Traction Control System (TCS)/
StabiliTrak Light
This light comes on briefly when the vehicle
is turned on to show that the light is
working. If it does not come on then, have
it fixed so it will be ready to warn you if
there is a problem.
If the light is on and not flashing, the TCS
and potentially the StabiliTrak/ESC system
are not fully operational and may not assist
in maintaining control. Adjust driving
accordingly. If the condition persists, see
your dealer as soon as possible. A Driver
Information Center (DIC) message may
display.
The light flashes when the TCS and/or the
StabiliTrak/ESC system is actively working.
