external rearview mirrors
(12 fig. 121)
Press this button to switch on the
heated rear window and external
rearview mirror demisting/defrost-
ing function. The led on the button
will come on.
The device will be automatically
switched off after ten minutes. Press
the button again or stop the engine
to switch the function off. It will not
start up automatically when the
engine is started again.
IMPORTANTDo not apply stick-
ers on the electrical filaments of the
heated rear window inside part to
prevent damage.OFF button (system off)
The switch the climate control sys-
tem off, keep pressed for at least two
seconds the fan button 14 (fig. 121)
on the front control panel or button
7 (fig. 122) on the rear control
panel; all the fan bars on the display
turn off and the message OFFwill
be displayed. The right led on the air
recirculation button will come on.
The climate control system condi-
tions when the system is off are:
– air recirculation and compressor
off button leds off;
– set temperature displays off;
– air recirculation on, thus isolating
the passenger compartment;
– climate control system compres-
sor off;
– fan off.
The heated rear window can be
switched on and off normally when
the system is off.IMPORTANTThe windows may
mist up fast when the climate con-
trol system is off and in certain envi-
ronmental conditions.
The climate control system elec-
tronic control unit stores the system
settings made before the system was
switched off and restores them as
soon as a button is pressed (with the
exception of the heated rear window
button). The function which the
button corresponds to will be
switched on, if it was off when the
system was switched off. It will be
kept if, on the other hand, it was on
when the system was switched off.
Press the AUTObutton to switch
the climate control system back on
and ensure a totally automatic con-
trol.

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.

SUPPLEMENTARY
HEATER
The supplementary heater can
work with the engine off or on and it
allows the following:
– to heat the engine coolant before
start up
– to reduce the engine warming up
time after cold starting
– to warm up the passenger com-
partment before departure
– to remove ice or condensate from
the windows.
Using the heater in winter has the
following advantages:
– to reduce engine wear
– to reduce polluting emissions
– to improve comfort during dri-
ving and stops
– to improve safety.The supplementary heater function
is useful to integrate the engine
coolant warming up during driving
in order to reach and keep the opti-
mal working temperature of the pas-
senger compartment heater in the
quickest way, especially if the cli-
mate is extremely cold.
The system is composed of:
– a heating unit
– an electric pump for the engine
coolant circulation
– an exhaust pipe with muffler
– an electric pump metering the
fuels
– a fuel delivery pipe
– a sensor for outside air tempera-
ture.The system is connected to the car
through the engine cooling system,
the fuel system and the electric sys-
tem. The coolant coming out from
the engine is conveyed to the heater
and made flow in the circuit by an
electric pump. The heater burner is
supplied with the car fuel taken
directly from the tank by means of
an electric pulse pump and then
conveyed to the appropriate system
pipe. The heater control unit sup-
plies directly both electric pumps
(fuel and coolant), activates and
checks the heater functions.
The supplementary heating system
works both with the engine running
and the engine stationary. These two
conditions determine the type of sys-
tem operating mode:
– when the engine is stationary the
supplementary heater can work in
“programmable heater” or “parked-
car heater” mode;

163
– when the engine is running the
system works only in “supplemen-
tary heater” mode.
Regardless of the operating mode,
the start up procedure for the sup-
plementary heater, once it has been
activated, is the following:
1- Fan activation for comburant
air, for at least 30 seconds, to venti-
late and oxygenate the combustion
chamber. The fan speed is progres-
sively increased until the average
operating value is reached.
2- After about 30 seconds, the
heater control unit activates the
electric pump metering the fuel and
the comburant air fan is deactivated
for at least 3 seconds, in order to
facilitate fuel burning. A spark plug
starts combustion inside the heater.
3- At this point, there is a com-
bustion stabilizing phase which lasts
around 15 seconds, during which
the fan speed is kept at average
level.4- In the following 50 seconds the
control unit makes the fan reach
nearly its highest speed.
5- Once combustion has stabilized,
the heater control unit deactivates
the plug and the fan reaches its
maximum speed.
6- From now on the plug is used
by the system as a combustion and
flame sensor.
7- Regardless of the operating
mode, the heater extinction proce-
dure is always based on the combus-
tion chamber ventilation for about
30 seconds, in order to eliminate
completely any combustion remain-
der.
IMPORTANTAfter switching the
system off, both automatically or
manually, it can be switched on
again (ON) only approx. 3 minutes
after or when the CONNECT mes-
sage “COOLING DOWN” disap-
pears from the display. IMPORTANTAlthough in a lesser
quantity the heater burns fuel as the
engine. Therefore, to prevent poi-
soning and suffocation the supple-
mentary heater shall never be turned
on, even temporarily, in confined
areas like garages and workshops
not equipped with exhaust fans.
IMPORTANTThe heater must
always be turned off during refu-
elling and at filling stations to pre-
vent the risk of explosions.
IMPORTANTDo not park the car
over flammable materials like paper,
grass or dry leaves: risk of fire.
OPERATION WITH ENGINE
STATIONARY
“Programmable heater” mode
With this operating mode, the sys-
tem heats the engine coolant and the
passenger compartment before
starting the engine, it keeps air recir-
culation closed and activates air dis-
tribution to the windscreen and the
floor by operating the passenger
compartment fan.

