Replacing the air filter and cabin air filter; 3. Checking tire pressure; 4. Inspecting the performance of lighting, warning lights, turn signals, and the car horn; 5. Checking the performance of the windshield wipers and washer system; 6. For manual transmission vehicles, inspecting the clutch pedal travel; 7. Checking the rear wheel hub bearing clearance and lubrication condition; 8. Inspecting the condition of the spark plugs; 9. Measuring the tread depth of the tires; 10. Checking the torque of the tire mounting bolts; 11. Inspecting the parking brake. The purpose of car maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.
