2016 Alfa Romeo 4C warning lights

ACOUSTIC SIGNAL
When reverse gear is engaged and
there is an obstacle behind the vehicle,
an acoustic signal is emitted which
varies according to the distance of the
bumper from the obstacle.
The frequency of the acoustic signal:
increases as the distance between
car and obstacle decreases,
culminating in a continuous acoustic
signal, when the distance is less than
approximately 30 cm;
decreases if the distance from the
obstacle increases, until the signal
ceases entirely;
remains constant if the distance
between car and obstacle remains
unchanged; if this situation concerns
the side sensors, the signal will stop
after approximately 3 seconds to avoid,
for example, indications in the event of
manoeuvres along a wall.
If several obstacles are detected by the
sensors, only the nearest one is
considered.
INDICATIONS ON
DISPLAY
(for versions/markets, where provided)
When the sensors are activated, the
screen in fig. 54 appears on the display.Obstacle presence and distance
information is therefore provided both
by the acoustic signal and the
instrument panel display.
The system indicates a detected
obstacle by displaying an arc in one or
more positions according to the
distance of the obstacle and its position
in relation to the car.
If an obstacle is detected in the rear
central area, the display shows all the
arcs in the rear central area, up to the
one that corresponds to the position of
the obstacle itself.
The signal is similar for obstacles in the
rear left or right area.
The arc that corresponds to the
position of the obstacle will flash.
The colour on the display depends on
the distance from and position of the
obstacle.
The car is close to the obstacle when
the display shows a single constant arcand emits a continuous sound.
If there are several obstacles, the
closest one is indicated.
FAULT INDICATION
Parking sensor failures, if any, will be
indicated when reverse is engaged by
the switching on of the
warning
light on the instrument panel together
with the message on the display (see
“Warning lights and messages”
chapter).
GENERAL WARNINGS
45)
4)
When parking, take the utmost care
over obstacles that may be above or
under the sensor.
Under certain circumstances, objects
close to the vehicle are not detected by
the system and could therefore cause
damage to the car or be damaged
themselves.
Some conditions may influence the
performance of the parking sensors:
the presence of ice, snow, mud or
multiple layers of paint on the sensor
surface may cause reduced sensitivity
of the sensor itself and therefore reduce
the system performance;
mechanical interference (e.g.
washing the car, rain, strong wind, hail)
may cause the sensor to detect a

tyre low pressure control warning lightswitches on constantly, the inflation
pressure must be adjusted until it
reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. You may
need to drive the car for about 20
minutes at a speed higher than 20 km/h
to allow the TPMS to receive this
information.
NOTE
The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
Therefore, the TPMS should not be
used as pressure switch while adjusting
the tyre inflation pressure.
Driving with insufficient tyre pressure
causes their overheating and can result
in tyre failure. The low inflation pressure
reduces fuel efficiency and tyre tread life
and may also affect handling and
braking performance of the car.
The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with a
suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
The TPMS warns the driver of any
condition of insufficient tyre pressure Ifthis drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in all
four tyres are particularly important.

The system warns the driver if one or
more tyres are flat by the dedicated
warning light
continuously on in the
instrument panel and by displaying
dedicated messages.In this case, stop the car as soon as
possible, check the inflation pressure of
each tyre and inflate to the cold tyre
pressure value prescribed for the car.
The system will automatically update
and after receiving the tyre pressure
update the tyre pressure control
warning light switches off. You may
need to drive the car for about 20
minutes at a speed higher than 20 km/h
to allow the system to receive this
information.TPMS operation faults
The system fault is indicated by the
dedicated warning lightwhich first
flashes for 75 seconds and then stays
on steadily. This can occur in any of the
following situations:
interference caused by electronic
devices or radio frequency emissions
similar to those of the TPM sensors.

WARNING LIGHTS AND MESSAGES
WARNING The warning light switches on together with a dedicated message and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to the
information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the
information in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults
are indicated by a repeated and prolonged warning "cycle". Less serious faults are indicated by warning "cycle" with a shorter
duration. The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause
of the malfunction is eliminated.

Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR-ON
the warning light switches on, but should switch off as soon as
the engine is started.
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.
If the warning light stays on or switches on when driving, it means
that the injection system is not working properly; in particular, if
the warning light comes on constantly, 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.
On some versions, the display shows the dedicated
message.
The warning light switches off if the malfunction
disappears, but it is still stored by the system.
Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the engine.
Prolonged use of the car with the warning light
on constantly may cause damage.
Contact the dedicated Alfa Romeo Dealership
as soon as possible.
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 the dedicated Alfa
Romeo Dealership as soon as possible.
