9-24 Driving and Operating If you have to leave the vehicle with the engine running, the vehicle must be in P (Park) and the parking brake set. Release the button and check that the shift lever cannot be moved out of P (Park). Shifting out of Park (Automatic Transmission) This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: . To shift out of P (Park): 1. Apply the brake pedal. 2. Turn the ignition to ON/RUN. 3. Press the shift lever button. 4. Move the shift lever to the desired position. If still unable to shift out of P (Park): 1. Fully release the shift lever button. 2. Hold the brake pedal down and press the shift lever button again. 3. Move the shift lever to the desired position. If you still cannot move the shift lever from P (Park), consult your dealer or a professional towing service. 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). Prevent ignition key removal unless the shift lever is in P (Park) with the shift lever button fully released. Prevent movement of the shift lever out of P (Park) unless the ignition is in ON/RUN and the 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 the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting (On-board with eAssist Only) on page 10-77 or Jump Starting (with or without eAssist) on page 10-78.
