant odors are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
Activating or deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 151).
XTo activate: press thegrocker switch
up or down.
The indicator lamp in the grocker
switch lights up.
Air-recirculation mode is automatically acti-
vated at high levels of pollution or at high out-
side temperatures. The indicator lamp in the
g rocker switch is not lit when automatic
air-recirculation mode is activated. Outside
air is added after about 30 minutes.
XTo deactivate: press thegrocker
switch up or down.
The indicator lamp in the grocker
switch goes out. Air-recirculation mode deactivates automati-
cally:
Rafter approximately five minutes at outside
temperatures below approximately 41 ‡

Rafter approximately five minutes if cooling
with air dehumidification is deactivated
Rafter approximately 30 minutes at outside
temperatures above approximately 41 ‡

tion" function is activated
Switching the residual heat on or off
General notes
Once the engine is switched off, it is possible
to make use of the residual heat of the engine
to continue heating or ventilating the front
compartment of the vehicle for approximately
30 minutes.
The heating or ventilation time depends on
the temperature that has been set.

XTurn the SmartKey to position 0in the igni-
tion lock or remove it (

GWARNING
If children open the perfume vial, they could
drink the perfume or it could come into con-
tact with their eyes. There is a risk of injury. Do not leave children unsupervised in the vehicle.
If the perfume liquid has been drunk, consult
a doctor. If perfume comes into contact with
your eyes or skin, rinse the eyes with clean
water. If you continue to experience difficul-
ties, consult a doctor.
HEnvironmental note
Full perfume vials must not
be disposed of with house-
hold rubbish. They must be
collected separately and
recycled to protect the envi-
ronment.
Dispose of full perfume vials
in an environmentally
responsible manner and
take them to a special wastecollection point.

The perfume atomizer helps to improve driv-
ing comfort.
Using COMAND, you can:
Rswitch the perfume atomizer on or off
Rregulate the perfume intensity (see the sep- arate operating instructions)
The following conditions can affect your per-
ception of the perfume intensity:
Roperating mode of the climate control sys-
tem
Rinterior temperature
Rtime of year or day
Rair humidity
Rphysiological condition of occupants, e.g.
fatigue or hunger
The perfume atomizer can only be operated
when the climate control system is switched
on and is only active when the glove box is
closed.
The perfume atomizer is provided with a pre-
filled perfume vial. You can also choose from
a variety of filled perfume vials and an empty
vial which you can fill yourself.
If you refill an empty perfume vial, observe the
separate information sheet attached to the
vial.
!If you do not use genuine Mercedes-Benz
interior perfumes, observe the manufactur-
ers' safety notices on the perfume packag-
ing.

Do not refill the pre-filled perfume vial when it
is empty. Dispose of the used vial after use.
XTo insert the perfume vial:open the glove
box (
Ypage 301).
XSlide the perfume vial into the holder as far as it will go.
XTo remove the perfume vial: pull out the
perfume vial.
XTo refill the perfume vial: unscrew the lid
of the empty perfume vial to refill it your-
self.
XRefill the vial with a maximum of 15 ml of
the desired liquid perfume.
XScrew the lid back on to the vial.
!Only refill the vial when you are outside
the vehicle. Otherwise, liquid perfume
could drip into the interior and contaminate
it.
Always refill the empty refillable vial with the
same perfume. Otherwise, you might not ach-
ieve optimum results from the perfume atom-
izer.

Ionization
You can use the "Ionization" function to purify
the air in the vehicle interior and attain an
improved interior climate.
The ionization of the interior air is odorless
and cannot be perceived directly in the vehi-
cle interior.
You can switch ionization on or off using
COMAND (see the separate operating
instructions).
Ionization can only be switched on if the front
climate control system is activated. The side
air vent on the driver's side must be open.
Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves.
Rnever cover the air vents or air intake grilles in the vehicle interior.
