Dashboard reading is a term used to describe the process of monitoring the various instruments and gauges located on the dashboard of a vehicle. This includes the GAUGE, tach, DIAL, and ODOMETER, all of which provide important information about the vehicle's performance. The GAUGE measures the pressure of the engine, the tach measures the speed of the engine, the DIAL measures the temperature of the engine, and the ODOMETER measures the total distance traveled by the vehicle. By regularly checking these readings, drivers can ensure that their vehicle is running safely and efficiently.
