20)If, when the key is turned to MAR, the ¬warning light does not come on or if it stays on with the vehicle in motion (together with the
message on the display) there could be a failure in the safety systems; under these circumstances the airbags or pretensioners may not be
triggered in the event of an impact or, more rarely, they could be triggered accidentally. Before proceeding, contact a dedicated Alfa Romeo
Dealership to have the system checked immediately.
21)Failure of the
¬warning light is signalled by the flashing for longer than the usual 4 seconds of the “warning light. In addition, the airbag
system automatically disables the passenger side airbag. In this case, the ¬warning light may not indicate failures in the retaining systems.
Before proceeding, contact a dedicated Alfa Romeo Dealership to have the system checked immediately.
22)A failure of the
“warning light is indicated by the ¬warning light. In addition, the airbag system automatically disables the passenger
side airbag.
23)Deteriorated engine oil should be replaced as soon as possible after the digital warning light comes on, and never more than 500 km after it
first switches on. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember that when the
digital warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you must not top up the engine oil.
24)If the warning light flashes with the car in motion, contact the dedicated Alfa Romeo Dealership.
IMPORTANT
3)If, when the ignition key is turned to MAR, the warning light does not turn on or if it turns on constantly or flashes when travelling
(on certain versions, together with the message on the display), contact a dedicated Alfa Romeo Dealership as soon as possible.
WARNING
Page 56 of 156

SAFETY
54 The TPMS uses wireless devices with
electronic sensors mounted on the wheel
rims to constantly monitor the value of
tyre pressure.
The sensors mounted on each wheel as
part of the valve stem transmit various
information of the tyres to the receiver
module, in order to calculate the
pressure.
IMPORTANT Monitoring and maintaining
the correct pressure in all four tyres are
particularly important.
Tyre pressure monitoring system
low pressure warnings
43) 44) 45) 46) 47) 48) 49) 50) 51)
The system warns the driver if one or
more tyres are flat by switching on the
nwarning light constantly and by
displaying a dedicated messages.
In this case, stop the car as soon as
possible, check the inflation pressure of
each tyre and inflate to the cold tyre
pressure value prescribed for the car.
The system will automatically update
and after receiving the pressure update
the tyre pressure warning light switches
off.
You may need to drive the car for about
20 minutes at a speed higher than 20
km/h to allow the system to receive this
information.
32A0L0113
TPMS operation faults
The system fault is indicated by the
dedicated warning light
nwhich first
flashes for 75 seconds and then stays on
steadily. This can occur in any of the
following situations:
❒ Interference caused by electronic
devices or radio frequency emissions
similar to those of the TPMS sensors.
❒ Application of tinted films which
interfere with the signals of the radio
waves.
❒ Presence of snow or ice on the wheels
or the wheel arches.
❒ Use of snow chains.
❒ Use of wheels/tyres not equipped
with TPMS sensors.

SAFETY
56
43)The presence of the TPMS does not
permit the driver to neglect regular
checks of the tyre pressure, including for
the spare wheel.
44)Tyre pressure must be checked with
tyres rested and cold. Should it become
necessary for whatever reason to check
pressure with warm tyres, do not reduce
pressure even though it is higher than the
prescribed value. Repeat the check when
the tyres are cold.
45)Should one or more wheels be fitted
without sensors, the system will no longer
be available and, in addition to the TPMS
warning light flashing for less than one
minute before becoming constant, a
warning message will be shown on the
display, until 4 wheels with sensors are
fitted again.
46)The TPMS cannot warn of sudden
decreases in tyre pressure (for example
when a tyre bursts). In this case, stop the
car, braking with caution and avoiding
abrupt steering.
47)Replacing standard tyres with winter
tyres (and vice versa) requires TPMS
adjustment that must only be performed
by a dedicated Alfa Romeo Dealership.
IMPORTANT48)Changes in outside temperature may
cause tyre pressures to vary. The TPMS
system may temporarily indicate
insufficient pressure. In this case, check
the tyre pressure when cold and, if
necessary, restore the inflation values.
49)When a tyre is removed, it is
advisable to replace the rubber valve seal
as well: contact a dedicated Alfa Romeo
Dealership. Tyre and/or rim
fitting/removal operations require
specific precautions; to avoid damaging
or fitting the sensors incorrectly, tyre
and/or rim fitting/removal operations
should only be carried out by specialised
staff. Contact a dedicated Alfa Romeo
Dealership.
50)Strong radio-frequency interference
could inhibit the regular operation of the
TPMS. This condition will be indicated by
a message on the display. The message
will disappear automatically as soon as
the radio-frequency interference ceases
to affect the system.51)The tyre repair kit (“Fix&Go
Automatic”) provided with the car (where
provided) is compatible with the TPMS
sensors; using sealants not equivalent
with that in the original kit may adversely
affect its operation. If sealants not
equivalent with the original one are used,
it is recommended to have the TPMS
sensors checked by a qualified repair
centre.

