2006 Lancia Thesis warning light

177
“Automatic parking brake” function
and the press “OK”. Deactivation of
automatic operation can be achieved
also in the following way:
– turn the key to STOP(the park-
ing brake is engaged)
– turn the key back to MAR,
depress the brake pedal and at the
same time keep button Apressed for
at least 2 seconds. Warning light x
flashes thrice to indicate the auto-
matic operation deactivation.
When the key is turned again to
STOPthe parking brake will not be
engaged. The parking brake auto-
matic operation will be automatical-
ly restored when the key is turned
again to MAR.IMPORTANTIf, after the parking
brake has been disengaged, the car
starts moving at a speed higher than
the usual manual movement, deacti-
vation of the automatic mode is
immediately cancelled and the park-
ing brake is engaged.
If, after the parking
brake has been disen-
gaged, the car starts mov-
ing at a speed higher than the
usual manual movement, deacti-
vation of the automatic mode is
immediately cancelled and the
parking brake is engaged.Proceed as follows: release the
accelerator pedal, press and keep
button A(fig. 133) pressed for the
whole manoeuvre: the system elec-
tronic control unit will come imme-
diately into action with alternate
braking on/off cycles on the rear
wheels (thus preventing wheel lock-
ing). Braking cycles are applied
alternately on right and left wheel to
guarantee roadholding, braking
continuity and to reduce braking
distance.
Wheel locking could take place
under the safety speed threshold
(lower than 10 km/h).
A buzzer will sound during the
whole manoeuvre to indicate that
the dynamic mode shall only be used
in an emergency, but this is also use-
ful to warn the driver if the parking
brake has been inadvertently
engaged by other passengers.
Use in an emergency
In particular cases (e.g. fault in the
whole hydraulic brake system, both
service and emergency brake), the
parking brake can be used to stop
the car running (“dynamic mode”).

Fault indication
The system is controlled by an elec-
tronic control unit signalling possible
failures by turning on the s! warn-
ing light on the multifunction display
together with the message “EPB
FAULT - GO TO DEALER”.
For a higher safety, every time the
parking brake button is pressed dur-
ing a failure, a buzzer will sound to
draw the driver’s attention and the
xwarning light will turn on.
If the parking brake does not reach
the required working force (e.g.
when the battery is partially flat),
the instrument panel warning light
xstarts flashing.
In case of instrument panel warn-
ing light xfault, the s!warning
light on the multifunction display
turns on together with the message
“EPB INDICATOR FAULT - GO TO
DEALER” to informthe driver
about the dangerous situation. In case of failure indi-
cated by the related
warning light and mes-
sage turning on, drive carefully to
a Lancia Dealership because the
parking brake might not work.
Emergency disengagement
The electric parking brake is fitted
with an independent battery which
can be used to disengage the brake,
for instance when the car main bat-
tery is completely flat or it has bro-
ken after an accident.The additional battery, always
kept charged by a dedicated elec-
tronic control unit, can engage and
disengage the parking brake when it
is necessary to push manually the
car.
To engage and disengage the elec-
tric parking brake when the car
main battery is completely flat, turn
the key to MARand press the main
button on the central console.

187
Even in fault conditions it is possi-
ble to move the lever to R, Nand D.
If the lever is in position D,the con-
trol unit of the automatic gearbox
will select only certain gears, accord-
ing to the type of failure detected.
In case of failure of the
automatic gearbox, take
the car immediately to a
Lancia Dealership to have the
failure eliminated.FAILURE INDICATION
Automatic gearbox faults are indi-
cated by multifunction display
warning light tcoming on with
the following messages:
– AUTOMATIC TRANSMISSION
OIL TEMP. HIGH
– AUTOMATIC TRANSMISSION
FAULT.
Automatic transmission oil tem-
perature high
This message is displayed when the
gearbox oil has reached the maxi-
mum preset temperature. In this
case the electronic control unit has
an emergency programme.
Anyway, it is suggested to stop the
car, to set the lever to Por Nand to
keep the engine running idle until
the message displayed disappears.
Then start driving again without
taxing the engine.If the message is displayed again,
re-stop the car and let the engine
run idle until the message disap-
pears.
If the interval between the first and
second message appearance is lower
than 15 minutes, stop the car, stop
the engine and wait until the engine-
gearbox unit is completely cold.
Automatic transmission fault
If this message is displayed during
driving, it means that there is a fail-
ure in the automatic gearbox. In this
case the electronic control unit has
an emergency programme.
In such conditions, stop the car and
stop the engine for at least 1 minute.
When the engine is restarted, the
self-diagnosis system could exclude
that failure, that however will be
stored by the electronic control unit.

