detonation (knocking). The average of
both the MON (Motor Octane Number)
and ->RON (Research Octane Number)
is posted at the pump, also known as
ANTI-KNOCK INDEX.Multifunction display
Display field in the instrument cluster
used to present information provided
by the control system.
Multifunction steering wheel
Steering wheel with buttons for
operating the control system.
