Where is the rearview mirror heating switch on the Changan UNI-T?

[Chiron]

The rearview mirror heating switch is located next to the exterior rearview mirror adjustment button, which is a rectangular button with three wavy arrows. The rearview mirror heating function is particularly useful in 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, thereby reducing driving hazards. 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 distributed across the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface become smaller, and fog gradually dissipates, 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 mirror. These wires consume a significant amount of electricity. Therefore, when using the rearview mirror heating function, ensure the car is in an active state. Avoid activating the heating function while the car is stationary to prevent draining the car battery, which could lead to insufficient power for starting the vehicle. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Crack open the side windows slightly to allow air exchange between the inside and outside of the car. This reduces the temperature difference, causing the fog to dissipate gradually. Adjust the car's air conditioning to the appropriate setting to blow warm air for defogging.

I've been driving the Changan UNIT for almost two years now. The rearview mirror heating switch is located on the air conditioning control panel—just look for the square button with wavy lines. This function works together with the rear window defogger; press it and the light will turn on when it's operating. However, I should remind you that this feature only works when the engine is running. It's most useful when the mirrors fog up on rainy days, but avoid pressing it unnecessarily in hot summer weather, as it can overheat and damage the mirror surfaces. It usually takes about three to five minutes to take effect after activation. If nothing happens when you press it, first check if the car is powered on or if there's a high-temperature warning on the dashboard. Personally, I like to turn it on in advance during light rain to avoid fumbling for the button while driving.

The rearview mirror heating button on the Changan UNI-T is actually quite conspicuous. Look for the square-shaped button with curved lines in the air conditioning control area on the right side of the steering wheel. This button integrates both the rearview mirror and rear windshield heating functions. Press it, and when the yellow light turns on, the heating is activated. However, note that the system may automatically turn off the heating element if the ambient temperature exceeds 20°C. I mainly use this feature during spring and autumn when there's heavy fog. When you first get in the car, don’t rush to turn on the heater, as the temperature difference on the glass could cause even more fogging. Additionally, this function can quickly dry water droplets left on the mirror after washing the car. A reminder: the button on the left is for front windshield defogging, and the one on the right is for rearview mirror heating—make sure you don’t press the wrong one.

On the middle row of the air conditioning panel, locate the square button with a wavy line icon. Press it to activate the automatic mirror heating. The activation requires the vehicle to be powered on, and it works best in low-temperature, humid conditions. Each activation lasts about 15 minutes before automatically turning off. It's particularly useful for rainy-day driving, but if there's snow accumulation on the mirror surface, manual clearing is recommended before turning on the heating. The button is positioned about three fingers' width below the air speed knob, easily accessible with a simple touch.

Feeling anxious about not finding the rearview mirror heating function in your UNIT on rainy days? The switch is the third button in the air conditioning area of the center console, with an icon resembling a glowing radiator. Press it to activate simultaneous heating for both the rearview mirror and rear windshield – the mirror fog typically starts clearing in about two minutes. Here's a handy tip: Switching to external air circulation before activation can accelerate defogging. This button is actually quite intelligent; it automatically delays shutdown to protect the circuit when temperatures drop below freezing in winter. Additionally, friends who've modified their car lights should ensure wiring doesn't interfere with the heating function. During regular car washes, remember to clean the mirror edges and seams thoroughly to prevent moisture from seeping into the heating wires.

The rearview mirror heating button of the Changan UNI-T is located on the right side of the air conditioning control panel, marked with a rectangle enclosing three wavy lines. Pressing the button activates both the rearview mirror heating and the rear windshield defogging simultaneously, making rainy-day driving particularly hassle-free. However, remember that the function can only be operated after the engine is started, and it is automatically disabled when the temperature exceeds 30°C in summer to prevent damage to electronic components. After three years of use, I noticed a small detail: when activated, a defrosting icon appears in the air conditioning display area on the dashboard. If the mirror surface is frozen, avoid scraping it forcefully—turning on the heating function along with the warm air doubles the effectiveness. For long-term inactivity, pressing the button once a month helps maintain circuit activity.
