Engine Coolant Temperature Warning Light - Buick Regal Owner's Manual

If the light does not come on, have
the vehicle serviced by the dealer.
If the system is working normally,
the indicator light turns off.
If the light is on while certain DIC
messages display, this indicates
that the TCS and StabiliTrak
systems are not working or are
disabled.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. Check
the DIC messages to determine
which feature(s) is no longer
functioning and whether it is
because of the driver turning off the
feature(s), or because the system is
not working properly and the vehicle
requires service.
If the TCS is disabled, wheel spin is
not limited. If the StabiliTrak system
is disabled, the system does not aid
in maintaining directional control of
the vehicle.
If the indicator/warning light is on
and flashing, the TCS or the
StabiliTrak system is actively
working.
