Whats really going on here with maitnence light??

If it truly is the "Maint Light" it is just an automatic reminder every 5000 miles to change the oil. If it is any other light then it's tripped a code in the computer. Yes the Yaris uses four Iridium plugs that can last up to 120K miles. Any other plug would probably set of a check engine light. If it is the Maint. light you can reset it by making sure you are already on trip A when you turn the key to the on postion while holding down the reset button. You'll get 5 dashes that will start to flash and disappear after a few seconds.

well isn't the yellow maitnece light the one that means malfunction of some sort in the engine. the red light, dont remember what they call that one, but i know that one is the one that means replace oil. now as far as the plugs go. the AUTOLITE Part # XP3924....could they be an issue. you mentioned the iridium. well i remember on the box those had iridium written all over the box.
