When I had that problem with the emergency light it was the sensor for emergency brake
The abs and brakes sounds like you are loosing pressure in the system

The abs is part of the safety system in that it stops the wheels from locking up under heavy braking. This allows you to steer the vehicle out of a bad situation. During normal braking the ABS does not work as the wheels are turning and so there is no requirement for the system to work
If you wish to continue driving and are considerate in that you drive responsibly there is no need to race it to replace the system. I would seek a second opinion from an accredited brake specialist shop as the dealer may only want to sell parts and not repair the unit

Your owners manual should tell you

You have a fault in the ABS Braking System

Traction Control/Vehicle Stability Control
lights are part of that system

Have to get codes just like all vehicle problems,
when any light comes on & then diagnose system
down to a component & test that

I believe VSC in the warning lights is Variable Speed Controller. It should be dealing with the traction control. If that is malfunctioning your traction control system isn't working properly. essentially what this does is automatically control how your drive train applies power to the drive wheels in order to maintain control of the vehicle on the different terrains it is driven.

red triangle with ! is the vehicle stability control not the ebattery prolly a bad sensor

Acording the online manual , that is the Hybrid system warning light. I havn't tracked down exactly what it means , but is is grouped in with other service reminders. Will add more info when i find it " Google 2005 prius warning light " one of the first listings has a link to toyotapartsandservice.com

Can't find a BAS light in the manual , there is however a ABS light , which is a antilock brake system warning light . Check your tire presures before you check with the toyota service people.
ABS systems monitor the speed of the rotation of the tires , if one is low , the car sees it as a problem.
