2020 Lancia Ypsilon engine

Warning light What it means
INJECTION / EOBD SYSTEM FAILURE
In normal conditions, the warning light switches on when the key is turned to MAR (on some versions, with
a dedicated message on the display), but should switch off as soon as the engine is started.
If the warning light remains on or switches on whilst driving, the injection system is not working properly; in
particular, if the warning light switches on steadily, this indicates a malfunction in the supply/ignition system
that could cause excessive exhaust emissions, a possible loss of performance, poor driveability and high
fuel consumption.
Under these conditions, the vehicle can continue travelling at moderate speed without demanding
excessive effort from the engine. Prolonged use of the car with the warning light on may cause damage.
Contact a Lancia Dealership as soon as possible.
The warning light switches off if the malfunction disappears, but is still stored by the system.
Petrol engines only
If the warning light flashes, it means that the catalytic converter may be damaged.
In this case, it is necessary to release the accelerator pedal to lower the speed of the engine until the
warning light stops flashing. Continue the journey at moderate speed, trying to avoid driving conditions that
may cause further flashing and contact a Lancia Dealership as soon as possible.
31)
WARNING
31)Go to a Lancia Dealership as soon as possible if thewarning light either does not light up when the key is turned to MAR or if while
travelling the warning light switches on or flashes (along with a message and a symbol on the display on some versions). The operation of the
warning light may be checked by the traffic police using specific devices. Comply with the laws and regulations of the country where
you are driving.

Warning light What it means
GLOW PLUG HEATING/GLOW PLUG HEATING FAILURE (diesel versions)
Glow plugs
This warning light switches on when the key is turned to MAR. It will switch off as soon as the heater plugs
have reached a preset temperature.
The engine can be started as soon as the warning light switches off.
IMPORTANT At moderate or high ambient temperatures the warning light may stay on for an extremely
short time.
Glow plug preheating failure
The warning light flashes (together with a dedicated message and a symbol on the display on some
versions) to indicate a failure in the glow plugs preheating system.
Contact a Lancia Dealership to have the fault fixed as soon as possible.
WATER IN DIESEL FILTER (diesel versions)
The warning light remains on constantly when driving (together with a dedicated message and a symbol on
the display on some versions), to indicate the presence of water in the diesel fuel filter.
32)
WARNING
32)The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If thewarning light switches on, contact a Lancia Dealership as soon as possible for bleeding. If this problem is indicated immediately after
refueling, water may have entered the fuel tank. In this case, immediately turn off the engine and contact your Lancia Dealership.
55

Warning light What it means
DPF (PARTICULATE FILTER) CLEANING IN PROGRESS (Diesel versions with DPF)
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
The warning light (together with a dedicated message and a symbol on the display on some versions)
switches on constantly to notify the driver that the DPF system needs to eliminate captured pollutants
(particulate) through the regeneration process.
The warning light does not come on during every DPF regeneration, but only when driving conditions
require that the driver is notified. To switch the warning light off, the vehicle must be kept moving until the
regeneration process is completed. On average, the process lasts 15 minutes. Optimal conditions for
completing the process are achieved by travelling at 60 km/h with engine speed above 2000 rpm.
When this warning light switches on, it does not indicate a vehicle failure and thus it should not be taken to
a workshop. On some versions, together with the warning light switching on, the display shows a
dedicated message.
40)
WARNING
40)Vehicle travel speed should always be adapted to the traffic and weather conditions, and must always comply with traffic regulations. The
engine can be stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason, it is always advisable to wait for the warning light to go off before turning the engine
off, following the instructions appearing above. Do not complete the DPF regeneration process when the vehicle is stopped.

