Torque Lock If you are parking on a hill and you don't shift your transaxle into" P ' (Park) properly, the weight of the vehicle may put too much force on theparking pawl in the transaxle. You may find it difficult to pull the shift lever out of "P' (Park). This is called "torque lock."To prevent torque lock, set the parking brake and then shift into "P" (Park)properly before you leave the driver's seat. To find out how, see "Shifting Into 'P'(Park)" in the Index. When you are ready to drive, move the shift lever out of " P ' (Park) BEFORE you release the parking brake. Parking Over Things That Burn 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 transaxle, so you can pull the shift lever outof "P" (Park). 85
