For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.
Operational problems
If 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 243.
•The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot ⇒ page 11.
If you are not able to rectify the operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling system 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 a constant temperature fully automatically, once it has
been set. This is achieved by automa tically varying the temperature of the
outflowing air, the blower stages and the air distribution. The system also takes into
account bright sunlight which eliminates the need to alter the settings manually.
The automatic mode ⇒ page 110 ensures maximum wellbeing of the 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 +2 °C,
•the button is not pressed.
If the cooling system is switched on, the 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 temperatures 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 recirculated air mode in order to enhance the
cooling effect ⇒.
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 high 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 below the vehicle. This is quite normal
and not an indication of a leak!
Recommended setting for al l periods of the year:
•Set the temperature to 22 °C (72 °F).
•Press the button ⇒page 109, fig. 125 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards
⇒ page 112, fig. 126 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 109, fig. 125 . The informa-
tion in the desired temperature measuring unit appears in the display.
WARNING
•For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mist ing. Please familiarize yourself about
how to correctly operate the heating an d 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
•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 minutes 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.
•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 co nsiderable effort and expense (replace-
ment of compressor).
•The used air streams out through the air removal openings in the luggage
compartment.
•The Information of the Climatronic is displayed on the display of the radio*. You
can also switch off this function - see operating instructions for radio

The temperature control is controlled automatically. More air flows out of the air
outlet vents 1 and 2.
Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.
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.
Switching recirculated air mode on
– Press the button - the warning light lights up in the button.
Switching recirculated air mode off
– Press again the button or the button - the warning light in
the button goes 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 109, fig. 125 . After the
windscreen has been demisted, press the button .
Setting temperature
You can separate the interior temperature for the left and right side sepa-
rately.
– You can set the temperature for both sides after switching on the igni- tion with the control dial .
– If you wish to set the temperature for the right side, turn the control dial .
If the temperature for the right side was set via the control dial , it can no longer
be set via the control dial - temperature fo r both sides. This is only possible if
you press the button for about 2 seconds.
You can set the interior temperature between +16 °C (60 °F) and +29,5 °C (85 °F).
The interior temperature is regulated automatically within this range. If you select
the temperature below +16 °C (60 °F), “LO” appears in the display. If you select the
temperature higher than +29,5 °C (85 °F), “HI” appears in the display. In both limit
positions 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 temperat ure, for example when getting out of the
vehicle, can result in chills in sensitive persons.
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.
– Turn the control dial ⇒page 109, fig. 125 to the left (reduce
blower speed) or right (increase blower speed).
Switch off the blowers, the Climatronic is switched off and in the display shows OFF.

Auxiliary heating system (auxiliary heating and
ventilation)*
Description
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 heater or
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 (e.g. 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 cool ant warms up the air, which (if the blower
speed is not set to zero) flows into the occupant compartment.
6)
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching on the blower, if the blower speed is not set to zero, whereby the interior
temperature is effectively decreased (e.g. with a vehicle parked in the sun).
Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.
Basic setting
– In the information display, select from the menu Main menu the
Menu Setup (settings) ⇒ page 19, fig. 11 .
– In the menu Settings select the menu Aux. Heating (auxiliary
heating).
– In the menu Aux. Heating (auxiliary heating) ⇒ fig. 128 select the
menu Weekday and set the current day.
– Return to a higher level by selecting the menu Back, i. e. in the menu
Aux. Heating (auxiliary heating) .
– In the menu Aux. Heating select the menu Running time and set the
desired operating period in steps of 1 minute. The operating period
can be 5 to 60 minutes.
– Return to a higher level by selecting the menu Back in the menu
Aux. Heating .

Programming
For the programming of the auxiliary heatin g (auxiliary heating and ventilation) in
the menu Aux. Heating there are three pre-set times:
•Pre-set time 1
•Pre-set time 2
•Pre-set time 3
In each pre-set time, the day (if necessary each day = daily) and the time (hour and
minute) can be set for the operating period of the auxiliary heating and/or ventila-
tion.
If you leave the pre-se t menu by selecting menu Back or do not operate the display
for longer than 10 seconds, the set values are stored, but the pre-set time is not
active.
Both other pre-set times can be prog rammed and stored in the same way.
If you select the menu Activate after setting the desired values, Pre-set time
(weekday, hours, minute) activated! is displayed in the display and the set pre-
set time is active.
Only one programmed pre-set time can be active.
The last programmed pre-set time remains active.
The active pre-set time can be changed in the menu Aux. Heating in the menu
Activation by selecting a pre-set time.
The prerequisite for the correct switching on of the auxiliary heating (auxiliary
heating and ventilation) according to the programmed pre-set time is the correct
setting of the current time ⇒page 14 and weekday ⇒page 113.
If the system is running, a warning light in the button for direct switching on/off of
the auxiliary heating lights up. The running system deactivates after expiration of the operating period or is deac-
tivated earlier by pressing the button for
direct switching on/off of the auxiliary
heating ⇒page 114.
The deactivation of a desired pre-set time can be performed by selecting the menu
Deactive in the menu Active .
It is possible to re-establish the factory setting using the menu Fa ct or y se t tin g in
the menu Aux. Heating .

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 such 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 heat ing and ventilation is running, 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 sw itches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
•At low outside temperatures, this can resu lt in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
•After switching off the auxiliary heating, the coolant pump runs for a short
period.
•The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicate s a low loading state.
•The auxiliary heating (auxiliary heating) switches on, if in the information
display: Please refuel! is indicated or was indicated before switching off the igni-
tion.
•When driving, the auxiliary heating can only be switched on, if the exterior
temperature is lower than 5 °C.
•The air inlet in front of the windscreen mu st be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
•So that the warm air can flow into the vehicle interior after switching on the
auxiliary heating (auxiliary heating), the control dial ⇒page 100, fig. 119 must
be turned up to the stop to the right when heating. With Climatic and Climatronic,
you can maintain the temperature norma lly selected by you (we recommend 22
°C). It is recommended to put the air flow in the position
. For heating and
climatic put the blower switch ⇒page 100, fig. 119 if necessary ⇒page 104,
fig. 122 in the position 2.
•On vehicles with DPF (die sel particle filter) the warm coolant heats up the
engine.
