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 enter-
ing the vehicle from outside. The air already
inside the vehicle will then be recirculated.
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
XTurn the SmartKey to position 2in the ignition
lock (Ypage 131).
XTo activate: press thegrocker switch up
or down.
The indicator lamp above the grocker
switch lights up.
Air-recirculation mode switches on automati-
cally:
Rat high outside temperatures
Rin at unnel (vehicles with anavigation system
only)
The indicator lamp above the grocker
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 above the grocker
switch goes out. Air-recirculation mode deactivates automati-
cally:
Rafter approximately five minutes at outside
temperatures below approximately 41 ‡

The perfume atomizer helps to improve driving
comfort.
Via the multimedia system you can:
Rswitch the perfume atomizer on or off
(Ypage 263)
Rregulate the perfume intensity (Ypage 263).
The following conditions can affect your percep-
tion of the perfume intensity:
Roperating mode of the climate control system
Rinterior temperature
Rtime of year or day
Rair humidity
Rphysiological condition of occupants, e.g. fati-
gue 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 apre-fil-
led vial. You can also choose from avariety 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 packaging.
Do not refill the pre-filled perfume vial when it is
empty. Dispose of the used vial after use.

Ionization
Ionization is used 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 vehicle inte-
rior.
You can switch ionization on or off using the
multimedia system (
Ypage 263).
Ionization can only be operated when the auto-
matic climate control is switched on. The side air
vent on the driver's side must be open.
Air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbitei n
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient 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 ventsi
nto 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 ventsora ir intake grilles in
the vehicle interior.
