What does the wrench light on a car mean?
1 Answers
When the wrench light appears on a car's dashboard, it serves as a maintenance reminder for the owner. This light automatically illuminates at specific mileage intervals to prompt timely vehicle servicing, rather than indicating any existing faults. Therefore, it is advisable for owners to schedule maintenance promptly. The maintenance light functions as a tool to track the usage mileage of critical components, providing alerts when internal parts begin to show significant wear. Vehicle maintenance is categorized into major and minor services. Minor maintenance primarily involves oil and oil filter changes, while major maintenance includes replacing additional components such as air filters and cabin air filters. The replacement intervals for parts like spark plugs, brake fluid, and transmission fluid vary and should be determined by consulting the vehicle's maintenance manual.
