•
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
compartment.•

Note
If the windscreen mists up, press the button
⇒page 90, fig. 102
. After the
windscreen has been demisted, press the button .Setting temperatureYou can set the interior temperature randomly with the buttons and
.
You can set the interior temperature between +18°C (64°F) and +29°C (84 °F). The interior temperature is regulated automatica
lly within this range. If you select the
temperature below +18°C (64 °F), “LO” appe
ars in the display. If you select the
temperature higher than +29°C (84 °F), “H
I” 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 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.
– Press the button or

in order to decrease or
increase the speed.
If you switch off the blowers, th
e Climatronic is switched off and
OFF
is shown in
the display. The set blower speed is indicated by the lighting up of the respective number of bars at the point .
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.
