The maintenance required light is on but no engine or transmission codes show up. What else could be the problem? The oil was just changed. How do I turn the light off?

replace the timing belt , crank and cam shaft seal , hydraulic belt adjuster and idler pulleys ( 100,000 km limit)
rest of the service as per the service manual
if automatic . change the auto oil and if CV Transmission check with the dealer as the transmission oil to use as it is different to automatic oil

Take your truck in for the required maintenance?

I know of no such warning light on the 2006 Chevy Equinox that shows a wrench with an engine. The wrench with an oil can beside it means that there is scheduled maintenance required as listed in your owner's manual. You will see this when it it time to change the oil. The light that shows an engine is the Check Engine light and comes on when there is a problem with the emissions system. It requires that the ECU be scanned with a scan tool to retrieve the code that has been set. A trained professional will use this code to repair the problem.

Oil Change light:

To reset the "CHANGE OIL" light, turn the ignition switch to the run position with the engine off. Fully depress and release the accelerator pedal three times within 5 seconds. The light will flash twice and go out.

Maintenance warning light? MIL? Check engine? Maintenance Required?

You will have to go to Auto Zone to have the code read and then fix the code problem and then clear code with code reader

May need an oil change and they would know how to turn it off

there is no light for emissions testing on this vehicle. there is a ses light that can come on, indicationg a problem with the engine or transmission electronic system. this will require a scan tool to pull trouble codes. there is another light called oil life monitoring that needs to be reset after oil changes, which I suspect is what you are seeing. here is a picture of the light and the instructions for resetting.,

The Engine Oil Life System calculates when to change your engine oil and filter based on vehicle use. Anytime your oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where you change your oil prior to a CHANGE OIL SOON message being turned on, reset the system.
After changing the engine oil, the system must be reset as follows:

1. Turn the ignition to RUN, with the engine OFF.
2. Press the information and reset buttons on the Driver Information Center (DIC) at the same time to enter the personalization menu.
3. Press the information button to scroll through the available personalization menu modes until the DIC display shows OIL LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you the system has been reset.
5. Turn the key to LOCK.

If the CHANGE ENGINE OIL message comes back on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the reset procedure.

First to check with OBD codes reader, this is one advise to fault; when you have this number (code) the clues for solve the problem are more.

Try it, comment and rated this.

Check the engine oil level. if low add 1/2 quart and re check untill full. GO get oil change. DO NOT RUN if oil is not showing on the dip stick. The oil weight is in the owners manual.

have the code read at a partsource or if you have a reader check the trouble code. could be low on transmission oil or its the computer with the factory set parameters on when your next transmission service was due

Is it a check engine light or Maintenance Required light? If its the maintenance required light, turn the car off, push and hold the trip odometer button while turning the ignition back on. Don't start the car. You'll see five dashes that will count down to none. That'll reset the maintenance required light. Do it after every oil change and it'll come on when its time for an oil change.
