2020 Alfa Romeo 4C transmission

73
IMPORTANT With the car running, the
request is accepted and executed if the
car speed drops below 3 km/h within 3
seconds from the request: if the request
is not executed, the system will maintain
the gear engaged or, if the speed of the
car drops below 10 km/h, will put the
transmission in neutral (N) and the
manoeuvre will have to be repeated.
ENGAGING NEUTRAL (N)
With car stationary and ignition key at
MAR (irrespective of the condition of the
engine), neutral (N) can only be engaged
with the brake pedal pressed.
If the car is in motion, neutral (N) can
always be engaged, irrespective of the
pressure applied to the brake and
accelerator pedals.
The display will show the letter N
together with the active operating mode.To engage a speed from the neutral (N)
position, press button 1 on the gearbox
panel (it is not necessary to press the
brake pedal):
the gearbox will immediately choose the
correct gear according to the vehicle’s
speed.
With car stationary and ignition key at
MAR (irrespective of the condition of the
engine), 1
stgear can only be engaged with
the brake pedal pressed.
LAUNCH CONTROL
The “Launch Control” strategy permits
high-performance starting.
This strategy can be activated with
vehicle at a standstill, “Race” mode
selected and 1st gear engaged.
The sequence of operations to perform is
as follows:
❒ press the brake pedal and hold it
down;
❒ press the accelerator pedal and hold it
down;
❒ press the “–” paddle behind the
steering wheel;The car will start off at maximum
acceleration when the brake pedal is
released.
Keeping the accelerator pressed, the
system will automatically upshift once
the best engine speed has been achieved
for shifting gears.
78)
To abandon the strategy, simply interrupt
the above sequence of operations or
release the accelerator pedal.
DISPLAYED INFORMATION
When the key is turned to MAR-ON, after
about 1 second, the display shows the
transmission in neutral indication (N).
When driving, the display shows the gear
engaged and the active mode (AUTO or
MANUAL). The indications on the display
have the following meanings:
N = neutral;
1 = first gear;
2 = second gear
3 = third gear;
4 = fourth gear;
5 = fifth gear;
6 = sixth gear;
R = reverse.

STARTING AND DRIVING
74
The car always starts in neutral. When
1st gear is requested, the system forces
the selection of AUTO mode.
IMPORTANT If 10 seconds elapse with
the ignition key in the MAR position and
the display does not show the gear
engaged, turn the key to the STOP
position, wait for the display to go out
and then repeat the manoeuvre.
If the fault persists, contact a dedicated
Alfa Romeo Dealership.
ACOUSTIC SIGNAL
For safety reasons, there is a buzzer
warning when parking the car with the
gearbox in neutral (N) (the warning is
heard when the ignition key is turned to
the STOP position).
With the vehicle stationary, the engine
started and (1st) or (R) engaged, the
system activates the buzzer and
automatically put the gearbox in neutral
(N) when:
❒ the accelerator and/or the brake
pedal are not operated for at least 3
minutes;
❒ the brake pedal is pressed for longer
than 10 minutes;❒ the driver’s door is opened and the
accelerator pedal or the brake pedal are
not operated for at least 1.5 seconds;
❒ a fault is detected in the gearbox.
PARKING 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.
IMPORTANT: NEVER leave the car with
the transmission in neutral.
IMPORTANT NOTES
❒ With car stationary and gear engaged,
always keep the brake pedal pressed
until you decide to set off, then release
the brake and accelerate gradually.
❒ During prolonged stops with the
engine running, it is advisable to keep the
gearbox in neutral (N).❒ In order to safeguard the efficiency of
the clutch, do not use the accelerator to
keep the car stationary (e.g. when
stopped on an incline). Clutch overheating
could damage it:
use the brake pedal instead or the
handbrake and only press the accelerator
pedal when you wish to set off.
❒ If, with reverse gear (R) engaged, you
have to engage 1st gear or vice versa,
only do this when the car is completely
stationary and with the brake pedal
pressed.
❒ Although it is strongly discouraged, if
you are going downhill and for unknown
reasons you let the car move forward
with the gearbox in neutral (N), when
there is a request to engage a gear the
system will automatically engage the
best gear in relation to the speed of the
actual to allow the correct transmission
of the drive torque to the wheels;.

