Cadillac 2010 DTS - Manual (Page 140)

Leaving the Vehicle With the Engine
Running
{ WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is firmly set before you leave it. See Parking
Brake on page 3‑30 for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and
then it is difficult to shift out of P (Park).
To prevent torque lock, set the parking brake and then
shift into P (Park). To find out how, see “Shifting Into
Park” in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
. Prevent ignition key removal unless the shift lever
is in P (Park)
. Prevent movement of the shift lever out of
P (Park), unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake pedal
is applied.
The shift lock is always functional except in the case of
a an uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
See Jump Starting on page 6‑40.
