If your vehicle is in cruise control when the TAS begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow you to safely use it again, you may turn the cruise control back on. See "Cruise Control" in the Index. When the TRACTION OFF light is on, the TAS is off and will not limit wheel spin. Adjust your driving accordingly. See "Traction Off Light" in the Index. The Traction Assist System, as delivered from the factory, will automatically come on whenever you start your vehicle. To limit wheel spin, especially in slippery road conditions, you should always leave the system on. But you can turn the TAS off if you ever need to. (You should turn the TAS off if your vehicle ever gets stuck in sand, mud, ice or snow. See "Rocking Your Vehicle" in the Index.) To turn the system on or off press the TAS on/off button located to the left of the steering wheel on the instrument panel. The TRACTION OFF light will come on under the following conditions: D The Traction Assist System is turned off, either by pressing the TAS on/off button or turning off the automatic engagement feature of the TAS. D The transmission is in FIRST (1); TAS will not operate in this gear. This is normal. D The vehicle is driven on a severely rough road. When the vehicle leaves the rough surface, slows down or stops, the light will go off and TAS will be on again. This is normal. D A Traction Assist System problem has been detected and the vehicle needs service. If you used the button to turn the system off, the TRACTION OFF light will come on and stay on. You can turn the system back on at any time by pressing the button again. The TRACTION OFF light should go off. 4-10
