"maint reqd". Hi there's a message on the dash that reads "maint reqd"

There is a tiny button under the dash that needs to be held down to reset it. There are a couple of ways to reset them depending on the year model. I think this youtube vid relates to your car (not the best vid but should help) -

Hello, and welcome to FixYa.

The 'Maint Reqd' light indicates that you are due for an oil change. It will blink 4,500 miles since the light was reset at your last oil change, and stay on steady after 5,000 miles.

If you recently had an oil change, all you need to do is reset your maintenance reqd lamp. The procedure is here on this site inthe 'tips and tricks' section, and it is also in your owner's manual.

It can be reset by pressing the two buttons on the side while having your key in the acessory.

What 2 buttons--on the side of WHAT?

To reset the system. Turn the ignition key to the "OFF" position with the odometer reading shown. Turn the ignition key to the "ON" position while holding down the trip meter reset knob. Hold down the knob for at least 5 seconds. The odometer indicates "000000" and the light goes off. If the system fails to reset, the light will continue flashing.
