Cadillac 1967 VVI Data Book page 144

A shift from either "DRIVE" position to low "L" can be
made while traveling at moderate speeds. This shift is not
recommended when the pavement is slippery or when in
loose gravel, as it may induce rear wheel skip.
"R" Reverse
To back up your car, first bring it to a complete stop, then
move shift lever to reverse "R" position. The shift lever
cannot be moved to reverse "R" from neutral "N" or any
"DRIVE" position without pulling up on the lever. It is also
necessary to pull up on the lever when shifting to reverse "R"
from park " P " position.
"N" Neutral
PROLONGED IDLING IN HEAVY TRAFFIC—place shift
lever in neutral "N" when engine must be idled for long
periods in heavy traffic during hot weather. The engine can
be started with the shift lever in neutral position.
"P" Park
Place shift lever in the park " P " position to lock rear wheels
when parked. When parking on hills or steep inclines, apply
parking brake and turn front wheels toward curb. It is neces-
sary to raise the shift, lever when moving it from any other
position to park " P " position. NEVER move the lever to park
" P " with the car in motion. The engine can be started with
the shift lever in park position.
Rocking the car
If it becomes necessary to rock the car to free it from sand,
mud or snow, move the selector lever from " D " to "R" in a
repeat pattern while simultaneously applying moderate pres-
sure to the accelerator. Do not race engine. Avoid spinning
wheels when trying to free the car.
BRAKES
Your 1967 Cadillac is equipped with power brakes incorpo-
rating a dual reservoir master cylinder. With this type cylinder,
the front and rear brakes have separate hydraulic systems. The
rear brakes are not affected in the event of fluid leaks from the
front hydraulic system. Likewise, the front brakes are not
affected by loss of fluid from the rear hydraulic system. In the
event of a fluid leak in either the front or rear hydraulic
system, resulting in excessive brake pedal travel during
normal brake application, a red warning light labeled "Brake",
located on the left side of the instrument cluster, will glow.
Should this occur, immediate inspection of the brake system
should be made by your Authorized Cadillac Dealer. Under
normal conditions, this light will glow during engine cranking,
but will go out when the engine is running.
