Cadillac 2004 DeVille - Manual (Page 176)

Traction Control System (TCS)
Warning Light
This warning light should come on briefly when the
engine is started.
If the warning light does not come on then, have it fixed
so it will be ready to warn you if there is a problem. If
it stays on, or comes on when you are driving, there may
be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust
your driving accordingly.
The traction control system warning light may come on
for the following reasons:
• If there is a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on.
• If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
• If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
