Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 24).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
otherwise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 133).
i When the weather is warm, ventilate the
vehicle for a brief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly. i
The integrated filter can filter out most
particles of dust, and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet. 122

Air-conditioning system Below, you can find a number of notes and
recommendations to help you use the air-

R Switch on climate control using the 005A
button. The indicator lamp in the 005A
button lights up.
R Set the temperature to 72 ‡ (22 †).
R Recommendation for air distribution in
winter: set the009Band0061 settings.
Recommendation for air distribution in
summer: set the009Csetting.
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.
ECO start/stop function During automatic engine switch-off, the ECO
start/stop function only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop function
