Anti-Lock Brake System Warning Light; Traction Off Light - GMC Yukon Denali 2006 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 3-35.

With the anti-lock brake
