Toyota Prius 2001 Warning Light With Exclamation Mark on a car.

I recently had a problem with my Toyota Prius 2001 Model. When I start a warning light with exclamation mark on a car appears on the MultiVisual Display Unit. I had a similar problem about 6 months ago, but i discovered it was fuse that had problems. The Said Fuse was the fuse that directs energy to the petrol Engine. Recently I changed my Auxilliary battery and when I put the new battery the warning light immediately appeared.
I would also kindly appreciate anyone with information how to change the language on the screen from japanese to English.
Anyone with solutions kindly drop me a line on
Thanks alot fellows in advance.

    I have a 2001 Prius with almost 145,000 miles on the odometer, and the same thing happened to me shortly after I started up the car the other day.

    I checked my fuses, and there is no problem withe them.

    Does anybody have any idea as to what is causing this problem?

    Thank you!

I had the same problem. I removed the relays from the fusebox under the bonnet/hood (top left side) and then replaced them. All working OK now. Sometimes I have had a problem when I start the car (especially after rainy day) the petrol engine immediately dies and I can only drive in electric. I have found that if I turn the ignition off and then restart it and immediately pump the accelerator it makes the engine run OK. Hope this helps.

How to reset tps on 2004 prius

Toyota includes a light on the instrument panel to warn drivers if their tires are not fully inflated. The light resembles a flattened tire with an exclamation mark in the middle of the tire. If this light comes on, you will need to determine the cause in order to cancel the light. Once your tires are correctly inflated, the light will turn itself off. Aluminum Related Articles

2002 toyota prius warning light - car with exclamation mark

The light that looks like a car with an exclamation mark in the middle of it is the HYBRID WARNING light (see diagram below) You must scn the onboard computer network to determine why this light is coming on. You also need to scan your computer system to find out why the engine keeps dying. If the hybrid batteries are discharged, they must be properly recharged to prevent serious damage.

CAUTION: Read ALL service and warning lables in the engine compartment before attempting ANY type of service on a hybrid vehicle. The wiring harnesses that have ORANGE connectors are HIGH VOLTAGE connectors and can cause serious injury or death.

DO NOT touch any wiring harness or component that has a HIGH VOLTAGE warning label on it.

My recommendation is to tow the vehicle to a qualified hybrid repair center (preferably the dealer) and get it properly diagnosed and repaired. The high-tech, high voltage systems in this vehicle is nothing for anyone but a trained, certified technician to be messing with.

Go to an auto parts store and they will run a diagnostic test for you for free. It may be that the gas cap needs to be replaced. That was the case on my 2002 Toyota Avalon when the check engine light stayed on.
