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.

263
Ignoring the above rules
may lead to fire. When functioning nor-
mally, the catalytic con-
verter reaches high tem-
peratures. For this reason, do not
park the car over inflammable
material (grass, dry leaves, pine
needles, etc.): fire hazard.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda
sensor and exhaust pipe. Do not install other heat
shields and do not remove
those already fitted to the
catalytic converter and exhaust
pipe.Never run the engine with the
spark plugs disconnected even for
testing purposes. Do not warm up
the engine by letting it idle for a
while before moving off unless the
outside temperature is very low and,
even in this case, only do so for less
than 30 seconds.
If you have trouble starting, do not
keep turning the ignition key for
long periods. Be especially careful to
avoid bump starting the car by
pushing, towing or rolling downhill:
these are all manoeuvres that can
damage the catalytic exhaust sys-
tem. Use an auxiliary battery for
start-ups only.
If the engine begins to “lose its
smoothness” when travelling, con-
tinue your journey but reduce the
demands you are making on the
engine and have the car seen at a
Lancia Dealershipas soon as you
can.
When the instrument panel fuel
reserve warning light comes on, fill
up as soon as possible. A low level of
fuel can cause an uneven supply of
fuel to the engine with the inevitable
increase in the temperature of the
exhaust gas and serious damages to
the catalytic converter.

TOWING A
TRAILER
GENERAL NOTES
The car must be fitted with a
homologated tow hitch and suitable
electrical system for towing a cara-
van or a trailer. Have the tow hitch
fitted by an expert who will issue
specific documentation for use on
roads.
Fit special and/or additional
rearview mirrors in accordance with
the highway code.
Remember that towing a trailer
makes it harder for the car to climb
the maximum gradients specified,
increases braking and overtaking
distance, proportionally to the over-
all weight of the trailer.Engage a low gear when driving
downhill rather than constantly
braking.
The weight the trailer exerts on the
car’s tow hitch coupling reduces the
car’s loading capacity by the same
amount. In order to be sure you are
not exceeding the maximum towing
weight (as specified in the registra-
tion book), you have to take into
account the trailer’s fully laden
weight, including accessories and
personal luggage.
Do not exceed the speed limits for
towing a trailer in the country you
are driving in. In any case, do not
exceed the top speed of 100 km/h.
Trailer electrical connection shall
only be performed with ignition key
atSTOPor removed.
When trailer electrical connection
is on and you switch on the rear fog
lights, only the trailer rear fog lights
will come on.The ABS system will not
control the trailing brak-
ing system. Great care
should therefore be taken when
driving on slippery road surfaces.
Under no circumstances
modify the car’s braking
system for trailer braking
control. The trailer’s braking sys-
tem must be completely indepen-
dent of the car’s hydraulic sys-
tem.
The rear parking sensors
are automatically deacti-
vated when the plug of the
trailer’s electrical cable is insert-
ed in the car’s tow hitch socket.
The rear sensors activate auto-
matically when the trailer’s plug is
disconnected.

AIR CLEANER
The air cleaner is connected to the
air temperature and intake sensors
which send the electrical signals
required for the correct operation of
the injection and ignition system to
the control unit.
Consequently, the cleaner must
always be in perfect conditions to
ensure correct operation of the
engine and in order to contain con-
sumption and exhaust emissions.Replace the air cleaner
more frequently than
shown in the Service
Schedule if the car is used on
dusty roads.
The cleaner can be dam-
aged if it is cleaned and
consequently the engine
can be damaged.
DIESEL FILTER
(JTD versions)
DRAINING THE
CONDENSE
The presence of water in
the fuel feed circuit can
severely damage the
injection system and make the
engine misfire. Go to a Lancia
Dealership as soon as possible
when the cwarning light comes
on together with message
“WATER IN DIESEL FILTER” on
the multifunction display to have
the bleeding operation carried
out.
The air cleaner replace-
ment procedure is pro-
vided for indicative pur-
poses only. Have the operation
carried out at a Lancia
Dealership. Car safety can be
compromised if the cleaner
replacement procedure herein
described is not carried out cor-
rectly.

337
Detergents pollute water.
For this reason the car
must be washed in an
area equipped for the collection
and purification of the liquids
used while washing.TIPS FOR KEEPING THE BODY
IN GOOD CONDITIONS
Paintwork
The paintwork is not only to make
your car look attractive but also to
protect the steel.
If the paint is scuffed or scratched
deeply you are therefore advised to
touch up as necessary to prevent rust
from forming.
Only use genuine products when
touching up the paintwork (see
“Bodywork paint identification
plate” in chapter “Technical
Specifications”).
Ordinary maintenance of the
paintwork means washing it. The
frequency you should do this
depends on the conditions and the
environment the car is driven in. For
example, you should wash your car
more often if it is driven in areas
with a high level of air pollution or
on road sprinkled with saltwash.Before leaving your car
into the automatic car-
wash tunnel, disengage
the parking brake following the
instructions given in the relevant
paragraph, and leave the Keyless
System CID (where fitted) in the
car to prevent automatic steering
locking.Before cleaning the
windscreen (e.g. at filling
stations), make sure to
have deactivated the rain sensor
and turned the ignition key to
STOP. Deactivate the rain sensor
also when washing your car man-
ually or at automatic carwash.
