The warning light is orange in colour, it looks like a set of brackets with two arrows in them pointing at a dot. There is a zigzag line joining the brackets at their bottom. What does this sign mean ?

You need to refer yo your owners manual, It is a WARNING light, your dealer can tell you the problem for free but fixing it is a different issue

Hey Elle, did you ever work out what it is? I have the same problem, and I don't have a service manual. I can't find it online, and the symbol doesn't appear in the Corolla manual. I've never seen anything like it.

Refer to your owner's manual, it will be listed there, every vehicle is different. Sounds like possible low coolant light.

Hello! It's the Tire Pressure Monitor light...One of the vehicle's tires is low on pressure...

ARROW POINTING DOWN THAT A LOW COOLANT WARNING LIGHT.THIS WARNING MEAN ADD COOLANT QUICK AS POSSIBLE OR THERE WILL SEVERE ENGINE DAMAGE.

It sounds like it's the low coolant level light. Check the overflow tank and fill to level indicated on side of tank.

have you rotated the wheels by any chance??had new tyres fitted??

its a low tire pressure light. check all tires and set to the factoy specs that are listed on the drivers door post. drive at a speed over 25mph for a little and the light should go off.

Malfunction indicator light it is the symbol of your engine with a line of suffering and the word "CHECK" -- this could be something minor like needing a spark plug to be replaced (common problem) or to something more serious like engine electrical work needed. a flashing engine light is the more serious so you are not to worry.
