SPEEDOMETER (SPEED INDICATOR)

Indicator A shows the speed of the car.

REV COUNTER

Indicator D shows the engine revs.

FUEL LEVEL GAUGE 

Indicator B shows the amount of fuel in the tank.
The 

K

warning light will switch on (together with a mes-

sage on the display) to indicate there are between 5 and
7 litres of fuel remaining.
Do not travel with the fuel tank almost empty: any gaps
in fuel delivery could damage the catalytic converter.

ENGINE COOLANT TEMPERATURE GAUGE

Gauge C shows the temperature of the engine coolant and
indicates when the coolant temperature exceeds 50°C. The
first reference remains on constantly to indicate that the
system is operating correctly. The 

u

warning light switch-

es on (together with a message on the display) to indi-
cate that the temperature of the engine coolant has in-
creased significantly. In this event, stop the engine and
go to a Lancia Dealership.

INSTRUMENT PANEL WARNING LIGHTS

Important information
The warning lights switch on together with a dedicated
message and/or a buzzer where appropriate. These indi-
cations are precautionary and as such must not be con-
sidered as exhaustive and/or alternative to the informa-
tion contained in the Owner Handbook, which you are ad-
vised to read carefully in all cases. Always refer to the in-
formation in this chapter in the event of a failure indica-
tion.

Low brake fluid level (red)

Turning the key to the MAR position illumi-

nates the warning light, but it should switch off

after a few seconds. The warning light switches

on when the brake fluid in the reservoir falls below the
minimum level, possibly due to a leak in the circuit. The
display shows the dedicated message.

Handbrake on (red)
When the key is turned to MAR, the warning light switch-
es on but it should switch off after a few seconds. The
warning light switches on when the handbrake is engaged.
If the car is moving the buzzer will also sound.

IMPORTANT If the warning light turns on when travel-
ling, check that the handbrake is not engaged.

KNOWING YOUR CAR

If the x warning light turns on when trav-
elling (with the message on the display) stop
the car immediately and contact a Lancia

Dealership.

Brake pad wear (amber)

The warning light (or symbol on the display)

switches on when the front brake pads show

signs of wear; under these circumstances have

them replaced as soon as possible. The display shows the
dedicated message.
IMPORTANT Because the car is equipped with a wear de-
tection system only for the front brake pads, when these
are replaced the rear brake pads should also be checked
for wear.

d

Airbag failure (red)

When the key is turned to MAR, the warning

light switches on but it should switch off after

a few seconds. The warning light stays on con-

stantly if there is a fault in the airbag system. 
The display will show the dedicated message.

¬

If the ¬ warning light does not come on when
the key is turned to MAR or if it stays on with
the car in motion (together with the message

on the display) there could be a fault in the restraint
systems; under these circumstances, the airbags or
pretensioners may not be deployed in the event of
an impact or, more rarely, they could be deployed
accidentally. Contact a Lancia Dealership to have
the system checked immediately.

The failure of the ¬ warning light is indi-
cated by the “ warning light flashing longer
than the expected 4 seconds, which signals

that the front passenger airbag is deactivated. In
addition, the airbag system automatically deacti-
vates the passenger side airbags (front airbag and
side bag). In this case, the ¬ warning light may not
indicate failures in the retaining systems. Before
proceeding, contact a Lancia Dealership to have the
system checked immediately.

EBD failure 

If warning lights x (red) and > (amber) are
on at the same time with the engine running,
this indicates an EBD system failure or that the
system is not available. Early locking of the rear
wheels may occur in the event of sharp brak-
ing, possibly causing the car to swerve. 

Drive very carefully to a Lancia Dealership to have

the system inspected immediately. The display will show
the dedicated message.

Passenger side airbag/side bags 

deactivated (amber)

The “ warning light switches on when the front

passenger’s airbag and side bag are disabled. With

the front passenger airbags activated, when the ignition
key is turned to MAR, the “ warning light switches on
constantly for about 4 seconds, flashes for another 4 sec-
onds and should then switch off.

