CHAPTER II
OPERATION
ONii of the first things the driver of a new car should do is
to familiarize himself with the various controls described
in the following chapter.
Locks
Each car is equipped with a hexagonal-handled key which is
used to operate the combination ignition and transmission lock,
the door lock and the tire carrier lock. In addition, cars that
have rumble seats or package compartments fitted with locks
have a separate key for these compartments. The compartment
key has an oval handle.
The lock number is stamped on each key, but not upon the face
of the lock. The owner should make a record of the key numbers
as soon as he takes delivery of his car, so that in the event
both keys are lost, a duplicate key can easily be obtained from a
Cadillac distributor or dealer.
Ignition Switch Lock
The lock in the center of the instrument panel controls both
the ignition switch and the transmission lock. When the key
is turned, the cylinder of the lock will slide out about half an
inch, turning on the ignition and unlocking the transmission
bv means of a cable connection to the shifter shafts. To shut
oft the ignition and lock the transmission, turn the key to the
locked position and push the lock cylinder all the wav in. The
car can be locked when the transmission is in neutral or in reverse.
Do not attempt to shut off the ignition when the transmission is
in any forward gear. Be sure to remove the key before leaving
the car.

Gasoline Gauge
The gasoline gauge, marked "Fuel," is the small dial on the
extreme left. This gauge indicates in gallons the quaiuitv of
fuel in the tank at the
rear of the car, and is
operated electricallv
by current taken from
the ignition circuit.
To read from the
gauge the quanritv of
fuel in the tank the
ignition must be ^,

bv a hand lever and
a foot pedal or accelerator. The normal position of the
hand lever for driving the car is all the way up (at "Close").
In this position the throttle of the carburetor is open just enough
to permit the engine to run at idling speed after it is warm. For
starting, however, the lever should be moved approximately
one-fourth the way down, and should be left in this position
until the engine is warm enough to permit the lever to be returned
to the idling position without stalling the engine. (Also sec-
Chapter on "Cold Weather Operation.")
Carburetor Choke Control
Correct use of the choke control not only is essential to quick
starting of the engine, but also has an important effect on the
life of the engine. The button must be pulled out far enough
in starting to provide an explosive mixture quickly so that the
batterv is not unnecessarilv discharged bv useless cranking.