164
This function can be activated with
the CONNECT (from the main
SETUP screen) or with the remote
control.
The system works with this mode on
if the following conditions are present
– outside temperature lower than 20
°C
– coolant temperature lower than 50
°C
– ignition key at STOPor removed
– car battery charged
– fuel not in reserve.
When this mode is on, the heater is
deactivated when one of the following
conditions occur:
– end of planned working time
– OFF signal from the remote con-
trol
– manual shutdown by the user
through CONNECT– ignition key at MAR
– partial battery rundown
– fuel in reserve
– malfunction detected by the heater
control unit.
Timed heater activation/
deactivation through CONNECT
Timed heater activation and deacti-
vation can be set through the CON-
NECT. Select and confirm “Heater”
on the main SETUP screen to display
the parked-car heater settings.
Settings available are the following:
– Operate now
– Timer 1
– Timer 2.
To activate/deactivate the required
function, select and confirm it with
the CONNECT right knob.“Operate now”
The option “Operate now” enables
to warm the passenger compartment
with the engine stopped and warm
and the ignition key to MAR, using
the engine coolant, heater coolant cir-
culation pump, automatic air distrib-
ution control (if not set manually) and
closing air recirculation. The timer
cannot be programmed when this
function is on.
To guarantee the required comfort,
this function shall be mainly activated
when coolant is hot enough. When
coolant temperature is lower than 50
°C the control unit starts the heater,
and when temperature is over 70 °C,
the control unit turns the heater off
and lets only the coolant circulation
pump keep on working.

165
The “parked-car heater” mode is
automatically deactivated when one
of the following conditions takes
place:
– engine started
– limit time (around 30 minutes) of
heater and/or coolant pump func-
tioning overcome
– turn off requested by the user
through the CONNECT
– malfunction detected by the heater
control unit
– partial battery run-down or alter-
nator fault.
“Timer 1” and “Timer 2”
The “Timer” options shall be used
to programme two heater daily cycles;
for each cycle enter the time of acti-
vation and the length of operation
both with 5 minute intervals.
Each cycle cannot last more than 60
minutes. The default operation is 15
minutes. The timer works regardless
of the ignition key position.During heater operation, messages
referred to the following conditions
are shown on CONNECT display:
– fuel level in reserve (continue any-
way?)
– fuel level in reserve. Parked-car
heater has been switched off
– parked-car heater not operating
because of cooling down
– parked-car heater not operating
because external temperature is
higher than 20 °C
– parked-car heater not operating
because motor is on
– parked-car heater has been
switched off because of low voltage.IMPORTANTFor safety reasons,
the timer must be programmed/con-
firmed at any activation and con-
firmed not later than 24 hours since
programming. In addition, the user
must confirm every time the timer ac-
tivation. The timer does not automat-
ically correct standard time.
The timer can be in one of the fol-
lowing conditions:
– off: in this condition the timer is
programmable and parameters can be
loaded or adjusted. Loaded parame-
ters should be valued and approved
by CONNECT
– on: activated parameters approved
by CONNECT are stored in the mem-
ory. The user confirms the set cycle
waiting for the programmed activa-
tion moment which is indicated on the
CONNECT display
– active: the heater is working in
“programmable heater” mode con-
trolled by the timer present on the
CONNECT display. When the timer
is activated, the CONNECT records
the system conditions

166
– stationary: with the “programma-
ble heater” mode controlled by the
timer, the system conditions are con-
trolled by CONNECT.
The timer is automatically deacti-
vated if:
– the “programmable heater” mode
function is stopped by CONNECT if,
at the timer start, the “programmable
heater” mode is activated with the re-
mote control
– if the user manually activates the
heater during the timer operation
– if the timer is activated within 3
minutes after the previous heater
shutdown
– if the user manually deactivates
the timer– if the fuel level in the tank is low
when the timer is activated. This con-
dition is indicated with a message
coming from the system and the user
must confirm activation. If the user
does not confirm activation, the timer
is deactivated. The fuel level is indi-
cated by the CONNECT; if this infor-
mation is not available, it is taken into
consideration the last record before
stopping the engine
– if the timer is activated when the
heater operated by the remote control
is activated.
IMPORTANTIf the heater is in
prompt operating mode, the timer is
automatically stopped at the moment
of activation. Parameters set with the
timer are stored in the memory. If the
timer has been deactivated or
stopped, it should be manually reac-
tivated by the user.HEATER ACTIVATION/
DEACTIVATION WITH THE
REMOTE CONTROL (fig. 123)
Activation/deactivation of the heater
can be operated with remote control
A.
The activation signal is issued by the
remote control with a range of around
600 meters and picked up by a spe-
cific antenna placed on the car, then
it is transmitted to the supplementary
heater receiver and sent to CON-
NECT.
IMPORTANTThe maximum re-
mote control range is reached on open
land, while it is reduced in the pres-
ence of buildings.

