I dont know what the red circle with the line across meams.my car is a 2001 volksmagen jettan.

That's called the vacuum control valve.

That round light is the security/ theft prevention.

Are you check in the owners manual? Could be Fog Lights (Im not sure).

Keep us updated.

nvm i think i found em; if its a circle with 3 little sections on each side, it means have the brake pads checked

Check your coolant level in the overflow as well as the radiator. Be sure to only check the level with the engine cold. The system is under pressure and removing the cap when hot could cause sever burns and injuries. If you have to fill it be sure to use a 50/50 mix of dexcool and water.

rear defrost on?

this is very common problem, theres a vacuum leak.check the vacumm lines under the hood also check the one that goes inside to heater controls, whats happening is that it looses vacuum when you accel because the motor takes it,theres a one way valve that holds the vaccum when this happens but with a leak it cant hold vacuum,heres a vacuum diagram to help you check the vacuum lines,i dont know which engine you have in that 150 but this will be close. take good look at the circled areas in the diagrams,good luck, hope this helps you.

check your handbook for all dash lights.some are important.....(you dont say what colour)red is danger/yellow is info...

I have a red circle with a wave across the message

Red lights are always a warning of some kind. In this case you don't mention the make or model of car but I'm willing to bet it means the water level is low. Check the coolant level or the washer bottle level.
