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 diganostic 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. TRANSMISSION HOT If the transmission fluid temperature becomes high, the message center will display this message. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. When the transmission fluid temperature returns to normal, the display will turn off and the transmission shifting patterns will return to normal. 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 disabled and the TRACTION SYS LIMITED message will be displayed. The system will return to normal operation after the brakes have cooled. 3-75
