OPERATING INSTRUCTIONS - 5

NOTE: Depressing and holding the Speed (+)/(-) switch
for 3 seconds or longer will cause the speed to slowly
ramp up ((+)/Res) or down (-). Release the switch when
the desired speed is achieved, this will be the new set
speed.
CANCELLING THE CRUISE SET-POINT
1. Press the Speed Cancel switch.
2. Pull the throttle handle back below the set point.
3. The Cruise Lamp will go OFF indicating that the
operator has full throttle control over the engine.
IMPORTANT: The ECM 'remembers' the previous
set point of a Cruise Mode operation. This means that
you may have two set points in memory, one for MPH
Mode and one for RPM Mode. ONLY the Cruise speed
set-point for the current cruise mode (MPH or RPM)
has been cancelled. At this point, a new set speed
could be selected, you may use the Resume Mode to
go back to the previous set speed, or you could change
cruise mode and use Resume or Set Speed in the newly
selected cruise mode.
RESUME MODE
1. After cancelling a Cruise Mode set speed, the
previous set speed can be resumed by pressing
the Speed (+)/Res switch, then pushing the
throttle handle forward above the previous Cruise
set-point.
NOTE: The operator may disengage Cruise Mode at
any time by pulling the throttle handle back below the set
point. The Cruise lamp will fl ash indicating that Cruise
Mode is still requested, but not engaged. If the throttle
handle is pushed forward past the previous set-point,
while the Cruise lamp is blinking, Cruise will Resume
at the previous set-point, and the Cruise lamp will be
steady ON.
EXITING CRUISE MODE
1. Press the MPH/RPM switch to OFF.
2. The Cruise Lamp will go OFF. Cruise mode
will remain engaged until the operator pulls the
throttle handle back below the set point.
IMPORTANT:
It is good practice to always exit
Cruise Mode properly, prior to shutting off the
engine. If the engine is turned off while the Cruise
Mode switch is in MPH or RPM Mode, the ECM is
still being commanded to be in the Cruise mode.
The ECM remembers the last set speed for each
cruise mode and the last switch command prior to
being shut off. When the engine is re-started, Cruise
Mode will be resumed. If Speed Cancel was the last
operation prior to turning the engine off, the Cruise

Lamp will be off. If the operator simply pulled the
throttle back to neutral and shut off the engine while
cruise mode was engaged, the Cruise Lamp will be
blinking and as the throttle handle is pushed forward
past the previous set point, cruise would resume.
If the Cruise lamp is fl ashing when you re-start
the engine, simply press the Speed Cancel switch,
or turn the Cruise Mode switch OFF, to regain full
throttle control .
The ECM remembers the last programmed Cruise
speed, even if the Speed Cancel switch has been
pressed. If you wish to resume Cruise Mode at
the previously selected speed, select the desired
cruise mode (MPH or RPM, if the switch is in the
OFF position), then press the Speed (+)/Res switch,
the Cruise Lamp will begin fl ashing and Cruise will
be engaged when the throttle handle passes the
previous set-point. Or, you may set a new Cruise
speed by pressing the Speed Set switch at the new
desired engine speed.
