Cadillac 2006 STS - Manual (Page 210)

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 engine on. If it does not 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 on the console.
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. Turn your engine off and
then restart it. If the light still stays on or comes back on
again while you are driving, your vehicle needs service.
Have the traction control system inspected as soon as
possible. See Traction Control System (TCS) on
page 4-9 and StabiliTrak
® System on page 4-11 for
more information.
Also see Competitive Driving Mode (STS-V) on
page 4-10 for more information.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine is very hot.
This light will also come on briefly when the vehicle
is started.
If the light does not go out or comes on and stays on
while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light on
could cause your vehicle to overheat, see Overheated
Engine Protection Operating Mode on page 5-32.
