Obstacles placed in side areas are
detected at a distance of less than
0.6 m.
Rear sensors are automatically
switched on by removing the trailer
cable plug.FAULT INDICATIONS
The system control unit checks all
the system components every time
the ignition key is turned to MAR.
Then, the sensors and their respec-
tive electrical connections are con-
stantly monitored during system
operation.
Parking assist system faults are sig-
nalled by the lighting of symbol t
on the multifunction display, togeth-
er with message “PARKING SEN-
SOR FAULT”.
In case of fault signals, stop the
car, shut the engine off, then try to
clean the sensors, making sure that
you are not close to ultrasound-
emitting sources (e.g. truck air
brakes or pneumatic hammers). If
the cause of the operation anomaly
has been remedied, the system fully
resumes its functions and the fault
symbol on the multifunction display
goes out, together with its respective
warning message. Rear sensors are auto-
matically switched off
when the trailer’s electric
cable plug is inserted into the car
tow hitch socket.TOWING A TRAILER

If, on the contrary, the warning
lamp remains on, go to a Lancia
Dealership to have the system
checked even if the system keeps on
working. In fact, if the fault detected
by the control unit does not affect
the operation of the system, the lat-
ter keeps on working and the mal-
function is stored in the memory so
as to be detected by the Lancia
Dealership during a subsequent
check.
GENERAL NOTES
When parking your car, always pay
the greatest attention to the obsta-
cles that could be situated above or
below the sensors. In fact, objects
situated at close range in the car’s
front or rear parts could, under cer-
tain circumstances, not be detected
by the system and, therefore, dam-
age your car or be damaged them-
selves.Moreover, signals sent by the sen-
sors can be altered by damaged sen-
sors, by accumulation of dirt, snow
or ice on the sensors, or by ultra-
sound systems (e.g. truck air brakes
or pneumatic hammers) being oper-
ated nearby.INTERIOR

These rings can also be used to fas-
ten the luggage net (optional, can be
purchased at a Lancia Dealership).LUGGAGE TRANSPORT -
IMPORTANT
The car is equipped with a system
that automatically keeps headlight
height steady on different loading
conditions. The adjusting system
works properly with the maximum
allowed loads: always make sure
that the load you are carrying does
not exceed the values specified in
chapter “Technical Specifications”.
When using the boot,
make sure the load you
are carrying does not
exceed the maximum allowed
weight (see the “Technical
Specifications” chapter). Also
ensure the items in the boot are
arranged properly and fastened
with straps to the specific hooks
to prevent them being thrown for-
wards and injuring passengers
should you brake sharply.Heavy loads which are
not securely anchored
could seriously injure
passengers in the event of an
accident.
If you need to carry
petrol in a jerry-can,
always comply with the
law regulations and use a certi-
fied can, which must be properly
secured to the fastening rings. In
any case, the risk of fire in case of
accident is high.

ABS
GENERAL
If this is the first car with ABS you
drive, get familiar with it by some
preliminary “driving tests” on poor
grip roadbeds, obviously under safe-
ty conditions and in compliance with
the traffic regulations of the Country
you are driving in. Read carefully
the following instructions.
The ABS (wheel anti-locking) sys-
tem prevents wheel locking and con-
sequent slipping in all road surface
conditions. This ensures greater con-
trol, as it is possible to steering and
brake at the same time, and reduces
braking space.
If the road conditions decrease the
friction coefficient (i.e. due to the
presence of water, snow, ice, etc.) a
wheel may slip; in this case, the
wheel does not ensure correct decel-
eration or the possibility of main-
taining the running direction and
the ability to steer. Here, the ABSsystem comes into operation, elimi-
nating hydraulic pressure only from
the brake caliper of the locked wheel
and, as soon as the latter start spin-
ning again, brakes it again, thus
ensuring optimum braking and car
driveability.
EBD (ELECTRONIC BRAKE-
FORCE DISTRIBUTOR)
The car is equipped with an elec-
tronic brakeforce distributor (EBD)
which, by means of the ABS control
unit and sensors, makes it possible
to optimally distribute the braking
force between the front and rear
wheels, thus avoiding car skidding
in the most difficult situations.ABS OPERATION
The electronic control unit receives
and processes the signals from the
brake pedal and from the four sen-
sors on the wheels. It consequently
controls the hydraulic system so to
decrease, hold or increase the pres-
sure in the braking circuit of every
single wheel, and prevent locking.
The main components of the ABS
system are:
- an electronic-hydraulic control
unit, which processes the signals
from the various sensors and per-
forms the most appropriate opera-
tions by acting on the solenoid
valves
- four sensors which detect the
rotation speed of every single wheel
- a pump provided with pressure
switch, to restore brake fluid pres-
sure.
IMPORTANTA slight pulsation of
the brake pedal may be felt when
the ABS system comes into play.

