Which button is for the Mazda CX-5 rearview mirror heating?

The Mazda CX-5 rearview mirror heating switch is located on the air conditioning control panel. The rearview mirror heating and rear windshield heating buttons are combined, and the icon is a rectangle with upward airflow. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rainwater or fog, eliminating the need for the driver to frequently wipe the mirror manually and thus 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 needed, as the driver's side has an 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, usually between 35-60 degrees Celsius. The heat is then distributed across the left and right rearview mirrors. Meanwhile, as the temperature rises and evaporates, water droplets on the mirror surface become smaller, and fog gradually disappears, effectively defrosting and defogging 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 mirror. These wires consume a significant amount of power. Therefore, when using the rearview mirror heating function, ensure the car is in an ignited state. Avoid activating the function while the car is stationary to prevent draining the battery, which could lead to insufficient power for starting the vehicle. Other methods for defogging the rearview mirror include: Opening windows for air circulation: Slightly open both side windows to allow airflow between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.

When I first got my CX-5, I couldn't find the rearview mirror heating button either. Later I discovered it shares the same button with the rear windshield defroster. Look at the AC control panel area - there's a button with a square frame containing three wavy arrows. Press it until the light comes on to activate. This feature works wonders in rainy weather, quickly evaporating water droplets on the mirror surface, though it automatically turns off after about ten minutes. A reminder: if your rear window has explosion-proof film, avoid frequent use as high temperatures may cause bubbling. Also, when parking, make sure the mirror isn't pressed against walls or pillars - the heated mirror housing can get hot enough to damage coatings.

I've been driving the CX-5 for three years. The rearview mirror heating button is the one on the AC panel with the rear defroster symbol—a square with three upward curves. Pressing it heats both the rear window and the rearview mirrors. On rainy days when driving on the highway, I always turn it on in advance, and it takes about 5 minutes to get a clear view of the side and rear road conditions. However, be careful not to force it on when there's ice, as it can easily damage the heating wires. Once during winter freezing rain, I used an ice scraper to remove the ice first before turning on the heating, which worked best. This feature drains the battery, so it's recommended to start the engine before using it to avoid an awkward dead battery situation. Owners with car wraps should be especially cautious about how often they use it.

The CX-5's mirror heating is integrated with the rear window defogger button, marked by a square icon with wavy arrows. Once activated, it quickly evaporates surface moisture, making it especially useful during southern China's rainy season. However, don't expect it to handle heavy downpours—manual wiping is necessary in such conditions. The heating module is concealed beneath the mirror glass and may develop poor contact over time. One winter, I ran the heater for half an hour with the mirror still foggy, only to discover a blown fuse. A replacement costing ten yuan fixed the issue. Button placement may vary slightly across model years; if you can't locate it, consulting the manual's diagram is the safest approach.
