will speed up the cooling process and the
desired vehicle interior temperatur ewill be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filter sout
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observ ethe
interva lfor replacing the filter ,which is
specifie dinthe Servic eBooklet .Asit depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Servic eBooklet.

Important information The coolin
gwith air dehumidification function
is only available when the engin eisrunning.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. G
Risk of accident
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may preven tyou from observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when THERMOTRONI Cisincool-
ing mode. This is norma land not asign that
there is amalfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefor edoes not damage the ozone
layer.

Problems with the "cooling with air
dehumidification" function If the indicator lam
pint he ¿ button does
not go out when switched off ,the cooling with
air dehumidification func tion is switched off
due to amalfunction. You can no longer

In order to ensure the direct flow of fresh air
through the air vent sinto the vehicl einterior,
please observe the following notes:

lnote
When toppin guptheoil, tak ecaren ot to spill
any .Ifo il enter sthe soil or waterways, it is
harmful to the environmen t.Engine oil cap (example)
X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 –2litres.
! Do not add too muc hoil. If the oil level is
above the "max "mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter .Have excess oil siphoned off.