247
The car is fitted with an
electronic brake force
distributor (EBD). The x
and >warning lights come on at
the same time on the multifunc-
tion display, together with mes-
sage “EBD SYSTEM FAULT”,
when the engine is running to
indicate that there is an EBD sys-
tem failure. In this case violent
braking may be accompanied by
early rear wheel locking with the
possibility of skidding. Drive the
car extremely carefully to the
nearest Lancia Dealership to
have the system checked.
If warning light x
comes on together with
message “LOW BRAKE
FLUID LEVEL”, on the multi-
function display, stop the car
immediately and contact a Lancia
Dealership. Fluid leakage will
compromise efficiency of both the
traditional brake system and the
ABS system.The system performance
in terms of active safety
must not lead the driver
to take unnecessary or unjusti-
fied risks. Always suit your dri-
ving style to the weather, visibili-
ty and traffic conditions.
Excessive use of engine
braking (gears tooshort
and limited grip) may
make the wheels slip. The ABS
will have no effect on this type of
skidding.
The maximum possible
deceleration always
depends on the available
road grip. Obviously, grip will be
considerably decreased in the
presence of snow and ice. In these
conditions, the braking space
will still be high, even with the
ABS.The coming on of the
>warning light on the
multifunction display,
together with message “ABS SYS-
TEM FAULT”, when the engine is
running, normally indicates a
fault in the ABS system. In this
case the braking system will still
be effective although without the
anti-lock device assistance. In
these conditions, EBD system
operation may also be reduced.
Drive the car extremely carefully
to the nearest Lancia Dealership
to have the ABS system checked.

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 to AVV
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.

253
Remember that until the
engine has started, the
brake booster and power
steering systems will not work
and a greater effort will therefore
be required to press the brake
pedal and turn the steering
wheel. For cars equipped with
turbosupercharger in
particular, but generally
for any kind of cars, avoid abrupt
accelerations immediately before
turning the engine off. A quick
burst on the accelerator serves
absolutely no practical purpose,
wastes fuel and may damage seri-
ously the turbosupercharger
rotor bearings.EMERGENCY START-UP
If the Lancia CODE system fails to
recognise that code transmitted by
the ignition key (symbol Ytogeth-
er with message “VEHICLE PRO-
TECTION SYSTEM FAULT” on the
multifunction display) the emer-
gency start-up can be performed by
using the CODE card code.
For the correct procedure see chap-
ter “In an emergency”.
Before opening the lug-
gage compartment bonnet
to reload the battery or to
connect an auxiliary battery,
carefully read and comply with
the instructions contained in the
paragraph “If battery is to be dis-
connected” in the chapter “In an
emergency”. Never bump start the
engine (by pushing, tow-
ing or coasting downhill)
as this could cause fuel to flow
into the catalytic exhaust system
and damage it beyond repair.
IMPORTANTIf the engine turns
off while the car is running, the
Lancia CODE symbol Yand the
message “VEHICLE PROTECTION
SYSTEM FAULT” may appear on
the multifunction display when the
engine starts again. In this case
check that the warning light switch-
es off when turning the engine off
and on again with the car stationary.
Otherwise contact aLancia
Dealership.

254
Never leave unsuper-
vised children in the car;
always remove the keys
and take them with you when you
leave the car.
If the CID device is
inside the car, the engine
can be started: therefore,
we recommend that you take the
greatest care since, in this cir-
cumstances, the engine could be
started unlawfully or by children
left unattended inside the car.PARKING
To park the car, proceed as fol-
lows:
– Stop the engine.
– Check for electric parking brake
engagement.
– Engage the 1
stgear if the car is
facing uphill or reverse if facing
downhill.
– In automatic gearbox versions
put selector to P.
– Leave the front wheels steered so
to stop the car immediately if the
parking brake is accidentally
released.
On versions equipped with sunroof
(where provided), the upper part of
the sunroof incorporates a set of
solar cells that feed the climate con-
trol system fan at first speed when
the car is parked to reduce the tem-
perature inside the passenger com-
partment.Never leave the ignition
key at MAR when the
engine is off to prevent
draining the battery.
IMPORTANT Best operation of
the fan when the car is parked is
obtained by closing completely the
windows and sunroof. Furthermore,
to check operation at first speed of
the fan, disengage air vents and set
air distribution from central dash-
board vents only before leaving the
car.