192
When the ASR function is off, sym-
bol Vis 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”.

Ring Ahas four positions:
OFF: system off
x: greatest distance from the vehi-
cle ahead
x: intermediate distance from the
vehicle ahead
x: shortest distance from the vehi-
cle ahead.
The distance between the two vehi-
cles is gradually increased as the
speed is increased, set levels being
equal.
IMPORTANTTurn the ignition
key to STOPor ring Ato OFF, to
delete the stored speed and switch
the system off. To restore system
operation, turn the ring Ato OFF
and repeat the setting operations.When the system is on, that is, ring
Ais in any position other than OFF,
symbol úlights up on the multi-
function display, together with mes-
sage “RADAR CRUISE CONTROL
ON”. The warning light will remain
on until the system is switched off by
turning ring Ato OFF.
Ring Bis used to store the car
speed and keep it constant, or to
increase or decrease the stored
speed.
Turn ring Bto (+) to store the
speed reached or increase the stored
speed.
Turn ring Bto (–) to decrease the
stored speed. Slowing down can also
be obtained, when required, by
braking system automatic operation.
Every time ring Bis turned, the
speed is increased or decreased by
about 1 km/h. By keeping the ring
rotated, the stored speed will change
continuously at intervals of 10
km/h. The new speed reached will
be maintained automatically.
When ring Bis turned, the car’s
actual speed is considered as refer-
ence speed (cruise speed). This
speed can automatically decrease
depending on traffic conditions, and
the system can shift from the speed
control condition to the distance
control condition. The driver is
informed of the system’s operating
condition by the instrument panel
display.
Button C(RCL) allows to reset the
stored speed. In fact, when driving
the car with the system on, the dri-
ver can switch the system off by sim-
ply braking. In this case, the cruise
speed previously set is kept in the
memory and can be enabled again at
any time by pressing button RCL.

PARKING SENSOR
The parking sensor provides dis-
tance information to the driver when
the car moves near obstacles placed
in front of and behind it.
The information on the presence
and distance of obstacles is sent to
the driver by means of sound sig-
nals, the frequency of which
depends on the obstacle distance.
By integrating the direct visual
information with the sound signal
emitted by the system, the driver can
therefore avoid possible collisions.
208
The responsibility for
parking manoeuvres and
other dangerous manoeu-
vres always rests with the driver.
When performing such manoeu-
vres, always make sure that no
persons or animals stand in the
area where the car is to be
parked. The parking assist sys-
tem should be considered as an
aid to the driver; in any case,
greatest attention must be paid
when performing dangerous
manoeuvres, even at low speed.
The system front and rear sensors
are activated automatically when
engaging reverse with the ignition
key at MAR. Disengaging the
reverse gear will turn the rear sen-
sors off; front sensors will stay on
until 15 km/h speed is exceeded to
allow concluding the parking
manoeuvre.Front sensors can be switched on
by pressing button A(fig. 155)
placed on the central console in
front of the gear lever; when the
front sensors are on, warning light
Blights up on the button. To
switch the sensors off, press button
Aagain.
When the sensors are on, the sys-
tem starts sending out sound sig-
nals from the front or rear buzzers
as soon as an obstacle is detected;
the signal frequency increases as
the obstacle gets nearer. When the
obstacle is at a distance of less than
30 cm, a continuous sound is emit-
ted. Depending on the position of
the obstacle (in front or behind),
the sound will be emitted from the
corresponding buzzer (front or
rear). The sound signal will imme-
diately stop if the distance from the
obstacles increases. The tone cycle
remains the same if the distance
measured by the central sensors
does not change; however, if this
condition occurs with side sensors,
the signal will be interrupted after
about 3 seconds, to avoid, for
instance, sending out signals in
case of parking manoeuvres along
walls.

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
