Optimum use of 3-zone automatic cli-
mate control
3-zone automatic climate control The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
R Activate climate control using the 0058
rocker switch. The indicator lamp above
the 0058 rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic
mode. If necessary, activate this function
(Y page 143).
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion 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 oth-
erwise 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 deac-
tivated with the ignition switched off. The
residual heat function is switched off when the ignition is switched on.
AGILITY SELECT switch You can choose between various drive pro-
grams with the AGILITY SELECT switch
(Y page 167).
If you have selected the drive program E, the
climate control switches to Eco mode.
In Eco mode:
R the cooling output is reduced when cooling
R when heating, the electrical heater booster
is deactivated and heat output is reduced
as a result
R the rear window defroster running time is
reduced If you have selected the drive program
C,Sor
S+ the climate control switches to Comfort
mode. The current climate control settings
are maintained in Comfort mode.
ECO start/stop function During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Y page 162). Operating the climate control sys-
tems Switching climate control on/off
General notes When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could fog up.
Therefore, switch off climate control only
briefly
Switch on climate control primarily using the 0058 rocker switch (Y page 144).
Switching on/off X
Turn the SmartKey to position 2in the igni-
tion lock (Y page 157).
X To switch on: press the008A/!
rocker switch up or down.
The Audio 20/COMAND climate control
menu opens.
X Activate the climate control using the air-
conditioning function bar; see the separate
Audio 20/COMAND operating instruc-
tions.
or

instructions.
or X Set the airflow to level 0 using the H
rocker switch. Activating/deactivating cooling with
air dehumidification
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.
Activating/deactivating X
To activate: press the005Arocker switch
up or down.
The indicator lamp above the rocker switch lights up.
or
X Activate the cooling with air dehumidifica-
tion function via Audio 20/COMAND (see
the separate operating instructions). X
To deactivate: press the005Arocker
switch up or down.

is malfunctioning. ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped under certain conditions.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.

R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
All of the vehicle's systems remain active
when the engine is stopped automatically.
The HOLD function can also be activated if the engine has been switched off automatically. Itis then not necessary to continue applying the
brakes during the automatic stop phase.
When you depress the accelerator pedal, the engine starts automatically and the braking
effect of the HOLD function is deactivated.
The engine can be switched off automatically
a maximum of four times (first stop and three subsequent stops) in succession.
Automatic engine start The engine starts automatically if:
R you switch off the ECO start/stop function
by pressing the ECO button.
R you switch to drive program S+.
