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

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.

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.

252
IMPORTANTEnergy-absorbing
devices (climate control system,
heated rear window etc.) are auto-
matically disconnected at starting.
If the engine does not start at the
first attempt, return the ignition key
to STOPbefore trying to start the
engine again.
If starting is particularly diffi-
cult,(with the Lancia CODE system
working properly) do not keep try-
ing too many times.
Use an auxiliary battery only if the
battery has insufficient charge.
Never use a battery charger to start
the engine. ENGINE WARMING UP
– Begin to move forward slowly let-
ting the engine turn at medium revs.
Do not accelerate abruptly.
– Do not push the engine to its limit
for the first few kilometers. You are
recommended to wait until the
coolant temperature has reached 50
to 60 °C.STOPPING THE ENGINE
– Release the accelerator pedal and
wait until the engine is idling.
– Turn the ignition key to STOP
and turn the engine off. For versions
with electronic automatic gearbox,
put the selector to Pbefore turning
the engine off.
IMPORTANTAfter a taxing drive
you should allow the engine to
“catch its breath” before turning it
off by letting it idle to allow the tem-
perature in the engine compartment
to fall.

SAFE DRIVING
In designing THESIS, LANCIA has
made every effort to come up with a
car able to provide driver and pas-
senger with top-class levels of safety.
Nevertheless it is always the behav-
iour of the person at the wheel that
determines road safety.
Below you will find some simple
tips to help you travel in safety
under different conditions. You will
no doubt be familiar with many of
them already, but it will be useful to
read them all carefully.
BEFORE GETTING BEHIND
THE WHEEL
– Make sure all lights, including
the headlights, are working proper-
ly.
– Adjust the position of the seats,
steering wheel, driving and door
mirrors properly for the best driving
position.
– Carefully adjust the head
restraints so that the back of the
head and not the nape of the neck is
supported. Make sure that nothing (mats etc.)
gets in the way of the pedals when
they are pushed down.
– Make sure that any child
restraint systems (child seats, carri-
ers etc.) are properly fixed on the
rear seat.
– Place any objects in the boot in
such a way that they cannot be
thrown forwards in the event of an
accident.
– Do not eat a heavy meal before
travelling. Light eating will help
keep your reflexes prompt. Above
all, do not have anything alcoholic to
drink.
Periodically, remember to check:
– tyre pressure and conditions;
– engine oil level;
– coolant level and cooling system
conditions;
– brake fluid level;
– power steering fluid level;
– windscreen washer fluid level. WHEN TRAVELLING
– The first rule of safe driving is
prudence.
– Prudence also means putting
yourself into a position where you
can predict wrong or imprudent
behaviour from other drivers.
– Stick closely to the rules of the
road in the particular country where
the vehicle is being driven and,
above all, do not exceed speed limits.
– Ensure that, besides yourself, all
the other passengers in the vehicle
have their seat belts fastened, that
children are sitting in the appropri-
ate child seats and any animals in
the car are placed in suitable com-
partments.
– You should be physically fit and
mentally alert before setting out on
long journeys.
