WARNING
•
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.•
You should not leave recirculated air mode on over a longer period of
time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the inte- rior of the vehicle forms deposits in the
evaporator of the air
conditioning system.
This produces a permanent odour when the air conditioning system is operating which can only be eliminated through considerable effort and expense (replace- ment of compressor).

•
The whole heat output will be needed
to unfrost the windscreen and side
windows. No warm air will be fed to the footwell. This can lead to restriction of the heating comfort.•
The used air streams out through the air removal openings in the luggage
compartment.•
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on
at least once a month for approximately 5 mi
nutes at the highest blower stage - also
during the cold season of the year - in
order to remove such odours. Also open a
window for a short time.•

You should not leave recirculated air mode on over a longer period of time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an acci-dent increases. Switch recirculated air mode off as soon as the windows begin misting up.Using the air conditioning system economicallyThe compressor on the air co
nditioning system uses po
wer from the engine when
in cooling mode which will effect the fuel consumption. It recommended to open the windows or the doors of a vehicle for which the inte- rior has been strongly heated through the ef
fect of direct sunlight in order to allow
the heated air to escape. The cooling system should not be switched on while travelling when the window is open. The desired interior temperature can also be achieved without switching in the cooling system just by switching to fresh air mode.

For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.
Operational problemsIf the cooling system does not operate at outside temperatures higher than +5 °C, there is a problem in the system. The reasons for this may be:•
The fuse on the air conditioning system
has blown. Check the fuse, replace it if
necessary
⇒page 258.
•
The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot
⇒page 18.
If you are not able to rectify the operat
ional problem yourself, or if the cooling
capacity decreases, switch the cooling sy
stem off. Contact a specialist garage.
Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains fully automatically a convenience temperature. This is achieved by automatically varying the temperature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which eliminates the need to alte
r the settings manually. The
automatic mode

⇒ page 117 ensures maximum wellbeing of th
e occupants at all times of the year.
Description of Climatronic system The cooling operates only if the following conditions are met:•
engine running,
•
outside temperature above approx. +2°C,
•
switched on.
If the cooling system is switched on, th
e temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of
the car is enhanced as a result of this
particularly at high outside temperatur
es and a high air humidity. The system
prevents the windows misting up during the cold season of the year. The heating effect is dependent upon th
e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature. It is possible to briefly activate recirc
ulated air mode in order to enhance the
cooling effect
⇒page 118.
The air inlet in front of the windscreen must
be free of ice, snow or leaves in order
to ensure that the heating and cooling systems operate properly. The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine. After switching on the cooling
Condensation
from the evaporator of the air condi-
tioning may drip down and form a puddle be
low the vehicle. This is quite normal
and not an indication of a leak! Recommended setting for all periods of the year:•
Set the desired temperature, we recommend 22 °C.

Move the air outlet vents
3 and
4, so that the air flow
is directed slightly
upwards. Aeration of the vehicle when ignition is switched off* On models fitted with power sliding/tilting roof with solar cells, the fresh air blower is automatically switched over
to “solar mode” if the sun ray's are sufficient after
switching off the ignition. The solar cells on
the sliding/tilting roof deliver power for
the fresh air blower. This supplies the interior of the car with fresh air. For an optimum ventilation, the air outlet vents
3 and
4 must be opened
⇒ page 108, fig. 137
.
The ventilation functions only when
the sliding/tilting roof is closed.

that differing temperatures for the left and right side can be set.
If the warning light in the button lights up, the temperature for both sides cannot be set with the control dial . You
can reinitiate this function by pressing
the button . The warning light in the bu
tton which indicates the possibility to
set differing temperatures for the left and right side, goes out. You can set the interior temperature be
tween +18°C and +26°C. The interior
temperature is regulated automatically within this range. If you chose a tempera- ture lower than +18°C, a blue symbol lights
up at the start of the numerical scale. If
you chose a temperature higher than +26°C,
a red symbol lights up at the end of
the numerical scale. In both limit positi
ons the Climatronic operates at maximum
cooling or heating capacity, respectively.
The temperature is not controlled in this
case.

Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.Recirculated air mode In recirculated air mode air is sucked
out of the interior of the vehicle
and then fed back into the interior. When the automatic air distribu-tion control is switched on, an air quality sensor measures the concentration of pollutants in the drawn-in air.Recirculated air mode prevents polluted air outside the vehicle from getting into the vehicle, for example when driving through a tunnel or when standing in a traffic jam. If a considerable increase in concentration of pollutants is recognized by the ai
r quality sensor, when the automatic
air distribution control is switched
on, the air distribution control will
temporarily be switched off. If the concentration of pollutants decreases to the normal level, the air distributi
on control is automatically switched
off so that fresh air can be guided into the vehicle interior. Switching recirculated air mode on – Press the button repeatedly until the warning light on the left
side of the button lights up.
Switch on automatic air distribution control – Press the button repeatedly until the warning light on the right
side of the button lights up.
Switch off automatic air distribution control temporarily – If the air quality sensor does not sw
itch on the air distribution control
automatically when there is a nausea
ting smell, you can switch it on
yourself by pressing the button *.
The warning light lights up in
the button on the left side.
Switching recirculated air mode off – Press the button or press the button repetitively, until the
warning lights in the button go out.
WARNING
You should not leave recirculated air mode on over a longer period of time, as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an acci- dent increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
If the windscreen mists up, press the button
⇒page 116, fig. 141
.
After the windscreen has been demisted, press the button .•
The automatic air distribution control operates only if the outside temperature
is higher than approx. 2°C.Controlling blower There are a total of seven blower stages available.The Climatronic system controls the bl
ower stages automatically in line
with the interior temperature. You
can also, however, adapt the blower
stages manually to suit your particular needs. – Press again the button on the left side (reduce blower speed) or on
the right side (increase blower speed).
If you switch off the blower, th

Auxiliary heating (auxiliary heating and ventilation)*Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or supplies the interior of the vehicl
e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating) The auxiliary heating (auxiliary heating) f
unctions in connection with the Climatic or
Climatronic. It can be used when stationa
ry, when engine is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The auxiliary heating (auxiliary heating)
warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed is not set to zero) flows into the occupant compartment. Auxiliary ventilation The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching off the engine, whereby the interior temperature is effectively decreased (e.g. with the vehicle parked in the sun).
WARNING
•
The auxiliary heating must never be operated in closed rooms - risk of
poisoning!•
The auxiliary heating must not be running during refueling - risk of fire.
•
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the
vehicle, if you wish to operate the
auxiliary heating, in su
ch a way that the exhaust gases of the auxiliary
heating can come easily into contact
with inflammable materials (e.g. dry
grass) or easily inflammable su
bstances (e.g. fuel run out).
Note
•
If the auxiliary heating runs, the fuel
consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be operated, if there is very little fuel in the tank.•
The exhaust pipe of the auxiliary heating,
which is located on the underside of
the vehicle, must not be clogged and
the exhaust flow must not be blocked.
•
If the auxiliary heating and
ventilation is runni
ng, the vehicle battery discharges.
If the auxiliary heating and ventilation
has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the vehicle battery.•
The auxiliary heating only switches the bl
ower on, if it has achieved a coolant
temperature of approx. 50 °C.•
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.
