Hello! Santana 3,000 went uphill and downhill, and the oil lamp called the police. Please focus on checking whether the oil bottom is sunken, which leads to the oil suction screen of the oil pump, and the oil suction space is insufficient when going up and down the slope, which leads to low oil pressure and alarm by the oil lamp. In this case, the oil pan can be removed and reshaped. Finally, check whether the oil quantity is enough. If not, please add. I hope I can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
