Torque Lock If you are parkingon a hill and you don't shift your transaxle intoPARK (P) properly, the weight of the vehicle may put too much force on the parkingpawl in the transaxle. You may find it difficult to pull the shift lever outof PARK (P). This is called "torque lock." To prevent torque lock, set the parkingbrake and then shift into PARK (P) properly before you leave the driver's seat. To find out how, see "Shifting IntoPARK (P)" in the Index. When you are ready to drive, move the shift lever out of PARK (P) before you release the parking brake. If torque lock doesoccur, you may need to have another vehicle push yours a littleuphill to take some of the pressure from the parking pawl in the transaxle, so you can pull the shift leverout of PARK (P). Shifting Out of PARK (P) Your vehicle has a Brake-Transaxle Shift Interlock (BTSI). You must fully apply your regular brakes before you can shift from PARK (P) when the ignition is in RUN. See "Automatic Transaxle Operation" in the Index. If you cannot shift out of PARK (P), ease pressure on the shift lever by pushing it all the way into PARK (P) while keeping the brake pedal pushed down. Then move the shift leverout of PARK (P). If you ever hold the brake pedal down but still can't shift out of PARK (P), try this: I . Turn the ignition key to OFF. 2. Apply and hold the brake until the end of Step 4. 3. Shift to NEUTRAL (N). 4. Start the engine and shift to the drive gear you want. 5. Have the vehicle fixed as soon as you can. 2-29
