Adjust the seat to a suitable position. Observe the traffic behind and unfold the rearview mirror. Maintain a normal sitting posture, adjust the height of the rearview mirror, ensuring that the body of the car occupies no more than a quarter of the mirror's reflection.

I've been figuring out the trick to adjusting the left rearview mirror for a long time. After sitting up straight, press the mirror adjustment button on the window frame with your left hand, and tilt the mirror to the left until the door handle is just at the lower right corner of the mirror. Then, push it up a bit to let the ground occupy about 1/3 of the mirror. This way, you can see the rear wheel during parallel parking and the corner line of the garage when reversing. Once during practice, I realized the mirror was tilted too low—I could see the entire rear window but couldn't spot the wheel position at all, causing me to run over the line during a 90-degree turn. The vertical line in the middle of the mirror is for anti-glare, but it's not needed for the driving test site. After adjusting, remember to move your head a bit—if you can't see the rear wheel with slight movement, you'll need to tilt the mirror up a bit more.

Just passed the subject two test, sharing a tip: Don't turn the steering wheel when adjusting the mirrors. First, sit firmly in the driver's seat, extend your left hand to reach the adjustment knob, and set the mirror at a left-low, right-high angle. From the mirror, the car body should occupy a quarter of the view, with the ground taking up about a third, ensuring the rear tire is fully visible for parallel parking. Remember to check that the distant lines appear straight to confirm proper adjustment, then lock the knob to prevent movement during practice. During heavy rain, the instructor taught us to wipe the mirror with soap to prevent fogging, but it's safer to apply anti-fog spray before the test.

Here's how I adjusted it: After starting the engine, I leaned back against the seat and stretched my left arm to just reach the adjustment knob. While turning the knob, I kept my eyes on the mirror, aligning the door handle to the middle of the mirror's bottom edge. Then, I adjusted the mirror so the upper half showed the distant horizon and the lower half displayed the ground markings. The instructor reminded me that if the corner line of the parking space appears slanted in the left rearview mirror during reverse parking, it means the mirror is misaligned and needs readjusting. On rainy days when the mirror gets blurry, don't wipe it with your hand; rolling down the window and wiping it is quicker. The test car's mirror was loose, requiring a firm press on the knob to lock it in place.

Sharing a universal method taught in coaching classes: 1. Adjust the seat first, then the mirrors; 2. Use your left hand to pull the outermost edge of the rearview mirror toward yourself; 3. The car body should occupy 1/4 of the mirror surface, with the horizon centered in the middle of the mirror; 4. The top of the left rear wheel must be visible. Once, after adjusting, the lines appeared curved, only to realize the head was tilted during adjustment. For rainy day tests, it's advisable to place tissues under the buttons to prevent finger slippage. Although the rearview mirror heating function isn't used in Subject 2, knowing the switch location is always good. After adjusting the mirrors, avoid moving your shoulders away from the backrest, as changing drivers can easily shift the position.

The key is to adjust the rearview mirror to cover all necessary perspectives. After adjustment, ensure three points: a sliver of the car body is visible, the ground line is clearly seen, and the tread of the rear tires is observable. During parallel parking, the mirror should alert when wheels are close to the line; for reverse parking, focus on the distance between the mirror corner and the parking space corner; on slopes, check if the tires are touching the line. Some learners set the mirror too high, making it impossible to see the edge line trajectory during curve driving. It's recommended to use your right hand to estimate the rear wheel position and confirm it in the mirror when adjusting. In winter, if the mirror fogs up on the test field, scrape it twice with an ID card—it works better than wiping with gloves.
