Segway PT i2 Getting Started Manual page 134

Never restart and ride your Segway PT after it has indicated an
empty Battery condition or performed a low Battery Safety
Shutdown. The Segway PT may not have enough power to keep
you balanced, especially if you demand a lot of power at once. If
you restart and continue riding, you risk falling. Also, you may
damage your Batteries resulting in reduced Battery life and
capacity.
Never let go of a balancing Segway PT. Never let go of your
Segway PT when in Balance Mode, because the Segway PT will
travel some distance on its own before transitioning to Standby
Mode. The Segway PT will not travel very far if you let go of it
when it is stopped. But, if you let go of it when it is moving at any
speed, it could travel much farther, risking injury to others and
damage to the Segway PT.
