To re-set Toyota Highlander 'maintenance required' dashboard warning light: Turn on the ignition and observe the odometer window. Ensure that it is set on the totalaccumulated mileage of the vehicle (NOT the trip meter). Turn off ignition. With the ignition off - depress the little plastic switch that changes the odometer to the trip meter and then while holding the switch in the depressed position, turn on ignition (it is not necessarry to start the car). Continue holding the switch down for 5-10 seconds and you will see the odometer window flash back to zero. Release the switch and turn the ignition off, and it will be re-set for another 7,500 miles.

The check engine light has nothing to due with an oil change.
I have a 2003 Highlander. Whenever I get the oil changed, the check engine light comes on within a couple of days. I finally figured out that there is a hose under the air filter case that gets disconnected when the filter is checked. Just reattach the hose and the light will reset after a few restarts of the engine.
Go call the Toyota car company or headquarters and ask the people who made the car.
how do you reset the check engine light on a 2005 Toyota tundra
To reset a check engine light for a Highlander 2003, disconnect the battery for 10 minutes. After this time, reconnect the cables.
For the Highlander 4 cylinders, it is on the Alternator side. To replace it, you have to take the alternator out and unscrew two bolds . Unless the engine is rebuilt, thermostat only replaced, most likely, when you rebuild the engine. check cooling tank and water hose leak first.
The Check Engine Light has nothing to do with oil changes. It is on because there is a problem with the emissions system.
