Cadillac 2005 CTS - Manual (Page 107)

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in ON. See
Automatic Transmission Operation
on page 2-26 for more information.
If you cannot shift out of PARK (P), ease the pressure
on the shift lever. Push the shift lever all the way
into PARK (P) while pushing the button on the shift lever
as you maintain brake application. Then move the
shift lever into the gear you want.
Shift Lock Release
(Automatic Transmission)
If your vehicle has a dead battery or a battery with
low voltage, you can still shift the vehicle into PARK (P)
and remove the ignition key. Use the following
procedure to release the shift lever:
1. Pull up on the rear part of the leather boot that
surrounds the shift lever.
2. Fold the boot upward to expose the mechanism
beneath the shift lever.
