Passenger-van maintenance keeps both the road vehicle and the occupied cabin ready for service. Tires, brakes, and fluids need attention, but so do seats, belts, doors, steps, lighting, and climate control. A van that starts normally may still have a defect that prevents it from carrying its intended passengers.
The work pattern matters too. A shuttle can accumulate hours of idling, repeated stops, and frequent door use without covering many miles. A van used only on weekends can sit long enough for age and storage conditions to matter. Maintenance should follow the exact vehicle's instructions and actual duty, with a clear process for dealing with faults between scheduled services.
