If these rules are not
respected, the automatic
gearbox might be severely
damaged.
The car can be towed only for
short distances and at a low
speed: if it is necessary to tow it
for a longer distance, raise the
driving wheels so that the gear-
box is not dragged during towing. TOWING THE CAR
IMPORTANTTo tow the car
observe local current laws and fol-
low the instructions contained in
chapter “In an emergency”.
If the car must be towed, observe
the following precautions:
– if possible, transfer the car on a
towtruck
– otherwise, tow the car by raising
the front driving wheels
– even if the latter solution is not
possible, the car can be towed for
less than 50 Km at a speed of 50
km/h.
Towing shall be performed with
gear lever to N.Before starting towing,
disengage the parking
brake as described in the
relevant paragraph and leave the
Keyless System CID (if any) in the
passenger’s compartment to pre-
vent automatic steering lock. Do
not tow the car with the engine
running.
ESP AND ASR
SYSTEMS
ESP SYSTEM (ELECTRONIC
STABILITY PROGRAM):
GENERAL
ESP is an electronic system con-
trolling the car stability which
affects the driving torque and brakes
the wheels in a different way in case
of grip loss, thus making the car
recover the right driving direction.
During driving the car is subject to
side and longitudinal forces which
can be controlled by the driver until
tire grip is acceptable. When the lat-
ter is lower than the minimum level,
the car starts skidding.
If the road bed is uneven (bumpy
road, presence of ice, mould, etc.)
tyre grip is considerably reduced. In
these conditions, when extreme
manoeuvres are made, the car might
start skidding.

190
If the sensors detect the conditions
which might cause car skidding, the
ESP system affects the engine and
the brakes by generating a torque
which makes the car recover the
right driving direction.
The system operations,
in terms of safety, should
not make the driver run
useless risks. The driving behav-
iour must always be appropriate,
according to the conditions of the
road bed, visibility and traffic.
Anyway, the driver is held
responsible for a safe driving.
The ESP system helps the driver
control the car in case of tyre grip
loss, however the forces used by
the system to control the car sta-
bility still depend on the grip
ratio between tyres and road bed.ESP SYSTEM OPERATION
ESP is automatically started when
the car is started and it cannot be
disengaged. On the contrary, it is
possible to exclude the ASR system
by pressing the related button on the
central console.
The ESP main components are the
following:
– an electric-hydraulic control unit
processing signals coming from the
various sensors and choosing the
most appropriate strategy by operat-
ing solenoid valves and the engine
control unit;
– a sensor detecting the steering
wheel rotation angle;
– 4 sensors detecting the rotation
speed of each wheel;
– a sensor detecting the car rota-
tion around a vertical axis;
– a sensor detecting side accelera-
tion (centrifugal force).The ESP core is a sensor, of aero-
nautic origin, detecting the car rota-
tions around its vertical axis.
Centrifugal forces generated when
the car is cornering are detected by a
high-sensitive side acceleration sen-
sor.
The ESP stabilizing action is based
on the signals coming from the steer-
ing wheel rotation sensors, from the
side acceleration sensors and the
wheel speed sensors, thus recogniz-
ing the driving direction selected by
the driver when turning the steering
wheel.
The control unit processes each
information coming from the sensors
and is able to recognize every single
moment of the car position and to
compare it with the direction the
driver is willing to follow. In case of
discrepancy, the control unit
instantly selects and controls the
most appropriate actions to make
the car recover the required direc-
tion: it brakes with a different inten-
sity one or more wheels and, if nec-
essary, reduces the power supplied
by the engine. Corrections are con-

191
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-
bolVis lighted on the multifunc-
tion display together with the mes-
sage “ASR ON”.

