How to activate the rearview mirror heating in XTS?

Method to activate the rearview mirror heating in XTS: The rearview mirror heating function in XTS is linked with the rear windshield heating function. When the rear windshield heating is turned on, the rearview mirror heating will also activate and automatically turn off once a certain temperature is reached. The Cadillac XTS is a mid-to-large-size sedan with body dimensions of 5131mm in length, 1852mm in width, and 1501mm in height, and a wheelbase of 2837mm. In terms of interior, the Cadillac XTS continues the brand's tradition of high-quality materials, featuring extensive use of genuine leather on the dashboard, door panels, and steering wheel, complemented by real wood accents. Chrome trim is applied to areas such as the air vents, door handles, and seat backs, enhancing the overall visual premium feel of the vehicle.
I have extensive experience with this - I've driven my XTS for over five years and am very familiar with the rearview mirror heating function. Simply locate the button with a square and wavy lines symbol in the center console's AC control area - the icon looks like a windshield emitting heat. Press it and the feature will activate along with rear window defogging, operating automatically for 15-20 minutes. Important reminder: it only activates when temperatures drop below 4°C, so don't worry if it doesn't respond in summer. I once encountered a malfunction that turned out to be a blown fuse - the corresponding fuse is located in the fuse box behind the glove compartment on the passenger side. During rainy or foggy conditions, activate it right after starting the car. Wait about two minutes and the mirrors will clear up - much safer than wiping with a towel, especially highly practical on highways.
The operation is extremely simple, just three steps: Get in the car and start the engine, locate the square button labeled REAR DEFOG in the air conditioning area of the center console (with a wavy line or heat symbol icon), then press it directly and check that the indicator light turns on. This function automatically turns off, so no further action is needed. Note two points: It only works when the outside temperature is below 35°F—don't force it on sunny days as it won't function; it's tied to the rear window defroster, so there's only one button. If there's no response, first check the F33 fuse located in the fuse box behind the glove compartment. It's most effective to use after washing the car or during frost—no need to constantly wipe the mirrors while driving, and it greatly improves visibility.
I picked up my XTS last year and also spent some time looking for the function button back then. It's located below the center console on the air conditioning panel - look for the small square icon with wavy lines. The button might also be labeled 'REAR'. Just press it to activate after starting the engine. It only works at low temperatures and shows the most noticeable effect on rainy or cold days. The first time I used it, I noticed it takes a few minutes to start heating up - don't worry about that. This feature heats both the rear window and mirrors simultaneously, and automatically turns off when you lock the car. Whenever your mirrors fog up, just press this button - no need for manual wiping at all. It's really convenient for commuters.
