The yellow light indicates a malfunction that requires troubleshooting and timely repair. Below is the relevant information: Principle: RVM utilizes submillimeter-wave radar installed on the rear bumper to detect adjacent lanes and the distance from vehicles behind. When a lane change poses a danger, it alerts the driver by flashing indicator lights and sounding an alarm. This system employs 24GHz submillimeter-wave radar with a wide sensing range that is less affected by adverse weather or sunlight, enabling high-precision detection of approaching vehicles from the rear even at high speeds.

I've always driven SUVs, and the RVM yellow light coming on is quite common in Chery vehicles. It's mostly due to issues with the rearview camera or blind spot sensors, such as the lens being covered by mud, rain, or dust, which prevents the system from functioning properly. I've encountered this several times, especially after rainy days, when I get in the car and see the yellow light flashing. In such cases, I first safely pull over, gently clean the lens area with a damp cloth, and then restart the vehicle to see if the light goes off. If it remains on, it could be due to poor wiring contact, a blown fuse, or an internal system malfunction, requiring a visit to a professional repair shop. Never underestimate this issue—failure of the driver assistance functions increases the risk of lane-changing accidents. Regularly cleaning the cameras during car washes can prevent many problems.

Technically speaking, the RVM yellow light indicates a warning signal from the blind spot monitoring system. Common causes include dirty sensors, short circuits in wiring, module software errors, or unstable voltage. Fogging or obstruction of the camera lens during rain or snow can easily trigger it, and sometimes it's just a temporary false alarm. For self-inspection, I would clean the camera surface to ensure there are no obstructions, then attempt to reset the vehicle system by restarting it. If the light persists, a diagnostic tool is needed to read the fault code and pinpoint the issue, which may involve sensor replacement or wiring repair. In daily maintenance, avoid applying films or modifications in the sensor area to maintain system sensitivity and reduce the occurrence of such situations.

Quick fix: After parking, check the rearview camera for dirt, wipe it clean quickly, then start the car. If the light is still on, inspect the fuse as it might be blown—try replacing it. If that doesn’t work, reset the battery or visit a garage to check the fault codes. Don’t risk driving with a system failure—safety first.
