GRAPHICAL INDEX

37) For the correct operation of the
ABS, 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=DynamicorRace(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).

DRIVING MODES
Lever A is monostable type. In other
words, it always remains in a central
position.
The selected driving mode is indicated
by the corresponding LED switching
on in the panel and by an indication on
the display.
“Natural” MODE
ESC and ASR systems:intervention
thresholds aimed at providing comfort
and safety in normal grip and driving
conditions.
"Electronic Q2" system:the system
is calibrated to ensure the best driving
comfort.
Engine and gearbox/transmission:
standard response.“Dynamic” MODE
Activation
Move the lever A fig. 47 upwards (to the
letter “d”) and hold in this position for
half a second, until the corresponding
LED lights up and the "Dynamic" mode
activation indicator appears on the
display.
When "Dynamic" mode is activated, the
turbocharger pressure (bar) and engine
oil temperature (°C) screen is displayed
automatically fig. 49:
When released, lever A will return to the
central position.
ESC and ASR systems:intervention
thresholds that ensure more enjoyable,
sportier driving whilst guaranteeing
the stability of the car."Electronic Q2" system:the system
is calibrated to increase traction whilst
accelerating on bends, improving
the agility of the car.
Engine and gearbox/transmission:
adoption of sports mapping.
IMPORTANT In "Dynamic", the
sensitivity of the accelerator pedal
increases considerably. Consequently,
driving is less fluid and comfortable.
Deactivation
To deactivate “Dynamic” mode and
return to “Natural”, move lever A fig. 47
downwards (to letter “a”) and keep it
in this position for half a second. In this
case, the LED corresponding to
“Natural” mode will light up and the
“Natural” mode activation indication will
appear on the display.

Activation
Move the lever A fig. 47 upwards (to the
letter “d”) and hold in this position for
5 seconds, until the "Race" mode
activation indicator appears on the
display. When "Race" mode is
activated, the longitudinal/lateral
accelerometer indicator screen
(G-meter information) is displayed
automatically. This considers
gravitational acceleration (G) fig. 50.
ESC and ASR systems:the systems
are deactivated in order to ensure
the fullest sensation of sport, leaving
the driver in full control of the vehicle.
When the vehicle is in unstable
conditions, the ESC reactivates
automatically when the brake pedal is
pressed until the ABS intervenes,
thus returning the vehicle to stable
conditions."Electronic Q2" system:the system
is calibrated to increase traction whilst
accelerating on bends, improving
the agility of the car.
Engine and gearbox/transmission:
adoption of sports mapping.
IMPORTANT In "Race", the sensitivity of
the accelerator pedal increases
considerably. Consequently, driving is
less fluid and comfortable.
IMPORTANT In "Race" mode the
transmission only works in MANUAL
mode. For further details, refer to the
"Using the transmission" section in
chapter "Starting and driving".
Deactivation
To deactivate "Race" mode and return
to "Dynamic", move lever A fig. 47
downwards (to letter “a”) and keep it in
this position for half a second. In this
case, the LED corresponding to
"Dynamic" mode will light up and the
"Dynamic" mode activation indication
will appear on the display.“All Weather” MODE
Activation
Move the lever A fig. 47 downwards (to
the letter “a”) and hold in this position
for half a second, until the
corresponding LED lights up and the
“All Weather” mode activation indicator
appears on the display.
ESC and ASR systems:intervention
thresholds aimed at ensuring maximum
safety in low-grip driving conditions. It
is advisable to select "All Weather"
mode in the presence of low-grip road
surfaces.
"ELECTRONIC Q2" SYSTEM: the
system is deactivated.
Engine and gearbox/transmission:
standard response.

Warning lights on
displayWhat it means What to do
redGEARBOX FAILURE
The digital warning light switches on when the
key is turned to MAR-ON, but it should switch off
after a few seconds.
The digital warning light flashes (together with a
message in the display and an acoustic signal) to
indicate that the gearbox/transmission is faulty.
The digital warning light can light up even in the
event of transmission overheating, after a
particularly demanding use. In this case an engine
performance limitation is performed.Contact the dedicated Alfa Romeo Dealership as
soon as possible.
If it is necessary to start the engine with a
gearbox/transmission failure, follow the procedure
described in the "Using the gearbox/
transmission" paragraph, "Starting the engine"
section in the "Starting and driving" chapter.

KNOWING THE INSTRUMENT PANEL

9) When the engine is off, do not
leave the ignition key turned to
MAR-ON to prevent unnecessary
electrical consumption from
draining the battery.
10) A quick burst on the accelerator
before turning off the engine
serves absolutely no practical
purpose; it wastes fuel and is
especially damaging to
turbocharged engines.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. 73
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 device 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. 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").