“

Failure of the 

“

warning light is indicated

by the ¬ warning light coming on. In addi-
tion, the airbag system automatically deac-

tivates the passenger side airbags (front airbag and
side bag for versions/markets, where provided). Be-
fore proceeding, contact a Lancia Dealership to have
the system checked immediately.

Seat belts unfastened (red)

This warning light switches on constantly when

the car is not in motion and the driver side seat

belt is not correctly fastened. The warning light

will flash and a buzzer will sound if the car is in motion
and the front seat belts are not correctly fastened.
The SBR (Seat Belt Reminder) system buzzer can only
be permanently deactivated by a Lancia Dealership. 
The system can be reactivated using the Setup Menu.

<

Low battery charge (red)

The warning light comes on when the ignition

key is turned to MAR, but it should go out as

soon as the engine has started (with the engine

running at idle speed a brief delay before going out is ac-
ceptable).
If the warning light stays on, constantly or flashing, con-
tact a Lancia Dealership immediately.

Continuously on: low engine oil pressure

(red)

Flashing: engine oil deteriorated (red)

When the key is turned to MAR the warning light

comes on, but should go out as soon as the engine is start-
ed. 

1. Low engine oil pressure
The warning light switches on constantly together (for ver-
sions/markets, where provided) with the message on the
display when the system detects that engine oil pressure
is low.

v

If the v warning light turns on when the
car is travelling (on certain versions togeth-
er with the message on the display) stop the

engine and contact a Lancia Dealership immedi-
ately.

KNOWING YOUR CAR

Degraded engine oil should be replaced as
soon as possible after the warning light comes
on, and never more than 500 km after it first

comes on. Failure to observe the above indications
may result in severe damage to the engine and in-
validate the warranty. Remember that when the
warning light comes on, it does not mean that the
level of engine oil is low, so if the light flashes you
definitely do not need to top up the engine oil.

“Dualdrive” electric power steering 

failure (red)

This warning light switches on when the igni-

tion key is turned to MAR, but it should switch off

after a few seconds. 

The electric power steering system will not work when the
warning light is on and considerably more effort is needed
on the steering wheel. The car can still be steered. In this
case, go to a Lancia Dealership. The display will show the
dedicated message.

g

“Dualdrive” electric steering engagement 

The warning light switches on (or the word

“CITY” appears on the display) when the

“Dual drive” electric power steering system is ac-

tivated by pressing the relevant control button. If the but-
ton is pressed again the word CITY goes out.

CITY

2. Degraded engine oil (only versions with DPF)
The warning light will turn on flashing together with the
message on the display (for versions/markets where pro-
vided). Depending on the versions, the warning light flash-
ing modes are as follows:
– for 1 minute every two hours;
– cycles of 3 minutes with intervals with the warning light
off for 5 seconds until the oil is changed.
After the first indication, at each engine start up the warn-
ing light will continue flashing as described above until
the oil is changed. The display (for versions/markets,
where provided), shows a dedicated message together with
the warning light.
The flashing of the warning light should not be consid-
ered as a fault, it simply informs the customer that the
oil needs to be changed following normal car use.
Remember that the deterioration of the engine oil is accel-
erated by:
– mainly town use of the car which makes the DPF re-
generation process more frequent
– use of the vehicle for short drives, in which the engine
does not have time to reach its regular operating tem-
perature 
– repeated interruption of the regeneration process, sig-
nalled by the DPF warning light switching on.

Engine coolant overheating (red)

Turning the key to the MAR position illumi-

nates the warning light, but it should switch off

after a few seconds. The warning light turns on

when the engine is overheated. If the warning light switch-
es on when driving, proceed as follows:
❍ when driving normally: stop the car, switch off the en-

gine and check that the water level in the reservoir is
not below the MIN mark. If it is, wait for the engine
to cool down, then slowly and carefully open the cap,
top up with coolant and check that the level is between
the MIN and MAX marks on the reservoir. Also check
visually for any fluid leaks. in this case, go to a Lan-
cia Dealership if the warning light should switch on
when the engine is started again.

