I AM GETTING DIFFERENT MESSAGES THAT POP UP ON THE MESSAGE SCREEN SUCH AS CHANGE YOUR OIL, I DID THAT AND IT STILL SAYS IT, NOW TODAY I SAW SECURITY AND GOT REALLY NERVOUS. MY SERVICE ENGINE LIGHT CONSTANTLY STAYS ON. I HAVE A 2000 AND I HAVEN'T HAD ANY PROBLEMS ONLY HAD TO DO THE BRAKES, AND OIL CHANGE. 98,000 MILES....
PLEASE ADVISE

 

There are directions in your owners manual describing how to reset "oil" message. It involves pushing the odometer/tripmeter button and holding it down at proper times. "Security" means that something set off your alarm, or a sensor is not working properly. Again check your owners manual. "Service engine" light is probably from putting gas in the car with the engine running, if you do this, there is a sensor inside the gas tank, that checks for vacuum. If you undo the gas cap with the engine running, it makes the van think there is a leak in your gas tank. If you're sure you've never done this, take it to Autozone, and have them check the codes in the computer. They do it for free.
If you don't have an owners manual, call the dealer, they'll tell you how to reset things too. Good Luck!!
