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
paddle shifter. The following summarizes the HDC set
speeds:
• P = No set speed. HDC may be enabled but will not
activate.
• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
• 1st = 0.6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
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.
