Overview of climate control systemsClimate control

Optimum use of automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone auto-
matic climate control or 3-zone automatic cli-
mate control.
R You can switch on climate control by using the
0058 and005A or0058 and0056 buttons.
The indicator lamps in the 0058and
005A buttons or the 0058and0056 buttons
light up.
R Vehicles with 3-zone automatic climate
control: in automatic mode, you can also use
the 00F0 button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The MEDIUM
level is recommended.
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 Vehicles with 3-zone automatic climate
control: use the ZONE function to adopt the
temperature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the 00D6 button goes out.
R Vehicles with 3-zone automatic climate
control: use the "residual heat" function if
you want to heat or ventilate the vehicle inte- rior when the ignition is switched off. The
residual heat function can only be activated or
deactivated with the ignition switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output, you can switch off the ECO start/stop function
by pressing the ECO button (Y page 140). Operating the climate control sys-

In the rear compartment, you can also switch
climate control on and off using the 0058and
0078 buttons.

General notes You can deactivate the flow of fresh air if
unpleasant odors are entering 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.

General notes The residual heat function is only available on
vehicles for Canada.
It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutes after the engine has been switched off. The heating time depends on
the set interior temperature.

Ionization is used to purify the air in the vehicle interior and attain an improved interior climate. Operating the climate control systems
131Climate control

The ionization of the interior air is odorless and
cannot be perceived directly in the vehicle inte- rior.
You can switch ionization on and off via the mul-
timedia system (see the Digital Operator's Man-
ual).
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. Setting the air vents
Important safety notes
G
WARNING
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:
R keep the air inlet grille on the hood and in the
engine compartment on the front-passenger
side free of blockages, such as ice, snow or
leaves.
R never cover the air vents or air intake grilles in
the vehicle interior.
i For virtually draft-free ventilation, adjust the
sliders of the air vents to the center position. Setting the center air vents
