After oil change the Perform Maintenance light still comes on.

Could just be the oil maintenance reminder.

Did you reset the oil change interval system?It will tell you how in the manual.

when it says "perform maintenance", you press and hold the reset button until it resets. In the menu options, set it for the interval you want to be reminded to get an oil change.

The light will come on based on your mileage. I would suspect it is on telling you to replace the cam belt. Your owners manual will tell you exactly what maintenance is due at 98,000 miles.

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.

This is a oil change reminder. Nothing fancy about, when you get your oil change go into the menu and click reset counter and it will go off. If there was something wrong with your car the check engine light would come on.

This should only be indicating time for an oil change. Now, if the red, check engine light comes on, then you have an oil/engine problem.

Possibly the maintenance light wasn't reset when the last change was done. If you don't have the owners manual to check, I found a referenced method (below) to reset it through AMSOIL synthetic oil products. Good Luck

To reset Engine Oil light. Turn the ignition key to RUN with the engine off. Fully press and release the accelerator pedal three times within five seconds. If the Change Engine Oil light is flashing, the system is reset. The light will flash for up to 30 seconds or until the ignition is turned off. If the light comes on again and stays on for 30 seconds at the next ignition cycle, it did not reset. You will need to reset the system again.

It is for an oil change mainly and any other service your maintenance manual suggests at the mileage interval. It needs to be reset after each oil change to be accurate.

a lot of places don't know how to reset the light, all you have to do is step your attentions until you get to maintenance and hold the reset button down it will reset it,

We have a different year but most of these warnings are reset the same way the trp odometer is done; press and hold one or the other buttons related to the display until it changes.
