When this light is on solid, the system will not limit wheel spin. Adjust your driving accordingly. Check your DIC messaging to determine whether it is because of the driver turning off the system, or that the system may not be working properly and your vehicle requires service. When this light is turned on, either the SERVICE TRACTION or TRACTION OFF message will be displayed. SEE DIC Warnings and Messages for more information on the messages associated with this light. To limit wheel spin, especially in slippery road conditions, you should always leave the ETS on. But you can turn the system off if you prefer.

Adding non-dealer/non-retailer accessories can affect your vehicle's performance. See Accessories and Modifications on page 5-3 for more information. Electronic Stability Control (ESC) Your vehicle may have an Electronic Stability Control (ESC) system which combines antilock brake, and traction and stability control systems that help the driver maintain directional control of the vehicle in most driving conditions. When the vehicle is started and begins to move, the system performs several diagnostic checks to ensure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. The system should initialize before the vehicle reaches 20 mph (32 km/h). If the system fails to turn on or activate, the ESC/TCS light comes on, and the ESC OFF and/or SERVICE ESC message displays.
