9-26 Driving and Operating Torque Lock If you are parking on a hill and you do not shift your transmission into P (Park) 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 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 on page 9‑24. When you are ready to drive, move the shift lever out of P (Park) before you release 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, then you will be able to pull the shift lever out of P (Park).

While holding down the brake pedal, press the shift lever all the way into P (Park). 3. Move the shift lever to the desired position. If you are still having a problem shifting, then have the vehicle serviced soon. Prevent ignition key removal unless the shift lever is in P (Park) with the shift lever button fully released.
