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 standi ng in a traffic jam.Switching recirculated air mode on– Press the button - the warning light lights up in the button page 97, fig. 101 .Switching recirculated air mode off– Press again the button - the warning light in the button goes out.
The recirculated air mode is switched off automatically if the air distribution control
is in position
page 97, fig. 101. You can also switch recirculated air mode on
again from this setting by repeatedly pressing button .
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 atten-
tion 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.Climatic* (semi-automatic air conditioning system)Description
The Climatic is a combined coolin g and heating system. It makes it
possible to optimally control the air temperature at any season of the
year.Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is operating
properly. The cooling only operat
es if the button fig. 102 is pressed, and the following
conditions are met:
engine running,
outside temperature above approx. +2°C and
blower switch switched on (positions 1 to 4).
Air at a temperature of about 5°C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of the
air flow out of the vents and large differences in temperature, for example when getting
out of the vehicle, can result in chills in sensitive persons.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 interior
of the vehicle forms deposits in the evapor ator 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 (replacement of
compressor).

– When you again press the switch , the cooling system is switched off. The warning light in the button goes out.Rear window heater– Press button . Further information page 62, “Rear window and wind-
screen heater”.Auxiliary heating (auxiliary heating)– Press the button in order to directly switch on/off the auxiliary heating
(auxiliary heating and ventil ation. Further information page 105, “Auxiliary
heating (auxiliary heat ing and ventilation)*”.
The set temperature will be automatically maintained other than when the
control dial is on the extreme right or extreme left position:
Extreme right position - full heating;
Extreme left position - full cooling;
The blower should aways be on to prevent the windows from misting up.Note
The whole heat output will be needed to unfrost the windscreen and side windows.
No warm air will be fed to the footwell. Th is can lead to restriction of the heating
comfort.
The used air streams out through the air removal openings in the luggage compart-
ment.
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 avoid such odours. Also open a window
for a short time.

Climatronic* (automatic air conditioning)Description
The Climatronic system is a combination of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains fu lly automatically a convenience temperature. This is
achieved by automatically varying the temper ature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which elim-
inates the need to alter the settings manually. The
automatic mode page 103
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 approx. +2°C,
switched on.
The AC compressor is switched off at a high coolant temperature in order to provide
cooling at a high load of the engine.
Recommended setting for all periods of the year:
Set the desired temperature, we recommend 22°C.
Press the button fig. 103 .
Move the air outlet vents 3 and 4 page 96, fig. 99 , so that the air flow is directed
slightly upwards.Note
On vehicles equipped with a factory-fitted radio* or navigation*, the information
of the Climatronic is also shown on the display. This function can be switched off, see
operating instructions of the radio* or the navigation system*.

Climatronic.
When pressing again the button , the Climatronic changes into the “LOW” mode
and the warning light in the top left corner lights up. The Climatronic uses only in this
mode the lower blower speed. However taking into account the noise level, this is
more comfortable, yet be aware that the effectiveness of the air conditioning system is
reduced particularly if th e vehicle is fully occupied.
By pressing again the button , yo u change into the “HIGH” mode.
The automatic mode is switched off by pres sing the button for the air distribution or
increasing or decreasing the blower speed. The temperature is nevertheless
regulated.

active when no lower temperature than the outside temperature can be reached.Setting temperatureYou can separate the interior temperature for the left and right side separately.
– You can set the temperature for both sides after switching on the ignition with the
control dial .
– If you wish to set the temperature for the right side, turn the control dial . The warning light in the button lights up, this indicates that differing tempera-
tures 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 button which indicates the possibility to set
differing temperatures for the left and right side, goes out.
You can set the interior temperature between +18°C and +26°C. The interior temper-
ature is regulated automatically within this range. If you chose a temperature 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 positions the Climatroni c operates at maximum cooling or heating
capacity, respectively. The temperatur e is not controlled in this case.
Lengthy and uneven distri bution 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 distribution
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 tunn el or when standing in a traffic jam. If
a considerable increase in concentration of pollutants is recognized by the air quality
sensor, when the automatic air distribution co ntrol is switched on, the air distribution
control will temporarily be switched off. If the concentration of pollutants decreases to
the normal level, the air distribution 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 switch on the air distribution control automatically
when there is a nauseating 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.

