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 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).
Using the systemSetting temperature– Turn the control dial fig. 96 to the right in order to increase the temperature.
– Turn the control dial to the left in order to increase the temperature.Controlling blower– Turn the blower switch into one of the po sitions, 1 to 4, in order to switch the
blower on.
– Turn the blower switch into position 0 in order to switch the blower off. – IF you wish to close the inlet for fresh air, use the switch - Recirculated air
mode page 82.
Control for air distribution– You can adjust the direction of the air flow using the air distribution control
page 77.switching cooling on and off– Press the button fig. 96 . The warning light lights up in the button.
– When you again press the switch , the cooling system is switched off. The warning light in the button goes out.
Note
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 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.

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 page 80, fig. 96 - the warning light lights up in the button.Switching recirculated air mode off– Press again the button - the warning light in the button goes out.
The button cannot be pressed if the control dial is in the position
or close
to this position.
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.Using the air conditioning system economicallyThe compressor on the air conditioning syst em uses power 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 interior
has been strongly heated through the effect 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.Climatronic* (automatic air conditioning)Description
The Climatronic system is a combinat ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains a constant temp erature fully automatically, once it has
been set. 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 bright
sunlight which eliminates the need to alter the settings manually. The automatic
mode page 84 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 +5 °C,
the button is not pressed.
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 partic-
ularly 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 the coolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculat ed 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.

Technical Data
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!
If you make a change before switching off the ignition, which differs from the auto-
matic mode, the changed functi ons remain stored. Only the function “circulating air”
is erased 20 minutes after switching off the ignition.
Recommended setting for all periods of the year:
Set the temperature to 22 °C (72 °F).

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 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

Operational problemsIf all the symbols on the display of the au tomatic air conditioning system flash for
approx. 15 seconds after switching on the igniti on, then there is a fault in the system -
visit a specialist garage.
If the cooling system does not oper ate, the following faults may exist:
the outside temperature is lower than +5°C,
The compressor of the automatic air conditioning system was temporarily
switched off due to a too high temperature of the coolant,
a blown fuse.
Check the fuse, replace it if necessary page 177. If a blown fuse is not the source of
the fault, switch the Climatronic off and have it checked.
If the cooling capacity decreases, switch the Climatronic off and have it checked.

Technical Data
Starting-off and DrivingSetting steering wheel positionYou can set the height and the forward/back position of the steering wheel to the
desired position.
– Adjust the driver seat page 56.
– Pull the lever below the steering wheel down fig. 98 , .
– Set the steering wheel to the desired position concerning height and
forward/back position .
– Then push the lever up against the steering column until it locks into place.
WARNING
You must not adjust the steering wheel when the vehicle is moving!
The driver must maintain a distance of at least 25 cm to the steering wheel
fig. 99 . Not maintaining this minimum distance will mean that the airbag
system will not be able to properly protect you - hazard!
For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its position uninten tionally when driving - risk of acci-
dent!
If you adjust the steering wheel furthe r towards the head, you will reduce
the protection offered by the driver airbag in the event of an accident. Check
that the steering wheel is aligned to the chest.
When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock po sition. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the
steering wheel or at the inne r steering wheel edge). In such cases, injuries to the
arms, the hands and the head can occur when the driver airbag is deployed.
