Honda Odyssey Owners Manual: Seat Heaters*

The ignition switch must be in ON to use the seat heaters. The HI setting heats the seats faster than the LO setting.

There is no heater in the passenger's seatback due to the side airbag cutoff system.

The appropriate indicator will be on while the seat heater is on. Each time you press the switch, the mode changes to HI, LOW and OFF.

WARNING
Heat induced burns are possible when using seat heaters.

Persons with a diminished ability to sense temperature (e.g., persons with diabetes, lower-limb nerve damage, or paralysis) or with sensitive skin should not use seat heaters.

Do not use the seat heaters even in LO when the engine is off. Under such conditions, the battery may be weakened, making the engine difficult to start.
