Light coming on. arrow pointing down with wavely lines above and below it. What does it mean?

When your car is cold, check your radiator or radiator overflow to see if you are low on fluid. I believe that is what that light means.

For a good measure I would check all of your fluids.

prestone low coolant missing wait untill the engine is cold open radiator cap refill the missing prestone start the engine will get warmmer and wait untill the radiator cooling fan start recheck the coolant close the cap and light should be off thank you pierre

That's the low coolant light. Looks like an arrow pointing at little waves. Get some coolant in that car asap!

means you are low on coolant

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.

yes according to cevy owners manual tis is te low coolant light

traction controll issues

The red warning light is a box with two waves in it, an arrow pointing down and a T on the top indicates your Engine Coolant is low.

Thats your low water light.If your water is full then you have a faulty switch.

check your manual or call service dept and ask, sometimes they are really good, if you get a bad representative call a different dealer
if you provide year it would be helpful when posting.
