See Figure 1. Five warning lamps are located on the right side of the instrument cluster. The warning lamps illuminate briefly when the ignition is first turned on. If lamps remain lit, begin flashing, or turn on after the initial diagnostics, the vehicle has a condition that will require attention.
When a warning lamp is illuminated, the LCD screen will display the condition.
Low Fuel Lamp
The amber low fuel lamp (1) illuminates when there is approximately 3 L (0.8 USgal) of gasoline left in the tank.
When the low fuel warning lamp illuminates, the low fuel odometer (F-trip) is activated and counts mileage traveled after low fuel warning lamp illumination. See Controls and Indicators → Odometer Functions for more information.
Check Engine Lamp
The amber check engine lamp (2) indicates whether the engine management system is operating normally. When an engine malfunction is detected, a check engine message is displayed on the LCD screen.
The check engine lamp illuminates briefly when the motorcycle's ignition is first turned on. At this time, the engine management system runs a series of self diagnostics.
If the lamp remains continuously lit after the initial diagnostics, begins flashing, or turns on at a later time, see a Buell dealer. This indicates an event has occurred related to the proper operation of the engine management system.
Engine Over Temperature Lamp
The red engine over temperature lamp (3) illuminates when the coolant temperature is above the normal operating range. When a temperature condition exists, the coolant temperature also flashes on the LCD screen. See Controls and Indicators → Coolant Temperature.
See Maintenance and Lubrication → Coolant Level: Buell 1125 Models to check the coolant level. If the level is adequate and temperature condition persists, see a Buell dealer for service.
Oil Pressure Lamp
The red oil pressure lamp (4) illuminates when oil is not circulating at the proper pressure through the engine.
NOTE
The oil pressure lamp will illuminate briefly when the ignition is turned on prior to starting engine.
Conditions that could cause the red oil pressure indicator lamp to illuminate during operation include:
- Incorrect oil level or diluted oil.
- Oil line clogged with ice and sludge, preventing oil circulation (in freezing weather).
- Grounded oil pressure switch wire.
- Faulty oil pressure switch.
- Damaged or improperly operating bypass valve.
- Improper oil pump operation.
NOTICE
If the oil pressure indicator lamp remains lit, always check the oil supply first. If the oil supply is normal and the lamp is still lit, stop the engine at once and do not ride further until the trouble is located and the necessary repairs are made. Failure to do so may result in engine damage. (00157a)
If the oil pressure lamp illuminates during operation:
- Stop the engine immediately and check the oil level.
- Add recommended oil as required until proper level is achieved.
If the oil pressure indicator lamp illuminates during operation despite proper oil level:
- Stop the engine immediately and do not ride further until the necessary repairs are made. See a Buell dealer.
Low Battery Voltage Lamp
The red low battery voltage lamp (5) illuminates when the battery voltage falls below 11.5 V. When a battery condition exists, a SYSTEM VOLTAGE message is displayed on the LCD screen.
If the lamp remains lit or turns on after the initial diagnostics, check the battery voltage and charge the battery if necessary. See Maintenance and Lubrication → Battery: Buell 1125 Models.
See a Buell dealer if problems with the charging system are suspected.
