SUPPLEMENTARY
HEATER
(where provided)
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.

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.

FUEL CUT-OFF SWITCH AND
CIRCUIT BREAKER
The car is fitted with two safety
switches that come into operation in
the case of an accident to block fuel
supply and power, thereby stopping
the engine and the car electric utili-
ties. It also prevents fuel spilling if the
lines are broken in the accident or
sparks and flashover due to electric
component damages.
After the crash, remember to turn
the ignition key to STOPto prevent
the battery running down.

174
Lift cover Aset at the driver's left
and press button Bto reset the fuel
cut-off switch.
Resetting the circuit breaker
Before resetting the cir-
cuit breaker, carefully
check for any fuel leaks or
damages to the car electric devices
(e.g.: headlights).Circuit breaker is located on the left
side of the boot, inside a box directly
set and connected to the battery pos-
itive terminal.
To reach the circuit breaker:
1) Open the tailgate.
2) Loosen knob A(fig. 130) and re-
move the battery cover B.
3) Press tabs A(fig. 131) and re-
move cover B.
4) Press button A(fig. 132) to reset
the circuit breaker.Initialising the control units of
the door locks, air conditioner
and ESP system
After resetting the circuit breaker, to
restore correct door locking, air con-
ditioning and ESP system, perform
the following operations:
1) Close the doors and the tailgate,
fit the key into the lock of one of the
front doors and perform a door cen-
tralised opening/closing cycle.
2) Start the engine and turn on the
compressor of the conditioner, setting
a lower temperature value than that
of the environment and check
whether the led on the disconnection
push button of the conditioner com-
pressoròis lit.
3) Turn the steering wheel one
fourth turn at least (the car can be at
standstill but the engine shall be run-
ning) and start running the car for a
few metres in a straight line until the
ESP warning light
áis off.

ELECTRIC PARKING BRAKE
(EPB) (fig. 133)
The car is fitted with the EPB
(Electric Parking Brake) that cuts in
when switching the engine off and
will cut out when starting the engine
and pressing the accelerator pedal
(for manual gearbox versions when
releasing the clutch pedal at the
same time). The EPB can also be
disengaged manually by pressing
buttonAset on the central console
with engine running or ignition key
toMAR.
After disengaging the EPB manual-
ly, when opening the driver’s door
the EPB will re-engage automatical-
ly, press button Aagain to disengage
it.The button shape is rather large so
the brake can be engaged rapidly,
even by the passenger, in case of
emergency.
The advantages of this system, com-
pared to the usual lever, are several:
– no effort should be made to
engage and disengage the parking
brake
– the parking brake efficiency is
always at top level in any using con-
dition, contrary to the lever which
guarantees the car complete stop only
when fully lifted
– the EPB is controlled by electric
wires, therefore all problems regard-
ing transmission cables, such as
adjustments, freezing or tears, no
longer exist
– improved safety as a result of the
sophisticated electronic control sys-
tem, similar to the ABS one, prevent-
ing wheels from blocking if the park-
ing brake is engaged during driving
– improved safety when the car is
stationary and children are left
inside the car; in this case the brake
cannot be disengaged if the ignition
key is at STOPor removed– it has automatic functions that
other systems lack.
When the parking brake is engaged
and the ignition key is at MAR, the
instrument panel warning light x
turns on.
This warning light turns on when
the parking brake reaches its highest
working level, and it turns off when
the brake is disengaged and com-
pletely released. Unlike usual park-
ing brakes, whose warning light
turns on even when the lever is lift-
ed a little bit, the EPB system warn-
ing light turns on only when the car
has come to a complete stop.
When the brake is engaged, a typi-
cal noise can be heard by the driver;
the parking brake is completely
engaged or disengaged when the
operating noise stops.
fig. 133
L0A0197b
When engaging the park-
ing brake keep the brake
pedal always depressed.
