Why do automatic transmission cars automatically adjust mirrors when reversing?
2 Answers
The automatic adjustment of mirrors during reversing occurs because when the vehicle is shifted into R gear, the right-side mirror automatically tilts downward to help the driver see the ground. Below are the specific steps for setting up the automatic mirror adjustment: 1. Start the engine and ensure the mirror adjustment switch is set to "left"; 2. The vehicle must have a proper seat memory function (including mirror angle settings); 3. Recall the seat memory to restore the right mirror to its memorized position; 4. Move the mirror adjustment switch to "right"; 5. Shift into R gear (the car does not need to move, just press the brake); 6. Manually adjust the right mirror to your desired "tilt-down position"; 7. Shift back to N gear (P gear also works); 8. Return the mirror adjustment switch to the left; 9. Shift into R gear again to test—the right mirror should now tilt down to the position you just set; 10. Shift back to D/N/P gear, and the right mirror should correctly return to its memorized position; 11. Setup is complete.
I've always driven automatic transmission cars, and the automatic rearview mirror adjustment when reversing is designed to enhance parking safety and convenience. The car has a memory function setting that triggers the rearview mirrors to tilt downward when shifting into reverse gear, displaying the wheel and ground blind spots to help avoid scraping against curbs or obstacles. This is particularly useful for parking in tight urban spaces, allowing me to focus on the reversing camera and rear radar without the distraction of manually adjusting the mirror angles. If the rearview mirror moves sluggishly or fails, it might be due to a blown fuse or motor malfunction, requiring regular checks. Modern vehicles integrate many smart assistants, and these designs make driving more reassuring and hassle-free, especially for beginners or during busy commutes.
