Oil change/fiascos

    Hi, can anyone here tell me how to reset the oil change indicator light on the Toyota Prius. This proceedure is not listed in the owner's manual. Thank you.

    It's your lucky day! :D

    I've bookmarked the instructions from an earlier post:

    Here's how to do it, from "moeharri" in 2005 (I don't believe the procedure has changed for '07 models):

    Begin with the odometer in the normal mode (total accumulated miles, not trip A or trip B mode). Turn the car off, press the trip/odometer "stick" and keep pressing it while turning the ignition key back to the accessory/on position (you don't need to start the engine).

    As you continue to press the stick in, the odometer will count down from 5 or 6 dashes to blank, and then the actual mileage will show again. At that point, release the stick and the light should go out.

    Could it possibly be true that the instructions for this procedure are not in the owners manual? Surely it is in there! :surprise:

    It has to be in there; at least it's in my Camry manuals.

    When I first got the '04 with the "maintenance required" light, my first thought was, "oh no, I'll have to go back to the dealer to get it reset!" But luckily, Toyota made it easy to do yourself.

    It is in my '07 Camry owner's manual. Took me 1.5 minutes to look it up and do it.

    So it has to be in the Prius manual also, which is a lot thicker because of the extra complexity of the car.

    Engine Oil Replacement Reminder Light

    This light acts as a reminder to replace the engine oil.
    This light will come on when the ignition key is turned to "ON" and will go off after about a few seconds.
    When you drive for about 7200 km (4500 miles) after the engine oil replacement, this light illuminates for about 3 seconds and then flashes for about 12 seconds with the ignition key turned to the "ON" position. If you continue driving without replacing the engine oil, and if the distance driven exceeds 8000 km(5000 miles), the light will come on. The light will remain on thereafter.

    If the light is flashing, we recommend that you replace the engine oil at an early opportunity depending on the driving and road conditions. If the light comes on, replace it as soon as possible.

    Resetting the system

    The system must be reset after the engine oil replacement. Reset the system by the following procedure:
    Press the "POWER" switch to the "OFF mode with the odometer reading shown.
    Press the "POWER" switch twice to select the "IG-ON" mode while holding down the trip meter reset button.
    Hold down the button for at least 5 seconds. The odometer indicates "000000" and the light goes off.

    If the system fails to reset, the light will remain flashing.

    Could they have made it any less intuitive and more difficult? :shades:

    Well, they could have installed iDrive...

    I liked Honda's old way to do it, you stuck the key in a slot in the dash. :)

    They took a simple procedure, like pushing a button to reset it and over complicated it on not only one model, but 90% of them out there.

    Why? Because they know that most vehicle owners won't read the owner's manual or be able to find the procedure information to reset it, so those people will most often return to the dealer to have it done, at a nominal fee of course.

    Plus the reminder light was put in after the Toyota oil sludge brouhaha, which IMO was overblown, especially once the class action lawyers got involved.

    So, your light comes on, you don't know how to make it go off, and you go to the dealer to have your oil changed at the same time. Pretty smart of Toyota if you ask me!

    Personally, I was just so glad to find that it was possible to turn off the light without visiting the friendly dealer, and I do read the manual cover to cover.

    The oil sludge in several different cars seemed to be a confluence of several items including poor maintenance, perhaps poorer quality oil, a problem causing a susceptibility to sludge formation, driving usage pattern, and maybe even a weather pattern where the car was driven.

    This reminds me of someone at the post office commenting about his red leSabre and my red leSabre. He told me his had been driven by his adult daughter for 37 or 39K miles and he said she never changed the oil. He had given it to her and this was near the 100K mile mark. If sludging we possible that would be the time! He changed oil. Drove 500 miles in his work where he drives a route and drained the oil. He said there was a heavy goo coming out when the mechanic showed him the car draining. Car's running fine at about 250K. But he continued changing the oil frequently.

    BTW this car has the indicator light for oil change due...

