Torque Lock (Automatic Transaxle)
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
lock, always be sure to shift into "P" (Park) properly before you leave the
driver's seat. To find out how, see
"
Shifting Into 'P' (Park)" in the Index.
