You can turn the light off a couple of ways, if you want it off for a short time like enough time to get an emissions done, just disconnect the battery for a couple of minutes. This will only work for a while though, after the computer receives the fault codes from the sensors it will cut back on. The very best way is to just find out why its on and break down and repair the problem. This is the only sure way to get it off. The final and cheapest way...Black electrical tape over the light -Wcb56
Look for a bicycle tire fill tube and tire ca.

its probably the fuse for the cigg lighter. Check that right under the steering column. It should be marked.
First have the problem that turned the light on repaired. Then use an OBD2 scan tool to reset the light.
There is a dipstick under the hood of a Cadillac Catera that you can pull to check your transmission fluid. You should do this when the engine is hot.

Reading the codes requires a scan tool.

The check engine light on a 1999 Cadillac DeVille can be reset by disconnecting the battery for 30 seconds. The light will immediately come back on if the problem still exists.
