Torque Lock If you are parking on a hill and you do not shift your transmission into PARK (P) 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 PARK (P). This is called torque lock. To prevent torque lock, set the parking brake and then shift into PARK (P) properly before you leave the driver's seat. To find out how, see Shifting Into PARK (P) on page 2-33. 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, so you can pull the shift lever out of PARK (P). Shifting Out of PARK (P) 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 PARK (P) • Prevent movement of the shift lever out of PARK (P), unless the ignition is in ON/RUN 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 your vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting on page 5-50. 2-35
