Note: If Adaptive Cruise Control is Enabled, the minimum for
the Low Cruise Control Speed Set Limit is 30 MPH.
Advantages:
Programming of this parameter can restrict the use of
cruise control to those places where it is proper.
Disadvantages:
If the Low Cruise Control Speed Set Limit is set too low
it may allow drivers to operate the cruise in slower city
traffi c, which may not be desirable. However, if LCC is
set too high, the driver will not be able to use it when
climbing long grades.
Recommendations:
✔ A typical value for Low Cruise Control Speed Set
Limit is 30 MPH (48 km/h).
