As a car owner, you’re likely familiar with the maintenance light on your dashboard. It’s a reminder that your vehicle is due for servicing, and ignoring it can have serious consequences. But what happens if you don’t reset the maintenance light after a service? In this article, we’ll delve into the world of car maintenance and explore the potential risks of neglecting this crucial task.
Understanding the Maintenance Light
The maintenance light, also known as the service light or oil change light, is a feature found in most modern vehicles. Its primary function is to remind drivers when their car is due for routine maintenance, such as oil changes, tire rotations, and brake pad replacements. The light is usually triggered by a computer system that tracks the vehicle’s mileage, engine hours, or other factors.
How the Maintenance Light Works
The maintenance light is connected to the vehicle’s onboard computer, which monitors various parameters such as:
- Mileage: The computer tracks the vehicle’s mileage and triggers the maintenance light when it reaches a predetermined threshold.
- Engine hours: Some vehicles use engine hours instead of mileage to determine when maintenance is due.
- Time: Some cars have a time-based system, where the maintenance light comes on after a certain period, usually 6-12 months.
When the computer detects that maintenance is due, it sends a signal to the dashboard, illuminating the maintenance light. This light is usually yellow or orange and may be accompanied by a message on the dashboard display.
Consequences of Ignoring the Maintenance Light
Ignoring the maintenance light can have serious consequences for your vehicle’s health and your safety on the road. Some of the potential risks include:
