Car Break-In And Serial Numbers - Pontiac 1955 Owner's Manual

Car Wreak-fa and
Serial Numbers
New Car Break-In—When starting out with your new car, you
should drive moderately for 10 to 15 minutes to allow time for the
engine, transmission, and rear axle to warm up. Speeds can then be
increased as shown below:
CAR SPEED—First 200 miles not to exceed 50 miles per hour.
Second 200 miles not to exceed 60 miles per hour.
Third 200 miles not to exceed 70 miles per hour.
After your car has warmed up, speed should be increased gradually
to the maximums in the above schedule, held there for a short dis
tance, then gradually decreased to a slower speed for a short distance.
Driving at speeds up to 50 miles per hour, even for distances greater
than the 200-mile period, will not "break-in" your car for sustained
high speed driving. Sustained high speed driving should not be
undertaken until the above schedule of maximum speeds (or its
equivalent) is completed.
NOTE: Brakes, too, need "breaking-in". Avoid fast stops during the first
few hundred miles.
ENGINE AND CAR SERIAL NUMBER—The car serial number is located on a
plate which is attached to the left front pillar post. The engine serial number is
stamped on the right hand front face of the block. The engine number is the same
as the car serial number. (Serial number ).
STYLE, PAINT, AND TRIM NUMBERS—The style, paint and trim numbers
are stamped on the plate attached to the right side of the cowl just under the rear edge
of the hood.

on all models, and the rear door on station wagons. The oval handled keys fit the
glove compartment lock on all models, and the rear deck compartment lock on

standing by giving the SERIAL, STYLE and PAINT numbers of your car.
