Another way was to disconnect the car memory disc and connect it again then car start as normal. Problem was the loose memory during the time i drive on across on rainfall flood.

Secondly engine check and abs sign remain appear on the screen these still existing to date although a car is running.

Take it back.

The camera is warning you that the shutter speed may be too slow for you to handhold the camera steady enough to prevent camera motion from blurring your photo.
For full details refer to the "Warning Messages and Displays" section of the manual (page 113 in my copy). If you need a manual you may download a copy here.

It is a Warning sign.
Warning sign - a sign giving warning of a hazard or danger (eg danger: electricity)

you mean abs not ads stands for anti brakeing system have your checked its throwing a code have fixed then light will go off its telling you somethings wrong somewhere in your brakes

I think its your handbrake warning sign...try to check your handbrake warning sign switch..may be the switch is shorted.

Could be the motor-management-warning light, but I guess it's the break-warning light. There might be too little breaking-fluid left in the lines ... A boardcomputer-readout should clarify this.

Otherwise, try parking on an ascending road with the nose pointing up, hit the hand-break and wait like 2 minutes; the light should come on. You might wanna retry it with the car's nose pointing downwards as well ... If so, definitely the breaking-fluid, otherwise probably not ;)

In any case - flashing warning light are never ok, so when you see it again and you're sure it's not just the ABS/ESP warning light, go and have your boardcomputer read-out, since it should contain useful errorcodes ..

I have same engine problem. Triangle signal pop up after I try to start my Prius with a still wet air filter to the car . The engine just run for less than 30 sec. and stopped with the triangle signe pop up. I think this sign will pop up whenever the engine detect certain major function failure. For my case, it was due to retricted air supply to the engine. I have tried Lovebytes suggestion and the triangle sign disappeared with a dry clean filter. My Prius is running good now. This warnig sign may have other implications. Once you try this method and sign still come on. You need to have your car check by garage.
Bellow attach is the answer from Lovebites

I had the same problem. I unplugged the relays from the fuse/relay box under the bonnet. (Top left side) and replaced them. The problem disappeared. (2001 Prius 109,000 miles)
