Traction Assist System (TAS) Your vehicle has a Traction Assist System (TAS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the rear wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power to limit wheel spin. The LOW TRAC light next to the button will come on when the TAS is limiting wheel spin. You may feel or hear the system working, but this is normal. The Traction Assist System may operate on dry roads under some conditions. When this happens, you may notice a reduction in acceleration. This is normal and doesn't mean there's a problem with your vehicle. Examples of these conditions include a hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. The TRAC OFF light on the button will come on under the following conditions: 0 The Traction Assist System is turned off, either by pressing the TAS on/off button or by turning off the automatic engagement feature of the TAS. The transmission is in FIRST (1) gear; TAS will not operate in this gear. This is normal. 0 The vehicle is driven on an extremely 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. A Traction Assist System, Anti-Lock Brake System or engine-related problem has been detected and the vehicle needs service. 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 re-engage the cruise control. See Cruise Control Light on page 3-40. When the TRAC OFF light on the button is on, the TAS is off and will not limit wheel spin. Adjust your driving accordingly. 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 shouid turn the TAS off if your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required. 4.- 9
