Anti-Lock Brake System Warning Light; Low Tire Pressure Warning Light - Chevrolet 2004 Avalanche Owner's Manual

Anti-Lock Brake System Warning
Light
That's normal. If the light doesn't come on then, have it
fixed so it will be ready to warn you if there is a
problem.
If the light stays on, or comes on when you're driving,
your vehicle needs service. You will also hear a chime
sound when the light is on steady. If the regular brake
system warning light isn't on, you still have brakes, but
you don't have anti-lock brakes. If the regular brake
system warning light is also on you don't have anti-lock
brakes and there's a problem with your regular brakes. In
addition to both lights, you will also hear a chime sound
on the first occurrence of a problem and each time the
vehicle is shut off and then restarted. See Brake System
Warning Light on page 3-37.
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds.

Low Tire Pressure Warning Light

This light will also come on briefly when you turn the
ignition to RUN.
See "CHECK TIRE PRESSURE" under DIC Warnings
and Messages on page 3-60 for more information.
Stop and check your tires as soon as possible,
and inflate them to the proper pressure as indicated on
the vehicle's certification/tire label. See Tires on
page 5-64 for more information on your vehicle's tires.
This light and a chime will
come on along with the
CHECK TIRE PRESSURE
message in the DIC
when one or more of your
tires is significantly
under-inflated.
