SYSTEM OPERATION
Cruise SET/RESUME Switch is released, then the cruise
system automatically re-engages.
To engage and disengage the cruise control system, proceed
as follows:
1. While riding in fourth, fifth, or sixth gear, turn the Cruise
ON/OFF Switch to the ON position. See Figure 4-61. The
switch is located on the fairing cap of FLHTCU models,
the instrument nacelle of FLTR models, and the left
handlebar lower switch housing on FLHRC models. The
Cruise Enabled/Engaged lamp in the tachometer face
(speedometer on FLHRC models) turns orange to indicate
that the system is activated. See Figure 4-63. An orange
lamp in the switch on both FLHTCU and FLTR models
also indicates this condition to the rider.
2. With the motorcycle traveling at the desired "cruise" speed,
30-85 MPH (48-137 km/h), momentarily push the Cruise
SET/RESUME switch to SET. See Figure 4-62.
3. The ECM "reads" the Vehicle Speed Sensor (VSS) to
establish the desired vehicle speed. The ECM then mod-
ulates the throttle control actuator to maintain vehicle
speed. The Cruise Enabled/Engaged lamp in the tacho-
meter face (speedometer on FLHRC models) turns from
