Cadillac 2005 CTS - Manual (Page 169)

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on
for several seconds.
That’s normal.
If the ABS warning light comes on and stays on, there
may be a problem with the antilock portion of the
brake system. If the red BRAKE light is not on, you
still have brakes, but you don’t have antilock brakes.
See
Brake System Warning Light on page 3-42.
If the light stays on, turn the ignition to OFF. If the
light comes on when you’re driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you’re driving, your vehicle
needs service. 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.
See
Brake System Warning Light on page 3-42.
Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may
be a problem with the
traction control system.
The TC (traction control) warning light will come on
briefly when you turn the ignition to ON. If it doesn’t
come on then, have it fixed so it will be ready to warn
you if there is a problem.
The light will also come on if you turn the traction
control system off using the TC (traction control) on/off
button located in the glove box for the CTS and on
the steering wheel for the CTS-V.
If the TC (traction control) warning light stays on or
comes on while you are driving, pull off the road as
soon as possible and stop carefully. Try resetting
the system by turning the ignition off then back on.
