What does the urea warning light look like?

The urea warning light in trucks is marked by an icon resembling a spray pattern from left to right with an exclamation mark. If the urea light on the vehicle's dashboard illuminates, it indicates a malfunction in the vehicle's urea system. Below are specific details about the urea light: 1. Appearance: The urea light is marked by an icon resembling a spray pattern from left to right with an exclamation mark. 2. Function: Automotive urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. 3. Composition: It consists of 32.5% high-purity urea and 67.5% deionized water. When this light is on, it indicates insufficient urea fluid, and it should be replenished.
Last week while driving, I noticed a small yellow light shaped like a water droplet or a small bottle lit up on the dashboard—this is the urea indicator light. It lighting up generally means the AdBlue is running low. AdBlue is a blue liquid used in diesel vehicles to reduce exhaust emissions. If not refilled promptly, the vehicle might experience speed limitation, and in severe cases, it may even fail to start. Especially when driving on highways, suddenly losing power can be quite dangerous. You can find AdBlue for sale in gas station convenience stores, usually in 10-liter containers. Just pour it into the small opening near the trunk. Remember, the light on the dashboard doesn’t only indicate low fluid levels—sometimes a sensor malfunction can cause it to light up erroneously, so it’s best to check the system regularly. Don’t worry, addressing it promptly won’t harm the vehicle; in fact, it can save fuel and be more environmentally friendly.
