INSTRUMENT
PANEL WARNING
LIGHTS AND
MESSAGES
On the instrument panel are set the
main warning lights. Certain warn-
ing lights with the relevant warning
messages are present also on the
instrument panel multifunction dis-
play.
Many indications/info are displayed
with a symbol only on the multifunc-
tion display with the corresponding
warnings for the driver.
IMPORTANTIndications may
vary according to the car version.GENERAL NOTES
Failure indications shown on the
multifunction display together with
buzzer sounding and warning light
(if any), are accompanied by spe-
cificwarning messages(e.g. “GO
TO DEALER”, “SWITCH OFF
ENGINE”, etc.). These indications
areconciseandcautionaryand are
aimed to suggest the prompt action
the driver must adopt when a car
malfunctioning appears. These indi-
cations, however, shall not be con-
sidered as exhaustive and/or as an
alternative to the specifications con-
tained in this Owner Handbook,
which shall always be read through
carefully and thoroughly. In case of
failure indication always refer to
the specifications contained in
this chapter.Failure indications displayed on
the multifunction display are divid-
ed into two categories: very serious
failures and serious failures. The
message and the warning indication
corresponding to very serious fail-
ures are displayed alternately for
few seconds. This “cycle” is repeat-
ed indefinitely and it stops any pre-
vious indication on the display. It is
displayed every time the ignition key
is turned to MAR, until the cause of
malfunctioning is removed. To stop
this “cycle”, briefly press (less than
two seconds) the trip meter reset
button. In this case the failure sym-
bol stays on the display in the cen-
tral area until the cause of malfunc-
tioning is removed.

REAR SIDE BAGS
DEACTIVATED
(where provided)
The warning light comes on when
rear side bags are deactivated by the
relevant key switch.EOBD ENGINE
CONTROL SYSTEM
FAILURE
In normal conditions, turning the
ignition key to MAR, the warning
light turns on, but it should go off
when the engine has started.
If the warning light stays on or
turns on when travelling together
with message “ENGINE CONTROL
SYSTEM FAULT” on the multi-
function display:
Glowing steadily- means a fault
in the supply/ignition system which
could cause high emissions at the
exhaust, possible lack of perfor-
mance, poor handling and high con-
sumption levels.
In these conditions it is possible to
continue driving without however
demanding heavy effort or high
speeds. Prolonged use of the car with
the warning light on may cause
damages. Contact a Lancia
Dealershipas soon as possible.
The warning light goes off if the
fault disappears but it is however
stored by the system. FRONT PASSENGER
AIRBAG DEACTIVATED
The warning light comes
on when front passenger airbag is
deactivated by the relevant key
switch.
SEAT BELTS
The warning light comes
on with ignition key at
MARwhen the driver’s seat belt is
not fastened.

REAR FOG LIGHTS
The warning light comes
on when rear fog lights are
on.
AIRBAG SYSTEM
FAILURE
Turning the ignition key
toMAR, the warning light turns on
but it should go off after a few sec-
onds. The warning light comes on
with message “AIRBAG SYSTEM
FAULT” on the multifunction dis-
play to indicate an airbag system
failure.

¬
If the ¬warning light
does not turn on when
turning the ignition key to
MAR or if it stays on when travel-
ling, (together with message on
display) this could indicate a fail-
ure in safety retaining systems; un-
der this condition air bags or pre-
tensioners could not trigger in the
event of collision or, in a restricted
number of cases, they could trig-
ger accidentally. Stop the car and
contact Lancia Dealership to have
the system checked immediately.

LOW BRAKE FLUID
LEVEL
Turning the ignition key
toMAR, the warning light turns on
but it should go off after a few sec-
onds.
The warning light comes on togeth-
er with the message “LOW BRAKE
FLUID LEVEL” on the multifunc-
tion display, when the level of the
brake fluid in the reservoir falls
below the minimum level, due to
possible leak in the circuit.
118
INJECTION SYSTEM
FAILURE
(where provided -
JTD versions)
In normal conditions, turning the
ignition key to MAR, the warning
light turns on but it should go off
after a few seconds.
If the warning light stays on or turns
on while travelling together with the
message “ENGINE CONTROL SYS-
TEM FAULT” on the multifunction
display, this indicates that the injec-
tion system is not working perfectly
with possible lack of performance,
poor handling and high consumption.
In these conditions it is possible to
continue driving without however
requiring heavy effort or high speed
from the engine. In any case, contact
aLancia Dealershipas soon as
possible.
Do not use the car for long periods
at high speed with this warning light
on since this could result in serious
damages especially in case of irregu-
lar operation or misfiring.
Ux
Flashing- indicates the possibility
of damage to the catalyst (see
“EOBD system” in this chapter).
If the warning light flashes, it is
necessary to release the accelerator
pedal to lower the speed of the
engine until the warning light stops
flashing; continue driving at moder-
ate speed, trying to avoid driving
conditions that may cause further
flashing and contact a Lancia
Dealershipas soon as possible.
If, turning the ignition
key to MAR, the Uwarn-
ing light does not turn on
or if it turn on glowing steadily or
flashing when travelling, contact
a Lancia Dealership.

119
ABS SYSTEM FAILURE
Turning the ignition key
toMAR, the instrument
panel warning light turns on but it
should go off after a few seconds.
When there is failure the warning
light stays on or comes on when
travelling together with message
“ABS SYSTEM FAULT” on the
multifunction display. In this case
the braking system keeps its effec-
tiveness unchanged, but without the
potential offered by the ABS system.
It is however recommended to con-
tact a LanciaDealershipas soon
as possible.
In the event of instrument panel
warning light failure, the warning
light on the multifunction display
comes on together with message
“ABS INDICATOR FAULT”: con-
tact a Lancia Dealershipas soon
as possible.In this case heavy brak-
ing may cause the rear
wheels to lock before
time, with the possibility of skid-
ding, stop the car immediately
and contact a Lancia Dealership.

EBD SYSTEM
FAULT
(ELECTRONIC
BRAKEFORCE DISTRIBUTOR)
The car is fitted with electronic
braking distributor (EBD). The
turning on at the same time of the
xand>warning lights on the
instrument panel together with mes-
sage “EBD SYSTEM FAULT” on
the multifunction display with the
engine running indicates an EBD
system failure.

If the xwarning light
comes on when travelling,
stop immediately and
contact a Lancia Dealership.
In the event of instrument panel
warning light failure, the warning
