Red exclamation light on - 2005 Toyota Prius

It is called Master Warning sign. Get the car be scanned to know about the root cause of the problem.

Look in your owners manual

Can also find those symbols on the internet

air pressure

man this one was a challenge. however i did learn that this vehicle is autralian. pretty cool i might add. however the symbal is basically the same thing as a check engine light. took me 2 hours to find that answer for ya.

I already found the owner manual on the internet. thanks for helping me out.

It's either a broken hand brake light sensor of your brake pads needs to be replaced.

Look to see if you have a loose tailgate door.

Normally,,,the exclamation mark in car dash board defines the "Handbrake"...if you pull the hand brake lever up it lights on...sometimes there can be problems with that switch(all time it can be in on)...
