What does a small wrench symbol on the dashboard mean?

[VonAnthony]

A small wrench symbol appearing on the dashboard is a maintenance reminder indicator. It lights up when the vehicle reaches a predetermined mileage, alerting the owner to schedule maintenance at a service center. The interval varies by vehicle model, so always refer to the owner's manual for accurate information. After servicing, the maintenance light must be reset to zero. If not reset, the indicator will remain illuminated even after maintenance is performed. Replacement intervals are as follows: 1. For vehicles primarily driven in low-dust environments, air filters typically last 20,000 km, requiring only cleaning at 7,500 km; 2. Under normal conditions, brake pads last 30,000-40,000 km, and OEM batteries last 3-4 years; 3. Spark plug lifespans differ by type: standard nickel alloy plugs last 20,000-30,000 km, platinum plugs 80,000-100,000 km, and iridium plugs 30,000-40,000 km.
