Check your Coolant Level, it is probably low.

look in your manual, it is in the glove box. the coolant in your reservoir is low, meaning the cooling system may be in jeopardy.

That is your low coolant level light. Add antifreeze/water mixture to the overflow resevoir

the light means that your coolant level is low. after the car has sat for long enough to cool down remove the radiator cap and ad 50/50 mixture antifreeze till full. start car and ad more as required. check for visible leaks.

USUALLY THAT MEANS YOUR LOW ON COOLANT. IF YOUR NOT LOW AND STILL STAYS ON THE SWITCH IS BAD

Triangle with downward arrow is Coolant level.

It may be the temperature light. It's hard to say by your description. Take a look inside the owner's manual to confirm.

that means you need to put coolant into ur reservoir.