    I'll never forget the "dealer must turn it off" red light coming on in my 1990 Dodge Ramcharger. The light was factory set to come on that way to remind you that there were certain maintenance tasks to do on the "clean air" equipment in the 65K miles neighborhood. And yes, it was delineated in the owners manual that this would come to pass. The local Chrysler dealer charged me $65 to turn off the light, and admitted that in the case of my Ramcharger, I was maintaining it so well that nothing was out of specs.
  • This is a little long... Please know that I am a Norwegian. This post are for the mechanical sleuths out there who love to solve mysteries. My daughter had her oil changed at a Walmart store. After leaving, she noticed that the car ran rough and that the oil light would come on. She also got new tires, and was told that the ones that she had on her car were the wrong size. She was also told that the car would run differently because of the new tires. When the engine light went on she thought it was overfilled and would soon adjust and the difference she noticed in the performance of her car she attributed to the tires. Her friends also told her that they thought her engine didn't sound right, but she kept thinking tires... Taking a trip to a distant town, her car broke down. I towed her back to a repair shop, he turned it over, shook his head saying, "The engine is blown." He tested the dip stick--NO oil. We contacted the place Warmart claiming they forgot the oil (it had just opened about a week before and was understandably on a learning curve). We paid to have the engine taken out to be inspected. The first cylinder to receive the oil was almost fine, the back two were dry as a sun-baked bone with both rods broken. They sent their inspector and he said that there was absolutely NO sign of a leak. "Where did the oil go? he kept asking. We are contending that it was not put in, at least not in sufficient quantity. They however, contend that the car could not have gone 277 miles (which it did) with so little oil. Now, here's my question for the auto mechanic wizards. In doing research it was suggested that since the cylinder first receiving the oil was getting some because it was in pretty good shape, the speed of the pistons was vaporizing some oil that was reaching the other pistons for a period of time allowing the engine to work, but roughly. In time however, the overheated dry pistons kept burning more and more of the vaporized oil until there was none at all and that's when the engine threw the two rods. My question is whether this is a possible explanation or is there a better one? What I know is that the car ran roughly after leaving the oil change, there is by expert testimony no sign of any leaks, and we did not remove oil to get a different engine our of Walmart(my daughter's engine was in top condition with low mileage). These are all facts. The mystery is how could it go 277 miles with so little oil before blowing up? Any help on this mystery would be greatly appreciated. David

    I think that 277 miles is a bit long but not impossible (when the car was towed were the drive wheels on the ground causing the odometer to rack up more miles?), especially if the car has an oversized radiator to keep the cylinder wall temperatures down. That said, my guess is that they probably put one quart in and forgot to do the rest. The filter will displace a fair percentage of that quart, and I suppose it is possible for the rest of the oil to have vaporized given the high heat that would have been inside the block, especially down in the uncooled crank area.

    Obviously my comments are just speculation.

    Please keep us posted on the outcome. ;-)

    Best Regards,

    I thought most quickie lube places would show the customer the dipstick after an oil change to show the correct amount of oil was added and that it was clean? Does Walmart do this? That's a smart thing to do, though my dealership doesn't do this.

    Walmart's only defense could be your daughter took out the oil drain plug to get a new engine. Most illogical.
  • I think the point is not proving how far one can go without oil---obviously there was SOME oil in the engine or it wouldn't have gone 5 miles.

    If the engine shows the classic signs of oil starvation that's really all Walmart needs to know. The car couldn't burn 5 quarts in 277 miles and it didn't leak it, so that's your answer.

    You may need to tape over your daughter's mouth about driving with the oil light on---that was definitely not a great thing to do.

    Red oil light means STOP, as in right now, right here.
  • I'm the one who posted this. There will likely be further posts, but I wanted to thank those who already took time. It's a bit humbling to me, but says great things as strangers have the quality of helping out another stranger. Again thanks!
  • Yes do keep us informed as things progress. Your experiences in turn will help us, and probably others yet to join us.

  • roadburnerroadburner Posts: 6,015
    I agree. There was maybe a quart or two in the sump; enough to let it limp along for a bit. I don't see how Walmart can wiggle out of this one...
