To Decrease Speed
While ACC is set, the set speed can be decreased by
pressing the SET - button.
The speed decrement shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pressing the SET - button once will result in a 1 mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph.
• If the button is continually pressed, the set speed will
continue to decrease in 5 mph increments until the
button is released. The decrease in set speed is re-
flected in the DID.

Metric Speed (km/h)
• Pressing the SET - button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
• If the button is continually pressed, the set speed will
continue to decrease in 10 km/h increments until the
button is released. The decrease in set speed is re-
flected in the DID.
NOTE:
• When you override and push the SET + button or
SET - buttons, the new Set Speed will be the current
speed of the vehicle.
• When you use the SET - button to decelerate, if the
engine's braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
