To Vary The Speed Setting; Setting The Following Distance In Acc - RAM 2500 2020 Owner's Manual

210 STARTING AND OPERATING

TO VARY THE SPEED SETTING

To Increase Speed
While ACC is set, you can increase the set speed by
pushing the RES (+) button.
The speed increment shown is dependent on the cho-
sen speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•
Pushing the RES (+) button once will result in a
1 mph increase in set speed. Each subsequent tap
of the button results in an increase of 1 mph.
•
If the button is continually pushed, the set speed
will continue to increase in 5 mph increments until
the button is released. The increase in set speed is
reflected in the instrument cluster display.
Metric Speed (km/h)
•
Pushing the RES (+) 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 speed decrement shown is dependent on the cho-
sen 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 decrements 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 decrements
until the button is released. The decrease in set
speed is reflected in the instrument cluster display.
NOTE:
•
When you override and push the RES (+) button or
SET (-) button, 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 a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.
•
The ACC system maintains set speed when driving
uphill and downhill. However, a slight speed change
on moderate hills is normal. In addition, downshift-
ing may occur while climbing uphill or descending
downhill. This is normal operation and necessary to
maintain set speed. When driving uphill and down-
hill, the ACC system will cancel if the braking tem-
perature exceeds normal range (overheated).
SETTING THE FOLLOWING
DISTANCE IN ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (lon-
gest), three bars (long), two bars (medium) and one bar
(short). Using this distance setting and the vehicle
speed, ACC calculates and sets the distance to the
vehicle ahead. This distance setting displays in the
instrument cluster display.
Distance Setting
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
The system automatically defaults to the longest dis-
tance setting. To decrease the distance setting, push
the Distance Button and release. Each time the button
is pushed, the distance setting decreases by one bar.
Once the shortest setting is reached, if the button is
pushed again it will reset to the default setting
(longest).
