110 OPERATION
Effective August 11, 2008, a change was made to the Vehicle Electronic Control Unit
(VECU) software which affects the cruise control. As an added test to ensure that the service
brake switch is functional, the vehicle operator must press and release the brake pedal after
the engine has been started. This test verifies that the service brake switch is functioning.
The test also confirms that the cruise control will deactivate when the service brakes are
applied. If the brake pedal is not depressed after starting the engine, the cruise control
will not function. This change affects both newly manufactured vehicles, and vehicles on
which the VECU has been reprogrammed.
Note:
For vehicles manufactured prior to August 11, 2008 the VECU has been
reprogrammed.
Once the above conditions are satisfied, activate the cruise control as follows.
1 Move the Speed Control ON/OFF switch to the ON position.
2 At the desired road speed, press and release the SET switch. The vehicle will maintain at
the set speed.
Note:
Pressing the top of the Speed Control ON/OFF switch activates, or turns the switch
ON. Pressing the bottom of the switch deactivates, or turns the switch OFF.
Note:
To shift, simply disengage the clutch, change gears, then re-engage the clutch. Cruise
control will resume automatically if programmed to Auto Resume. When double clutching,
DO NOT bring the clutch pedal to the fully engaged position.
