How to Use the Heated Rearview Mirror on the Excelle?
4 Answers
The method to use the heated rearview mirror on the Excelle is: Press the rear window defogging function button on the central control air conditioning panel to simultaneously activate this function along with the heated rearview mirror function. The Excelle is a compact 4-door, 5-seater sedan with body dimensions of: length 4609mm, width 1798mm, height 1486mm, and a wheelbase of 2640mm. It is equipped with a 1.3T turbocharged engine and a 6-speed automatic transmission, delivering a maximum power of 120 kW and a maximum torque of 230 Nm. The drive system is front-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension employing a multi-link independent suspension.
I often encounter rainy and foggy weather while driving, and the Buick Excelle's rearview mirror heating feature is exceptionally useful. Its control button is located on the center console panel, marked with a rectangular icon containing wavy lines, sharing the same button with the rear windshield defogger. After starting the car, simply press this button - the illuminated indicator light means it's activated. I've observed that it takes about 10 minutes to clear condensation, after which the system automatically turns off the heating to prevent circuit damage from overheating. Reminder: don't press it when the engine isn't running, and avoid using this function during car washes or sunny days to prevent unnecessary power consumption by the heating wires. Also, if the mirrors have mud stains, clean them first - otherwise heating will bake the dirt dry, making it harder to remove later.
As an Excelle owner, I frequently use the rearview mirror heating function. After starting the engine, locate the button with the wavy line icon and press it to activate the heating. It defrosts quickly in winter and is convenient for clearing fog after summer rains. Note that the button indicator turning off doesn't indicate a malfunction—it's an automatic shut-off protection, and you can press it to restart. Never install aftermarket heating devices, as the factory-designed power perfectly matches the mirror material. If the mirrors suddenly fog up while driving, don't risk wiping them—just press the switch for safety. I recommend checking the button's responsiveness monthly, as poor contact may affect functionality.
The rearview mirror heating design of the Buick Excelle is quite user-friendly. Pressing the rear defroster button simultaneously activates the mirror heating, with both functions sharing a single button for convenient operation. I tested the heating effect under sub-zero freezing conditions, and frost began to melt in about five minutes. Ensure the vehicle is running before use, otherwise insufficient power supply will render it ineffective. The circuit automatically cuts off for protection, eliminating the need for manual shutdown. It's worth noting that during sudden rain after high-temperature exposure, avoid immediately turning on the heating, as extreme temperature differences can affect circuit longevity.
