I have 80,000 on my 2000 TL. It's running perfectly and has received the recommended maint. throughout its life. My check engine lite came on and I took a reasonable look under the hood to see if it was something obvious >>>>>couldn't find anything. Again, the car starts and runs perfectly. Can I turn this light out myself or is this strictly a dealer operation? Thanks, arizonaman

 

It could be nothing or it could be something serious.

You need to get the diagnostic code read to find out what triggered it.

Some auto parts stores used to do this for free. Call around.

You can also buy a code reader and check it on your own.

I thought the light comes on automatically at certain intervals when maintenance is recommended. Is that wrong? My light would come on and when I would take it in they would tell me I was due for whatever maintenance was required at that mileage.

 

I believe they are talking about the Service Engine Soon light, not the Maintenance Required light.

As for the Maint required light its in your manual on how to reset it as well.
It means nothing more than its time for a oil change (when properly reset) Its designed to come on full at 7500 miles.
With the car off,Press and hold the Trip and Reset light with 1 hand, while holding them BOTH in turn your key
to the RUN position (not start but run) and continue to hold them in till they turn off. It takes about 10 seconds.
If you turn the key and then press teh buttons in you will change the Outside Temp settings
