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.

SAFE DRIVING
In designing THESIS, LANCIA has
made every effort to come up with a
car able to provide driver and pas-
senger with top-class levels of safety.
Nevertheless it is always the behav-
iour of the person at the wheel that
determines road safety.
Below you will find some simple
tips to help you travel in safety
under different conditions. You will
no doubt be familiar with many of
them already, but it will be useful to
read them all carefully.
BEFORE GETTING BEHIND
THE WHEEL
– Make sure all lights, including
the headlights, are working proper-
ly.
– Adjust the position of the seats,
steering wheel, driving and door
mirrors properly for the best driving
position.
– Carefully adjust the head
restraints so that the back of the
head and not the nape of the neck is
supported. Make sure that nothing (mats etc.)
gets in the way of the pedals when
they are pushed down.
– Make sure that any child
restraint systems (child seats, carri-
ers etc.) are properly fixed on the
rear seat.
– Place any objects in the boot in
such a way that they cannot be
thrown forwards in the event of an
accident.
– Do not eat a heavy meal before
travelling. Light eating will help
keep your reflexes prompt. Above
all, do not have anything alcoholic to
drink.
Periodically, remember to check:
– tyre pressure and conditions;
– engine oil level;
– coolant level and cooling system
conditions;
– brake fluid level;
– power steering fluid level;
– windscreen washer fluid level. WHEN TRAVELLING
– The first rule of safe driving is
prudence.
– Prudence also means putting
yourself into a position where you
can predict wrong or imprudent
behaviour from other drivers.
– Stick closely to the rules of the
road in the particular country where
the vehicle is being driven and,
above all, do not exceed speed limits.
– Ensure that, besides yourself, all
the other passengers in the vehicle
have their seat belts fastened, that
children are sitting in the appropri-
ate child seats and any animals in
the car are placed in suitable com-
partments.
– You should be physically fit and
mentally alert before setting out on
long journeys.

CONTAINING RUNNING COSTS AND
POLLUTION
Some suggestions which may help
you to keep the running costs of the
car down and lower the amount of
toxic emissions released into the
atmosphere are given below.
GENERAL CONSIDERATIONS
Car maintenance
The overall state of the car is an
important factor which has a
marked influence over fuel con-
sumption and driving comfort and
on the life span of your car. For this
reason care should be taken to main-
tain your car by carrying out the
necessary checks and regulations in
accordance with the specifications
given in the “Service Schedule” (see
sections: spark plugs, air cleaners,
timing...).Tyres
Tyre pressure should be checked at
least once every four weeks: if the
pressure is too low fuel consumption
increases as the resistance to the
rolling movement of the tyre is
greater. In this state, tyre wear is
increased and handling suffers,
which will effect safety.
Unnecessary loads
Do not travel with too much load in
the boot. The weight of the car (in
town traffic above all), and its trim
greatly effect consumption and sta-
bility.Roof rack/ski rack
Remove the roof or ski racks from
the car as soon as they are no longer
needed. These accessories reduce the
aerodynamic penetration of the car
and will increase consumption.
When transporting particularly
large objects, use a trailer, where
possible.
Electrical devices
Use electrical devices for the neces-
sary time only. The heated rear win-
dow, fog lights, windscreen wipers,
heater fan require large amounts of
electricity and increasing the request
for power will also increase fuel con-
sumption (up to +25% when driving
in towns).
Climate control system
The climate control system is an
additional load which greatly effects
the engine leading to higher con-
sumption (up to +20% in average).
When the temperature outside
allows, use the air vents where pos-
sible.

267
WINTER TYRES
These tyres have been specifically
designed for use on snow and ice
and should be fitted in place of the
existing tyres.
Use only the homologated tyres
listed in log book.
Lancia Dealershipswill be glad
to provide advice on the most suit-
able type of tyres according to your
needs.
For information on the tyres to be
fitted, inflation pressure and winter
tyre specifications, follow the pre-
scriptions given in “Technical speci-
fications”.
The performance of winter tyres is
greatly reduced when the tread
depth is less than 4mm. In this situ-
ation it would be safer to have them
replaced.Due to winter tyre features, under
normal conditions of use or on long
motorway journeys, the perfor-
mance of these tyres is lower than
that of standard tyres.
The use of these tyres should there-
fore be limited to the conditions for
which they were designed and certi-
fied.
IMPORTANT When using winter
tyres with a maximum speed index
below the one that can be reached
by the car (increased by 5%), place
a suitable notice in the passenger
compartment to inform the driver of
the top speed at which the winter
tyre can run (as per EC Directive).All four tyres should be the same
(brand and track), to ensure greater
safety when driving, braking and
cornering.
Remember that it is inappropriate
to change the direction of rotation of
tyres.
The maximum speed for winter
tyres with “Q” marking is 160
km/h, with “T” marking is 190
km/h, whereas with “H” marking is
210 km/h. Always respect the high-
way code speed limit.

269
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.
IMPORTANT Before 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.

274
Signal the presence of
the stopped car according
to the laws in force: haz-
ard lights, reflecting triangle, etc.
Passengers should get out of the
car and stay clear from oncoming
traffic while the wheel is being
changed.
IF A TYRE
IS PUNCTURED
Follow the instructions on this and
the following pages to use the jack
and the spare wheel correctly.If the wheel is being
changed on a steep or
badly surfaced road,
place wedges or other suitable
material under the wheels to stop
the car from moving.
Have the punctured tyre
repaired and fitted back as soon
as possible. Do not lubricate the
bolt threads before fitting them
back: they could come loose.
Wheel bolts are specific
for the type of rim (alloy
or steel) fitted. Never use,
also if in an emergency, wheel
bolts for another type of rim.
When changing rims (alloy rims
instead of steel ones or vice
versa), also the whole wheel bolt
set shall be changed with other
bolts specific for the new type of
rim adopted.The jack should only be
used to change a wheel on
the car for which it was
designed. It should not be put to
other uses or employed to raise
other models of car. Under no
circumstances should it be used
when carrying out repairs under
the car.
An incorrectly positioned jack
may cause the car to fall.
Do not use the jack to lift loads
exceeding those indicated on the
label attached to the jack itself.
The wheel cap may fly off when
the car is moving if it is not fas-
tened correctly. Never tamper
with the inflation valve. Do not
insert tools between the rim and
the tyre.
Check the tyre and spare wheel
pressure regularly. Tyre pressure
is shown in the “Technical
Specifications” chapter.
