2015 Alfa Romeo 4C engine

SBR SYSTEM (Seat
Belt Reminder)
IN BRIEF
This system comprises an acoustic
warning which, in conjunction with
the
warning light flashing on the
instrument panel, advises the driver if
their seat belt has not been fastened.
Contact the dedicated Alfa Romeo
Dealership to deactivate this acoustic
warning permanently.
The acoustic warning can be
reactivated at any time through the
Setup Menu (see "Menu Options"
paragraph in “Knowing the
instrument panel” section).
If the driver side seat belt is not
fastened, when 20 km/h is exceeded or
when travelling at a speed from 10 to
20 km/h for longer than 5 seconds, an
acoustic signal sequence will be started
(continuous acoustic signal for the first
6 seconds followed by 90 seconds
of intermittent beeping) and the
warning light will flash.The warning light will stay on constantly
at the end of the cycle until the engine
is stopped. The acoustic signal is
interrupted immediately when the seat
belt is fastened.
If the seat belt is unfastened again
when driving the car, the acoustic signal
and the flashing warning light resume
as described previously.
PRETENSIONERS
The car is equipped with seat belt
pretensioners, which draw back the
seat belts by several centimetres in the
event of a strong frontal impact. This
guarantees the perfect adherence
of the seat belts to the occupant's
bodies before the retention action
begins.
It is evident that the pretensioners have
operated when the belt withdraws
toward the retractor.
This car is also equipped with a second
pretensioner (in the kick plate area). Its
activation is signalled by the shortening
of the metal cable.
A slight discharge of smoke may be
produced during the activation of the
pretensioner which is not in harmful and
does not involve any fire hazard.
IMPORTANT To obtain the highest
degree of protection from the action of
the pretensioner, wear the seat belt
tight to the chest and pelvis.
94
SAFETY

79) If the car has been subject to
theft, attempted theft, vandalism,
or flooding, have the airbag
system inspected at a dedicated
Alfa Romeo Dealership.
80) The airbags may also be
deployed when the car is not
moving, if the key is inserted and
turned to MAR-ON 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
activate 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.
81) When the ignition key is turned
to MAR-ON, 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.
82) 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.83) The airbag does not replace seat
belts but increases their
effectiveness. 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.

STARTING AND DRIVING
Let’s get to the "heart" of the car:
seeing how you can exploit all of its
potential to the full.
We’ll look at how to drive it in any
situation, so that it can be a welcome
companion, with our comfort and
our wallets in mind.STARTING THE ENGINE ................104

STARTING THE
ENGINE
Procedure84) 85) 86)
❒press the brake pedal;
❒turn the ignition key to AVV and
release it as soon as the engine
starts.
IMPORTANT INFORMATION
8) 9)
❒If the engine does not start at the first
attempt, return the ignition key to
STOP before repeating the
procedure.
❒If, when the ignition key is at
MAR-ON, the
instrument panel
warning light stays on together with
the
warning light, turn the key
to STOP and then back to MAR-ON;
if the warning light stays on, try the
other keys provided with the vehicle.
If it is still not possible to start the
engine, contact a dedicated Alfa
Romeo Dealership.
❒Do not leave the ignition key at
MAR-ON when the engine is
stopped.WARMING UP THE
ENGINE JUST AFTER IT
HAS STARTED
Procedure
❒drive off slowly, letting the engine turn
at medium revs. Do not accelerate
abruptly;
❒do not demand full performance at
first. It is advisable to wait until the
digital engine coolant temperature
indicator starts moving.
SWITCHING OFF THE
ENGINE
Procedure
Turn the ignition key to STOP while the
engine is idling.10)
IMPORTANT After a demanding drive,
keep the engine idling for at least a
couple of minutes before stopping it, in
order to permit the temperature inside
the engine compartment to lower.
WARNING
84) It is dangerous to run the engine
in enclosed areas. The engine
takes in oxygen and releases
carbon dioxide, carbon monoxide
and other toxic gases.
85) The brake servo is not active
until the engine is started, so
you would need to apply much
more force than usual to the
brake pedal.
86) Do not start the engine by
pushing, towing or driving
downhill. These manoeuvres may
damage the catalytic converter.
IMPORTANT
8) It is advisable not to demand
maximum performance from your
car (e.g. excessive acceleration,
long distances at maximum rpm,
excessively intense braking, etc.)
when it is first used.
104
STARTING AND DRIVING

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").
74A0L0067
106
STARTING AND DRIVING

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 gearbox, the
system will not allow it. The system will
automatically downshift should the
engine reach the idling speed (e.g.
during deceleration). Using the DNA
system in "Natural" or "All Weather"
mode, it will automatically upshift if the
engine speed requires it.Automatic operation
(AUTO)
To activate/deactivate automatic
operation (AUTO) press theA/M
button on the transmission control
panel fig. 74; activation is signalled by
the wordAUTOon the display, next
to the gear engaged fig. 76.
InAUTOmode 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.

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 the1button
on the transmission control panel (or
the "+" steering wheel stalk) to engage
1st gear or theRbutton to engage
reverse.
When 1st gear is engaged, the system
sets itself toAUTOmode.
Neutral (N) can be engaged again by
pressing theNbutton with the brake
pedal pressed.
When the1,NorRbuttons 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.
