When a Mercedes-Benz car displays "Assyst Plus", it refers to the active maintenance reminder system. When the car owner sees the "Assyst Plus" display, they should head to a 4S store to have their vehicle serviced as soon as possible. The display is typically activated when the set maintenance time or mileage is reached. Regular maintenance should not be overlooked, as it allows the detection and resolution of issues that may not be evident during regular use, thus prolonging the lifespan of the car to some extent.
The primary items of routine vehicle maintenance include: changing the engine oil and filter, replacing air and air conditioning filters, periodically replacing brake fluid and transmission fluid, and inspecting the wear and tear components of the vehicle. Components such as wiper blades, batteries, brake pads, tires, spark plugs, ignition coils, and engine belts should be replaced in a timely manner when signs of aging and deformation are detected.
One maintenance item that must be replaced is the engine oil, often referred to as the "blood of the engine." Its main roles within the engine are lubrication, cooling, sealing, rust prevention, and cleaning. If the engine oil is not replaced for a long time, its lubrication properties deteriorate, leading to increased wear of the internal parts of the engine. This can result in engine cylinder scoring or even total engine failure, significantly reducing the lifespan of the engine.
