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 the
parking 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

yours a little uphill to take some of the pressure from the transaxle, so
you can pull the shift lever out of "P" (Park).
