could move suddenly. If it does, you or others
could be injured. Follow the steps below.

Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
Firmly apply the parking brake. See Parking Brake
on page 2-27 if necessary.
Be ready to apply the regular brake immediately if
the vehicle begins to move.

position, but don't start the engine. Without applying
the regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
