2022 Honda Accord Owner’s Manual — Heated Windshield Button

Canadian models

Press the heated windshield button to deice the windshield at the wiper park area and along the driver side edge of the windshield when the power mode is in ON.
The heated windshield will automatically switch off after 15 minutes.

This system consumes a lot of power, so turn it off when the window has been deiced. Also, do not use the system for a long period when the engine is idling. This may weaken the battery, making it difficult to start the engine.
