In automotive engineering, a manettino dial is a rotary switch part of some modern Ferrari cars first designed by Frank Stephenson,[1] beginning with the Ferrari F430 in 2004. The adjustment dial is mounted on the steering wheel, usually just underneath the center of the wheel. The dial (Italian: manettino, lit.'little lever') is inspired by the controls found on F1 steering wheels, but have a more polished appearance.

The dial allows for the quick and simple adjustment of the electronics governing car suspension settings, traction control, electronic differential, and change speed of electronic gearbox.

A similar control system was employed on the Ferrari Enzo, but used individual buttons for different settings rather than a single rotary switch.
