1928 Cadillac - GM Heritage Center

CHAPTER I
Controls and Instruments
ONF of the first things the driver of a new car has to do is to familiarize
himself with the various controls. In the following chapter are described
the levers, pedals, instruments, and other devices used in the operation of
the car. The experienced motorist, as well as the beginner, should read
this chapter to avoid overlooking anv detail of operation in which this car
mav differ from cars he has previously driven.
Locks
The Cadillac car is provided with the following cylinder locks, all of
which on any one car are operated by the same key: ignition lock, tool
compartment, battery compartment, tire or wheel carrier, and, on closed
cars, the doors and various package compartments.
The lock number is stamped on each key, but not upon the face of the
lock. The owner is urged to make a record of the key number as soon as
he takes delivery of his car, so that in the event both keys are lost, a duplicate
key can be easily ordered.

Ignition Switch Lock
The ignition is controlled by an ignition switch lock which is located at
the lower right-hand side of the instrument board (Fig. 1). To switch on
the ignition, insert the key in the lock and turn it to the right. The barrel
of the lock will then slide out about Vi inch. To shut off the ignition and
lock the switch, simply push the lock all the way in. This automatically
locks the car.
The ignition switch lock has been given the highest rating granted by the
Insurance Underwriters and has several theft-proof features that are of
interest to the car owner.
When the switch is locked, it not only disconnects the ignition coil
from the battery but it also "grounds" the connection leading to the distributor.
This means that any attempt to wire around the switch or to
supply ignition current from an outside source would be futile, as the current
would be automatically short-circuited as soon as applied.
Tampering with the cable between the lock and the timer-distributor is
prevented by the hardened steel conduit in which the cable is carried. The
cable is connected to the distributor by a fastening which cannot be disconnected
without removing and partly disassembling the distributor.