The device still remains active, without
the need to press the CANCEL/RESUME
button to return to the previous condition
once acceleration is concluded.
78) 79)
Automatic deactivation
The device is automatically switched off
in the following cases:
❒ if the ABS or ESC systems intervene;
❒ with vehicle speed under the
established limit; in case of fault to the
system.
STARTING AND DRIVING
76
RESTORING THE STORED SPEED
If the device has been deactivated, for
example by pressing the brake pedal, the
stored speed can be restored as follows:
❒ accelerate gradually until a speed
approaching the one stored is reached;
❒ engage the gear selected at the time
of speed memorising;
❒ press the CANCEL/RESUME button
(2 fig. 48).
INCREASING THE STORED SPEED
This can be done in two ways:
❒ by pressing the accelerator and then
storing the new speed reached;
or
❒ by moving the stalk upwards (+) until
the new speed, which will be stored
automatically, is reached.
Each operation of the stalk will
correspond to a slight increase in speed
(about 1 km/h), while keeping the stalk
upwards will correspond to a continuous
speed increase.
REDUCING THE STORED SPEED
This can be done in two ways:
❒ by deactivating the device and then
storing the new speed
or
❒ by moving the stalk downwards (–)
until the new speed, which will be stored
automatically, is reached.
Each movement of the stalk will
correspond to a slight reduction in speed
of about 1 km/h, while keeping the stalk
held downwards will decrease the speed
continuously.
DEACTIVATING THE DEVICE
The device can be switched off in the
following ways:
❒ by turning the ring nut 1 fig. 48 to
;
❒ by turning the engine off;
❒ by pressing the CANCEL/RESUME
button;
❒ by pressing the brake pedal or the
accelerator; in this last case the system is
not completely deactivated but gives
priority to the acceleration request.
79)When driving with device active, do
not press the “N” button on the
transmission control panel.
80)If operation of the device is faulty or
in the case of failure, turn ring nut
1 fig. 48 to
and contact a dedicated
Alfa Romeo Dealership.

❒ with a second cable, connect the
negative terminal (–) of the auxiliary
battery to an earthing point
Eon the
engine or the transmission of the car to
be started;
❒ start the engine; when the engine has
started, remove the leads, reversing the
order above.
If after a few attempts the engine does
not start, do not persist but contact a
dedicated Alfa Romeo Dealership.
IMPORTANT Do not connect the negative
terminals of the two batteries directly!
If the auxiliary battery is installed on
another car, check that there is no
accidental contact between metallic
parts of the two cars.
BUMP STARTING
Never, under any circumstances, jump
start the engine by pushing, towing or
coasting downhill.
FUEL CUT-OFF SYSTEM
OPERATION
This intervenes in the case of an impact
causing:
❒ the fuel supply cut-off with the engine
consequently switching off;
❒ automatic door lock release;
activation of all lights inside the car;
❒ the switching on of the hazard
warning lights.
The digital warning light and the
dedicated message on the display
indicate the intervention of the system.
Carefully check the vehicle for fuel leaks,
for instance in the engine compartment,
under the vehicle or near the tank area.
112)
111)This procedure must be performed
by qualified personnel as incorrect
actions may cause high-intensity
electrical discharge. Furthermore,
battery fluid is poisonous and corrosive:
avoid contact with skin and eyes. Keep
naked flames and lighted cigarettes away
from the battery and do not cause sparks.

113)Before towing, turn the ignition key
to the MAR position and then to STOP
without removing it. The steering column
will automatically lock when the key is
removed and the wheels cannot be
steered. Also check that the transmission
is in neutral (N).
114) When towing, remember that the
assistance of the brake servo is absent.
Consequently, more force is required at
the pedal in order to brake. Do not use
flexible cables when towing and avoid
jerky movements. Make sure not to
damage parts in contact with the car
while towing.
When towing the vehicle, you must
comply with all specific traffic
regulations and adopt an appropriate
driving behaviour.
Do not start the engine while towing the
car. Before tightening the ring, clean the
threaded housing thoroughly. Make sure
that the ring is fully fastened in the
housing before towing the vehicle.
IMPORTANT115) The tow hook should be used only
for emergencies on the road. You are
allowed to tow the vehicle for short
distances using an appropriate device in
accordance with the highway code (a rigid
bar), to move the vehicle on the road in
readiness for towing or transporting via a
breakdown vehicle.
Tow hooks MUST NOT be used to tow
vehicles off the road or where there are
obstacles and/or for towing operations
using cables or other non-rigid devices.
In compliance with the above conditions,
towing must take place with the two
vehicles (one towing, the other towed)
aligned as much as possible along the
same centre line.
