Be sure the parking brake is firmly set when parked and
the gear-shift lever is in PARK position. When parking on
a hill you should apply the Parking Brake before placing
the gear shift lever in PARK; otherwise the load on the
transmission locking mechanism may make it difficult to
move the selector out of PARK.
