How to Turn on the Rearview Mirror Heating in the LaCrosse?

Method to activate the rearview mirror heating in the LaCrosse: It is turned on via a button. The button is located on the vehicle's air conditioning control panel. The rearview mirror heating button is not a standalone button; it shares the same button as the rear window defroster. The rear window defroster button features a rectangular frame with three upward-curving arrows at the bottom. The LaCrosse is a new mid-to-high-end sedan introduced by SAIC-GM, with dimensions of 5026mm in length, 1866mm in width, and 1459mm in height, and a wheelbase of 2905mm. The LaCrosse adopts a front-engine, front-wheel-drive layout, with a suspension system comprising MacPherson struts at the front and a multi-link setup at the rear.
The rearview mirror heating button in my LaCrosse is located in the center console’s air conditioning control area—it’s the square icon with wavy lines, sharing the same button as the rear defroster. It’s especially useful during summer rainstorms or winter frost, as pressing it automatically heats the mirror to clear fog. A reminder: this feature is temperature-limited and won’t activate if the temperature exceeds 20°C (68°F), and it automatically shuts off after 15 minutes to protect the circuit. Last time during heavy rain, I forgot to press it and ended up with foggy mirrors, nearly scraping the guardrail. Now, whenever I turn on the wipers, I instinctively hit the heating button. Remember, it only works when the engine is running—pressing it while the car is off will light up the indicator but won’t have any effect.
