"Low Cruise Control Speed Set Limit"
This parameter defines the lowest vehicle speed that will allow the cruise control to be set. Programming this parameter to the maximum value disables cruise control.
Table 1
Default Minimum Maximum
48 km/h (30 mph) 24 km/h (15 mph) 204 km/h (127 mph) "High Cruise Control Speed Set Limit"
This parameter defines the highest vehicle speed that will allow the cruise control to be set. If a driver attempts to set a vehicle speed higher than this limit, the high cruise control set limit will be the cruise set speed. If this parameter is programmed to a value that is greater than the "Vehicle Speed Limit" parameter, the cruise control switches can be used to exceed the programmed vehicle speed limit.

Default Minimum Maximum
121 km/h (75 mph) 48 km/h (30 mph) 204 km/h (127 mph) "Engine Retarder Mode"
This parameter determines the operation of the "Auxiliary Retarder Output" and the "Exhaust Retarder Output" while the cruise control on/off switch is in the ON position, but the engine is not in cruise control. This feature does not determine, and the feature does not allow the operation of the retarder while the engine is in cruise control.When this parameter is programmed to "Coast", the retarder is enabled only while the service brakes are being applied. The retarder operates with the application and the release of the service brake in the coast mode.When this parameter is programmed to "Latch", the retarder stays enabled after the service brakes are released. A direct, immediate pressure on the brake pedal latches the retarder in the ON position. The retarder remains enabled until the accelerator pedal is depressed.When this parameter is programmed to "Manual", the retarder operates independently of the cruise control status.

Manual Coast
Latch "Engine Retarder Minimum VSL Type"
This parameter provides two options for the operation of the engine retarder. The available options are "Soft Limit" and "Hard Limit". The default is "Hard Limit". Refer to Illustration 1.
Illustration 1 g01260986
Operation of the engine retarder as the vehicle speed falls below the "Engine Retarder Minimum Vehicle Speed".
"Engine Retarder Minimum Vehicle Speed"
This parameter determines the minimum vehicle speed limit for the engine retarder to turn ON or to remain ON. Below this speed, the ECM will not turn ON the engine retarder unless the vehicle speed is zero.Programming this parameter to "0" allows the engine retarder to operate at all vehicle speeds. This parameter affects the engine retarder and any auxiliary retarder such as a BrakeSaver.

Default Minimum Maximum

This parameter defines the vehicle speed in kilometers per hour (km/h) or miles per hour (mph) above the cruise set speed when the engine retarder will be activated. The engine retarder switch must be in the ON position and the cruise control must be set for this feature to operate. This parameter affects the engine while the cruise control is activated.Programming this parameter to "0" disables this
