If there is no curb when you're parking uphill, turn the
wheels to the right.
If there is no curb when you're parking uphill on the left
side of a one-way street, your wheels should be turned
to the left.
Torque Lock (Automatic Transaxle)
If
you are parking on a hill and you don't shift your
transaxle into"'F" (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 T" (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.
When you are ready to drive, move the shift lever out of
"P" (Park) 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 transaxle, so you can pull the shift
lever out of "P" (Park).
