NOTE:
• During HDC the +/- paddle shifter input is used for
HDC target speed selection and will put the transmis-
sion into ERS but will not affect the gear chosen by the
transmission unless in Driver Override. During HDC
the transmission will shift appropriately for the driver-
selected set speed and corresponding driving condi-
tions.
• HDC performance is influenced by the Terrain Select
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness.
Driver Override:

brake application at any time. While in driver override
