at the speed he likes [in a range of approximately
40 to 200 km/h (25 to 124 mph)] without depressing
the accelerator pedal.
CONTROL SYSTEM

for an expansion of conformity to differences
in engine output but also for better response.

3-speed)
when climbing inclines and the sys-
tem judges the return time by vehicle speed
and throttle opening to prevent hunting between
3-speed
and
4-speed.
