If the failure is signalled when the
engine is started, it means that the
electronic control unit had stored it
previously, before stopping the
engine. Even in this case, go to a
Lancia Dealershipto have the
automatic gearbox checked.
When driving with auto-
matic gearbox faulty,
drive carefully consider-
ing the limited car efficiency in
terms of acceleration and speed.
In addition, when driving with
automatic gearbox faulty, the
reverse block might not be oper-
ating: for this reason it is
absolutely necessary to move the
lever to position R while the car
is moving.SOUND SIGNAL
A buzzer will sound in the follow-
ing conditions:
– for about 15 seconds when the
driver’s door is opened while the
engine is running or not and the gear
lever has a position different from P
– for about 15 seconds when the
engine is turned off and the gear
lever has a position different from P
– for about 4 seconds when the
gear lever is shifted to R(reverse)
– with the manual sequential oper-
ation on, when the selected gear is
not accepted by the electronic con-
trol unit (e.g. since it might generate
a runaway speed rate). BUMP STARTING
Never bump starting the engine (by
pushing, towing, etc.). In an emer-
gency, when the battery is flat, start
the engine with the appropriate
emergency battery according to the
instructions contained in chapter “In
an emergency”.

To make ESP, ASR and
ABS systems work prop-
erly, the tyres must
absolutely be of the same brand
and type on all wheels, in perfect
conditions and, above all, of type,
brand and size specified. stantly changed and controlled in
the attempt to keep the driver’s
direction.
The ESP system considerably
increases the car safety in several
critical conditions and it is particu-
larly useful during overtaking, when
the grip conditions on the road bed
change.ASR FUNCTION (ANTISLIP
REGULATION)
General
The ASR function is part of the
ESP system and it checks the car
drive, taking action every time one
or both driving wheels slip, thus pre-
venting car instability and tyre wear.
On the basis of slipping conditions,
two different check systems are acti-
vated:
– if slipping affects both driving
wheels, as a result of the excessive
force transmitted, the ASR function
reduces the power supplied by the
engine;
– if slipping affects only one of the
driving wheels, the ASR function
automatically brakes the slipping
wheel, with an effect similar to the
self-locking differential.The action of the ASR function is
particularly useful in the following
conditions:
– internal wheel slipping when cor-
nering due to load dynamic varia-
tions and excessive acceleration;
– excessive power supplied to
wheels according to the road bed;
– acceleration on slippery ground,
covered with snow or ice;
– in case of grip loss on wet ground
(aquaplaning).
ASR function activation
The ASR function is activated
automatically whenever the engine
is started.
During driving it is possible to dis-
engage and engage this function by
pressing button A(fig. 142) on the
central console.
When the ASR function is on, sym-
bol Vis lighted on the multifunc-
tion display together with the mes-
sage “ASR ON”.

The driver will be warned by a spe-
cial display message when the system
is deactivated because the lens is
dirty.In this case, clean the sensor protec-
tion lens, shown in fig. 150with a wet
cloth; do not use dry, rough or hard
cloths. Should the dirty lens message
stay on after cleaning, contact a Lan-
cia Dealership.
If the Radar Cruise Con-
trol went off due to exces-
sive lens dirt, when
restarting the car a few km shall
be covered before switching the
system on again in order to let the
system check if previous condi-
tions (causing Radar Cruise Con-
trol turn off) have been removed.The sensor is built into
the front bumper: impacts
can therefore damage it.
IMPORTANTFailure to one of the
safety systems connected to the Radar
Cruise Control (ABS or ESP system)
will cause Radar Cruise Control fail-
ure indication.
The Radar Cruise Control
should be switched on
only when road and traffic
conditions allow the driver to drive
safely, that is, when the road is
straight and the surface is not slip-
pery, when the car is driven on a
freeway or motorway, and when
traffic flows smoothly. Do not use
the device when driving in urban
areas or when traffic is heavy.

Do not use the Radar
Cruise Control under poor
visibility conditions (e.g.:
fog, heavy rain, snow, etc.), since
the system performance could be
badly affected.
IMPORTANTAs you approach a
bend, it may be necessary to reduce
the stored speed or switch the system
off by pressing the brake pedal.
The brake pedal is oper-
ated by the Radar Cruise
Control system: do not po-
sition your foot under the brake
pedal.IMPORTANTThe Radar Cruise
Control can only be switched on when
the car speed ranges from 30 and 160
km/h. The Radar Cruise Control is
automatically switched off when any
of the ABS, ASR, MSR and ESP sys-
tems comes into operation. Moreover,
it is switched off when engaging re-
verse gear, neutral or the electronic
parking brake (EPB).
IMPORTANTThe Radar Cruise
Control cannot be activated when the
driver has switched the ASR system
off.In the device is faulty or
does not work, turn ring A
to OFF and contact a Lan-
cia Dealership
IMPORTANTRing Acan be con-
stantly left in a position other than
OFFwithout damaging the Radar
Cruise Control. The device should
however be switched off when not in
use by turning ring Ato OFFto pre-
vent storing speeds accidentally.

THE USER
If after buying the car, you decide
to install electrical accessories that
require a permanent power supply
(e.g. satellite antitheft device), or
any other accessory that burden the
electric supply, contact your Lancia
Dealershipwhose qualified person-
nel, besides suggesting the most suit-
able devices belonging to the
Lineaccessori Lancia, will also eval-
uate the total electrical absorption,
checking whether the car’s electric
system is able to withstand the
required load or whether it must be
integrated with a more powerful
battery.

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.

STARTING
THE ENGINE
IMPORTANTThe car is equipped
with electronic engine immobilising
system. If the engine fails to start,
see paragraph “Lancia CODE sys-
tem”.
We recommend that
during the initial period
you do not drive to full
car performance (e.g.: excessive
accelerations, long journeys at
top speed, sharp braking etc.).It is dangerous to let the
engine run in a garage or
other closed area. The
engine consumes oxygen and
gives off carbon oxide, a poiso-
nous gas.
The ignition device is fitted with a
safety device which obliges the dri-
ver to return the key to STOPposi-
tion before repeating the starting
procedure.
In the same way, when the engine
is running, this device prevents any
shift from MARto AVV.Never leave the ignition
key at MAR when the
engine is off to prevent
battery draining due to current
absorption.