192
When the ASR function is off, sym-
bolVis lighted on the multifunc-
tion display together with the mes-
sage “ASR OFF”.
The function deactivation is indi-
cated by switching on of the related
warning light Bon the button. If this
function is deactivated during dri-
ving, it will be reactivated automat-
ically at the following start up.
IMPORTANTDuring driving on a
snow-covered ground, with snow
chains on, it might be useful to deac-
tivate the ASR function: in these
conditions driving wheel slipping at
start up is useful to reach higher
drive.MSR SYSTEM
(ENGINE DRIVE ADJUSTMENT)
The car is fitted with a system, part
of ASR, affecting the engine torque
in case of sudden gear shift, thus
preventing excessive driving wheel
dragging which, in extremely low
grip conditions, can make the car
loose stability.
ESP SYSTEM ACTION
The ESP action is indicated by
flashing of warning light áon the
instrument panel, to inform the dri-
ver that the car is in critical stability
and grip conditions.
ESP AND ASR FAILURE
INDICATION
In case of failure, ESP and ASR
systems are automatically deactivat-
ed and symbol áand message “ESP
FAULT” will come on with fixed
light on the multifunction display
together with warning light Bon the
ASR button.
If the failure affects only the ESP
system, symbol áand message“ESP FAULT” are lighted on the
multifunction display, while the
warning light on button Bis off and
the ASR system remains operating.
If the failure affects only the ESP
system, symbol áand message
“ESP FAULT” are lighted on the
multifunction display, while the
warning light on button Bis off and
the ASR system remains operating.
In case of ESP or ASR failure, the
car behaves in the same way as a car
that is not fitted with this system: in
any case it is advisable to contact a
Lancia Dealershipas soon as pos-
sible.

INITIALISING THE ESP SYSTEM CONTROL UNIT
Whenever the battery is electrically connected again or it is reloaded after being completely flat or after replacing one of
the protection fuses, to restore the correct operation of the ESP system, of the door locking, and of the air conditioning, it
is necessary to perform the initialisation operations contained in the paragraph “If battery is to be disconnected” in the chap-
ter “In an emergency”.

or
– by momentarily turning ring Bto
(+): each turn of the ring will corre-
spond to a small speed increase
(approximately 1 km/h), while a
continuous pressure will correspond
to a continuous speed increase.
Release ring B: the new speed will
automatically be stored.
Reducing the stored speed
The stored speed can be decreased
in two ways:
– by switching the device off (e.g.
by pressing the brake pedal) and
then storing the new speed (turning
ringBto (+) for longer than three
seconds)
or
– by turning ring Bto (–) until the
new speed is reached. The new speed
will automatically be stored.Deleting the stored speed
The stored speed is automatically
deleted when:
– the engine is stopped
or
– switch Ais turned to OFF.
When driving with the
cruise control, do not
shift the gear lever to neu-
tral. You should only switch the
cruise control on when the traffic
and road conditions allow this in
complete safety, i.e. straight and
dry roads, motorways, fast mov-
ing traffic and smooth road sur-
face. Do not use the device in
cities or in heavy traffic.The cruise control can
be switched on at speeds
higher than 30 km/h (40
to 180 km/h for 2.4 JTD 20V CAE
version). The device can only be
switched on in 4th, 5th or 6th
gear, according to car speed. In
versions with automatic trans-
mission, the device must only be
switched on with the gear lever at
D during automatic operation
without shifting the lever subse-
quently, or with the 3
rdor 4thgear
engaged during manual sequen-
tial operation.
When travelling down-hill the
speed may increase with respect
to the stored value according to
the change in engine load.

201
Deleting the stored speed
The stored speed is automatically
deleted when:
– the engine is stopped
– ring Ais turned to OFF.
When the system is switched off,
any information shown on the
instrument panel display will be
deleted.
Maintaining speed and distance
The system will maintain the
stored speed when no vehicle is
detected along the running path. If,
on the contrary, a vehicle is detected
which runs at a low speed, the sys-
tem will automatically perform the
operations (acceleration, decelera-
tion or slight braking) required to
keep the set distance from the vehi-
cle ahead.The maximum decelera-
tion performed by the sys-
tem automatically is lim-
ited compared to the actual brak-
ing power of the brake system;
therefore, emergency braking can
and must be performed only by
the driver. A buzzer will warn the
driver that the brakes shall be
applied.Detecting a vehicle with the
system active but not switched on
When the system is active (ring A
set to any position other than OFF),
it can detect the presence of a vehi-
cle only after it has been switched on
at least once (by turning ring Bto
(+).
Subsequently, the presence of a
running vehicle will always be indi-
cated, even when the system is off,
until deactivating the system (ring A
set to OFF).
Pressing the brake pedal will
switch the system off, whereas it will
always be possible to accelerate, (e.g
for overtaking), without switching
the system off; the system will auto-
matically bring the car back to the
stored speed when the accelerator
pedal is released (provided that 160
km/h speed has not been exceeded).
The multifunction display gives to
the driver concise information on the
stored speed, the presence of a run-
ning vehicle (if any) and the set dis-
tance.

211
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

212
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
