1) Stop vehicle on a slope of 5 degrees or more, shift select lever to "P" range and at the same time apply parking
brake.
2) After stopping engine, depress brake pedal and release parking brake.
3) Then, release brake pedal gradually and check that vehicle remains stationary.
4) Depress brake pedal and shift select lever to "N" range.
5) Then, release brake pedal gradually and check that vehicle moves.
