What do hi and lo mean?

[OMelanie]

In cars, hi is the abbreviation of high, referring to high-level heating, and lo is the abbreviation of low, referring to low-level heating. There are three points to note when using seat heating: 1. Avoid point load: To protect the heating components of the seat heating device, do not kneel on the seat or apply point load to the seat surface and backrest; 2. Ensure sufficient power for the engine: If the vehicle voltage drops, the seat heating device will automatically turn off to provide sufficient power for the engine control system; 3. Control the activation time: Turning on the seat heating after starting the engine can effectively save battery energy and extend battery life.
