Activating HDC
Once HDC is enabled it will activate automatically if
driven down a grade of sufficient magnitude (greater
than approximately 8%). The set speed for HDC is
selectable by the driver, and can be adjusted by using the
Electronic range switches located on steering column
shifter. The following summarizes the HDC set speed:

abled but will not activate

NOTE: During HDC the ERS +/- shifter input is used for
HDC target speed selection but will not affect the gear
chosen by the transmission. During HDC the transmis-
sion will shift appropriately for the driver-selected set
speed and corresponding driving conditions.
