The traction control system is enabled every time your vehicle is started. The system will activate if it senses that any of the wheels are spinning or beginning to lose traction. You may hear or feel the system working or notice a lack of accelerator response, 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. 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 on page 3-10. When the traction off light is on, the TAS is off and will not limit wheel spin. Adjust your driving accordingly. The traction off light will come on under the following conditions: • The Traction Assist System is turned off, either by pressing the TAS on/off button, located on the instrument panel, or by turning off the automatic engagement feature of the TAS. • The transmission is in FIRST (1); TAS will not operate in this gear. This is normal. • 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 turn 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 the vehicle has been driven with the TAS system on for long periods of time, or if the vehicle has gone through many several high speed braking maneuvers the system may be automatically disabled. The system will automatically re-enable after approximately two minutes of not using the brakes. See Traction Off Light on page 3-41. 4-9