KNOWING THE INSTRUMENT PANEL

ACTIVE SAFETY
SYSTEMS
The car has the following active safety
systems:
ABS (Anti-lock Braking System);
EBD (Electronic Brake force
Distribution);
MBA (Mechanical Brake Assist);
ESC (Electronic Stability Control);
HH (Hill Holder);
ASR (Antislip Regulation);
BA (Brake Assist);
MSR (Motor Schleppmoment
Regelung);
For the operation of the systems, see
the following description.
ABS (Anti-lock Braking
System)
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the vehicle
can be controlled even during
emergency braking.IMPORTANT To obtain the maximum
efficiency of the braking system, a
bedding-in period of about 500 km is
needed: during this period it is better to
avoid sharp, repeated and prolonged
braking.
System intervention
The driver can feel that the ABS has
come into action because the brake
pedal pulsates slightly and the system
gets noisier: it means that the vehicle
speed should be altered to suit the type
of road surface.41) 42) 43) 44) 45) 46) 47) 48)
EBD (Electronic
Brakeforce Distribution)
SYSTEM
The EBD system allows the brake force
to be distributed between the front
and rear wheels.
MBA (Mechanical brake
assist) SYSTEM
This system (which cannot be
deactivated) recognises emergency
braking conditions according to the
speed of operation of the brake pedal
and provides an additional hydraulic
braking pressure to support that
provided by the driver. This allows
faster and more powerful operation of
the braking system.
49)
ESC (Electronic Stability
Control) SYSTEM
This is an electronic system that
controls vehicle stability in the event of
tyre grip loss, helping maintain
directional control.
The system is capable of recognising
potentially dangerous situations in
terms of the stability and intervenes
automatically on the brakes in a
differentiated manner for the four
wheels in order to provide a stabilising
torque.
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
System intervention
It is signalled by the flashing of theESC
warning light on the instrument panel,
to inform the driver that the car is in
critical stability and grip conditions.
50) 51) 52) 53) 54) 55)
HH (Hill Holder) SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
66
SAFETY

uphill:car stationary on a road with
a gradient higher than 5%, engine
running, brake pressed and gearbox in
neutral or gear (other than reverse)
engaged;
downhill:car stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and reverse
gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the torque
necessary for starting is reached, or
in any case for a maximum of 2
seconds, allowing your right foot to be
moved easily from the brake pedal to
the accelerator.
When the 2 seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage, the typical
mechanical brake release noise can be
heard, indicating that the car is about
to move.
IMPORTANT The Hill Holder system is
not active with engaged parking brake.IMPORTANT The Hill Holder system is
not a parking brake, therefore do not
leave the car without activating the
handbrake, switching off the engine,
and engaging first gear, with the car
parked in safe conditions.
IMPORTANT The Hill Holder system is
not active with engaged parking brake.
If the parking brake is engaged and
at the same time you press the brake
pedal, the Hill Holder system is
activated only if the parking brake is
disengaged before releasing the brake
pedal.
56)
ASR (AntiSlip
Regulation) SYSTEM
This is an integral part of the ESC
system and automatically operates in
the event of one or both drive wheels
slipping, loss of grip on wet roads
(aquaplaning) and acceleration
on slippery, snowy or icy roads, etc.
Depending on the slipping conditions,
two different control systems are
activated:
if the slipping involves both drive
wheels, the ASR intervenes reducing
the power transmitted by the engine;
if the slipping only involves one of
the drive wheels, it intervenes
automatically braking the wheel that is
slipping.
Turning the ASR system on/off
The ASR is switched on automatically
each time the engine is started.
While driving, the ASR can be switched
off and subsequently switched on
again by pressing the ASR OFF button
fig. 47.
On some versions, the intervention of
the system is indicated by a dedicated
message shown on the display.
When the system is not active, the LED
on the button ASR OFF turns on and,
on some versions, a message appears
on the display. When the ASR is
deactivated while driving, the next time
the car is started the ASR is
automatically activated.

