if low PSI warning comes on, you need to get vehicle off the road. low PSI means u have low air, or an air leak. this also means you are going to run out of air that operates the brakes
when this happens, the brakes lock on and you ain't going anywhere
warning will come on with enough time to get vehicle to side of road
if you drive a 379 pete and the warning is on and your psi is normal. check the low air switches they are behind the pannel in front of the clutch and brake pedal they are usually corroded
AnswerIt depends on WHEN the low PSI warning light came on.
If I was driving and the light came on, that means one of two things: I've got a massive leak somewhere in the air system and it just happened, or the belt to the air compressor broke AND I've got a leak in the system. In either case, pull over before your spring brakes activate. Those will stop you, but they won't turn the brake lights on so there's a chance you'll get rear-ended. Once you're stopped, shut down, get out and listen for the hissing sound. (Most people who get this light while driving ran over a recap, so try to Dodge those, okay?)
If it came on while I'm backing into a really complex hole that needs a lot of braking, that's normal. I'd just put the truck in neutral and rev it up a little to build some pressure in the brake system.
To notify the driver that there is a problem with the brake system.
This light warns that there is a problem somewhere in your anti-lock brake system. If the light comes on while you are driving, have your vehicle checked by a Toyota dealer asap. The light comes on when the ignition key is turned to the ON position. After 3 seconds it should go out. When the "ABS" warning light is on (and the brake system warning light is off), the brake system operates conventionally but anti- lock brake system is not assiting brake performace so that the wheels can lock -up during sudden braking or braking on slippery road surfaces. Vehicles with rear differential lock system- The anti-lock brake system does not operate when the rear differential is locked. It is normal operation for the "ABS" warning light to be on at this time.

Why is my 97 mercedes e420 abs and esp warning light on?
If the handbrake is not engaged, and the warning light is coming on, it may mean that there are components in the braking system that require maintanence. Or, it could mean that the master cylinder is low on brake fluid.
