Low Traction Light (If Equipped) If you have the Traction Assist System, this light will come on when the system is limiting wheel spin. See "Traction Assist System" in the Index. You may feel or hear the system working or notice a lack of accelerator response, but this is normal. The LOW TRACTION light also comes on briefly when you turn your ignition to RUN. If the light doesn't come on then, the system may require service; have it fixed so it will be there to tell you when the Traction Assist System is active. Slippery road conditions may exist if the LOW TRACTION light comes on, so adjust your driving accordingly. Traction Off Light (If Equipped) If you have the Traction Assist System, this light should come on briefly when you turn the ignition to RUN. If the light doesn't come on then, the system may require service; have it fixed so it will be there to warn you if the system is turned off. If the TRACTION OFF light stays on, or comes on when you're driving, there may be a problem with your Traction Assist System and your vehicle may need service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. 2-92
