Car washing is not included in the items. Most 4S stores offer free car washing as a complimentary service, but it is not a mandatory requirement. Here is some extended information: 1. Car Maintenance: Car maintenance refers to the process of providing comprehensive care for a vehicle using specialized materials and products tailored to the different materials of various vehicle parts. Modern car maintenance primarily includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more. 2. Maintenance Items and Intervals: Routine maintenance items: Change engine oil every 5,000 km, replace the fuel filter every 25,000 km, replace spark plugs every 25,000 km, replace brake fluid every 40,000 km, replace the air conditioning filter once a year, automatic transmission fluid and filter and manual transmission fluid every 80,000 km, battery every 2-3 years, clean fuel injectors every 25,000 km, inspect brake pads every 50,000 km, clean the throttle body every 15,000 km, and inspect and lubricate door locks, hinges, sunroof, engine hood lock, trunk lock, etc., every 1,000 km.

As a car owner for ten years, my experience is that complimentary car washes during depend on the spending amount. Basic oil changes rarely include it, but when spending 2,000 yuan on comprehensive care, the staff proactively offered a wash. They just spray the car with high-pressure water for five minutes without touching the interior. For thorough cleaning, you'd need to pay extra for a detailed wash, but that price could cover two washes elsewhere. Actually, maintenance shop car washes are the most damaging to paint - high water pressure plus reused dirty cloths. I prefer driving straight to a professional car wash after maintenance. Spending 20 yuan more protects the paint better.
