2016 Alfa Romeo 4C brake light

ASR (AntiSlip
Regulation) SYSTEM
29) 30) 38) 39) 40)
This is an integral part of the ESC
system and automatically operates in
the event of one or both drive wheels
slipping, loss of grip on wet roads
(aquaplaning) and acceleration on
slippery, snowy or icy roads, etc.
Depending on the slipping conditions,
two different control systems are
activated:
if the slipping involves both drive
wheels, the ASR system intervenes,
reducing the power transmitted by the
engine;
if the slipping only involves one of
the drive wheels, it also intervenes
automatically, braking the wheel that is
slipping.
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 otherthan 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 increasingthe 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.
“ELECTRONIC Q2”
SYSTEM (“E-Q2”)
The "Electronic Q2" system intervenes
during acceleration on corners, braking
the inner drive wheel and thus
increasing the traction of the outer
wheel (which bears more of the car’s

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.
“Race” MODE
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.

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
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
Proceduredrive 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 temperatureindicator starts moving.
SWITCHING OFF THE
ENGINE
Procedure
Turn the ignition key to STOP while the
engine is idling.
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.9)When the engine is switched off never
leave the ignition device in the MAR
position to prevent useless current
absorption from draining the battery.
10)A quick burst on the accelerator before
stopping the engine serves 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. 75 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 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. 76 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.
