Brake system warning light.....
According to my 2000 Sienna manual, an exclamation point in a circle with 2 parens on either side is a brake system warning light. Might want to get your brake system looked at.
If your vehicle has separate dash panel warning lights for brakes and emergency brakes, then the e-brake light being on while not engaged may indicate that the e-brake switch may be maladjusted or faulty. If the brake warning light is on, it may indicate a brake fluid leak, or in some cases, low brake fluid levels in the reservoir. If your vehicle has a shared warning light for e-brake and brake warning, all causes listed above could apply.
If it is your emergency brake warning light, the switch that warns you that the brake is applied may be out of adjustment.HOWEVER - if it is your brake system warning light - GET IT LOOKED AT ASAP - The vehicle's on-board computer is sensing that there's something wrong with it.
Warning light usually indicates low brake fluid or parking brake not fully released
it means a brake-lamp bulb has burned out
somtimes float sticks down in brake master
Check brake fluid level in master cylinder Check to make sure parking brake is fully released
The brake light is controlled by a relay switch. If the relay switch is bad the brake lights will stay on. The brake light switch simply plugs in and out. Unplug the brake light switch until you can replace it.
The transit brake warning light, on a Ford, can be reset by changing the brake pads. If the warning light is still on after changing the brake pads remove the fuse for 10 seconds.

Check the brake fluid level, as on many vehicles the "emergency brake" (in the UK, Hand-brake) warning light also acts as a warning light for low brake-fluid.
