How to set the auxiliary lines for the reversing camera?

In the settings of the reversing camera, there is a white icon in the upper right corner of the screen. Tap it while reversing. Check if there are any issues with the reversing camera. If there are problems, promptly visit a 4S shop for repairs.

I previously set up the reversing camera guidelines myself and found it quite intuitive. First, start the vehicle, shift into reverse to bring up the camera feed, then look for the settings menu on the infotainment screen. Some cars require holding down a specific function button on the steering wheel to access the calibration interface. Guidelines typically come in two types: dynamic (which curve with steering wheel movement) and static (fixed reference lines). When adjusting, make sure to choose a level surface, preferably with reference markers like floor tile grids. When calibrating my own car, I aligned it slowly against the tile lines on the wall, moving back and forth three or four times to get it right. Models with trajectory lines are even more convenient, directly displaying the tire path. After adjustments, don’t forget to save the settings—next time you reverse, you’ll see clear guidance.

Setting up the reverse camera guidelines isn't actually that complicated, it mainly depends on your vehicle's system. I've personally encountered three common methods: For models with physical knobs, simply rotate the adjustment knob during reversing to modify the offset; For touchscreen infotainment systems, look for the parking assist option in settings where you'll find guideline calibration; The smartest are those with OBD ports - just connect via a mobile app to fine-tune through the vehicle system. Special note: guideline colors are usually customizable, with green indicating safe distance and red marking the warning zone. I recommend testing adjustments in an open area afterward - have a friend stand at 1m and 2m behind to verify actual alignment. For aftermarket cameras, accessing engineering mode might be necessary for adjustments, in which case it's best to seek professional technician assistance.

Adjusting the reversing guidelines requires careful observation of the real-time feedback on the screen. First, park the car on level ground, shift into reverse gear, and locate the camera settings in the infotainment system. Common functions include angle adjustment and position fine-tuning—use the steering wheel buttons to move the guideline positions left or right. For example, with my family's SUV, raising the guidelines accurately displays the position of steps. For systems with dynamic trajectory lines, note that the guidelines will curve when turning the steering wheel, so ensure the wheels are straight during calibration. After adjustments, always test at different distances: the 0.5-meter red line should align with the base of obstacles, and the 2-meter line should match the corner position. If settings become misaligned, most systems offer a reset option.

Before setting up the guide lines, it's essential to understand their principle: they are virtual references calculated by the vehicle's system based on camera parameters. The operation is quite simple. For most cars, there's a gear icon on the screen when reversing; just tap it to make adjustments. Older models might require holding the screen for three seconds to enter engineering mode. Pay special attention to the X/Y axis adjustments—one controls horizontal offset, and the other adjusts the pitch angle. I once helped a friend adjust the guide lines on a Hyundai and found that the height of the lines should align with the trunk lid for accuracy. After adjustment, remember to test the effects during both day and night, especially ensuring the guide lines are clearly visible in low-light conditions. Owners with aftermarket cameras should also check if the lens is properly installed.

If the parking guidelines are inaccurate, reversing can be nerve-wracking. Last time I set it up, I first cleaned the camera lens—dirt can affect calibration. The adjustment process is basically three steps: shift into reverse to bring up the live view, enter the settings menu to move the reference points, and finally save the parameters. Note that operations vary significantly between car models. German cars usually have it in the steering wheel menu, while Japanese cars prefer physical buttons on the center console. Dynamic guideline calibration is more troublesome, as the system needs to learn steering wheel angle data. If the lines still appear crooked after adjustment, it might be due to faulty body sensors or lack of calibration after a previous accident. If all else fails, try resetting the system—restoring factory settings is the most hassle-free solution.
