2012 Lancia Ypsilon brake light

ESC SYSTEM (Electronic Stability
Control)This is an electronic system that controls car
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
stabilizing torque.
The ESC system also includes the following
subsystems:
❒Hill Holder
❒ASR
❒Brake Assist
❒MSR
❒HBASYSTEM INTERVENTION
It is signalled by the flashing of theESCwarning
light on the instrument panel, to inform the driver
that the car is in critical stability and grip
conditions.
SYSTEM ACTIVATION
The ESC system switches on automatically when
the engine is started and cannot be switched off.
HILL HOLDER SYSTEM
This system is an integral part of the ESC system
and facilitates starting on slopes.
It is activated automatically in the following
instances:
❒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 braking pressure on the wheels until the
torque required for starting is reach or, in any
case, for a maximum of 2 seconds so that the right
foot can be moved easily from the brake pedal to
the accelerator pedal.
When 2 seconds have elapsed, without any
departure having taken place, the system is
automatically deactivated, gradually releasing the
braking pressure. During this release stage, a
typical mechanical brake release noise can
be heard, indicating that the car is about to move.
IMPORTANT The Hill Holder system is not a
parking brake, therefore do not leave the vehicle
without activating the handbrake, switching
off the engine and engaging first gear.
ASR SYSTEM (AntiSlip Regulation)
It is an integral part of the ESC system. It
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.Activation/deactivation of the ASR system
The ASR system activates automatically each time
the engine is started.
Whilst driving, the ASR can be deactivated and
subsequently activated again by pressing the ASR
OFF button fig. 70.
On some versions, the intervention of the system is
indicated by a 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 whilst 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, slipping of the drive wheels when
moving off makes it possible to obtain better
traction.

WARNING
For the ESC and ASR systems to
function correctly, all four tyres must,
above all, be the type, brand and size
prescribed, of the same brand and type, and
must be in excellent condition.
WARNING
The ESC functions even when the
space-saver wheel is being used.
Always remember that the space-saver
wheel, being smaller than the original
wheel, provides less grip.
WARNING
Do not take unnecessary risks, even if
your vehicle is fitted with the ESC
and ASR systems. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is always
responsible for road safety.BRAKE ASSIST
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 SYSTEM
(Motor Schleppmoment Regelung)
This system is an integral part of the ABS, that
intervenes, if there is 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.

ENGINE STOPPING FAILURE CONDITIONS
When the system is active, due to comfort,
emission control and safety reasons, the engine
does not stop in some conditions, among which:
❒engine still cold;
❒especially cold outside temperature;
❒battery not sufficiently charged;
❒heated rear window activated;
❒windscreen wipers working at maximum speed;
❒particulate filter regeneration (DPF) in progress
(diesel engines only);
❒driver's door not shut;
❒driver's seat belt not fastened;
❒reverse gear engaged (for example, for parking
manoeuvres);
❒for versions equipped with automatic climate
control (for versions/markets, where provided),
if an adequate level of thermal comfort has
not been reached or with MAX-DEF activation;
❒during the first period of use, to initialise the
system.
If climate comfort is to be favoured, the
Start&Stop system can be disabled,
for a continuous operation of the
climate control system.ENGINE RESTARTING CONDITIONS
For reasons of comfort, to limit harmful emissions
and for safety purposes, the engine can restart
automatically without any action by the driver if
certain conditions are met, including:
❒battery not sufficiently charged;
❒windscreen wipers working at maximum speed;
❒reduced braking system vacuum (e.g. if the
brake pedal is pressed repeatedly);
❒car moving (e.g. when driving on roads with a
gradient);
❒engine stopping by Start&Stop system for over
3 minutes;
❒for versions equipped with automatic climate
control (for versions/markets where provided),
to enable suitable thermal comfort or with
MAX-DEF activation.
With gear engaged, automatic engine restarting is
possible only by fully depressing the clutch pedal.
The driver is informed by the displaying of a
message on the display and - for versions/markets,
where provided - by the flashing of the symbol

OPERATION WITH TRAILER
Sensor operation is deactivated automatically
when the trailer's electric cable plug is fitted into
the car's tow hook socket.
The sensors are automatically reactivated when
the trailer's cable plug is removed.
For correct operation, sensors must
always be clean from mud, dirt, snow
or ice. Be careful not to scratch or
damage the sensors while cleaning them.
Avoid using dry, rough or hard cloths. The
sensors must be washed using clean water,
with the addition of car shampoo if necessary.
When using special washing equipment such
as high pressure jets or steam cleaning, clean
the sensors very quickly keeping the jet more
than 10 cm away.
GENERAL WARNINGS
❒When parking, take the utmost care over
obstacles that may be above or under the
sensors.
❒Objects close to the car, are not detected under
certain circumstances and could therefore cause
damage to the car or be damaged.
The following conditions may influence the
performance of the parking sensor system:❒reduced sensor sensitivity and a reduction in the
parking assistance system performance could be
due to the presence on the surface of the sensor
of: ice, snow, mud, thick paint;
❒the sensor may detect a non-existent obstacle
(echo interference) due to mechanical
interference, for example when washing the car,
in rain (strong wind), hail;
❒the signals sent by the sensor can also be altered
by the presence of ultrasonic systems (e.g.
pneumatic brake systems of trucks or
pneumatic drills) near the vehicle;
❒parking assistance system performance can also
be influenced by the position of the sensors, for
example due to a change in the ride setting
(caused by wear to the shock absorbers,
suspension), or by changing tyres, overloading
the car or carrying out specific tuning
operations that require the car to be lowered.
WARNING
The driver is always responsible for
parking manoeuvres however. When
making these manoeuvres, always make sure
that no people (especially children) or
animals are present in your manoeuvring
area. The parking sensors are an aid for the
driver, but must never allow their attention
to lapse during potentially dangerous
manoeuvres, even those executed at low
speeds.

