Its the parking brake light.
The parking brake light comes on when you engage the parking brake. Pull the parking brake release handle. ------------------------------------------------------------------------------- the brake light also comes on if the brake fluid level in the brake master cylinder is low ( in your engine compartment )
Is it the parking brake light or the ABS light? is it red light or amber?
In a 1996 Toyota Avalon, the parking brake light switch is typically located on the parking brake lever assembly. When the parking brake is engaged, the switch is activated, illuminating the warning light on the dashboard. You can usually find the switch mounted near the base of the parking brake lever. If you need to access it for inspection or replacement, you may need to remove the center console cover.
On a 2001 GMC Safari, the parking brake switch is typically located on the parking brake assembly itself, which is found under the dashboard near the driver's side. It activates the warning light on the dashboard when the parking brake is engaged. If you're having trouble locating it, checking the vehicle's service manual can provide more detailed information.
Low brake fluid in master cylinder? Parking brake not fully released?
The "P" in a circle on a vehicle's dashboard typically indicates that the parking brake is engaged. It serves as a reminder to the driver to release the parking brake before driving. If the light remains illuminated while driving, it may also suggest a potential issue with the braking system, warranting further inspection.
That typically means that your parking brake is on. It could just be a faulty sensor if your brake isn't on.
To turn off the parking brake, locate the parking brake lever or button in your vehicle. If it's a lever, pull it slightly and then release it to disengage; if it's a button, simply press it to deactivate. Ensure that the vehicle is in the "Park" position if it's an automatic transmission, or in neutral for a manual, before releasing the brake. Always check that the parking brake indicator light turns off on your dashboard.
Check the fluid level in the master cylinder.