Controlling blower
There are a total of seven blower stages available.The Climatronic system controls the blower st ages automatically in line with the inte-
rior temperature. You can also , however, a dapt the bl ower stages ma nua lly to suit y our
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, the Climatronic is switched off.
The set blower speed is displayed above the button when the respective number
of warning lights come on.
WARNING
“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.
Do not switch the Climatronic system off for longer than necessary.
Switch the Climatronic system on as soon as the windows mist up.

The temperature control is controlled automatically. More air flows out of the air outlet
vents 1 and 2.Auxiliary heating (auxiliary heating and ventilation)*Description and important information
The auxiliary heating (auxiliary he ating 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) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The engine is also preheated when the vehicle is stationary and the engine is switched
off, if the auxiliary heating is switched on.
The auxiliary heating (auxiliary heating) wa rms up the coolant during the combustion
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).

– In the menu Aux. heating select the menu point Mode.
– In the menu Mode select the desired mode Heating for or Ventilation for .ProgrammingFor the programming of the auxiliary heating (auxiliary heating and ventilation) in the
menu Aux. heating (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 and the time (hour and minute) can be set for switching
on the auxiliary heating and/or ventilation.
An empty position can be fo und between Sunday and Monday when selecting the day.
If this empty position is selected, the activation is performed without taking into
account the day.
If you leave the pre-set menu by selecting the menu Back or do not make changes on
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.

Pre-set time (weekday, hours, minute) activated. 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.
After the auxiliary heating activates at the set time, it is necessary to pre-set a time
again.
Changing the active pre-set time is carried out after selecting the menu point Activate
in the menu Aux. heating (auxiliary heating) 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

You should not switch on any major elec trical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering wheel until the
steering locking pin is heard to engage. You should always lock the steering as a general
rule if you leave your vehicle. This acts as a deterrent against possible theft of your
vehicle .
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot
easily be turned into this position, in order to release the steering lock.
Position
The engine is started in this position. At the same time, major electrical components
are switched off for short periods. The ignition key moves back into position when
one releases the key.
The ignition key must be turned back into position each time before starting the
engine again. The starter repeat lock in th e ignition lock prevents the starter being
engaged when the engine is r unning and thus getting damaged.
Ignition key withdrawal lock (automatic gearbox)
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P.
WARNING
When driving, the ignition key must always be in the position (ignition
switched on) without the engine running. This position is indicated by the
warning lights coming on. If this is not the case, it could result in unexpected
locking of the steering wh eel - risk of accident!
Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (by applying the handbrake or moving the selector lever
into the position P). The steering lock can engage imme diately - risk of acci-
dent!
Always withdraw the ignition key if you are going to leave the vehicle, even
for a short time. This is particularly important if children are left in the vehicle.
The children might otherwise start the engi ne or switch on electrical equipment
(e.g. power windows) - risk of accident or injury!
Starting the engineGeneral
You can only start the engine only using an original ignition key.
Place the gearshift lever into neutral (or place the selector lever to the position P or
N in the case of an automatic gearbox) and put on the handbrake firmly before starting
the engine.
Before starting, it is necessary to depres s the clutch pedal and to hold it pressed
until the engine starts. If you start the engi ne without depressing the clutch pedal, the
engine does not start and a message is show n in the display of the instrument cluster
to remind you of th e necessity to depress the clutch pedal.
Let go of the key as soon as the engine starts otherwise there may be damage to
the starter.
The engine running noises may louder at first be louder for a short time after starting
the cold engine until oil pressure can be built up in the hydraulic valve clearance
compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid page 228.
It is only possible to tow-start vehicles fitt ed with a manual gearbox. The tow-starting
distance must not be more than 50 metres page 231.
WARNING
Never run the engine in non ventilated or enclosed areas. The exhaust gases
of the engine contain besides the odorless and colourless carbon monoxide a