OPERATION
The assisted parking manoeuvre can only be
activated with the instrument panel on and at
speeds below about 30 km/h and consists of the
following stages:❒Activation:pressing the button
starts the
search.
❒Search:through side sensors, the system
continuously searches for a free parking space,
suitable for the car's dimensions. The driver
chooses on which side of the road they intend to
park using the direction indicators (if no
information is available from the direction
indicators or hazard warning lights, the search
takes place on the passenger side).
IMPORTANT The SEARCHING is disabled if,
after about 10 minutes, a suitable parking space
has not been found.
❒Identification:if the system identifies a free
parking space that is a suitable size for the
car, it signals its presence and indicates
the actions required for starting the manoeuvre.
❒Manoeuvre:the driver is asked to engage
reverse gear, release the steering wheel and
manage the accelerator, brake and clutch (in the
case of manual gearbox) or accelerator and
brake (in the case of automatic gearbox) (for
versions/markets, where provided). During the
reverse parking manoeuvre, the system manages
the steering wheel automatically. According to
the parking space, the manoeuvre may end
through reversing or further manoeuvres, both
in forward gear and in reverse, may be
necessary. After the first manoeuvre, when the
rear buzzer sounds continuously, the driver
is requested to disengage reverse and engage the
forward gear. If this is not enough, when the

Identifying a parking space
If the system identifies a suitable parking space
between two stationary vehicles or between other
obstacles (e.g. objects with an extensive side
surface such as vehicles, boxes, etc.) it will signal
that it has found a parking space that can be
entered fig. 83.
If the position reached is already suitable at the
beginning of the manoeuvre, the system will
advise the driver to engage reverse gear, otherwise
it will request further forward motion.
At the request to engage reverse gear the driver
should stop the car and engage reverse in order to
confirm the wish to start the manoeuvre. If the
driver continues driving, after about 10 metres the
system will no longer consider the parking space
identified and will start the search for new
suitable space.Manoeuvre
The driver controls the movements of the car
using accelerator pedal, brake and clutch (only on
versions with manual gearbox) whilst the system
automatically manages the steering system to
enter the parking space identified in the best
possible way.
During the manoeuvre it will be possible to take
advantage of the information coming from the
parking sensors (when reversing it is advisable to
reach the area where the rear sensors provide a
continuous tone signal), but it is always advisable
to keep an eye on the surrounding area.
The car can be stopped during the manoeuvre
and, whilst remaining stationary, reverse gear can
temporarily be released (for example, to allow a
pedestrian to pass through the area of the
manoeuvre).
The speed should be less than about 7 km/h
during the manoeuvre, otherwise the parking
manoeuvre will be interrupted.
If the driver carries out a voluntary or involuntary
action on the steering during the parking
manoeuvre (touching it or preventing its
movement), the manoeuvre will be interrupted.

INDEX

If the road surface is very uneven or there are
obstacles under the wheels affecting the movement
of the car, preventing it from continuing along
the correct trajectory, the manoeuvre may be
interrupted.
End of manoeuvre
If the size of parking space permits, the parking
manoeuvre may be performed in one manoeuvre.
When the reverse gear is disengaged the wheels
will be realigned and the manoeuvre will be
considered completed (the system will
consequently be deactivated).
If the size of the parking space is smaller, it may
take several manoeuvres: the driver will be
advised to complete the parking manoeuvre
manually via a dedicated message in the
instrument panel display.
WARNING
If you wish to stop the steering wheel
with your hands during a manoeuvre,
it is advisable to handle it firmly on the
outer rim. Do not try and keep your hands
on the inside or hold the spokes.GENERAL WARNINGS
❒The ultimate responsibility when parking,
however, always rests with the driver. During
these manoeuvres, always make sure that no
people, animals or objects are within the
manoeuvring area. The Magic Parking system
(like parking sensors) is designed to assist
drivers: in all cases, you must always pay the
utmost attention during potentially dangerous
manoeuvres, even when these are carried out
a low speed:
❒If the sensors undergo shocks influencing their
position, the system operation could be strongly
degraded.
❒If the sensors are dirty, covered by snow, ice or
mud or are repainted compared to the original
conditions, the system operation could be
strongly degraded. It is vital that the sensors are
always clean in order for the system to work
properly. During cleaning make sure not to
scratch or damage them; avoid using dry or
rough cloths. The sensors should be washed
using clean water with the addition of car
shampoo if necessary. In washing stations, clean
the sensors quickly, keeping the steam jet/high
pressure washing nozzles at least 10 cm away
from the sensors.
❒Ultrasonic sound sources (e.g. pneumatic brakes
of trucks or air drills) nearby could negatively
influence the sensor performance.
