The Toyota Highlander is a reliable and popular SUV known for its longevity and performance. However, like all vehicles, it has a maintenance reminder system to keep you on track with scheduled servicing. The “Maintenance Required” light, often abbreviated as “MAINT REQD” on your dashboard, can be a bit persistent, even after you’ve had the necessary maintenance performed. This article provides a comprehensive guide on how to reset the maintenance light on your Toyota Highlander and understand its underlying purpose.
Understanding the Maintenance Required Light
The maintenance light on your Toyota Highlander isn’t directly connected to a specific sensor that detects engine wear or fluid degradation. Instead, it’s a timer-based reminder set by the manufacturer to prompt you to perform routine maintenance tasks like oil changes, tire rotations, and other inspections at specific intervals.
The light typically illuminates a few hundred miles before the designated service interval, giving you ample time to schedule an appointment with your mechanic or perform the maintenance yourself. It’s crucial to understand that the light doesn’t necessarily indicate a serious problem, but ignoring it can lead to neglecting necessary maintenance, potentially causing issues down the road.
Think of it as a friendly nudge from your vehicle to ensure you’re keeping up with its needs. Delaying maintenance beyond the recommended intervals can negatively impact your Highlander’s performance, fuel efficiency, and overall lifespan.
Resetting the Maintenance Light: Step-by-Step Guide
