TIGHTEN GAS CAP This message may display and a chime may be heard along with the check engine light on the instrument panel cluster if the vehicle's fuel cap is not tightened properly. See Malfunction Indicator Lamp on page 3-34. Reinstall the fuel cap fully. See Filling the Tank on page 5-10. 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. A few driving trips with the cap properly installed should turn this light and message off. TRACTION CONTROL OFF If your vehicle has StabiliTrak, this message displays when the Traction Control System (TCS) is turned off. Adjust your driving accordingly. See StabiliTrak® System on page 4-6 for more information. TRANSMISSION HOT IDLE ENGINE 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 the transmission temperature warning is displayed. This message displays along with a chime if the transmission fluid in the vehicle gets hot. 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 clears and the chime stops when the fluid temperature reaches a safe level. TIRE LEARNING ACTIVE If your vehicle has the Tire Pressure Monitor System (TPMS), this message displays when the system is re-learning the tire positions on your vehicle. See DIC Operation and Displays on page 3-41 for more information. The tire positions must be re-learned after rotating the tires or after replacing a tire or sensor. See Tire Inspection and Rotation on page 5-70, Tire Pressure Monitor System on page 5-65, and Inflation - Tire Pressure on page 5-63 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. 3-56
