Action
IMPORTANTIf the ¬warning light
does not turn on when turning the ig-
nition key to MARor if it stays on
when travelling, (together with mes-
sage on display) this could indicate a
failure in safety retaining systems; un-
der this condition air bags or preten-
sioners could not trigger in the event of
collision or, in a restricted number of
cases, they could trigger accidentally.
Stop the car and contact Lancia Deal-
ershipto have the system checked im-
mediately.

WARNING ICE HAZARDMeaning of the message
Outside temperature is low
and there could be ice on the roadRemarks
Under certain conditions
(bridges, overbridges,
curves or road sections in
the shade, etc.) the air temperature
at ground level can be lower than
that at sensor level and therefore
there can be ice on the road
although this warning message is
not displayed

AUTOMATIC
CLIMATE
CONTROL SYSTEM
GENERAL
The car can be equipped with a
two-zone or multi-zone automatic
climate control system.
The two-zone climate control sys-
tem controls temperature, air distri-
bution and flow inside the passenger
compartment in two areas: driver
side and passenger side.
The multi-zone climate control sys-
tem controls temperature, air distrib-
ution and flow inside the passenger
compartment in three areas: driver
side, passenger side or back-seat pas-
sengers.
Control of front-seat passenger and
back-seat passengers is alternated;
when the button led REARis turned
off, the front-seat passenger control
is operating, whereas when button
REARis pressed (button led turned
on), the back control panel is acti-
vated, thus excluding those for the
front-seat passenger.Temperature check is based on the
“heat balance” concept, which
means that the system works con-
stantly to keep a regular balance
between incoming and outgoing heat
energy, in order to stabilize temper-
ature inside the passenger compart-
ment and compensate possible vari-
ations of outside climate, sun radi-
ance included. For optimal control
of temperature in the two areas of
the passenger compartment, the sys-
tem is equipped with a sun ray sen-
sor.
The system features a pollution
sensor which can automatically
switch the air recirculation function
on to reduce the unpleasant effects
of polluted air in cities, queues, tun-
nels and when the windscreen wash-
er is operated (with the characteris-
tic smell of alcohol).
The air quality is controlled by an
active carbon dust/pollen filter
which has the double function of
mechanically filtering the particles
dispersed in the air and attenuating
the peak accumulation of certain
pollutants.Parameters and functions auto-
matically controlled are the follow-
ing:
– temperature of air let into dri-
ver/passenger vents (front-seat/
back-seats);
– air distribution to vents on dri-
ver/passenger side (front-seat/
back-seats);
– fan speed (continuos variation of
air flow);
– compressor activation (to cool
air);
– air recirculation.
All these functions can be adjusted
manually, it means that one or more
system functions can be selected and
that it is possible to change their
parameters. However, in this way
the system is unable to control man-
ually selected functions which will
be changed by the system only for
safety reasons, while keeping the
required temperature.
