CRUISE CONTROL
(CONSTANT SPEED
REGULATOR)
GENERAL
The electronic cruise control allows
to drive your car at the required
speed without pressing the accelera-
tor pedal. This reduces fatigue when
driving on motorways, especially
during long journeys, because the
set speed is automatically main-
tained.
IMPORTANTThe device can only
be set to speeds exceeding 30 km/h
(40 to 180 km/h for 2.4 JTD 20V
CAE version).The cruise control must
only be used when the
road and traffic condi-
tions allow to keep a constant
speed in total safety for an ade-
quately long time.CONTROLS (fig. 143)
The cruise control is operated by
means of switch A, ring Band but-
tonC(RCL).
SwitchAhas two positions:
–OFFin this position, the device is
off
–ONthis is the normal device
operating position. When the device
is ON, symbol Ülights up on the
multifunction display, together with
message “CRUISE CONTROL ON”.
RingBis used to set and maintain
the car speed or to increase or
decrease the set speed.
The device is automatically
switched off when:
– the brake pedal is pressed
– the clutch pedal is pressed
– the gear lever is unintentionally
shifted to N.
In versions with auto-
matic transmission, never
shift the lever to N when
the car is running.

Turn ring Bto position (+) to set
the speed reached or to increase the
stored speed.
Turn ring Bto position (–) to
decrease the stored speed.
The speed will be increased or
decreased by approximately 1 km/h
each time ring Bis operated. Hold
the ring turned to set the speed con-
tinuously. The new set speed will be
automatically kept.
ButtonC(RCL) allows to reset the
stored speed.
IMPORTANTTurn the ignition
key to STOPor switch AtoOFFto
delete the stored speed and switch
the system off.Storing the speed
Move switch AtoONand take the
car to the required speed normally.
Turn ring Bto (+) for at least three
seconds and release it. The car speed
will be stored and you can now
release your foot from the accelera-
tor.
The car will continue at the con-
stant speed until one of the following
events occur:
– the brake pedal is pressed
– the clutch pedal is pressed
– the automatic gear lever is unin-
tentionally shifted to N.
IMPORTANTIf required (e.g. for
overtaking) you can accelerate sim-
ply by pressing the accelerator. The
car will return to the previously set
speed when the accelerator pedal is
released.Resetting the stored speed
To reset the stored speed after
switching the device off, e.g. by
pressing the brake or the clutch ped-
als:
– accelerate progressively to reach
a speed which is close to the previ-
ously set speed
– engage the gear which was
engaged when the speed was set (4
th,
5thor 6th gear)
– press button C(RCL).
Increasing the stored speed
The stored speed can be increased
in two ways:
– by pressing the accelerator pedal
and storing the new speed (turning
ringBfor longer than three seconds)

Automatic dynamic beam adjust-
ment device
Bi-Xeno headlights require, due to
produced brilliancy, an automatic,
dynamic beam adjustment system.
This system is managed by an elec-
tronic control unit that controls the
actuators mounted on each dipped
beam headlight. Actuator control
depends on the processing of the sig-
nals from two orientation sensors.
This automatic dynamic beam
adjustment system provides the fol-
lowing advantages:
– it avoids dazzling the vehicles
coming from the opposite direction
– it stabilizes the illuminated area
so as to improve active safety.Headlight beam adjustment con-
trol unit
The control unit calculates the
instant car trim, by comparing the
signals from the orientation sensors.
A “correction” signal is sent to the
actuators to adapt light beam orien-
tation to the calculated car trim.
To avoid oscillation of the anti-
dazzling beam in case of particular
road surfaces (paved surfaces, dirt
roads, etc.) or abrupt movements of
the car caused by the driver (clutch
disengagement, gear change, etc.),
the control unit reduces the number
of corrections to be made on the
light unit.Fault indication
Anomalies in the operation of one
or several system components are
signalled by the lighting of symbol
6on the multifunction display,
together with message “HEAD-
LAMP INCLINATION ADJUST-
MENT SYSTEM FAULT”.
IMPORTANTIn case of faults,
contact a Lancia Dealership.
In case of component anomaly or
voltage drop, the system controls in
any case system operation according
to the following logic:
– faulty front sensor: trim calcula-
tion is made by replacing the voltage
value read on the faulty sensor with
a stored, fixed value
– faulty rear sensor: the system is
switched to the safety operation
mode and keeps the headlights in a
preset position of maximum lower-
ing allowed by the light beam.

