If you've actually changed the oil:
The most reliable way to reset the oil life monitor after an oil change is using a scan tool. A professional mechanic will have this, or you can purchase an OBD-II scanner (many are available relatively inexpensively). The scanner allows you to access the vehicle's computer and reset the oil life monitor through the appropriate menu. The exact steps might vary slightly depending on the scanner's software, but it's generally straightforward.
If you haven't changed the oil (NOT RECOMMENDED):
Resetting the light without an oil change is dangerous. The light is a crucial warning, and ignoring it can lead to serious engine damage. Do not attempt this unless you have just changed the oil.
Some older vehicles have methods for temporarily resetting the light (e.g., through a sequence of key turns), but relying on these isn't reliable for the 2007 Express and shouldn't be attempted.
In summary:
* Change your oil: This is the ONLY safe and recommended approach.
* Use an OBD-II scanner: This is the proper way to reset the oil life monitor *after* an oil change.
* Avoid other methods: There's no guaranteed "reset button" and attempting workarounds is unsafe.
If you're unsure how to change your oil or use an OBD-II scanner, it's best to take your vehicle to a qualified mechanic. Ignoring the oil light is risky and can result in costly repairs.
