Clutch Abuse Protection

p3 dm 15.05.007

Although a vehicle equipped with an UltraShift PLUS uses an automated clutch, the clutch can still overheat and slip with improper use. The clutch abuse protection feature helps protect the clutch if the automated clutch starts to overheat. When the clutch abuse protection feature initiates and sounds a warning tone, full clutch actuation must be completed quickly. If it is not completed quickly enough, the system will either open the clutch (if the throttle pedal is not being pressed) or close the clutch (if the throttle pedal is being pressed). If the abuse continues, the system will open the clutch and take away throttle control briefly to allow the clutch to cool down.

To protect the clutch:

  • Select the lowest possible start gear for the application.

  • Use Creep Mode when appropriate.

  • Use the service brakes and the Hill Start Aid when launching on a grade.

  • Minimize the time it takes to engage the clutch from rest.

  • Do not use the throttle to hold the vehicle on a grade; use the service brakes.

  • Do not use the throttle to stop roll back on an incline after Hill Start Aid disengages; use the service brakes, and then relaunch.

  • Do not continually start and stop, especially when loaded; use a lower gear or Creep Mode.
