It maybe the information display is not in standard mode by some kind of diagnostic mode.

If you have raiod security code, disconnect the battery negative terminal for 30 mins and reconnect it to see if it can rest it.

I believe that symbol is Engine Oil if im not mistaken, might want to look at your oil level or take it in to a repair facility promptly

Unfortunately you probably have a blown headgasket. You should not drive the car like this as it will further damage the engine. The parts and labor for this job are not cheap. You may want to phone around and get some quotes. I would ask for prices on the headgasket, themostat, timing belt and waterpump. All these things should be done as part of the job.

Hope this helps,

Typcally caused by one of the front oxygen sensors or a bad ground associated with these sensors.Replace both front sensors with direct fit type NOT universal, because there may be a cracked wire and the universal sensor does not contain the complete wire harness. Direct fits, are about $20 more than universal fit type.

The O2 sensors have integrated heating elements that bring them up to the proper operating temperature. Code P0431 indicates that the O2 sensor on your driver side catalytic converter is not reaching the proper operating range. The O2 sensors are usually in the $150 range online.

change the flasher fuse. Also, check to see if any of your bulbs are burnt out. On most cars, this will cause the signals not to work properly.
