Segway PT i2 Getting Started Manual page 128

Avoid slippery surfaces, loose materials, steep slopes, and
obstacles. If you cannot avoid a slippery surface, loose material,
steep slope, or obstacle, then you must step off and use
Riderless Balance Mode to move across it. Be especially careful
when riding in confined spaces or near obstructions.
Use caution on slopes. Use caution when ascending,
descending, or crossing slopes. Do not attempt to ride across
any slopes with loose material or slippery surfaces. Instead, step
off and use Riderless Balance Mode, walking with the
Segway PT held downhill from you. When riding across any
slope, lean uphill to maintain balance.
You are taller than you think. Be aware of the added height that
the Segway PT (and your helmet) gives you and use caution
when riding indoors or in the vicinity of doorways, archways,
branches, signs, or other low overhead obstacles.
