line as determined by a standardized
method. It is an indication of a gaso-
line’s ability to resist undesired detona-
tion (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.
SBC
(S
ensotronic B
rake C
ontrol)
Electronically controlled hydraulic
braking system for increased braking
safety and comfort.
