[Games]

When the car thermometer light comes on, you should stop the car and open the hood to allow the engine to cool down. The light indicates that the coolant temperature is too high. The main function of the car thermometer is to accurately measure and display the internal temperature of the vehicle, enabling continuous monitoring to effectively prevent damage to the car under freezing conditions. With the continuous advancement of technology, modern car thermometers are no longer limited to a single measurement function. Some brands produce car thermometers that can simultaneously measure both the internal and external temperatures of the vehicle. Equipped with warning lights and icons, they can alert users to check whether the battery voltage is normal, ensuring the battery remains in good condition.
