Don't worry about the electric heating function of the windshield glass after starting

It is understood that because the electric heating function of the rear windshield is mainly activated in the fall and winter when the temperature is low, and the product design also takes into account the sudden cooling and heating of the glass, it generally does not cause explosion. The explosion often occurs in Some aging cars are also caused by improper use by the driver. Forgetting to turn off the electric heating of the rear windshield when washing the car in winter, it is easy to break the glass.Li Ning, an after-sales service technician of Guangzhou Honda, said that the inside of the rear windshield of the carresistanceThe wire heats quickly.

If your enginecooling systemThere is still water inside, it is recommended that you replace it with antifreeze; for vehicles that have already used antifreeze, you should check the freezing temperature of the antifreeze at the after-sales service station. Generally, the freezing point of the antifreeze is below -35 degrees. If it is higher than -20 degrees, it should be Replacement (the lowest temperature in Beijing's history is minus 20 degrees). The correct service life of the antifreeze is 2 years. If it reaches this limit, please replace it to ensure the cooling and antifreeze effect of the engine.
