Traction Control System (TCS) The Traction Control System (TCS) is part of StabiliTrak. TCS limits wheel slip which is especially useful in slippery road conditions. The system operates only if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to limit wheel spin and also reduces engine power. The system may be heard or felt while it is working. This is normal and does not mean there is a problem with the vehicle. Notice: If the wheel(s) of one axle is allowed to spin excessively while the StabiliTrak, ABS and brake warning lights and any relevant DIC messages are displayed, the transfer case could be damaged. The repairs would not be covered by the vehicle warranty. Reduce engine power and do not spin the wheel(s) excessively while these lights and messages are displayed. TCS can operate on dry roads under some conditions. When this happens, the system may be heard working or a reduction in acceleration may be noticed. This is normal and does not mean there is a problem with the vehicle. Examples of these conditions include hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. 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 4-7. The message TRACTION FAULT appears in the Driver Information Center (DIC) when a TCS or Antilock Brake System (ABS) problem has been detected and the vehicle needs service. When this message is on, the system will not limit wheel spin. Adjust your driving accordingly. See DIC Warnings and Messages on page 4-37. The StabiliTrak/TCS light will flash on the instrument panel cluster when the TCS system or StabiliTrak is both on and activated. 5-8
