ESC (Electronic
Stability Control)
SYSTEM
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the car.

GETTING TO KNOW YOUR CAR

on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
Oversteer: occurs when the vehicle is
turning more than it should according
to the angle of the steering wheel.
Understeer: occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel
The ESC system also includes the
following systems:
ABS
EBD
CBC
DTC
ASR
HILL HOLDER
HBA
“ELECTRONIC Q2” (“E-Q2”)
"PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system activates automatically
when the engine is started and can only
be deactivated by selecting "Race"
mode. For more details, refer to the
"Alfa DNA system" paragraph in this
chapter.
SYSTEM INTERVENTION
This is indicated by the flashing of thewarning 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.

EBD FAILURE
The simultaneous switching on of the
(red) and
(amber) warning lights with the engine on, indicates
either a failure of the EBD system or that the system is
not available. In this case, the rear wheels may suddenly
lock and the vehicle may swerve when braking sharply.
The display shows the dedicated message.Drive very carefully to the nearest dedicated Alfa Romeo
Dealership to have the system inspected immediately.
redAIRBAG FAILURE
When the key is turned to MAR-ON, the warning light
switches on but should switch off after a few seconds.
The warning light stays on constantly if there is a fault in
the airbag system.
The display shows the dedicated message.
redSEAT BELTS NOT FASTENED
(for versions/markets, where provided)
The warning light switches on constantly with the car
stationary if the driver’s seat belt is not fastened.
The warning light flashes and a buzzer will sound if the
car is in motion and the driver’s seat belt is not correctly
fastened.For permanent deactivation of the SBR (Seat Belt
Reminder) system buzzer, contact the dedicated Alfa
Romeo Dealership. The system can be reactivated
using the Setup Menu.
WARNING
59)If thewarning light does not switch on when the key is turned to MAR or if it stays on when driving (together with the message on the
display), there may be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact a dedicated Alfa Romeo Dealership to have the
system checked immediately.

SEAT BELTS
USING THE SEAT BELTS
The belt should be worn keeping the
torso straight and rested against the
backrest. To fasten the seat belts, hold
the tongue A fig. 65 and insert it into
the buckle B, until it clicks into place.
On removal of the belt, if it jams, let it
rewind for a short stretch, then pull it
out again without jerking.
To unfasten the seat belts, press button
C and guide the seat belt with your
hand while it is rewinding, to prevent it
from twisting.
64)
The retractor may lock when the car is
parked on a steep slope: this is
perfectly normal. Furthermore, the
retractor mechanism locks the belt if it
is pulled sharply or in the event of
sudden braking, collisions or
high-speed bends.Alfa Romeo suggests: since the seat
belt can provide optimal protection if
the area on the abdomen is tight on the
body, after attachment it is advisable to
pull upwards the transversal part of the
belt, taking care not to twist it.
GENERAL
INSTRUCTIONS FOR
USING THE SEAT BELTS
Comply with (and make sure all car
passengers follow) the local laws in
force regarding the use of seat belts.
Always fasten the seat belts before
setting off.
Seat belts must also be worn by
pregnant women: the risk of injury in the
event of an accident is reduced for
them and the unborn child if they are
wearing a seat belt.
Pregnant women must position the
lower part of the belt very low down so
that it passes over the pelvis and under
the abdomen fig. 66.The belt must not be twisted. The
upper part must pass over the shoulder
and cross the chest diagonally. The
lower part must adhere to the pelvis
fig. 67, not to the abdomen of the
occupant. Never use devices (clips,
clamps, etc.) to hold the seat belt away
from your body.
65)
Each seat belt must be used by only
one person. Never travel with a child

