Anti-Lock Brake System Warning Light - Chevrolet 2005 T-Series Owner's Manual

When the warning light comes on while you are driving,
you should drive only as far as the nearest point of
safety and then stop the vehicle. Here's a very important
thing for you to know:
CAUTION:
{
If the air brake system warning light comes on
and the warning tone sounds, the vehicle can
stop suddenly and without further warning.
This is because the parking brake will come on
if the pressure falls below 35 to 45 psi (240 to
310 kPa). You or others could be injured. If the
air brake system warning light comes on and
the warning tone sounds, stop as soon as you
can. You will not know how quickly the system
is losing pressure, so be aware that the
parking brake may come on suddenly.
Anti-Lock Brake System
Warning Light
If the light stays on, or comes on when you're driving,
your vehicle needs service. If the BRAKE or LOW
AIR warning light isn't on, you still have brakes, but you
don't have the anti-lock brake feature. If the BRAKE
and/or LOW AIR warning light is on, you don't
have anti-lock brakes and there's a problem with your
regular brakes. See Brake System Warning Light
on page 3-27 and Anti-Lock Brake System (ABS) on
page 4-6 for more information.
This light should come
on briefly when you start
the engine, if it does
not have your vehicle
fixed immediately.
