TIGHTEN FUEL CAP If the vehicle's fuel cap is not tightened properly, this message may appear on the DIC and a chime will sound. Fully reinstall the fuel cap. See Filling the Tank on page 5-8. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. The DIC message will remain on until the message is cancelled with the return button on the steering wheel. The DIC message will also be cancelled if the ignition is turned off. The DIC message and the Service Engine Soon light may come on again during a second trip if the fuel cap is still not tightened properly. See Malfunction Indicator Lamp on page 3-42 for more information. TRACTION CONTROL OFF The TRACTION CONTROL OFF message will be displayed when you momentarily press the StabiliTrak® button located on the transmission shift handle. In this mode, stability control and the brake-traction control are functional. Engine speed management will be modified and the driven wheels can spin more freely. For more details on this mode, see StabiliTrak® System on page 4-9. TURN SIGNAL ON If a turn signal is left on for 3/4 of a mile (1.2 km), this message will appear on the display and you will hear a chime. Move the turn signal/multifunction lever to the off position. Press the select button to acknowledge this message and clear it from the DIC display. 3-59
