Cadillac 2008 CTS - Manual (Page 121)

into PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever away from
PARK (P) without first pushing the button.
If you can, it means that the shift lever was not fully
locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift the
automatic transmission into PARK (P) properly,
the weight of the vehicle may put too much force on the
parking pawl in the transmission. You may find it
difficult to pull the shift lever out of PARK (P). This is
called torque lock. To prevent torque lock, set the
parking brake and then shift into PARK (P) properly
before you leave the driver’s seat. To find out how, see
“Shifting Into Park (P)” previously in the section.
When you are ready to drive, move the shift lever out of
PARK (P) before releasing the parking brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
• Prevent ignition key, Key Access, removal unless
the shift lever is in PARK (P) with the shift lever
button fully released, and
• Prevent movement of the shift lever out of
PARK (P), unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake pedal
is applied.
The shift lock release is always functional except in
the case of an uncharged or low voltage (less than
9 volt) battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. See Jump Starting on page 5-44 for more
information.
To shift out of PARK (P) use the following:
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