SAFETY

PARKING
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
engage a gear (first gear if parked
uphill or reverse if facing downhill) and
leave the wheels turned;
stop the engine and engage the
handbrake.
Block the wheels with a wedge or a
stone if the car is parked on a steep
slope.
Wait until the indication of the gear
engaged disappears on the display
before releasing the brake pedal.
87)
IMPORTANT:NEVERleave the car with
the gearbox in neutral.
HANDBRAKE
To engage it, pull lever A
fig. 75 upwards until the car is secured.
When the handbrake is engaged and
the ignition key is at MAR-ON, the
warning light will switch on in the
instrument panel.
To release the handbrake, raise lever A
slightly, hold down button B and lower
the lever. The
warning light in the
instrument panel will switch off.
Four or five clicks are generally enough
when the car is on level ground, while
ten or eleven may be required if the car
is on a steep slope and laden.
88)
IMPORTANT Carry out these
manoeuvres with the brake pedal
pressed.
WARNING
87)Never leave children unattended in the
car. Always remove the key from the
ignition when leaving the car and take it
with you.
88)The car must be locked after a few
clicks of the parking brake: if this is not so,
contact the dedicated Alfa Romeo
Dealership to have it adjusted. Always park
the vehicle safely as indicated by the
Highway Code and as described above.
USING THE
TRANSMISSION
The 4C features the TCT 6-speed twin
dry clutch transmission with steering
wheel controls. This is an advanced
technical solution which combines the
control of a manual gearbox, the
immediacy of a sequential system and
the convenience of being able to select
an automatic selection programme
without the slowdown of a conventional
automatic transmission.
With the key removed from the ignition,
the system will not implement any
action when the buttons on the
transmission control panel on the
central tunnel fig. 76 are pressed,
irrespective of the pressure applied to
the brake pedal. Therefore, the
transmission will remain in the condition
that it was in when the engine was
switched off.

96
STARTING AND DRIVING

5 = fifth gear;
6 = sixth gear;
R = reverse.
The car always starts in neutral. When
1st gear is requested, the system
forces the selection ofAUTOmode.
IMPORTANT If 10 seconds elapse with
the ignition key in theMAR-ON
position and the display does not show
the gear engaged, turn the key to the
STOPposition, wait for the display to
switch off and then repeat the
procedure. If the fault persists, contact
a dedicated Alfa Romeo Dealership.
ACOUSTIC SIGNAL
For safety reasons, an acoustic signal is
emitted when the car is parked with the
transmission in neutral (N) (the signal
can be heard when the ignition key is
turned toSTOP).
With the car stationary, the engine
started and (1st) gear or (R) engaged,
the system activates the acoustic signal
and automatically places the
transmission in neutral (N) when:
the accelerator and/or brake pedal
are not operated for at least 3 minutes;
the brake pedal is pressed for longer
than 10 minutes;
the driver's door is opened and the
accelerator pedal or the brake pedal are
not operated for at least one and a half
seconds;
a fault has been detected in the
transmission.
PARKING THE CAR
When parking and leaving the car,
proceed as follows:
engage a gear (1st gear if facing
uphill or reverse if facing downhill) and
leave the wheels turned;
stop the engine and engage the
handbrake.
Block the wheels with a wedge or a
stone if the car is parked on a steep
slope.
Wait until the indication of the gear
engaged disappears on the display
before releasing the brake pedal.
IMPORTANT:NEVERleave the car with
the transmission in neutral.
GENERAL WARNINGSWith car stationary and gear
engaged, always keep the brake pedal
pressed until you decide to set off, then
release the brake and accelerate
gradually.
During prolonged stops with the
engine running, it is advisable to keep
the transmission in neutral (N).
In order to safeguard the efficiency of
the clutch, do not use the accelerator
to keep the car stationary (e.g. when
stopped on an incline). The clutch could
overheat and be damaged: use the
brake pedal or the handbrake and onlyoperate the accelerator pedal when you
decide to set off.
If, with reverse gear (R) engaged,
you have to engage 1st gear or vice
versa, only do this when the car is
completely stationary and with the
brake pedal pressed.
If it is necessary to proceed downhill
with transmission in neutral (N) for
unexpected reasons, bearing in mind
that this practice is highly inadvisable,
remember that when gear engagement
is requested, the system will
automatically engage the best gear to
permit the correct transmission of drive
torque to the wheels, according to the
speed of the car.
When necessary, it is possible to
engage 1st gear, reverse (R) or neutral (
N) with the engine off, the key at
MAR-ON and the brake pressed. In this
case, change gear leaving at least 5
seconds between one gear change and
the next, in order to safeguard the
operation of the hydraulic system, and
the pump in particular.
For uphill departures, it is advisable
to accelerate gradually but fully
immediately after releasing the
handbrake or the brake pedal; this
allows the engine to temporarily
increase the number of revs and tackle
the steepest gradients with more torque
at the wheels.
