Useful information
i This Operator's manual describes all
models and all standard and optional equip- ment 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 special-
ist workshops (Y page 26). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise 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 dehumidifi-
cation 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 acti-
vated 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 filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odors. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve 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-
conditioning system optimally.
R Switch on cooling with air dehumidification
using the 005Abutton. The indicator lamp
in the 005Abutton 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" 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.
ECO start/stop function During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop function can be deactivated by pressing the ECO but-
ton (Y page 147). 124
