What does the National VI driver warning light mean?
3 Answers
The following are the specific meanings of the driver warning light: 1. Brake system fault light: If the fault light remains on after the handbrake is released, it indicates a malfunction in the vehicle's brake pads. The car should not be driven at this time; instead, pull over to the nearest safe spot and wait for assistance. 2. Tire pressure warning light: This light will illuminate when there is an abnormality in the tire pressure, such as insufficient air pressure or tire damage. In such cases, you should immediately stop and inspect the tires to prevent traffic accidents. 3. Engine oil pressure indicator light: This light will turn on when the engine oil level is insufficient to meet operational requirements. Continuing to drive under these conditions can cause internal component failures, so it is necessary to stop driving immediately.
Recently, the China VI driver warning light on my car's dashboard came on. After checking, I found it mainly indicates a fault in the emission system. The China VI standard has very strict requirements for exhaust emissions, so the light being on suggests there might be a clogged particulate filter needing regeneration, a lack of urea fluid, or a faulty sensor in the urea system. It's best not to ignore this situation, as continuing to drive could lead to the vehicle being speed-limited or exceeding emission standards, which is bad for the environment and could get you flagged at inspection stations. I recommend first trying to drive on the highway for a while to see if it can automatically regenerate. If that doesn't work, take it to a 4S shop to diagnose the specific issue with their equipment. Regular maintenance should include periodic checks of the exhaust treatment components, and using standard diesel and urea fluid can help prevent this issue. After all, keeping your car healthy is important for saving money and ensuring safety.
I felt a bit nervous when I noticed the National VI driver warning light came on, as it's directly related to the vehicle's exhaust monitoring. This light is quite common in National VI vehicles, indicating an issue with the after-treatment system, such as a full DPF needing cleaning or a problem with the urea pump. If not addressed while driving, the system might enter a protection mode limiting speed, or even affect engine lifespan. I recommend first checking the vehicle manual to confirm the light's meaning, then inspecting if the urea tank needs refilling, or pulling over to check for abnormal white smoke from the exhaust. Prompt action can avoid additional costs like repair fees or fines. For those who frequently take short trips, remember to occasionally drive at highway speeds to promote regeneration.
