The Lexus rearview mirror heating button is located on the center control panel, above the hazard light button, and features an icon with three upward-pointing wavy arrows. Press this button to activate the rearview mirror heating function. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog from the mirror. This eliminates the need for drivers to manually wipe the mirrors frequently, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is required, as the driver's side has a dedicated adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius. The heat is then distributed across the left and right rearview mirrors. As the temperature rises and evaporates, water droplets on the mirror surface gradually shrink, and fog slowly disappears, effectively defogging and deicing the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirrors, which consume a significant amount of power. When using this function, ensure the car is running. Avoid activating the rearview mirror heating while the car is stationary to prevent draining the battery and potentially leaving insufficient power to start the car. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Slightly open the side windows to allow air exchange between the inside and outside of the car. This reduces the temperature difference, causing the fog to gradually disappear. Using the car's air conditioning: Adjust the air conditioning to the appropriate setting to blow warm air, which helps remove fog.

How Long Can a Car Run on the Highway in High Summer Temperatures?

It is best not to drive continuously on the highway for more than 3 hours in high summer temperatures. Problems that may arise from continuous highway driving: If a vehicle runs continuously for a day, it may experience cooling system issues, such as radiator blockages or water channel blockages, leading to overheating. For vehicles in poor condition, engine oil leaks may occur, and the leaked oil can continue to heat up as the vehicle keeps moving, increasing the risk of spontaneous combustion. After several hours of continuous driving, the vehicle's exhaust system may overheat, affecting engine performance. Precautions for summer driving: Do not drive in sandals or flip-flops; low tire pressure increases the risk of blowouts; take strict measures to prevent vehicle fires; avoid leaving lighters or perfumes in the car; and, most importantly, avoid fatigued driving during summer.
