If cruise control is being used when TCS begins to limit
wheel spin, the cruise control automatically disengages.
The cruise control can be re-engaged when road
conditions allow. See
Cruise Control on page 4 ‑ 8 .
SERVICE TRACTION CONTROL comes on in the
Driver information Center (DIC) when a Traction Control
System or Antilock Brake System problem has been
detected and the vehicle needs service. See
DIC
Warnings and Messages on page 4 ‑ 52 . When this
message is on, the system will not limit wheel spin.
Adjust your driving accordingly.
The traction control system automatically comes on
whenever the vehicle is started. To limit wheel spin,
especially in slippery road conditions, the system
should always be left on. But the traction control system
can be turned off if needed. It may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice,
or snow, and you want to
“ rock ” the vehicle to attempt to
free it. See If Your Vehicle is Stuck in Sand, Mud, Ice,
or Snow on page 5 ‑ 35 .
To turn the system off,
press and release the
TCS button.
This light will come on
steady when the traction
control system has been
turned off. This light
flashes when TCS is
active.
If the TCS button is pressed, the traction control system
will turn off and a TRACTION CONTROL OFF message
will appear on the DIC. Press the TCS button again to
turn the system back on. The TRACTION CONTROL
OFF message will then go off. The Traction Control
System will reset itself at each ignition cycle.
Adding non ‐ dealer/non ‐ retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications on page 6 ‑ 4 .
