2014 Alfa Romeo 4C engine

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.
ABS
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 car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.31) 32) 33) 34) 35) 36) 37)
System intervention
A slight pulsing of the brake pedal and
noise indicates the intervention of the
ABS: this is completely normal when
the system intervenes.
EBD SYSTEM
The EBD system is an integral part of
the ABS system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the vehicle, preventing sudden
locking of the rear wheels and
the consequent instability of the vehicle.
CBC (Cornering Brake
Control) SYSTEM
The system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the
inside of the corner (less affected by the
weight of the car) from locking,
ensuring better stability and direction
for the car. DTC (Drag Torque
Control) SYSTEM
This is an integral part of the ABS
system and intervenes in the case of
sudden downshifting, or during braking
when the ABS intervenes, restoring
torque to the engine and thus
preventing excessive drag at the drive
wheels, which may lead the wheels
to lock and a loss of car stability, above
all in low-grip conditions.
ASR (AntiSlip
Regulation) SYSTEM
29) 30) 38) 39) 40)
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 system intervenes,
reducing the power transmitted by
the engine;
❒ if the slipping only involves one of the
drive wheels, it also intervenes
automatically, braking the wheel that
is slipping.

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.

37) For the correct operation of theABS, 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.
38) The ASR system can’t overrule the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
39) The ASR system cannot prevent accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
40) The capability of the ASR system must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
41) The HBA system can’t overrule the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
42) The HBA system cannot prevent accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning. 43) The capability of the HBA system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise the safety of
the driver, the other occupants of
the car or any other road user.
“Alfa DNA” SYSTEM
(Dynamic car
control system)This device allows, using lever A fig. 47
(on the central tunnel), four car
response modes to be selected
according to driving style and road
conditions:
❒d=Dynamic orRace (sports driving
mode);
❒ n=Natural (mode for driving in
normal conditions);
❒ a=All Weather (mode for driving in
poor grip conditions, such as rain
and snow).
The device also acts on the dynamic
car control systems (engine,
gearbox/transmission, ESC system).47

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.

The car also has a connector, which
can interface with appropriate tools,
that makes it possible to read the error
codes stored in the electronic control
units together with a series of specific
parameters for engine operation and
diagnosis. This check can also be
carried out by the traffic control
authorities.
IMPORTANT After eliminating a fault, to
check the system completely, the
dedicated Alfa Romeo Dealership is
obliged to run tests and, if necessary,
road tests which may also require a
long journey.

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.
