TIGHTEN FUEL CAP This message may display and a chime may sound if the vehicle's fuel cap is not tightened properly. 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 allows fuel to evaporate into the atmosphere. This message remains on until it is manually cleared from the DIC display. The DIC message is also 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 3-41 for more information. TURN SIGNAL ON This message displays and a chime sounds if a turn signal is left on for 3/4 of a mile (1.2 km). Move the turn signal/multifunction lever to the off position. DIC Vehicle Customization Your vehicle may have customization capabilities that allow you to program some features to one setting based on your preference. All of the customizable options listed may not be available on your vehicle. Only the options available display on the Driver Information Center (DIC). The default settings for the customization features were set when your vehicle left the factory, but may have been changed from their default state since then. To change feature preferences, make sure the ignition is on and the vehicle is in PARK (P). To avoid excessive drain on the battery, it is recommended that the headlamps are turned off. Press the customization button to scroll through the available customizable options. After pressing the customization button, VEHICLE SETTINGS momentarily displays before going to a customization option. TRACTION CONTROL OFF This message displays 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 4-6. 3-58
