Speedometer = Speed in MPH (US) or KPH (metric) Tachometer = Engine RPM's (revolutions per minute) how fast is the engine crank shaft spinning. Always stay below the red line area. Fuel = Indicates how much fuel you have in the fuel tank. Temp = Tells you the engine water temperature. Volts = tells you the status of your electrical system. Nominal will be 12-13 volts, 14+ volts tells you the system is charging and less than 12 volts indicates you are discharging. Any others you have that you need to know about?
Change the trip gage to how many miles are on the car on the dash.
