This light comes on when the
Electronic Stability Control (ESC)
system is turned off. If the Traction
Control System (TCS) is off, wheel
spin is not limited. If the ESC is off,
the system does not assist in
controlling the vehicle. Turn on the
TCS and the ESC and the warning
light turns off.

Electronic Stability
Control (ESC)/Traction
Control System (TCS)
Indicator/Warning Light
The Electronic Stability Control
(ESC)/Traction Control System
(TCS) Indicator/Warning Light
comes on briefly when the engine is
started.
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 ESC and TCS are not
working or are disabled.
If the light is on and not flashing,
the TCS and potentially the ESC
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 ESC 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 ESC
system is actively working. Check
the DIC messages for details to
determine which system is working.
If the LOW TRACTION message
appears, the system is limiting
wheel spin. If the ESC ACTIVE
message appears, the system is
aiding in maintaining directional
control of the vehicle.
