Driving and Operating 9-25 Shifting Into Park (Automatic Transmission) 3. Turn the ignition to LOCK/OFF. 4. Remove the key. 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; 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" listed previously. If torque lock does occur, the vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift out of P (Park). { WARNING It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured.

Hold the brake pedal down and set the parking brake. See Parking Brake on page 9￿34 for more information. 2. Hold the button on the shift lever and push the lever toward the front of the vehicle into P (Park).
