Traction Off Light

This light comes on briefly when the vehicle
is turned on. If it does not, have the vehicle
serviced by your dealer. If the system is
working normally, the indicator light then
turns off.
The traction off light comes on when the
Traction Control System (TCS) has been
turned off. If Electronic Stability Control
(ESC) is turned off, TCS is also turned off. To
turn TCS and ESC off and on, see Traction
Control/Electronic Stability Control 0 247.
If TCS is off, wheel spin is not limited unless
necessary to help protect the driveline from
damage. Adjust driving accordingly.
