STARTING DISABLED SERVICE THROTTLE This message displays if the starting of the engine is disabled due to the electronic throttle control system. Have your vehicle serviced by your dealer/retailer immediately. This message only appears while the ignition is in ON/RUN, and will not disappear until the problem is resolved. This message cannot be acknowledged. 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 3-45 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 5-71,Tire Pressure Monitor System on page 5-66, and Inflation - Tire Pressure on page 5-64 for more information. TIGHTEN GAS CAP This message may display 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 3-38. 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 4-5 for more information. 3-59
