2015 Alfa Romeo 4C gearbox

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.

STARTING THE
ENGINE
Contact the dedicated Alfa Romeo
Dealership immediately if
warning
light stays on constantly on the
instrument panel.
JUMP STARTING
If the battery is flat, start the engine
using an auxiliary battery with the same
capacity or a little higher than the flat
one.
12)91)
Proceed as follows to start the car:
❒connect the positive terminals (+ sign
near the terminal) of the two batteries
with a jump lead fig. 79;❒with a second lead, connect the
negative terminal(−)oftheauxiliary
battery to an earthing point
on
the engine or the gearbox/
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
the 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.
IMPORTANT
12) Never use a fast battery charger
to start the engine as this could
damage the electronic systems
and the ignition and engine supply
control units.
WARNING
91) 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 lit cigarettes
away from the battery and do not
cause sparks.

DANGER OF FIRE.112) If a general protective fuse
(MAXI-FUSE, MEGA-FUSE,
MIDI-FUSE) blows, contact a
dedicated Alfa Romeo Dealership.
113) Before replacing a fuse, make
sure that the ignition key has
been removed and that all the
other services are switched off
and/or deactivated.

IN AN EMERGENCY

WARNING
115) Before towing, turn the ignition
key to MAR-ON 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 gearbox/
transmission is in neutral (N).
116) 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 car, you must
comply with all specific traffic
regulations, both in terms of the
towing device and behaviour
on the road. 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
screwed into the housing before
towing the car.117) The tow hook must be used
exclusively for roadside
assistance operations. 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
transport 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.
