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 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.

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 temp
erature fully automatically, once it has
been set. This is achiev
ed by automatically varying the temperature of the
outflowing air, the blower stages and the ai
r distribution. The system also takes into
account bright sunlight which eliminates
the need to alter the settings manually.
The
automatic mode
⇒page 90 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, 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 outs
ide 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 recirc
ulated 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 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 functions 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).

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
•
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.

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 used air streams out through the air removal openings in the luggage

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 temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.Controlling blower There are a total of six 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.

WARNING
•
“Stale air” may result in fatigue in
the driver and occupants, reduce
attention levels and also cause the windows to mist up. The risk of having an accident increases.•
Do not switch the Climatronic syst
em off for longer than necessary.
•
Switch the Climatronic system on as soon as the windows mist up.
Operational problemsIf all the symbols on the display of the au
tomatic air conditioning system flash for
approx. 15 seconds after switching on the ignition, 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 192. 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.

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 switched on low beam or
main beam or other electrical compon
ents with major power consumption are
briefly switched off. 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.
WARNING
•
When driving, the ignition key must always be in the position (igni-
tion 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 unex- pected locking of the steerin
g wheel - risk of accident!
•
Do not withdraw the ignition key from the lock until the vehicle has come
to a stop. The steering lock can en
gage immediately - risk of accident!
•
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 engine
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 an
d put on the handbrake firmly before
starting the engine.•
The clutch pedal should be fully depr
essed when starting the engine - the
