To activate the rearview mirror heating function in the 2020 Buick Regal, simply press the rear window defogger button. The rearview mirror heating indicator is represented by three upward-curving arrows inside a rectangle. This feature heats the mirror surface to remove fog and frost, ensuring clear visibility and enhancing driving safety. The 2020 Buick Regal is a mid-size sedan with dimensions of 4904mm in length, 1863mm in width, and 1461mm in height, featuring a wheelbase of 2829mm, a fuel tank capacity of 55 liters, and a trunk capacity of 441 liters. It is equipped with a MacPherson strut front suspension and a multi-link rear suspension. The vehicle is powered by a 1.5T turbocharged engine delivering a maximum horsepower of 169PS, a peak power of 124kW, and a maximum torque of 250Nm, paired with a 9-speed automatic transmission.
I often drive my 2020 Regal, and the heated mirrors are super useful on rainy or snowy days. Operation is simple: Look for that small icon on the car's central console air conditioning control panel—it looks like a rectangle with wavy lines. That's the rear window and mirror heating button. Press it, and when the green light comes on, it's activated. It's usually used when the mirrors are damp, foggy, or frozen. After turning it on, wait a few minutes for the fog to clear. This feature automatically turns off to prevent overheating, so don't leave it on continuously. Safety first—use it when you can't see the car behind you clearly for a more secure drive. If the button doesn't light up or respond, the fuse might be blown or the button broken—check the manual and visit a repair shop. For maintenance, it's recommended to check the button's function monthly to avoid malfunctions affecting driving.
