How to Read a Car's Speedometer?
2 Answers
The car speedometer consists of two dials, one is the speedometer, and the other is the odometer. The car speedometer is used to display the vehicle's speed, with the unit being km/h. Methods to identify the car's dashboard: The dial marked with ×100RPM or ×1000RPM is the tachometer, indicating XX revolutions per minute. Multiply the number pointed by the needle by the unit marked on the dial to get the current RPM. For example, if the needle points to 3 and the dial is marked ×1000RPM, then it is 3000 revolutions per minute. Self-check function of the car speedometer: At the moment of starting, the vehicle will activate the self-check function. At this time, the dashboard needles will swing to the maximum and then fall back, and various regular indicator lights will turn on for a few seconds before automatically turning off, which is the normal state.
I always locate the speedometer first, that round gauge right behind the steering wheel. The number the needle points to shows your current speed in kilometers per hour. Pay special attention when the needle hits 120 on highways. Don't stare at it while driving - just glance briefly. Taking your eyes off the road for more than 2 seconds is dangerous. Back when I drove older models, I noticed slight discrepancies - the GPS navigation would show 3-5 km/h slower than the speedometer at highway speeds, so now I always keep navigation on for reference. During regular maintenance, have the mechanic check the vehicle speed sensor. If the needle fluctuates erratically, get it fixed immediately. Many newer cars use digital LCD displays which are more intuitive - the numbers turn red when you exceed speed limits.
