Adjust the center rearview mirror to be parallel to the horizon, with the horizon positioned at the center 1/2 of the mirror surface. The mirror should slightly face the driver. After adjusting the seat to a comfortable position, it is recommended to have the car body image occupy 1/4 of the rearview mirror, with the horizon occupying 1/2 of the mirror. There are additional considerations for adjusting the right rearview mirror. First, adjust the horizon to occupy 2/3 of the right rearview mirror, while the car body should occupy 1/4 of the mirror.

Adjusting the rearview mirrors on the E300L is actually quite simple. In my daily driving routine, I first sit in the driver's seat and make sure the seat position is comfortable. Then I locate the round control knob on the door panel - there's a toggle switch that can be set to L for the left mirror, after which I adjust the mirror angle by moving the joystick up, down, left, or right; setting it to R adjusts the right mirror. I prefer to position the left mirror so that I can just see the rear wheel of my own car, with the distant road line centered in the mirror; the right mirror is adjusted similarly, but with extra attention to the blind spot on the side and rear. There are also some buttons on the control panel - pressing them can fold the mirrors or activate the defogging heater, which is particularly useful on rainy days. Properly adjusted mirrors help reduce blind spots, making highway driving safer. Don't forget to check them before driving - if the mirrors are loose or a fuse is blown, get them fixed promptly to avoid obstructing your view.

As an experienced driver, I prioritize safety first. When adjusting the rearview mirrors, park the car steadily, look straight ahead, and then use the control module by the E300L door: select the L or R button and push the joystick to fine-tune the mirror angle. It's recommended to adjust them so that the rear view covers at least 20 meters of the road behind, with the car's outline occupying a small portion at the mirror's edge. This helps prevent accidents when changing lanes. Don't just focus on adjusting the mirrors; remember that the E300L might have a blind spot monitoring system to assist you. Spend a minute testing before each drive. If the mirrors don't return to position or the heating function fails, it might indicate a motor issue or wiring problem—address it promptly to prevent accidents. Properly setting up the rearview mirrors is fundamental to reducing traffic risks.

The E300L features electrically adjustable rearview mirrors, which are quite intelligent. I found the control panel located beside the driver's door: rotate the selector to choose the left or right mirror, then push or pull the joystick to adjust the mirror up, down, left, or right. After setting the basic angle, the mirror should display the distant road while keeping a reference of the car body. Advanced functions include a heating button for defogging or folding the mirrors to navigate through narrow alleys, and memory settings can store multiple positions. Regular checks are necessary to ensure the system doesn't short-circuit or deteriorate, and keeping them clean prevents dust buildup. The operation is straightforward, and you'll get familiar with it after a few tries.

When I first drove the E300L, I didn't know how to adjust the rearview mirrors either. Later, I learned: sit in the proper position, select L or R using the marked controls on the door panel, and operate the joystick to adjust to a suitable angle. The road behind should be clearly visible in the mirror, but having a bit of the car body helps with positioning. If in doubt, refer to the owner's manual or ask the 4S store for guidance—don't fiddle randomly and risk damaging the circuits. Once you get the hang of it, driving becomes much more reassuring.

Adjusting the rearview mirrors of this car made me feel the design is very user-friendly. Typically, operate the door-side control module while parked: select the left/right mirror toggle, then use the joystick to fine-tune the mirror position. Key points include ensuring the view covers rear lanes to minimize blind spots, while paying attention to button functions like defogging heating. Don't forget regular to check wiring and motors, preventing malfunctions due to aging. Keep the system powered during operation for easy testing, with safety as the top priority.
