Dodge 2008 Ram Pickup 3500 - Manual (Page 134)

Tapping the ACCEL button once will result in a 2 mph
(3km/h) speed increase. Each time the button is tapped,
speed increases so that tapping the button three times
will increase speed by 6 mph (10 km/h), etc.
Tapping the DECEL button once will result in a 1 mph (2
km/h) speed decrease. Each time the button is tapped,
speed will decrease. For example, tapping the button 3
times will decrease the speed by 3 mph (5 km/h), etc.
To decrease speed while the speed control is on, press
and hold the DECEL button. Release the button when the
desired speed is reached, and the new speed will be set.
To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE: When driving uphill, at elevations above 2,000
ft. (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. If the vehicle speed drops below 35 mph (56
km/h), the speed control will automatically disengage. If
this happens, you can push down on the accelerator
pedal to maintain the desired speed.
Vehicles equipped with a 6–speed manual transmission
should be operated in 4th or 5th gear under the above
conditions.
WARNING!
Speed Control can be dangerous where the system
can’t maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Don’t use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.