❍ if the vehicle is used under demanding conditions (e.g.

towing trailers uphill or fully loaded): slow down and,
if the light stays on, stop the car. Wait for 2 or 3 min-
utes with the engine running and slightly accelerated
to further favour the coolant circulation. Then stop the
engine. Check the correct coolant level as described
above.

IMPORTANT Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few min-
utes before switching it off. The display will show the ded-
icated message.

Parking sensor fault 
(for versions/markets, where provided)
This warning light (or symbol on the display) switches on
when a fault is detected in the parking sensors. The dis-
play shows the dedicated message.

Tyre pressure monitoring system failure 
(for versions/markets, where provided)
This warning light (or symbol on the display) switches on
when a failure is detected in the TPMS (for versions/ mar-
kets, where provided).
Should one or more wheels without a sensor be fitted, the
instrument panel warning light will come on and stay on
until the initial conditions are restored. The display shows
the dedicated message.

NOTE If one of the failures listed above occurs, contact
a Lancia Dealership as soon as possible.

AFS failure 
This warning light (or symbol on the display) switches on
when a fault is detected in the AFS (see “Headlights” para-
graph in this chapter). The display shows the dedicated
message.

Steering corrector not available
This warning light (or symbol on the display) switches on
when the steering corrector is not available. The display
will show the dedicated message.

DPF (diesel particulate filter) cleaning in

progress (only versions with DPF) (amber)

When the key is turned to MAR, the warning

light switches on but it should switch off after a

few seconds. The warning light turns on constantly when
the DPF system needs to eliminate the trapped pollutants
(particulate) through the regeneration process. 
The warning light does not come on every time the DPF
is being regenerated, rather only when the driving condi-
tions are such that the driver needs to know it. To switch
the warning light off, the car must be kept moving until
the regeneration process is completed. 
On average, the process lasts 15 minutes. The best con-
ditions to complete the regeneration process are reached
driving the car at about 60 km/h with engine speed over
2000 rpm. When this warning light switches on, it does
not indicate a car failure and thus it should not be taken
to a workshop. A dedicated message will appear on the
display when the warning light switches on (for ver-
sions/markets, where provided).

Fuel reserve (amber)

When the key is turned to MAR, the warning

light switches on but it should switch off after

a few seconds. The warning light switches on

when about 5 to 7 litres of fuel are left in the tank.
The display shows the dedicated message.

IMPORTANT The warning light will blink to indicate a sys-
tem failure. Go to a Lancia Dealership to have the system
checked.

K

The driving speed must always be suitable
for traffic and weather conditions and the
driver must always comply with the High-

way Code. The engine can also be switched off if the
DPF warning light is on; nevertheless, repeated in-
terruptions of the regeneration process could cause
an early deterioration of engine oil. For this reason,
always wait until the warning light switches off be-
fore stopping the engine as described above. It is not
advisable to complete DPF regeneration with the
car stationary.

If the warning light remains on or comes on whilst driving,
it means that the injection system is not working proper-
ly; in particular, if the warning light comes on constant-
ly, this indicates a malfunction in the supply/ignition sys-
tem that could cause excessive exhaust emissions, a pos-
sible loss of performance, poor driveability and high fuel
consumption. On some versions the display shows the ded-
icated message. Under these conditions, you may contin-
ue travelling at a moderate speed without demanding ex-
cessive effort from the engine. Prolonged use of the car
with the warning light on constantly may cause damage. 
Go to a Lancia Dealership as soon as possible.
The warning light switches off if the malfunction disap-
pears, but it is still stored by the system.

EOBD/injection system failure (amber)

Under normal conditions, when the ignition key

is turned to MAR, the warning light switches on,

but should switch off as soon as the engine is start-

ed.

U

Go to a Lancia Dealership as soon as possi-
ble if U warning light either does not light
up when the key is turned to MAR or if while

travelling the warning light comes on either con-
stantly or flashing (on some versions along with a
message in the display). The operation of the U
warning light may be checked by the traffic con-
trol authorities using specific devices. Comply with
the laws and regulations of the country where you
are driving.
