DISPLAY
The car is equipped with a display that,
according to the previously applied
settings, will show useful driving
information.
GEAR SHIFT INDICATOR
The GSI (Gear Shift Indicator) system
advises the driver to change gear
through a specific indication 5 fig. 29, 30
on the instrument panel.
Through the GSI, the driver is notified
that the gear change will allow a
reduction in fuel consumption.
Therefore, for driving oriented towards
reducing fuel consumption, it is advisable
to stick to “Natural” or “All Weather”
mode and to follow the suggestions of
the Gear Shift Indicator, where traffic
conditions permit.
When the () icon is displayed on the
instrument panel, the GSI suggests
switching to a higher gear, while when
the () icon is displayed, the GSI
suggests shifting to a lower gear.
IMPORTANT The GSI is not active when
the transmission is operating in AUTO
mode.
The indication in the instrument panel
remains on until the driver shifts gear or
the driving conditions go back to a
situation where gearshifting is not
required to improve consumption.

TCT TWIN CLUTCH
TRANSMISSION
Alfa 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. 43
are pressed, irrespective of the pressure
applied to the brake pedal.
43A0L0067
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
(ignition-operated electrical services
activated), the screen displays the gear
engaged and the active operating mode
(automatic = AUTO or manual = no
display).
OPERATING MODE
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
ratio 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”).
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.

71
The system will automatically downshift
should the engine reach the idling speed
(e.g. during deceleration).
Using the DNA system in “Normal” mode,
it will automatically upshift if the engine
speed requires it.
Automatic operation (AUTO)
To activate/deactivate automatic
operation (AUTO) press the A/M button
on the transmission control panel fig. 43;
activation is signalled by the word AUTO
on the display, next to the gear engaged
fig. 45.
45A0L0068
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.
SHIFT PADDLES
These enable sequential gear shifting
fig. 46.
❒ shift paddle “+” (pulling paddle
towards driver, see fig. 47): shift up;
❒ shift paddle “–” (pulling paddle
towards driver, see fig. 47): shift down.

STARTING AND DRIVING
72
The shifting up or down is only permitted
if the engine revs allow it.
STARTING THE ENGINE
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 1 button on the
transmission control panel (or the “+”
steering wheel stalk) to engage 1st gear
or the R button to engage reverse.
When 1st gear is engaged, the system
sets itself to AUTO mode.
Neutral (N) can be engaged again by
pressing the N button with the brake
pedal pressed.
When the 1, N or R buttons 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 notes
To start in presence of a gearbox fault
(see “Warning lights and messages”
paragraph in the “Knowing the instrument
panel” chapter), run the
“Delayed start-up” procedure:
turn the key to the AVV position for at
least 7 seconds with the brake depressed
and the engine will start.
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).
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.
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 1 button 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 button R on the
gearbox panel;
❒ release the brake pedal and press the
accelerator pedal.
When reverse is engaged on some
versions, the system emits an acoustic
signal.
If the brake pedal is not depressed (and
the vehicle is stationary), the display will
show a dedicated message and the
system will automatically engage neutral
(N).
