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.

ACTIVE CARBON
DUST/POLLEN FILTER
The filter has the specific capacity
of combining a mechanical air
cleaning action and an electrostatic
effect so that the air let into the pas-
senger compartment is purified from
particles such as dust, pollen, etc.
In addition to this function, the fil-
ter efficaciously reduces the concen-
tration of pollutants thanks to a
layer of active carbon inside the fil-
ter.
The filtering action is carried out
on the air let in from outside (recir-
culation off).
Have the filter checked at least
once a year at a Lancia
Dealership, ideally at the begin-
ning of the summer.The efficacy of the cli-
mate control system may
be considerably reduced
if the filter is not replaced.Fan actuation is automatic and air
distribution corresponds to the latest
setting made before switching the
car off.
This function is useful especially on
summer days since it greatly reduces
the temperature inside the passenger
compartment as well as the duration
of the cooling cycle after car start-
up, thus avoiding the accumulation
of warm air in the air conditioning
unit lines.
IMPORTANTBest operation of
the fan when the car is parked is
obtained by closing completely the
windows and sunroof. Furthermore,
to check operation at first speed of
the fan, disengage air vents and set
air distribution from central dash-
board vents only before leaving the
car.You should have the filter checked
and if required replaced more fre-
quently if the car is mainly used in
polluted or dusty areas.
VENTILATION DURING A STOP
In versions with sunroof, the roof
top features 21 photovoltaic cells
supplying a maximum power of 24
W to supply the climate control sys-
tem fan when the car is parked with
the roof closed or horizontally pivot-
ing.

USING THE CAR AGAIN
Before using the car again after a
prolonged period of inactivity, the
following operations are recom-
mended:
– Do not dry-dust the car body.
– Check for fluid leaks (oil, brake
and clutch fluid, engine coolant
etc.).
– Change engine oil and filter.
– Check the level of:
– brake and clutch fluid
– engine coolant.
– Check the air cleaner and change
it, if required.
– Check the tyre pressure and the
tyres for signs of damage, cuts or
cracks. If this is the case, have them
replaced.
– Check the engine belt conditions.STORING THE CAR
The following precautions should
be taken if the car will not be used
for several months:
– Park the car in covered, dry and
if possible well-ventilated premises.
– Engage a gear.
– If the car is parked on flat
ground, disengage the electric park-
ing brake as described in the rele-
vant paragraph.
– Clean and protect the painted
parts using protective wax.
– Sprinkle talcum powder on the
rubber windscreen and rear window
wiper blades and lift them off the
glass.
– Slightly open the windows.
– Inflate the tyres to 0.5 bar above
the normal specified pressure, lean
them on wood boards, if possible
and check it at intervals.– Do not switch the electronic
alarm system on.
– Remove the negative cable (-)
from the battery terminal and check
the battery charge. This check
should be performed every month if
the car is to be stored for long peri-
ods. Recharge the battery if it falls
below 12.5V.
IMPORTANTBefore opening the
luggage compartment bonnet to dis-
connect the battery, carefully read
and comply with instructions con-
tained in the paragraph “If battery is
to be disconnected” in the chapter
“In an emergency”.
– Do not drain the engine cooling
system.
– Cover the car with a cloth or per-
forated plastic sheet. Do not use
sheets of non-perforated plastic as
they do not allow moisture on the
body to evaporate.

IMPORTANT - Diesel filter
The different grades of purity in
diesel fuel normally available might
make it necessary to replace the fil-
ter more frequently than indicated
in the Service Schedule. If the engine
misfires it shows the filter needs
changing.IMPORTANT - Dust/pollen filter
If the car is often used in dusty or
extremely polluted environments,
you should change the filter element
more frequently. It should be
changed especially if the amount of
air introduced into the passenger
compartment is reduced.IMPORTANT - Battery
The charge in your battery should
be checked, where possible at the
start of the winter, to limit the risk
of the battery electrolyte freezing.
This check should be carried out
more frequently if the car is mainly
used for short trips or if it is fitted
with accessories that permanently
take in electricity even when the
ignition key is removed, especially in
the case of after market accessories.
If the car is used in very hot cli-
mates or particularly demanding
conditions check the battery elec-
trolyte more frequently than shown
in the “Service Schedule” in the
“Car maintenance” chapter.

325
AIR CLEANER
The air cleaner is connected to the
air temperature and intake sensors
which send the electrical signals
required for the correct operation of
the injection and ignition system to
the control unit.
Consequently, the cleaner must
always be in perfect conditions to
ensure correct operation of the
engine and in order to contain con-
sumption and exhaust emissions.Replace the air cleaner
more frequently than
shown in the Service
Schedule if the car is used on
dusty roads.
The cleaner can be dam-
aged if it is cleaned and
consequently the engine
can be damaged.
DIESEL FILTER
(JTD versions)
DRAINING THE
CONDENSE
The presence of water in
the fuel feed circuit can
severely damage the
injection system and make the
engine misfire. Go to a Lancia
Dealership as soon as possible
when the cwarning light comes
on together with message
“WATER IN DIESEL FILTER” on
the multifunction display to have
the bleeding operation carried
out.
The air cleaner replace-
ment procedure is pro-
vided for indicative pur-
poses only. Have the operation
carried out at a Lancia
Dealership. Car safety can be
compromised if the cleaner
replacement procedure herein
described is not carried out cor-
rectly.

326
Batteries contain sub-
stances that are very
harmful for the environ-
ment. You are advised to have the
battery changed at a Lancia
Dealership. It is properly
equipped for disposing of used
batteries in an environmentally-
friendly way that complies with
the law.
With the battery flat, or
after the interruption of
one of the protection
fuses, or if you want to disconnect
a loaded battery (e.g. for a car
stop period), before opening the
luggage compartment bonnet
carefully read and comply with
the instructions contained in the
paragraph “If battery is to be dis-
connected” in the chapter “In an
emergency”.
DUST/POLLEN
FILTER
This filter has a mechanical/elec-
trostatic air filtering action, provid-
ed that windows and doors are
closed.
Have the dust/pollen filter checked
once a year at a Lancia Dealership,
preferably at the onset of summer.
If the car is often used in dusty or
extremely polluted environments,
have the filter replaced more fre-
quently than specified in the Service
Schedule.
IMPORTANTFailure to replace
this filter can significantly reduce
climate control system effectiveness.
BATTERY
The battery is of the “Low
Maintenance” type and is fitted with
an indicator A(fig. 18) for checking
the electrolyte level and battery
charge.
Under normal condition of use top-
ping up the electrolyte with distilled
water is therefore not required. A
periodical check is however neces-
sary to make sure it is in efficient
conditions through the indicator on
the battery cover which should be
dark in colour with a green central
area.If the indicator is a bright colour,
or dark without the green central
area, contact a Lancia Dealership.
