2013 Alfa Romeo 4C warning light

System intervention
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.
HILL HOLDER SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
❒ uphill: car stationary on a road with a
gradient higher than 5%, engine
running, brake pressed and
transmission 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 engine
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 brake
disengagement noise, indicating that
the car is going to move imminently,
can be heard.
IMPORTANT The Hill Holder system is
not a parking brake; therefore, never
leave the vehicle without having
engaged the handbrake, turned the
engine off and engaged first gear,
so that the vehicle is parked in safe
conditions (for further information read
the "Parking" paragraph in the "Starting
and driving" chapter).
IMPORTANT There may be situations
on small gradients (less than 8%),
with vehicle laden, in which the Hill
Holder system may not activate,
causing a slight reversing motion and
increasing the risk of collision with
another vehicle or object. The driver is,
in any case, responsible for safe driving.
HBA (Hydraulic Brake
Assistant) SYSTEM
41) 42) 43)
The HBA system is designed to
improve the car’s braking capacity
during emergency braking. The system
detects emergency braking by
monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance, the HBA system therefore
completes the ABS.
Maximum assistance from 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 get the most
out of 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.

Deactivation
To deactivate “All Weather” mode and
return to “Natural”, move lever A fig. 47
upwards (to letter “d”) and keep it in
this position for half a second.
IMPORTANT
❒When the engine is next started, the
"All Weather" or "Dynamic" mode
selected previously is retained. The
system will reactivate in "All Weather"
or "Dynamic" mode, depending on
which mode was selected before the
engine was switched off.
❒ When the engine is next started, the
"Race" mode selected previously is
not retained. The system will
reactivate in "Dynamic" mode.
❒ It is not possible to go directly from
“Dynamic” mode to “All Weather”
mode and vice versa. You must
always first go back to “Natural”
mode and then select the other
mode.
System failure
In the event of system failure or a fault
with lever A fig. 47, no driving modes
can be selected. The display will become grey (same
screen as "Natural" mode) but without
an indication of the Alfa DNA setting.
The display will also show a warning
message.
EOBD SYSTEM
(European On
Board Diagnosis)Operation
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the
warning light on the instrument
panel, together with a message on
the display, when these components
are no longer in peak condition (see
“Warning lights and messages”
paragraph in the "Knowing the
instrument panel" chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
❒ monitor the efficiency of the system;
❒ indicate an increase in emissions;
❒ indicate the need to replace
deteriorated components.

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 arc
and 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.

TPMS (Tyre
Pressure
Monitoring System)(for versions/markets, where provided)
The car can be equipped with a tyre
pressure monitoring system (TPMS),
which informs the driver of the tyre
inflation status via dedicated messages
on the display fig. 55.
The system comprises a radio-
frequency transmitter sensor fitted to
each wheel (on the rim inside the tyre),
which is able to send information on the
inflation pressure of each tyre to the
control unit.IMPORTANT
INFORMATION ABOUT
THE TPMS
46) 47) 48) 49) 50) 51) 52) 53) 54)
The fault indications are not stored and
will therefore not be displayed after
the engine has been switched off and
then on again.
If the fault conditions persist, the control
unit will send the relative indications to
the instrument panel only after the
car has been in motion for a short time.
TPMS FAILURE
In the event of TPMS failure, dashes will
be displayed instead of the tyre
pressure status together with the
activation of the dedicated
warning
light (see "Warning lights and
messages" section in the"Knowing the
instrument panel" chapter). To restore
correct operation of the system,
contact a dedicated Alfa Romeo
Dealership.

WARNING
46) The presence of the TPMS doesnot permit the driver to neglect
regular checks of the tyre
pressure, including for the spare
wheel.
47) Tyre pressure must be checked with tyres rested and cold. Should
it become necessary for whatever
reason to check pressure with
warm tyres, do not reduce
pressure even though it is higher
than the prescribed value. Repeat
the check when the tyres are
cold.
48) Should one or more wheels be fitted without sensors, the system
will no longer be available and,
in addition to the TPMS warning
light flashing for less than one
minute before becoming constant,
a warning message will be shown
on the display, until 4 wheels
with sensors are fitted again. 49) The TPMS cannot warn of
sudden decreases in tyre pressure
(for example when a tyre bursts).
In this case, stop the car, braking
with caution and avoiding abrupt
steering.
50) Replacing standard tyres with winter tyres (and vice versa)
requires TPMS adjustment that
must only be performed by a
dedicated Alfa Romeo Dealership.
51) Changes in outside temperature may cause tyre pressures to vary.
The TPMS system may
temporarily indicate insufficient
pressure. In this case, check the
tyre pressure when cold and, if
necessary, restore the inflation
values.
52) When a tyre is removed, it is advisable to replace the rubber
valve seal as well: contact a
dedicated Alfa Romeo Dealership.
Tyre and/or rim fitting/removal
operations require specific
precautions; to avoid damaging or
fitting the sensors incorrectly,
tyre and/or rim fitting/removal
operations should only be carried
out by specialised staff. Contact
a dedicated Alfa Romeo
Dealership. 53) Strong radio-frequency
interference could inhibit the
regular operation of the TPMS.
This condition will be indicated by
a message on the display. The
message will disappear
automatically as soon as the
radio-frequency interference
ceases to affect the system.
54) The tyre repair kit (Fix&Go) provided with the car (for
versions/markets, where
provided) is compatible with the
TPMS sensors; using sealants not
equivalent with that in the original
kit may adversely affect its
operation. If sealants not
equivalent with the original one
are used, it is recommended to
have the TPMS sensors checked
by a qualified repair centre.
