General notes 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.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This isnormal and not a sign that there is a malfunc-
tion.

Operating the climate control systemsClimate control
Using COMAND, you can:
R switch the perfume atomizer on and off
R regulate the perfume intensity
See the separate operating instructions.
The following conditions can affect your per-
ception of the perfume intensity:
R operating mode of the automatic climate
control
R interior temperature
R time of year/day
R air humidity
R physiological condition of occupants, e.g.
fatigue or hunger
The perfume atomizer can only be operated
when the automatic climate control 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 froma 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.
X To insert the perfume vial: open the glove
box (Y page 373).
X Slide the perfume vial into the holder as far
as it will go.
X To remove the perfume vial: pull out the
perfume vial.
X To refill the perfume vial: unscrew the lid
of the empty perfume vial to refill it your-
self.
X Refill the vial with a maximum of 15 ml of
the desired liquid perfume.
X Screw 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. Operating the climate control systems
