Hill-start assist control
Hill-start assist control helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As hill-start assist control is initially disabled,
enable the system to make it operable. The enabled/disabled set ting
will be maintained the next time the engine is started.
The hill-start assist control ON
indicator will be illuminated
when system is enabled and
flash while the system is oper-
ating.
