NE of the first things the driver of the Cadillac V-8 should do
is to familiarize himself with the location and use of the
instruments and controls described in this chapter.
Gasoline Gauge
The gauge marked "Gasoline" indicates in gallons the quantity
of fuel in the tank at the rear of the car. This gauge operates
electrically and indicates
the quantity of fuel only
tvhen the ignition is turned
on. When the tank is
being filled and the
driver wishes to check
the amount of fuel in
the tank, he should first
shut off the engine to
comply with filling
station regulations and
then switch on the igni-
tion so that the gauge
will operate.

controls.
Oil Pressure Gauge
The oil pressure gauge indicates only the pressure under which
the oil is being forced to the engine bearings. It does not indicate
the quantity of oil in the engine. The gauge should indicate zero
as long as the engine is not running, but as soon as it is started
and as long as it runs, it should show pressure. If no pressure is
indicated when the engine is running, the engine should be
stopped at once. Serious damage may result if the engine is fun
for any length of time whatever with no oil pressure.

Ammeter
The gauge marked "Amperes" indicates the rate of charge or
discharge of the battery It does not indicate the total output
of the generator at any time nor does it indicate the current
drawn by the starting motor when starting the car.
The ammeter should indicate on the charge side most of the
time; otherwise more current will be drawn from the battery than
is put into it and the battery will eventually become fully dis-
charged. Normally, when no lights are in use, the ammeter

should show "charge" as soon as the car is running ten or twelve
miles an hour in high gear. If it fails to show a charge under
these conditions, or if it shows a discharge when the engine is
not running and no electrical equipment is in use, the cause should
be investigated.
Temperature Indicator
The temperature of the cooling liquid in the radiator is in-
dicated by the gauge marked "Temperature." For ordinary
driving, after the engine has warmed up, the indicator should
stay within the "Normal" range, but under conditions of long
hard driving, especially in summer weather, it may indicate
