Programming II
It is also possible to customize the ACC system, e.g. to adapt to
driving and weather conditions.
Function Operation in AUTO mode
after Programming II
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.
Recirculation will be
switched on if the speed of
the car is less than 6 mph (10
km/h) and will be switched off
when the speed has risen
above 20 mph (30 km/h), but
not if the ECON mode has
been programmed according
to "Programming II".
–This function is useful to
prevent fumes being drawn
into the car in traffic jams.
Standard operation
in AUTO mode

in when outdoor tem-
perature is above 41°F

Recirculation is
switched on about
45 seconds after start-
ing if the outdoor tem-
perature is above 86°F
(+30 C) and the
selected temperature
for the cabin is well
below the actual tem-
perature in both tem-
perature 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.
