The far left orange dashboard light?

sounds like low fuel light ! does it come on when 'fuel thing ' is pointing low ?

that warning light is the message given to you by the vehicle ECU,and by using a scanner surely you will get the fault code given.

Any time you get a light on the dash,of any vehicle ,you need to check your owners manual.
Next ,you need a code reader or better yet,a scan tool hooked to the vehicles diagnostic connector, under the dash to check for codes. I am really suprised at the hundreds,if not thousands of people that don't know that.
The vehicle symptoms will be found, after your have a code(if any) and follow some type of testing proceedure.

It means that the car it's having a problem and it's giving a troublecode to be analysed easier.

the light means check engine take it to get it looked at by a mechanic and tell him what happens

This light is for multi funtion automatic transmisson cooling system

Transmission warning light :)

that light is the engine warning light you should go and have your car checked over at a garage running very low on oil can cause some serious problems with your engine. you'll also have to go to a garage to get them to turn your light off.
