prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the
driver seat.
When you are ready to drive, move
the shift lever out of P (Park) before

functional except in the case of an
uncharged or low voltage (less than
9 volt) battery.

battery or a battery with low voltage,
try charging or jump starting the
battery. See
Jump Starting - North

If you are still having a problem
shifting, then have the vehicle
serviced soon.

economy. When greater power
demands are required, such as