HOW TO START PETROL
VERSIONS
IMPORTANTNever press the
accelerator before the engine has
started.
1) Ensure that the electric parking
brake is on (instrument panel warn-
ing light xon).
2) Ensure that electrical systems
and devices, especially high absorp-
tion ones (e.g. heated rear window),
are off.
3) On versions with manual gear-
box, set the gear lever to neutral and
press the clutch pedal fully down to
avoid the starter dragging the gears.4) On versions with electronic
automatic gearbox, ensure that the
selector is at Pand keep the brake
pedal pressed.
5) Turn the ignition key to AVV
and release it as soon as the engine
starts.
6) If the engine fails to start, return
the key to STOPand repeat the pro-
cedure.
IMPORTANTIf the engine does
not start at the first attempt, do not
keep turning the ignition key to
avoid damaging the catalyst.
Contact a Lancia Dealership.HOW TO START JTD VERSIONS
1) Ensure that the electric parking
brake is on (instrument panel warn-
ing light xon).
2) Put the gear lever to neutral.
3) Turn the ignition key to MAR.
4) Wait until the mwarning light
is off: the hotter the engine is, the
quicker this will happen.
When the engine is particularly hot
the warning light may come on so
quickly that it is impossible to notice
it.
5)Press the clutch pedal down to
the floor.
6) Turn the ignition key toAVV
immediately after the mwarning
light goes out. If you wait too long,
you will lose the benefit of the work
done by the glow plugs.

Gear selections
As soon as the traffic and road con-
ditions allow it, shift to a higher
gear. Using a lower gear to liven up
acceleration greatly increases con-
sumption. In the same way, improp-
er use of the higher gears will
increase consumption, emissions
and wear and tear on the engine.
Top speeds
Fuel consumption increases con-
siderably as speed increases. For
example, when accelerating from 90
to 120 km/h, fuel consumption
increases up to approximately
+30%. Your speed should be kept as
even as possible and superfluous
braking and acceleration avoided, as
this increases both consumption and
emissions. A “smooth” driving style
should be adopted by attempting to
anticipate manoeuvres to avoid
imminent danger, and to keep a safe
distance from the vehicle in front to
avoid braking sharplyAcceleration
Accelerating violently increasing
the revs will greatly effect consump-
tion and emissions: acceleration
should be gradual and not exceed
the maximum torque.
CONDITIONS OF USE
Cold starting
Frequent cold starting will not
enable the engine to reach optimal
running temperature. It follows,
therefore, that consumption will be
higher (from +15 to +30% in towns)
as will the production of toxic emis-
sions. Spoilers
The use of optional extras which
are not certified for specific use on
the car may reduce the aerodynamic
penetration of the car and increase
consumption.
DRIVING STYLE
Starting
Do not warm the engine when the
car is stationary or at high or low
revs: in this way the engine will
warm up gradually increasing con-
sumption and emissions. You should
drive off slowly straight away avoid-
ing high revs so that the engine will
warm up more quickly.
Unnecessary actions
Avoid revving the engine when
stopped at traffic lights or before
switching off the engine and avoid
doubling the clutch as these actions
have no purpose on modern vehicles
and serve only to increase consump-
tion and pollution.

USING THE CAR AGAIN
Before using the car again after a
prolonged period of inactivity, the
following operations are recom-
mended:
– Do not dry-dust the car body.
– Check for fluid leaks (oil, brake
and clutch fluid, engine coolant
etc.).
– Change engine oil and filter.
– Check the level of:
– brake and clutch fluid
– engine coolant.
– Check the air cleaner and change
it, if required.
– Check the tyre pressure and the
tyres for signs of damage, cuts or
cracks. If this is the case, have them
replaced.
– Check the engine belt conditions.STORING THE CAR
The following precautions should
be taken if the car will not be used
for several months:
– Park the car in covered, dry and
if possible well-ventilated premises.
– Engage a gear.
– If the car is parked on flat
ground, disengage the electric park-
ing brake as described in the rele-
vant paragraph.
– Clean and protect the painted
parts using protective wax.
– Sprinkle talcum powder on the
rubber windscreen and rear window
wiper blades and lift them off the
glass.
– Slightly open the windows.
– Inflate the tyres to 0.5 bar above
the normal specified pressure, lean
them on wood boards, if possible
and check it at intervals.– Do not switch the electronic
alarm system on.
– Remove the negative cable (-)
from the battery terminal and check
the battery charge. This check
should be performed every month if
the car is to be stored for long peri-
ods. Recharge the battery if it falls
below 12.5V.
IMPORTANTBefore opening the
luggage compartment bonnet to dis-
connect the battery, carefully read
and comply with instructions con-
tained in the paragraph “If battery is
to be disconnected” in the chapter
“In an emergency”.
– Do not drain the engine cooling
system.
– Cover the car with a cloth or per-
forated plastic sheet. Do not use
sheets of non-perforated plastic as
they do not allow moisture on the
body to evaporate.

270
– Reconnect the negative battery
terminal (-) after checking the bat-
tery charge.
IMPORTANTBefore connecting
the battery again carefully read and
comply with instructions contained
in the paragraph “If battery is to be
disconnected” in the chapter “In an
emergency”.
– With the gear lever to neutral,
start the engine and let it idle a few
minutes, pressing the clutch pedal
repeatedly.
This operation must be
carried out outdoor.
Exhaust gas contains car-
bon monoxide, an extremely
toxic gas.USEFUL
