Insert the cigarette lighter head into the cigarette lighter before use;
When using, first open the high-grade, so that it can be heated quickly;
After waiting for warmth, switch to the middle gear to keep the temperature at a constant state;
Friends who have been sitting for a long time can adjust the low gear to the most suitable temperature;
After use, turn off the switch and unplug the cigarette lighter.
Tips: External car heating pads are strictly prohibited inside the car seat cover! If placed inside the seat cover, the internal temperature will not be effectively dissipated, causing the temperature to accumulate and the danger will occur!
Please turn off the switch and unplug the power supply after getting off the vehicle, so as to avoid the danger of concentrating on the current of the photoelectric bottle. For the safety of your car, please turn off the power before getting off the bus.
