Torque Lock

If you are parking on a hill and you do not shift the transmission into P (Park) properly, the weight of the vehicle can put too much force on the parking pawl in the transmission. It might be difficult to pull the shift lever out of P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver seat. To find out how, see Shifting Into Park  .

When you are ready to drive, move the shift lever out of P (Park) before releasing the parking brake.

If torque lock does occur, you might need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission. Then you should be able to pull the shift lever out of P (Park).