61)Do not apply stickers or other objects
to the steering wheel or the passenger
side airbag cover. Do not place objects on
the passenger side of the dashboard
because these could interfere with the
correct opening of the passenger airbag
and cause injury to occupants.
62)Always drive keeping your hands on
the steering wheel rim so that the airbag
can inflate freely if necessary.
Do not drive with your body bent forward.
Keep your back straight against the
backrest.
63)Instructions for deactivating the
front passenger airbag can be found in
the “Menu Options” paragraph of the
“Knowing the instrument panel” chapter.
Please note that under these conditions
the airbag will NOT deploy when required
(accident).
64)Do not rest your head, arms or elbows
on the door to prevent injury during airbag
deployment.
65)Never lean head, arms or elbows out
of window.
IMPORTANT66)If the ¬warning light does not
switch on when the key is turned to MAR,
or stays on while driving (on some
versions, together with a message on the
display) there may be a fault in the
restraint systems. In this case, airbags or
pretensioners may not be activated in the
case of an accident or (in a lesser number
of cases) they may be activated
incorrectly. Before proceeding, contact a
dedicated Alfa Romeo Dealership to have
the system checked immediately.
67)Do not travel carrying objects on your
lap, in front of your chest or between your
lips (pipe, pencils, etc.): they could cause
severe injury if the airbag is deployed.
68) If the car has been subject to theft,
attempted theft, vandalism, or flooding,
have the airbag system inspected at a
dedicated Alfa Romeo Dealership.
69)The airbags may also be deployed
when the car is not moving, if the key is
inserted and turned to MAR even when
the engine is off, if the car is hit by
another moving vehicle. Also remember
that no safety device (airbags or
pretensioners) will be deployed in the
event of impact when the key is at STOP.
Non-deployment of these devices under
these circumstances does not therefore
indicate a system malfunction.70)When the ignition key is turned to
MAR, the
“warning light comes on
constantly for the first 4 seconds.
Then, if the warning light remains on, this
means the passenger’s protection has
been deactivated; if the warning light
switches off, instead, the passenger’s
protection is enabled.
71)The front airbag is designed to be
deployed for impacts of a greater
intensity than for the pretensioners. For
impacts whose intensity falls between
the two levels, normally, only the
pretensioners will be activated.
72)The airbag does not replace seat
belts but increases their efficiency.
Because front airbags are not deployed
for low-speed frontal impacts, side
collisions, rear shunts or rollovers,
occupants are protected only by their
seat belts, which must always be
fastened.

PARKING THE VEHICLE
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
❒ engage the gear (on a slope, engage
first gear if the vehicle is facing uphill or
reverse if it is facing downhill) and leave
the wheels steered;
❒ 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.
76)
IMPORTANT NEVER leave the car with
the transmission in neutral.
HANDBRAKE
To engage the handbrake, pull lever
1 fig. 42 upwards until the car is secured.
When the handbrake is engaged and the
ignition key is at MAR, the xwarning
light will switch on in the instrument
panel.
To release the handbrake, raise the lever
1 slightly, hold down button 2 and lower
the lever.
The xwarning light on the instrument
panel turns 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.
77)
IMPORTANT Carry out these
manoeuvres with the brake pedal
pressed.
42A0L0066
76)Never leave children unattended in
the vehicle. Always remove the key from
the ignition device when leaving the
vehicle and take it with you.
77)The car must be braked after a few
clicks of the handbrake: if this is not so,
contact the dedicated Alfa Romeo
Dealership to have it adjusted. Always
park the car safely as indicated by the
Highway Code and as described above.

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.
44A0L0146

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.
