achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-

switched off (Y page 167).
i Ventilate the vehicle for
abrief period
during warm weather, e.g. using the con-
venience openin gfeature (Y page 111).
This will speed up the coolin gprocess and
the desired interior temperature will be
reached more quickly. i
The integrated filter filter
sout most par-
ticles of dust and soot and completely fil-
ter sout pollen. It also reduces gaseous pol-
lutant sand odours. Aclogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason ,you should always
observ ethe interval for replacin gthe filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climat econtrol. 156
