You have a failure in each of the systems listed, get the codes read, that should tell you where to start. Don't disconnect the battery attempting to reset the system as this can and does cause the system to totally shut down and then it has to be reflashed by the dealer to bring thing back to factory settings.

Ok, who 'reads' these codes?

Some parts stores can pull them, but your best bet is a shop, they can pull everything at one time, a parts store may only be able to do engine.

Did you end up getting it checked? What was the issue? This just happened to me today. All same 3 lights.

I hope this helps everyone dealing with this RAV4 mystery ... All 3 lights presented on my panel yesterday so I drove the car to the dealer. Dealer ran diagnostics and brought the following codes: P2401, P2402, P2419, P0456, P043F, P043E. Quoted nearly $2k for parts and repairs!!! I immediately began researching - best site is RAV4world.com I discovered that for the last 20 years Toyota has been selling us vehicles with faulty emission systems with a TSB (technical service bulletin) but no recall. Dealers are making a small fortune charging for anything from O2 sensors to a new emission system - and guess what? There's more! After investing all that $$$$ the lights may still come on at any time. My 2009 RAV4 has 32,000 miles on it and is paid off. I had intended to keep this car until the wheels fall off. Research your problem thoroughly! I became familiar with the following website

My lights also come on periodically. The shop told me it was a faulty wheel sensor which they replaced. It still comes on from time to time but it tends to reset itself after about 24 hours. Always seems to come on after long trips over rough roads.

Sorry, I meant to say I agree with Mrs. Maverick, after a lot of time and money the lights still come on.

Alice - it depends on which icons are lighting up on your instrument panel. In my case I had 3 - CEL, 4WD, and Trac. Toyota dealer diagnosed EVAP System failure - dealer quoted 2k to repair but after much discussion they contacted Toyota and got a goodwill repair for me. I paid them $300 for labor only to replace the Evaporative Emission system. But I only have 32,000 mi on my RAV & that's why Toyota gave me the parts. So ask for a print out of the codes that come from the diagnostic test and then research them on the forums for your car or google your car & the codes. In my case I needed a smog test by the end of November for lic plates and my car had to be repaired or it would have failed emission testing.
