OPERATING PROCEDURES Read all of this manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notices, Cautions, Warnings, and Dangers. Always bring the vehicle to a complete stop before shifting the direction selector. Do not take vehicle out of 'gear' while in motion (coast). Check the area behind the vehicle before operating in reverse. All occupants must be seated. Keep entire body inside vehicle and hold on while vehicle is in motion. TRUCOURSE TECHNOLOGY SYSTEM™ 4 General TruCourse Technology (TCT) system vehicles are operated in one of three modes or "performance options". All options have standard features that control, protect and diagnose the vehicle. The options are defined as follows: 1. The Golf Flat performance option: The motor's speed is sensed and regulated to 14.8 mph (23.8 kph) directly by the controller, the vehicle's flat ground speed will not change with different ground surfaces. The speed sensor also allows for precise control of the downhill vehicle speed during compression braking. As the vehicle crests a hill and begins to descend, the speed will be smoothly regulated to 14.8 mph (23.8 kph). This option is enabled when there is a blank plug installed. 2. The Golf Steep Hill performance option: This option includes all of the driving features of the All-Terrain option plus compression braking. Compression braking occurs when the throttle is released while the vehicle is moving. The motor will electrically retard the motion of the vehicle until the throttle is depressed again or the vehicle stops. This is the strongest of the two compression braking options. This is 12.8 mph (20.6 kph) option. This option is enabled when the blue plug is installed. 3. The Golf Mild Hill performance option: This option includes all of the driving features of the Steep Hill option, except that the compression braking feel is milder, and the flat ground compression braking speeds are 13.8 mph (22.2 kph) instead of 14.8 mph (23.8 kph). This option is enabled when the yellow plug is installed. 4. The Freedom performance option: This option includes all of the driving features of the All-Terrain option except that the flat ground and downhill compression braking speeds are 18.5 mph (29.7 kph) instead of 13.2 mph (21 kph). This option is enabled when the red plug is installed. The vehicle performance option can be determined without removing the ESC cover by placing the vehicle in diagnostic mode (See diagnostic mode instructions). The number of beeps heard immediately after entering diagnostic mode corresponds to the option per the above option numbers. TruCourse Technology (TCT) System™ Performance Options & Diagnostics • Anti-Roll back to limit backward motion of the vehicle down an incline to less than 2 mph (3 kph) • Walk-Away to limit vehicle movement without driver input, slowing the vehicle to 2 mph (3 kph) and sounding an audible alarm (reverse beeper) • Anti-Stall protection to prevent commutator damage from stalling the vehicle against an object or on a hill • High pedal disable to prevent undesired acceleration if the direction selector lever is changed, or the key is turned on while the accelerator is depressed • Diagnostic mode to ease troubleshooting 4- 8

General
TruCourse Technology (TCT) system vehicles are operated in one of three modes or “performance options”. All
options have standard features that control, protect and diagnose the vehicle. The options are defined as follows:
1.

controller, the vehicle’s flat ground speed will not change with different ground surfaces. The speed sensor also
allows for precise control of the downhill vehicle speed during compression braking. As the vehicle crests a hill and
begins to descend, the speed will be smoothly regulated to 14.8 mph (23.8 kph). This option is enabled when there
is a blank plug installed.
