2008 Lancia Thesis ECO mode

– 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.

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.

“Automatic parking brake” function
and the press “OK”. Deactivation of
automatic operation can be achieved
also in the following way:
– turn the key to STOP(the park-
ing brake is engaged)
– turn the key back to MAR,
depress the brake pedal and at the
same time keep button Apressed for
at least 2 seconds. Warning light x
flashes thrice to indicate the auto-
matic operation deactivation.
When the key is turned again to
STOPthe parking brake will not be
engaged. The parking brake auto-
matic operation will be automatical-
ly restored when the key is turned
again to MAR.IMPORTANTIf, after the parking
brake has been disengaged, the car
starts moving at a speed higher than
the usual manual movement, deacti-
vation of the automatic mode is
immediately cancelled and the park-
ing brake is engaged.
If, after the parking
brake has been disen-
gaged, the car starts mov-
ing at a speed higher than the
usual manual movement, deacti-
vation of the automatic mode is
immediately cancelled and the
parking brake is engaged.Proceed as follows: release the
accelerator pedal, press and keep
buttonA(fig. 133) pressed for the
whole manoeuvre: the system elec-
tronic control unit will come imme-
diately into action with alternate
braking on/off cycles on the rear
wheels (thus preventing wheel lock-
ing). Braking cycles are applied
alternately on right and left wheel to
guarantee roadholding, braking
continuity and to reduce braking
distance.
Wheel locking could take place
under the safety speed threshold
(lower than 10 km/h).
A buzzer will sound during the
whole manoeuvre to indicate that
the dynamic mode shall only be used
in an emergency, but this is also use-
ful to warn the driver if the parking
brake has been inadvertently
engaged by other passengers.
Use in an emergency
In particular cases (e.g. fault in the
whole hydraulic brake system, both
service and emergency brake), the
parking brake can be used to stop
the car running (“dynamic mode”).
