Standard Cruise Control
WARNING
Do not use the cruise control system when
driving conditions do not permit maintaining a
constant speed, such as in heavy traffic or on
roads that are winding, icy, snow-covered,
slippery, or roads with a loose driving surface.
Failure to follow this precaution could cause a
collision or loss of vehicle control, possibly
resulting in personal injury or property damage.
NOTICE
When the cruise control is engaged, do not
attempt to shift gears without using the clutch
pedal. Failure to follow this precaution may result
in a temporarily uncontrolled increase in engine
speed. Transmission damage and gear stripping
could result.
NOTE: If the vehicle is equipped with a Detroit
DT12 automated transmission, setting the cruise
control with the engine brake on activates cruise
descent control mode. Moving the transmission
shift lever to the top position resumes the set
cruise speed. Moving the lever down to engage
the engine brake after the cruise control has
been set activates deceleration mode. See
‘Cruise Descent Control and Deceleration
Modes’ in this chapter.
In the ICUC, standard cruise control is operated by
three switches mounted in the right-hand switch pod
of the steering wheel. See Fig. 7.1.
