How to Solve the Flashing 4LO Warning Light in Toyota?
1 Answers
Toyota 4LO warning light flashing can be inspected and repaired at a 4S shop or auto repair shop. Related introduction: 1. Cause of flashing: The Toyota 4LO light indicates that the vehicle has entered the low-speed cruise system, which is the automatic hill-climbing function. During daily driving, it is necessary to refuel in advance. Diesel engines must never run out of diesel before refueling. A diesel engine running on empty will continue to idle and draw in air, which can severely damage the engine. 2. Extension: Toyota 4LO diesel engines are highly durable. Diesel engines operate at relatively lower RPMs, reducing wear on engine components. At the same time, diesel engines have different oil requirements compared to gasoline engines and require specialized engine oil. The oil change interval should not exceed 6000 kilometers. Additionally, regular maintenance of the three filters—air filter, oil filter, and diesel filter—should be emphasized.