167
This control is accepted by CON-
NECT only if:
– outside temperature lower than 20
°C
– coolant temperature lower than 50
°C
– the ignition key is at STOPor re-
moved
– car battery charged
– sufficient fuel level
– the timer is deactivated.
Switching the heater on
To switch the heater on, press the
remote control button ONfor 1 or 2
seconds, while keeping the antenna in
vertical position; the positive or un-
successful activation is indicated by
the remote control red led Bin the fol-
lowing way:
– the led turns on for about 2 sec-
onds = the signal has been correctly
received and the heater has been ac-
tivated– the led flashes for about 2 seconds
= the signal has not been received.
In the latter case you are advised to
move before trying to activate it by
pressing again the ONbutton.
After the confirmation activation,
the led Bwill flash every 2 seconds for
the whole operation cycle duration.
IMPORTANTIf led Bturns on with
green colour, press twice both remote
control buttons ONand OFFwithin 1
second to set the red colour.
Activation length
When pressing the remote control
button ONthe last recorded activa-
tion length is always activated.
To see the recorded length, press at
the same time for three consecutive
times within 1 second, the remote
control buttons ONand OFF, count
the number of flashes of led Bthen
compare them to those shown in the
table below, including also the first
flash appearing the third time you
press the buttons. Default activation length is 30 min-
utes but it can be changed through
the following procedure:
– press at the same time for three
consecutive times within 1 second, the
remote control buttons ONand OFF
– count the number of flashes of led
Bincluding also the first flash ap-
pearing the third time you press but-
tons ONand OFF
– press OFFto set the length suc-
cessive to the set one (press OFFfor
several times to set the required
length in sequence)
– wait for about 10 seconds for timer
storing.

168
- the led comes on for about 2 sec-
onds = the signal has been received
correctly and the heater has been de-
activated
- the led flashes for about 2 seconds
= the signal has not been received.
In the latter case you are advised to
move before trying to deactivate it by
pressing again the OFFbutton.Checking and replacing the
batteries
To check the battery charge, press
ONor OFF: if after about 5 seconds
led Bcomes on with orange colour it
means that the batteries are nearly
down and that they shall be replaced.
The batteries must be replaced with
new ones of the same type, available
at the usual sellers.
Replacing the batteries
Keep the ONand OFFbuttons
pressed for about 10 seconds, until led
Bturns off, to reset the 30 minutes
standard operation length.
Switching the heater off
To turn the heater off, press the re-
mote control button OFFfor 1 or 2
seconds, while keeping the antenna in
vertical position; the positive or un-
successful deactivation is indicate by
the remote control red led Bin the fol-
lowing way:Used batteries pollute the
environment. Dispose of
them in the special con-
tainers as specified by current leg-
islation. Keep batteries away from
open flames and high tempera-
tures. Keep away from children.

OPERATION
WITH ENGINE RUNNING
“Supplementary heater” mode
This operating mode integrates the
engine coolant warming up, immedi-
ately after start up or during driving,
to reach and keep the optimal work-
ing temperature of the engine and the
passenger compartment heater in the
quickest way.
This mode is activated automatically
by the climate control unit when the
following conditions occur at the same
time:
– ignition key at MAR
– engine running– coolant temperature lower than 30
°C
– the climate control unit detects
(according to sensor detected temper-
atures) that fast passenger compart-
ment warming is required.
This mode is automatically deacti-
vated when one of the following con-
ditions occurs:
– coolant temperature higher than
70 °C
– the heater control unit detects a
fault in the supplementary heater
– engine off. The batteries must be replaced with
new ones of the same type, available
at the usual sellers.
To replace batteries:
– remove the remote control cover
by pushing it in the arrow direction
indicated on the cover
– remove exhausted batteries and
take note of their position
– fit the new batteries with pole (+)
towards the remote control antenna
– fit down the cover.
Request for additional remote
controls
The heater receiver will acknowl-
edge up to three remote controls. To
order new remote controls, or to re-
place the original one, contact a Lan-
cia Dealership.
