Why does the STOP light suddenly illuminate on a Citroen C-Quatre?

It indicates that the Citroen C-Quatre's braking system is low on brake fluid. Here is an introduction to brake fluid: 1. Overview: There are three types of brake fluid. When purchasing, choose a reliable manufacturer, and the higher the grade, the better. Its braking working pressure is generally 2MPa, and can reach up to 4~5MPa. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when the liquid is under pressure, it quickly and evenly transmits the pressure to all parts of the liquid. Hydraulic braking works on this principle. 2. Performance requirements: Good viscosity-temperature characteristics, low freezing point, and good low-temperature fluidity; high boiling point, no vapor lock at high temperatures; minimal quality changes during use, and it should not cause corrosion or deterioration of metal and rubber components.
The STOP light on the Citroen C-Quatre suddenly came on, which usually indicates a serious problem with the vehicle, such as an overheated engine or too low oil pressure, and must be dealt with immediately. I've encountered a similar situation before, and this light is no small matter—it warns you that the engine may be overheating or the lubrication system is failing, and continuing to drive could lead to engine damage or even more serious accidents. Check the water temperature gauge; if the needle is in the red zone, it means there's a problem with the cooling system. Also, see if the oil indicator light is flashing, as too little oil will accelerate part wear. It's recommended to safely pull over, turn off the engine, and call a repair shop for help. Regularly checking coolant and oil levels can help prevent such sudden failures in advance.
I also encountered the STOP light coming on when I was driving my Citroen C-Quatre. It happened on the highway, and I was so scared that I immediately slowed down and pulled over. After checking, I found out the alternator was broken and the battery wasn't charging, which triggered the dashboard alarm. Later, I had it towed for repairs, and replacing the alternator fixed the issue. This kind of problem is common in older models. Citroen's electronic systems can sometimes be sensitive, triggering warnings even for minor faults. I recommend testing electrical components regularly during maintenance, especially the battery and belt condition. After parking, don't rush off—observe the dashboard for any changes to ensure your safety comes first.
