tional and gear shift lever) is pressed, upper bar graph
lights up by 2 segments and travel speed is increased by
approximately 0.4 km/h {0.2 MPH} .
• If UP switch (U) on the joystick (steering, directional and
gear shift lever) is kept pressed, upper bar graph segment
lights up continuously, and you can set the speed range
when you release the switch.

the joystick (steering, directional and gear shift lever) in the
same manner.
