Alfa Romeo 2015 4C Owner's Manual page 163

Neutral (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Always apply the
parking brake if you must leave the vehicle.
At engine startup, the transmission will automatically
select NEUTRAL (N) and AUTO mode. The brake pedal
must be pressed when starting the engine.
To select NEUTRAL (N) when the vehicle is stationary,
turn the ignition key to the MAR-ON position (engine
running or not), press the brake pedal, and press the N
button on the transmission gear selector.
When the vehicle is moving (with ignition ON), pressing
the NEUTRAL (N) button will engage N, regardless of
whether the brake pedal is pressed.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
With car in motion, to engage a gear from the NEUTRAL
(N) position, press the 1 button on the transmission
control panel (it is not necessary to press the brake pedal)
the transmission will immediately engage the correct
gear according to the car's speed.
