The A/C compressor will not
activate unless the outdoor
temperature is above 55°F
(+13°C).
–This function saves fuel by
delaying the activation of the
A/C compressor. However,
in wet weather it is advisable
to have the A/C compressor
running when outdoor tem-
peratures are below
57
°F
(+14
°
C), as the A/C system
reduces the likelihood of the
windows fogging up.
A/C compressor cuts
in when outdoor tem-
perature is above 41°F
(+5°C)
Recirculation will be swit-
ched on if the speed of the
car is less than 6 mph (10

when the speed has risen
above 20 mph (30 km/h), but
not if the ECON mode has
been programmed according
to ”Programming II”.
To prevent misting, this func-
tion is disengaged at outdoor
temperatures lower than
45°F (+7°C) and engaged at

(+10°C).
–This function is useful to
prevent fumes being drawn
into the car in traffic jams.
Recirculation is swit-
ched on about
45 seconds after star-
ting if the outdoor tem-
perature is above 86°F
(+30
°
C) and the selec-
ted temperature for the
cabin is well below the
actual temperature in
both temperature
zones.
The heating will come on
about five seconds after the
engine has started if the out-
door temperature is below
41°F (+5°C).
–This function helps to pre-
vent ice or mist forming on
the rear window in cold,
damp weather. Fuel con-
sumption may increase
slightly.
Rear-window heating
can only be switched
on manually.
