Instrument Cluster Harley-Davidson vehicles Warning lights and gauges can alert you to a vehicle condition that may become serious enough to cause expensive repairs. A warning light may illuminate when a problem exists with one of your vehicle's functions. Many lights will illuminate when you start your vehicle to make sure the bulbs work. If any light remains on after starting the vehicle, refer to the respective system warning light description for additional information. Note: Some Warning Lights are reconfigurable telltale (RTT) indicator lights and will illuminate in the Message Center Display and function the same as the warning light. Service engine soon: The Service engine soon indicator light illuminates when the ignition is first turned to the RUN 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. 13 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
