Useful information
iThis 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 notethat your vehicle may
not be equipped with all features
described. This also applies to safety-
related systemsand functions.
iRead the information on qualified
specialist workshops: (Ypage 26).
Overview of climatecontrol systems
Important safetynotes
Observethe settings recommendedonthe
following pages. The windows could
otherwise fog up.
To preventthe windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air
dehumidification function
Rswitch 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 (Ypage 141).
iVentilate the vehicle forabrief period
during warm weather, e.g. using the
convenience opening feature (Ypage 89).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
iThe integrated filter filters out most
particles of dust and soot and completely
filters out pollen. It also reduces gaseous
pollutantsand odors.Aclogged filter
reduces the amountofair 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.Asitdepends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet.

Automatic climate control
The following contains notes and
recommendations on optimum use of dual-
zone automatic climate control.
RActivate climate control using the\rand
buttons. The indicator lamps above
the\randbuttons light up.
RSet the temperature to 72‡(22 †).
ROnly use the "Windshield defrosting"
function briefly until the windshieldisclear
again.
ROnly use air-recirculation mode briefly,e.g.
if there are unpleasant outside odors or
when inatunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RUse the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well.The

The 3-zone automatic climate control is only
available on vehicles for Canada.
The following contains instructions and
recommendations to enable you to get the
most out of your automatic climate control.
RActivate climate control using the\rand

Problems with the "Cooling with air dehumidification" function
ProblemPossible causes/consequences andSolutions
The indicator lamp in
thebutton
flashes three times or
remains off. The
"Cooling with air
dehumidification"
function cannot be
switched on.
Cooling with air dehumidification has been deactivated due to a
malfunction.
XVisitaqualified specialist workshop.
Setting climate control to automatic
Points to observe before use
In automatic mode, the set temperature is
maintained automatically ataconstant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
deactivate the cooling with air-
dehumidification function only briefly.
