For an emergency engine start up
proceed as follows:
– Lay the CID device into the emer-
gency seat A(fig. 21)
– Push on the clutch pedal (manual
gearbox versions) or on the brake
pedal (automatic gearbox versions)
– To turn on the instrument panel,
turn knob A(fig. 22) to position
MAR.
To start engine, turn the knob A
(fig. 22) to positionAVV, and release
as soon as the engine is started.
When the car is running, the
engine gets going even if the CID
device has been removed from the
“garage” position. In any case, the
CID device will have to be put back
to the “garage” position for subse-
quent start-up.
IMPORTANTSet free from any
object compartment A(fig. 21),
before starting the emergency engine
start-up procedure.
IMPORTANTRemember to carry
about with you the CID device
before moving away from the car. KNOB FOR ACTUATING
INSTRUMENT PANEL
AND ENGINE START-UP
The car is fitted with a switch con-
trolled by knob A(fig. 22), enabling
to actuate STOP, MARand AVV
starter motor switch functions.
IMPORTANTKnob rotation is
enabled by the presence of the CID
device in the car and by the pressing
of the clutch pedal (or the brake pedal
for cars with automatic transmission).
STOP position
This position of the switch knob
corresponds to: engine off and steer-
ing column lock on. Certain electri-
cal devices (e.g. CONNECT) can be
operated.MAR position
This is the running position and
corresponds to: instrument panel on
and steering column lock off. All the
electrical devices can be operated.
AVV position
This is the position for engine
start-up: release the knob as soon as
the engine has started. The engine
can be started only when the CID
device is inside the car.
IMPORTANTSystem checks for
the presence of a CID device inside
the passenger compartment, when-
ever a door or the luggage compart-
ment are closed, while the instru-
ment panel is turned on or the
engine is running. If the CID device
is not identified, e.g. because the
CID owner leaves the car, the dis-
play on the instrument panel will
display the message: “ELECTRON-
IC KEY NO LONGER PRESENT IN
THE CAR – ENGINE CANNOT BE
RESTARTED”. The engine will
keep on running and instrument
panel will remain on, until the suc-

In these conditions it is possible to
continue driving without however
demanding heavy effort or high
speeds. Prolonged use of the car with
the warning light on may cause
damages. Contact a Lancia

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;

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-
pressor òis 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.

R - Reverse
Shift the lever to Rwith the car
stationary, the engine running idle
and the brake pedal pressed.
When the lever is at Rbackup
lights turn on and a buzzer will
sound for about 4 seconds to warn
other people that reversing is in
progress.
IMPORTANTEven with the lever
in position R, the reverse gear can-
not be engaged if the car speed is
higher than the established value.
When the speed is reduced, the
reverse gear can be engaged and it
remains engaged even if the car
speed overcomes that limit.N - Neutral
This is the position to be used when
the car must be pushed or towed.
D - Forward gear (automatic)
This is the position to be used when
all automatic gearbox functions are
required.
The electronic control unit controls
that the five gears are engaged auto-
matically according to car speed,
engine rpm, accelerator pedal posi-
tion and pressing speed, together
with the main driving conditions
such as hills, slopes, curves and
braking.
Indeed, the electronic automatic
gearbox is able to choose, according
to the type of driving adopted by the
driver, different programmes subdi-
vided into comfortable driving,
economy driving and sporty driving,
with shift points ranging between
low and high. Before leaving the car,
check that the electric
parking brake (EPB) is
on. Shift the lever to position P
even when the car is left with the
engine running.
In case of emergency (failures, flat
battery, etc.), it is possible to shift
the lever from position Pto N, D or
Rby pressing lever A(fig. 141) set
under the gear lever mask. To reach
the lever, remove the press-fit odd-
ment compartment shelf Bin front
of the gearshift lever.
