Metric Speed (km/h)
• Pushing the SET + button once will result in a 1 km/h increase in set speed. Each
subsequent tap of the button results in an increase of 1 km/h.
• If the button is continually pushed, the set speed will continue to increase in 10 km/h
increments until the button is released. The increase in set speed is reflected in the
instrument cluster display.
To Decrease Speed
While ACC is set, the set speed can be decreased by pushing the SET - button.
The driver's preferred units can be selected through the touchscreen radio settings if
equipped. Refer to "Understanding Your Instrument Panel" in your Owner's Manual on
www.dodge.com/en/owners/manuals for further details. The speed increment shown is
dependant on the chosen speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing 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 pushed, the set speed will continue to decrease in 5 mph
increments until the button is released. The decrease in set speed is reflected in the
instrument cluster display.
Metric Speed (km/h)
• Pushing 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 pushed, the set speed will continue to decrease in 10 km/h
increments until the button is released. The decrease in set speed is reflected in the
instrument cluster display.
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.
• The ACC system applies the brake down to 15 mph (24 km/h) when following a target
vehicle.
• The ACC system maintains set speed when driving up hill and down hill. However, a
slight speed change on moderate hills is normal. In addition, downshifting may occur
while climbing uphill or descending downhill. This is normal operation and necessary
to maintain set speed. When driving up hill and down hill, the ACC system will cancel
if the braking temperature exceeds normal range (overheated).
