Notes on using automatic climate
control
Climate control system Below, you can find a number of notes and rec-
ommendations to help you use climate control
optimally. R
Activate climate control using the X
rocker switch. The indicator lamp in the X
rocker switch lights up. R
Set the temperature to 72 ‡ (22 †). R
Only use the "Windshield defrosting" function
briefly until the windshield is clear again. R
Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode. R
Use the residual heat function if you want to
heat or ventilate the vehicle interior when the
ignition is switched off. The residual heat
function can only be activated or deactivated
with the ignition switched off. The residual
heat function is switched off when the ignition
is switched on.
If you are controlling the rear-compartment cli-
mate control using the front control panel, note
the following: R
If you set rear-compartment climate control
using the front control panel, the

three times or remains
off. Cooling with air
dehumidification can
also no longer be activa-
ted using the multimedia
system (see the sepa-
rate operating instruc-
tions). Cooling with air dehumidification has been deactivated due to a mal-
function. X
Visit a qualified specialist workshop.
Setting climate control to automatic
General notes In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.
Controlling front climate control auto-
matically using the front control panel X

Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged. 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.
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.
Activating/deactivating X
Turn the SmartKey to position 2 in the ignition
lock ( Y
page 162).X
To activate: press the r rocker switch up
or down.
The indicator lamp in the r rocker switch
lights up.
Air-recirculation mode switches on automati-
cally: R
at high outside temperatures R
at high levels of pollution R
in a tunnel
The indicator lamp in the r rocker switch is
not lit when automatic air-recirculation mode is
activated. Outside air is added after about
30 minutes. X
To deactivate: press the r rocker switch
up or down.
The indicator lamp in the r rocker switch
goes out. Air-recirculation mode deactivates automati-
cally: 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 Vehicles with rear-compartment climate
control: 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
rear and front compartment of the vehicle for
approximately 15 minutes. If the "Residual heat"
function is set for only the front or only the rear
compartment, it is possible to continue heating
or ventilating for approximately 30 minutes.
Vehicles without rear-compartment climate
control: 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 approx-
imately 30 minutes.
The heating or ventilation time depends on the
temperature that has been set.152

The perfume atomizer helps to improve driving
comfort.
Via the multimedia system you can: R
switch the perfume atomizer on or off R
regulate the perfume intensity (see the sepa-
rate operating instructions)Operating the climate control systems 153
Climate control Z

The following conditions can affect your percep-
tion of the perfume intensity: R
operating mode of the climate control system R
interior temperature R
time of year or day R
air humidity R
physiological 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 a pre-fil-
led 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 packaging.
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 326).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 yourself. X
Fill the perfume vial with a maximum of
0.5 fl. oz. (15 ml) of the desired liquid per-
fume. 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.154
