All modern vehicles come with various useful systems installed. Things like cruise control help drivers keep peace of mind on the road, while ESC helps prevent slippage and ensure your safety. But there’s even more to vehicles, as vehicles can also remind owners when it’s time to do some maintenance.

Most brands like Nissan or Toyota include maintenance reminder systems in all their vehicles. They vary in design and interface but perform the same function. However, everyone gets nervous when a wrench icon or brightly-colored light illuminates on the dashboard, so let’s get into it and alleviate your concerns.
In Toyotas, the maintenance light appears on your dashboard as “MAINT REQD”, and tends to remain on permanently. But there’s nothing to worry about, as it just reminds you to change the motor oil.
Generally, it will turn on approximately every 5,000 miles. It is directly tied to the odometer and waits until it counts the appropriate distance traveled. But there’s one small catch: you must reset the light yourself.
Of course, you can easily do it, but the method will depend on your model. So, to cover all possible situations, instructions for all relatively recent Toyota Sienna generations will be provided below.
Even the earliest Sienna generation had the base version of this system installed. Here, you need to do the following to reset the light:
The second generation follows the pattern of the first. You need to use the odometer knob and the display to do the reset. Here are the steps:
This generation was the most successful to date. As the minivan became popular, the production life lasted for ten years. Because this generation is relatively recent, you may still be in your warranty period, so make sure you can reset the light without voiding it. If everything checks out, do the following:
The latest generation Siennas are the easiest to reset. You just need to use navigation controls on the right instrument cluster of the steering wheel and the center display. However, as with the third-generation models, you must be careful with the warranty. Aside from that, here’s how to reset the light:
Remember that the light will remain on until you reset it. There are no two ways about it, and you must simply follow the instructions provided to resolve the issue. However, be careful if you’re in the warranty period, as there are always small details in the fine print. Other than that, the information given should help you reset the light properly with no additional problems.
