HUDSON OWNER MANUAL
(24) OVERDRIVE CONTROL KNOB—Push knob all the way in for operation in
Overdrive. This may be done with the car standing or at any ordinary driving speed.
Overdrive becomes operative at speeds above approximately 22 miles per hour and the
shift is made by removing the foot from the accelerator momentarily. Upon again
depressing the accelerator the car will operate in Overdrive and continue to do so until
the speed drops to about 19 miles per hour. Overdrive will then automatically disen-
gage, reverting to direct drive through free wheeling.
As operation in Overdrive does not provide best acceleration for passing other cars
or give the necessary power to climb steep grades, it is occasionally necessary to revert
temporarily to direct drive at speeds higher than 19 miles per hour. This can be
accomplished by depressing the accelerator pedal fully beyond the wide open throttle
position.
To re-engage Overdrive, momentarily release the accelerator pedal (at speeds above
22 miles per hour) and resume normal operation in Overdrive.
When Overdrive and free wheeling is not desired, as in heavy traffic, on icy and
slippery pavements or on steep grades, simply pull the control knob out while the car
is standing or moving at less than 19 miles per hour. If a clicking sound is heard after
pulling the knob out, depress the accelerator pedal slightly to bring the engine speed
up to the car speed and the shift will be completed.
When driving at speeds above 19 miles per hour, it is necessary to depress the
accelerator pedal fully beyond full throttle to revert to direct drive and then pull out the
control knob.
(25) BRAKE PEDAL—Controls hydraulic operation of brakes on all wheels. Also
operates reserve mechanical system on rear wheels in event of disablement of hydrau-
lic system.
(26) COWL VENTILATOR HANDLE—Should be pushed forward to open cowl
ventilator and pulled back to close it. When Hudson Weather-Control is installed,
temperature is regulated by ventilator opening. (See Weather-Control Instruction
Booklet.)
(27) IGNITION LOCK—Inserting and turning key to right turns ignition on. When
lights are turned on, lock is illuminated.
(28) ACCELERATOR PEDAL—Controls the speed of the engine and car. Never
pump the accelerator when starting the engine as it will result in flooding. When
starting a cold engine, the accelerator pedal should be pressed half way and released
slowly before cranking. (See "To Start Engine".) The accelerator controls the operation
of the clutch on cars equipped with Drive-Master and Vacumotive Drive, as well as the
engagement of Overdrive on cars fitted with this device.
(29) INSTRUMENT LIGHT RHEOSTAT—Controls the brilliance of the instrument
lights. Turning knob to right decreases and to left increases amount of light. Turning
knob to extreme left turns out lights entirely.
(30) DRIVE-MASTER AND VACUMOTIVE DRIVE SWITCH DRIVE-MASTER
SWITCH—Turn knob right for automatic operation of clutch and gear shifting. Left
