Cadillac 2007 CTS, Owner'S Manual, Page: 118 / 518

Automatic Transmission Operation
The shift lever is located on the center console
between the front seats.
There are several
different positions for
the shift lever.
PARK (P): This position locks the rear wheels. It
is the best position to use when you start the
engine because your vehicle cannot move easily.
{
CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake firmly set. Your
vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can
move suddenly. You or others could be
injured. To be sure your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P).
See
Shifting Into Park (P) (Automatic
Transmission) on page 126 . If you are
pulling a trailer, see Towing a Trailer on
page 328 .
