118 Instruments and Controls
The traction off light comes on when the
Traction Control System (TCS) has been
turned off. If StabiliTrak/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 0 214.
If TCS is off, wheel slip during acceleration is
not limited unless necessary to help protect
the driveline from damage. Adjust driving
accordingly.
