2015 Kawasaki Vulcan S — Owner's Manual
ABS indicator may go on: After continuous riding on a rough road. When the engine is started with the stand raised and the transmission engaged, and the rear wheel turns. When accelerating so abruptly that the front wheel leaves the ground. When the ABS has been subjected to strong electrical interference.
When tire pressure is abnormal. Adjust tire pressure. When a tire different in size from the standard size is being used. Replace with standard size.
When the wheel is deformed. Replace the wheel. The speedometer is digital and can be set for km/h or mph. The unit setting can be changed according to local regulations.
Make sure the unit setting (km/h or mph) is correctly displayed before riding. Refer to the Unit Setting in the Display Setting section. The tachometer shows the engine speed in revolutions per minute (r/min, rpm). When the ignition switch is turned on, the tachometer needle momentarily sweeps from the minimum to the maximum reading, then back the minimum reading to check its operation.
If the tachometer does not operate correctly, have it checked by an authorized dealer.
