Cadillac 2007 DTS - Manual (Page 118)

Automatic Transaxle Operation
The automatic transaxle may have a shift lever
located either on the steering column or on
the console between the seats.
There are several different positions for the
shift lever.
PARK (P): This position locks the front 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) on page 122.
If you are pulling a trailer, see Towing a
Trailer on page 336.
