TIGHTEN FUEL CAP If the vehicle's fuel cap is not tightened properly, this message may appear along with the check engine light on the instrument panel. Reinstall the fuel cap, making sure to fully install the cap. See Filling Your 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. A few driving trips with the cap properly installed should turn the light and message off. TRANS HOT IDLE ENGINE If the transmission fluid in the vehicle gets hot, this message will appear on the DIC and you will hear a chime. The chime will stop when the transmission fluid temperature is less that 265°F (129°C). Driving with the transmission fluid temperature high can cause damage to the vehicle. Stop the vehicle and let it idle to allow the transmission to cool. This message will clear when the fluid temperature reaches a safe level. See Transmission Temperature Gage on page 3-46. Notice: If you drive your vehicle while the transmission fluid is overheating and the transmission temperature warning is displayed on the instrument panel cluster and/or DIC, you can damage the transmission. This could lead to costly repairs that would not be covered by your warranty. Do not drive your vehicle with overheated transmission fluid or while transmission temperature warning is displayed. TRACTION ACTIVE When the traction control system has detected that any of the vehicle's wheels are spinning, the traction control system will activate and this message will appear on the DIC. For more information, see Traction Assist System (TAS) on page 4-9. TRACTION SYS LIMITED If the brake traction control system activates constantly or if the brakes have heated up due to high-speed braking, brake traction control will be displayed and the TRACTION SYS LIMITED message will be displayed. The system will return to normal operation after the brakes have cooled. 3-68
