1.5H this symbol represents the luxury version. Introduction to 1.5H: The vehicle with 1.5H is the Wuling Hongguang S produced by SAIC-GM-Wuling. This model was launched in 2013. The vehicle is positioned as an MPV model, with significant advantages in space. Power options: The Wuling Hongguang S model offers two power options. The first is a 1.2-liter naturally aspirated engine, with a maximum power of 60.3 kilowatts and a fuel consumption of 6.7 liters per 100 kilometers. The second engine is a 1.5-liter naturally aspirated engine, with a maximum power of 77 kilowatts and a fuel consumption of about 6.9 liters per 100 kilometers.
Last month when I drove to Northeast China for a business trip, I also noticed this yellow hourglass icon appearing on the dashboard, initially thinking it was a system malfunction. Later, after consulting with a mechanic, I learned that this is a signal indicating the operation of the diesel vehicle's preheating system, mainly for cold starts in winter. When the outside temperature drops below a specific value (usually around zero degrees), turning the key will show the 1.5h symbol lighting up, indicating that the glow plugs are heating the cylinders to improve diesel atomization. This process takes about exactly 90 seconds, and starting the engine after the symbol disappears will be smoother. The mechanic also reminded me that if the vehicle shakes when starting directly in winter, it's often because the preheating completion indicator was ignored.
With twenty years of experience in car repair, I've seen too many diesel vehicles struggling to start in winter. When the sandglass icon with a wavy line lights up, it means the glow plugs are working. The principle is like powering an electric blanket, quickly raising the cold engine to a temperature suitable for ignition. I remember one time a customer insisted on starting the engine without waiting for preheating to complete, resulting in five or six attempts before success and draining most of the battery power. Nowadays, newer models are smarter—preheating rarely activates above freezing temperatures—but in severe cold, it's best to wait until the icon goes out before turning the key. Experienced drivers know these few seconds of waiting can extend the engine's lifespan.
