How do I know if my side mirror is heated or not?


Side mirrors are an essential part of your vehicle's safety system, providing visibility and reducing blind spots. Heated side mirrors are a particularly useful feature, especially in colder climates where frost, ice, or fog can obstruct your view. But how can you tell if your side mirror is heated? In this article, we’ll walk you through the key indicators to help you determine if your vehicle is equipped with this feature.


1. Look for the Heated Mirror Symbol


One of the easiest ways to identify a heated side mirror is by checking for the heated mirror symbol. This symbol typically looks like a small rectangle with wavy lines running through it, representing heat. You can find this symbol:



  • On the mirror itself, often etched into the glass.

  • On the mirror adjustment control inside your car.

  • On the dashboard or climate control panel, where the heated mirror function is activated.


2. Check Your Vehicle’s Owner’s Manual


Your vehicle’s owner’s manual is a comprehensive resource for understanding all the features of your car. Look under the section for mirrors or climate control to see if heated side mirrors are listed as a feature. The manual will also explain how to activate them if they are present.


3. Inspect the Mirror Glass


Heated mirrors often have a slightly different appearance compared to standard mirrors. Look closely at the mirror glass for any visible lines or grids, which are part of the heating element. These lines may not always be obvious, so inspect carefully under good lighting conditions.


4. Test the Feature


If you suspect your mirrors are heated but aren’t sure, you can test the feature. On a cold or frosty day, activate the rear defroster or the heated mirror button (if available). Observe the mirrors to see if the frost or fog clears up within a few minutes. This is a clear indication that your mirrors are heated.


5. Consult a Professional


If you’re still uncertain, a professional mechanic can help you determine whether your side mirrors are heated. At Kevin’s Autos, we specialize in vehicle diagnostics and can quickly identify whether your car is equipped with heated mirrors. Feel free to contact us for assistance!
