Instrument Cluster Many lights will illuminate when you start your vehicle to make sure the bulbs work. If any light remains on after starting the vehicle, have the respective system inspected immediately. If your vehicle is equipped with a diesel engine, it has a unique cluster; refer to Starting the engine in your 6.0 Liter Power Stroke Direct Injection Turbo Diesel Owner's Guide Supplement. Service engine soon: The Service engine soon indicator light illuminates when the ignition is first turned to the ON position to check the bulb. Solid illumination after the engine is started indicates the On Board Diagnostics System (OBD-II) has detected a malfunction. Refer to On board diagnostics (OBD-II) in the Maintenance and Specifications chapter. If the light is blinking, engine misfire is occurring which could damage your catalytic converter. Drive in a moderate fashion (avoid heavy acceleration and deceleration) and have your vehicle serviced immediately. Under engine misfire conditions, excessive exhaust temperatures could damage the catalytic converter, the fuel system, interior floor coverings or other vehicle components, possibly causing a fire. Electronic throttle control: Illuminates when the engine has defaulted to a 'limp-home' operation. Report the fault to an authorized dealer at the earliest opportunity. On vehicles equipped with a message center, "ENGINE FAILSAFE MODE" will be displayed, refer to Message Center in the Driver Controls chapter. 13 2007 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
