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.

88) The car must be locked after afew 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
TRANSMISSIONThe 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. 74 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. With car stationary and key at MAR-ON
(ignition-operated electrical services
activated), the screen displays the gear
engaged and the active operating
mode (automatic =
AUTOor manual =
no display).
OPERATING MODES
The transmission can operate in two
operating modes (except when the
"Race" mode is selected):
❒ the first manual type (MANUAL), in
which the driver decides directly
when to change gear;
❒ the second completely automatic
(AUTO), in which the system decides
when to change gear.
When the "Race" mode is selected, the
only allowed operating mode is
MANUAL.
Manual operation
(MANUAL)
In this operating mode, the driver is
responsible for choosing the best gear
to engage, depending on the car
operating conditions.
Use the “+” steering wheel stalk to
engage a higher gear, or the “–” stalk to
engage a lower gear (see the following
paragraph, "Steering wheel stalks").74

If the request is accepted by the
system, the display shows the new
gear engaged.
If the request is not accepted by the
system, the display shows the gear
engaged before the request and emits
an acoustic signal.
If the gear change request may
adversely affect the correct operation of
the engine and the transmission, the
system will not allow it. The system will
also automatically change down if the
engine is idling (e.g. during
deceleration).Automatic operation
(AUTO)
To activate/deactivate automatic
operation (AUTO) press the
A/M
button on the transmission control
panel fig. 74; activation is signalled by
the word AUTOon the display, next
to the gear engaged fig. 76.
In AUTO mode the system changes
gear depending on the car speed, the
engine rpm and the intensity with which
the accelerator pedal is pressed.
To move the stationary car, 1st gear or
reverse (R) must always be engaged
(with brake pedal depressed). “Kick Down” function
The system also has the“Kick Down”
function: if necessary (e.g. when
overtaking), the system changes down
one or more gears when the
accelerator pedal is depressed beyond
the point where it becomes stiff (and
if the rpm allow it) in order to provide
suitable power and torque for the
acceleration requested by the driver.
When implementing the "Kick Down"
function, the system ensures varying
transmission management in
accordance with the selected DNA
mode.75

LEVERS ON THE
STEERING WHEEL
These enable sequential gear shifting
fig. 77.
– steering wheel stalk "+(pulling stalk
towards driver, see fig. 78): engage
higher gear;
– steering wheel stalk "– (pulling stalk
towards driver, see fig. 78): engage
lower gear. The engagement of a lower (or higher)
gear is only permitted if the engine
rpm allow it.
STARTING THE CAR
To start the engine press the brake
pedal: the system engages neutral (N)
automatically.
After the starting procedure, 1st gear
(1) or reverse (R) can be engaged.
Irrespective of the mode selected
(AUTO/MANUAL), to engage 1st gear
or reverse (R), it is necessary to press
the brake pedal and press the
1button
on the transmission control panel (or
the "+" steering wheel stalk) to engage
1st gear or the Rbutton to engage
reverse.
When 1st gear is engaged, the system
sets itself to AUTOmode.
Neutral (N) can be engaged again by
pressing the Nbutton with the brake
pedal pressed.
When the 1,Nor Rbuttons are
pressed (or "+" steering wheel stalk is
operated) without pressing the brake
pedal, no gear change request is
implemented by the system.
IMPORTANT Reverse cannot be
engaged by pressing the "-" stalk on
the steering wheel. Important information
If starting is requested with a
transmission failure (see "Warning lights
and messages" paragraph), carry out
the “Delayed start-up” procedure: when
the key is turned to AVV for at least 7
seconds with brake pedal pressed, the
engine will be started. The system will
remain in “recovery” condition.
If the engine does not start, contact a
dedicated Alfa Romeo Dealership.
When the driver's door is opened, the
system activates the hydraulic
components so that they are prepared
for the subsequent engine starting.
MOVING THE CAR
The car can set off both in 1st gear and
reverse (R).
Notes (concerning car
start-up)
The gears can only be engaged by
pressing the brake pedal. If the brake
pedal is not depressed, the display will
show a dedicated message.
It is not possible to set off in a higher
gear than 1st: if this is attempted,
the display shows a dedicated
message.77

When setting off on a medium-steep
incline, it is advisable to engage the
handbrake.
Engaging 1st gear
Proceed as follows:
❒press the brake pedal;
❒ press the 1button on the
transmission control panel;
❒ release the brake pedal and press
the accelerator pedal.
Engaging reverse (R)
Reverse (R) can only be engaged with
car stationary and brake pedal pressed.
Proceed as follows:
❒ press the brake pedal (car completely
stationary);
❒ press the R button on the
transmission control panel;
❒ release the brake pedal and press
the accelerator pedal. When reverse
is engaged, the system emits an
acoustic signal (for versions/markets,
where provided).
If the brake pedal is not depressed (and
the car is stationary), the display will
show a dedicated message and the
system will automatically engage
neutral (N). IMPORTANT With the car running, the
request is accepted and executed if the
car speed drops below 3 km/h within
3 seconds from the request: if the
request is not executed, the system will
maintain the gear engaged or, if the
speed of the car drops below 10 km/h,
will put the transmission in neutral (N)
and the manoeuvre will have to be
repeated.
ENGAGING NEUTRAL (N)
With car stationary and ignition key at
MAR-ON (irrespective of the condition
of the engine), neutral (N) can only
be engaged with the brake pedal
pressed.
If the car is in motion, neutral (N) can
always be engaged, irrespective of the
pressure applied to the brake and
accelerator pedals.
The display will show the letter
N
together with the active operating
mode.
With car in motion, to engage a gear
from the neutral (N) position, press the
1 button on the transmission control
panel (it is not necessary to press
the brake pedal): the transmission will
immediately engage the correct gear
according to the car’s speed. With car stationary and ignition key at
MAR-ON (irrespective of the condition
of the engine), 1st gear can only be
engaged with the brake pedal pressed.
LAUNCH CONTROL
The "Launch Control" strategy permits
high-performance starting.
This strategy can be activated with
vehicle at a standstill, Dynamic or Race
mode selected and 1st gear engaged.
The sequence of operations to perform
is as follows:
❒
press the brake pedal and hold it
down;
❒ press the accelerator pedal and hold
it down;
❒ press the "–" stalk behind the
steering wheel;
When the brake pedal is released, the
car will start with maximum
acceleration.
89)
To abandon the strategy, simply
interrupt the above sequence
of operations or release the accelerator
pedal.
