Cruise Control Parameters
Engine Retarder Minimum Vehicle Speed
Description:
Engine Retarder Minimum Vehicle Speed is similar to
Low Cruise Control Speed Set Limit. Engine Retarder
Minimum Vehicle Speed sets the minimum vehicle speed
at which retarder operation is allowed. This parameter
affects both the Engine Retarder Solenoids and any
auxiliary brake. Setting the Engine Retarder Minimum
Vehicle Speed to 0 (Zero) disables this feature.

Advantages:
The Engine Retarder Minimum Vehicle Speed
parameter turns the engine retarder off, at or below the
programmed speed. This parameter can also be used
to prevent excessive use of the engine retarder at low
speeds.
Disadvantages:
If the engine retarder is engaged and the truck slows
to the value of the Engine Retarder Minimum Vehicle
Speed the retarder will turn off.
Recommendations:
✔ Be sure to observe all federal, state, and local
ordinances regarding the use of the engine retarder
when setting the Engine Retarder Minimum Vehicle
Speed parameter.
