If, on the contrary, the warning
lamp remains on, go to a Lancia
Dealershipto 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
Dealershipduring 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
EQUIPMENT
FRONT CEILING LIGHT
(fig. 159)
This ceiling light includes a central
light and two courtesy lights.
To switch the central light on man-
ually, press button A; to switch it
off, press the same button again.
The light will light up and go out
gradually. If the ceiling light has
been switched on by means of the
button, it will automatically go out
after about 15 minutes after the
engine has been shut off (by turning
key to STOP).

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.

256
Make sure that any mats
are appropriate in size:
any hindrance, even
slight, to the braking system may
require a higher pedal stroke
than normal.
Water, ice and salt on
the road may deposit on
brake disks, reducing
braking efficiency the first time
they are used.Driving while drunk or
under the influence of
drugs or certain medi-
cines is dangerous both for you
and other road users.
Always fasten both front
and back seat belts,
including child restraint
systems if there are children trav-
elling with you. Travelling with
seat belts unfastened increases
the risk of injury or death if you
are involved in a collision. Take care when fitting
additional spoilers, alloy
rims and wheel caps: they
might reduce ventilation of the
brakes, thus their efficiency dur-
ing abrupt braking or long down-
hill slopes.
Never drive with objects
on the floor in front of the
driver’s seat: they might
get stuck under the pedals mak-
ing it impossible to accelerate or
brake.

257
– Keep a greater safety distance
from the cars in front of you than
during daylight hours: it is hard to
judge how fast other cars are going
when all you can see are their lights.
– Only use main beam headlights
when you are driving outside town
and when you are sure they do not
annoy other drivers.
– Dip your headlights as soon as
you see cars coming in the other
direction and pass them with the
headlights dipped.
– Keep all lights clean.
– Be careful of animals crossing the
road when driving in the country.
DRIVING IN THE RAIN
Rain and wet road surfaces spell
danger.
All manoeuvres are more difficult
on a wet road because the grip of the
wheels on the tarmac is greatly
reduced. This is why braking dis-
tances are much longer and road-
holding is lower.Here is some advice for driving in
the rain:
– Reduce speed and maintain a
greater safety distance from the cars
in front.
– If it is raining particularly heavi-
ly, visibility is also reduced. In these
cases, switch on the dipped head-
lights even if it is still daylight so you
can be seen more easily.
– Do not drive through puddles at
speed and hold on tightly to the
wheel if you do: a puddle taken at
high speed might cause you to lose
control of the car (“aquaplaning”).
– Move the ventilation controls to
the position for demisting the win-
dows (see the section “Getting to
know your car”), so to avoid visibil-
ity problems.
– Periodically check the condition
of the windscreen wiper blades. – Do not drive too many hours at a
time but stop at intervals to stretch
your legs and recoup your energy.
– Make sure the air in the car is
being changed continuously.
– Never coast downhill (i.e.: with
the engine off): if you do, you lose
the aid of engine braking and power
brakes so that braking requires
greater effort.
DRIVING AT NIGHT
There are the main rules to follow
when you are driving at night.
– Drive especially carefully: it is
harder to drive at night.
– Slow down especially if the road
is not lit.
– At the first signs of sleepiness,
stop: continuing would be a risk for
yourself and everybody else. Only
start driving again when you have
had enough rest.

258
DRIVING IN FOG
If the fog is thick, do not start out
on a journey unless you absolutely
have to. If driving in mist, blanket
fog or when there is danger of fog
patches:
– Keep your speed down.
– Turn on the dipped headlights,
rear fog lights and front fog lights
even during the day. Do not drive
with your headlights at main beam.
IMPORTANTOn stretches of road
with good visibility, switch off your
rear fog lights; the brightness of
these lights could annoy the people
travelling in the cars behind.
– Remember that fog also means
the tarmac is very wet and therefore
manoeuvres of all kinds are more
difficult and stopping distances are
longer.
– Keep a good distance from the
cars in front of you.
– As far as possible, avoid spurts of
speed or sudden decelerations. – Do not overtake other vehicles if
you can help it.
– If you are forced to stop your car
(breakdown, limited visibility etc.),
try to stop off the road. Turn on the
hazard lights and, if possible, the
dipped beam headlights.
Rhythmically sound the horn if you
realise another car is coming. DRIVING IN THE MOUNTAINS
– When driving downhill use the
engine braking effect by engaging a
low gear so as not to overheat the
brakes.
– Under no circumstances should
you drive downhill with the engine
off or with the gear in neutral, let
alone with the ignition key out.
– Drive at a moderate speed with-
out cutting corners.
– Remember that overtaking while
going uphill is slower and therefore
requires more free road. If you are
being overtaken while driving
uphill, make it easier for the other
vehicle to pass.
