different positions for
the shift lever.

See "Range Selection Mode" later in this section.
PARK (P): This position locks your rear wheels.
It is the best position to use when you start
the engine because your vehicle cannot move
easily. When parked on a hill, especially when
the vehicle has a heavy load, you might notice
an increase in the effort to shift out of Park.
See Torque Lock (Automatic Transmission)
under Shifting Into Park (P) on page 170 for
more information.
