To turn off TCS and StabiliTrak, press and hold the StabiliTrak/TCS button until the TRAC OFF and STAB SYS OFF messages come on the DIC and the StabiliTrak/TCS light comes on the instrument panel. To turn TCS and StabiliTrak back on, press and release the StabiliTrak/TCS button. When the TCS or StabiliTrak system is turned off, the StabiliTrak/TCS light and the appropriate TRAC OFF or STAB SYS OFF message will be displayed on the DIC. The vehicle will still have brake-traction control when TCS or StabiliTrak is off, but will not be able to use the engine speed management system. The StabiliTrak/TCS light flashes when either system is actively working. See Traction Control Operation following for more information. 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 3-10. 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. 4-8
