SERVICE TRANSMISSION This message displays when there is a problem with the transmission. See your dealer/retailer for service. THEFT ATTEMPTED This message displays if the content theft-deterrent system has detected a break-in attempt while you were away from your vehicle. See Content Theft-Deterrent on page 118 for more information. SERVICE VEHICLE SOON This message displays when a non-emissions related malfunction occurs. Have the vehicle serviced by your dealer/retailer as soon as possible. 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 226. Reinstall the fuel cap fully. See Filling the Tank on page 390. 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.

Have your vehicle serviced by your dealer/retailer. STARTING DISABLED SERVICE THROTTLE This message displays when your vehicle's throttle system is not functioning properly. Have your vehicle serviced by your dealer/retailer. 253