When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the driving wheels skidding when
moving off gives you better traction.
57) 58) 60) 60) 61) 62)
BA (Brake Assist)
SYSTEM
The system, which cannot be turned
off, recognises emergency braking (on
the basis of the brake pedal operating
speed) and speeding up the response
of the braking system. The Brake Assist
device is deactivated if there is a ESC
system failure.
MSR (Motor
Schleppmoment
Regelung) SYSTEM
This system is an integral part of the
ABS that intervenes, if there is a
sudden downshifting, restoring torque
to the engine, thereby preventing
excessive drive at the drive wheels
which, especially in poor grip
conditions, could lead to a loss in
stability of the car.HBA (Hydraulic Brake
Assist) SYSTEM
It is an integral part of the ESC system.
The HBA system is designed to
improve the car’s braking capacity
during emergency braking.
The system detects an emergency
braking by monitoring the speed and
strength with which the brake pedal
is pressed, thereby applying the optimal
brake pressure. This can reduce the
braking distance: the HBA system
therefore completes the ABS.
Maximum assistance of the HBA
system is obtained pressing the brake
pedal very quickly; in addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to obtain benefits
from the system.
Do not reduce pressure on the brake
pedal until braking is no longer
necessary.
The HBA system is deactivated when
the brake pedal is released.
63) 64) 65) 66)
WARNING
41)The ABS gets the most from the
available grip, but it cannot improve it; you
should therefore take every care when
driving on slippery surfaces and not take
unnecessary risks.
42)When the ABS cuts in and you feel the
brake pedal pulsating, do not remove
your foot, but keep the pedal pushed
down; in doing so you, will stop in the
shortest distance possible under the road
conditions at the time.
43)If the ABS system intervenes, this
indicates that the traction of the tyres on
the road is nearing its limit. You must slow
down to a speed compatible with the
available traction.
44)The ABS cannot overrule the natural
laws of physics, and cannot increase
the grip available according to the
condition of the road.
45)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
46)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
47)For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.

ASSISTANCE
SYSTEMS
iTPMS System (indirect
Tyre Pressure
Monitoring System)
(for versions/markets, where provided)
67) 68) 69) 70) 71) 72)
The car can be equipped with the
iTPMS (indirect Tire Pressure
Monitoring System) which monitors the
tyre inflation status thanks to wheel
speed sensors.
The system warns the driver if one or
more tyres are flat by the
warning
light continuously lit on the instrument
panel and a dedicated warning
message on the display.
If one tyre only is flat, the system can
indicate its position: it is in any case
recommended to check the pressure
on all four tyres.
The system does not recognise the tyre
pressure value, but it is able to indicate
if the pressure of one or more tyres
falls below a certain pressure threshold.
This indication is displayed also when
turning the engine off and on again until
the RESET procedure is carried out.Reset procedure
The iTPMS needs an initial "self-
learning" phase (with length depending
on the driving style and road conditions:
optimal conditions being driving on a
straight road at 80 km/h for at least 20
minutes) which starts when the Reset
procedure is carried out.
The Reset procedure must be carried
out:
each time tyre pressure is modified;
when even only one tyre is changed;
when tyres are rotated/inverted;
when the space-saver wheel is
fitted.
Before carrying out the Reset
procedure, inflate the tyres to the rated
pressure values specified in the inflation
pressure table (see "Wheels" paragraph
in the "Technical specifications"
chapter).
If the Reset procedure is not carried
out, in all above cases, the
warning
light may give false indications on
one or more tyres.
To carry out the RESET procedure, with
the car stopped and the ignition device
at MAR, use the Main Menu as follows:
briefly press thebutton: the
display will show Reset;
press thebutton or the
button to select ("Yes" or "No");
briefly press thebutton: the
display will show "Confirm";
pressbutton orto select
("Yes" to Reset or "No" to exit the video
page);
press thebutton again to return
to the standard screen or to the main
menu according to where you are in the
menu.
At the end of the Reset procedure the
display will show the "Reset saved"
message, indicating that the self-
learning has been started and you will
hear an acoustic warning beep.
If the iTPMS self-learning is not properly
executed, the message is not
displayed, and no beep is heard.
Operating conditions
The system is active for speeds above
15 km/h.
In a few situations such as sporty
driving, particular conditions of the road
surface (e.g. icy, snowy, unsurfaced
roads...) the signalling may be delayed
or partial in detecting the contemporary
deflation of more than one tyre.
