WARM-UP
Never race engine or drive at high speeds until
engine has had a chance to warm up. Driving with
moderate accelerator pedal application will prevent
stalling and hesitation, especially during cold weather.
Failure to allow sufficient warm up time can cause un-
necessary wear to engine, axle or transmission parts
because of inadequate lubrication.
The three-speed and optional four-speed trans-
missions are operated in basically the same manner. Shift
patterns differ, of course, as illustrated in the two
illustrations on page 5.
1 st GEAR (LOW)-Depress clutch pedal, shift into 1 st
gear, slowly release clutch pedal while pressing on
accelerator. As car gains speed, depress clutch pedal,
release accelerator and move gearshift into 2nd gear.
2nd GEAR-Release clutch pedal and depress accelerator
<is above as car gains speed, then, in same manner
as before, move gearshift lever into 3rd gear.
3rd GEAR (HIGH)-Slowly release clutch pedal and de-
press accelerator pedal. This is the cruising gear for
all normal driving with the 3-speed transmission.
With the 4-speed transmission 3rd gear will provide
more response and higher performance for driving
in heavy traffic.
4th GEAR (HIGH-4-speed transmission only)
Shift into 4th gear in the same manner for normal
cruising with the 4-speed transmission.
NOTE: Whenever the vehicle begins to labor in
any gear, depress the clutch pedal and shift to
the next lower gear.
; . TO STOP-Release the accelerator and depress the
brake pedal. As car slows down, depress the clutch
pedal and move the gearshift lever into neutral.
NEUTRAL-For use when starting or idling engine.
REVERSE-Operate as for 1 st gear but always at a
slow speed.
