hey there, i think i may have been having a blonde moment. what i believe to be a warning light i think is not a warning light and may have been there the whole time i just never took that much notice until i added the solution. i then panicked thinking i had done harm to then engine then good.  
  
im struggling on how to upload a pic.  newbie to the site.  
  
if you look on the zs dash you will see the petrol gauge with a petrol filler symbol on the opposite side you see the the oil coolant gauge with a symbol a thermometer with two lines under it. i didnt think that symbol should of been there but on further investigation it seems it is just a symbol that has been there the whole time.  
  
i hope this makes sense.
