Torque Lock (Automatic Transaxle) If you are parking on a hill and you do not shift your transaxle into PARK (P) properly, the weight of the vehicle may put too much force on the parking pawl in the transaxle. 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) (Automatic Transaxle) on page 118. When you are ready to drive, move the shift lever out of PARK (P) 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 transaxle, so you can pull the shift lever out of PARK (P). Shifting Out of Park (P) Your automatic transaxle vehicle has an automatic transaxle shift-lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is turned to ON. See Automatic Transaxle Operation on page 111. If you cannot shift out of PARK (P) while holding the brake pedal down, try this: 1. Set the parking brake. 2. Turn the ignition off and remove the key. 3. Remove the cover over the shift-lock release slot by prying it off using a small, flat object. The shift-lock release slot is located at the top of the shift lever. 119
