ENGINE COOLANT TEMPERA-
TURE GAUGE WITH OVER-
HEATING WARNING LIGHT
(fig. 105)

This instrument indicates the

engine coolant temperature. It starts
signalling the temperature when this
reaches approximately 50 °C.

The needle should usually be on

middle scale values. reduce your
demand on the engine if the needle
approaches top scale values.

The warning light A will come on

together with message “ENGINE
COOLANT TEMPERATURE
HIGH” on the instrument panel dis-
play to indicate that the coolant
temperature is too hot. In this case,
stop the engine immediately and
contact a Lancia Dealership.

IMPORTANT The needle may

approach the top scale values if the
engine cooling radiator external part
is obstructed or dirty. In this case,
inspect and remove the obstructions.
Accurately clean the external part of
the radiator as soon as possible.

FUEL GAUGE AND RESERVE
WARNING LIGHT (fig. 106)

The fuel reserve warning light A

will come on together with message
“REFUEL” on the instrument panel
display to indicate that there are
approximately 10 litres of fuel in the
tank.

IMPORTANT Do not travel with

the fuel tank almost empty: the gaps
in fuel delivery could damage the
catalyst.

109

IMPORTANT

Refuelling shall

always be performed with engine off
and ignition key to STOP. If the
engine is off but the key is to MAR,
a wrong fuel level could temporarily
be indicated. This is due to the inter-
nal system control logic and cannot
be considered as a system malfunc-
tioning.

FLASH CONSUMPTION GAUGE
(fig. 107)

Gauge A shows the flash consump-

tion: to prevent excessively variable
values the gauge shows the average
consumption of the last minutes of
travel expressed in l/100 km (litres
per 100 km). 

This is helpful for the driver for

learning the fuel consumption in
relation to the driving style.

The gauge needle has the following

position:

– value 0 l/100 km with car sta-

tionary

– near value 2 l/100 km when the

car speed is between 4 and 20 km/h
and when releasing the accelerator
pedal during driving

– actual consumption value

(between 2 and 20 l/100 km) for
speeds exceeding 20 km/h.

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.

IMPORTANT Indications 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-
cific warning messages (e.g. “GO
TO DEALER”, “SWITCH OFF
ENGINE”, etc.). These indications
are concise and cautionary and 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.

The message and the warning indi-

cation corresponding to serious fail-
ures are displayed alternately for
few seconds. This “cycle” is repeat-
ed for about 20 seconds and then
goes off, but it comes on again every
time the ignition key is turned to
MAR. At the end of the cycle
(approx. 20 seconds) when pressing
briefly (less than two seconds) the
trip meter reset button, the warning
symbol is reduced to icon at the bot-
tom of the display and the screen
present before the failure returns on
the display. 

117

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
Dealership as 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

MAR when the driver’s seat belt is
not fastened.

AIRBAG SYSTEM 
FAILURE

Turning the ignition key

to MAR, 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

to MAR, 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
a Lancia Dealership as 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.

U

x

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
Dealership as soon as possible.

If, turning the ignition

key to MAR, the U warn-
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

to MAR, 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 Lancia Dealership as 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 Dealership as 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

x and > 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.

x>

If the 

x warning light

comes on when travelling,
stop immediately and

contact a Lancia Dealership.

In the event of instrument panel

warning light failure, the warning
light on the multifunction display

Dealership as soon as possible.

120

ESP SYSTEM (ELEC-
TRONIC STABILITY
PROGRAM) FAILURE 

Turning the ignition key to MAR,

the warning light turns on but it
should go off after a few seconds.

If the warning light does not go off

or stays on when travelling together
with the message “ESP SYSTEM
FAULT” on the multifunction dis-
play, contact a Lancia Dealership.

Warning light flashing when dri-

ving indicates that the ESP system is
active.
