These gauges display to the driver how much fuel the engine has left, how fast the car is going, how hot the engine is, and how many RPM (revolutions per minute) the engine is clocking.
The speedometer is probably the most important dashboard display in the car. It tells you how fast your car is traveling, in either miles per hour (mph) or kilometers per hour (kph). The RPM gauge tells you how hard your engine is working. Most RPM gauges will have red areas starting at 6,000 or 7,000 RPM. When the dial in the gauge, travels into the red, learn to ease off the acceleration. The fuel gauge tells you how much fuel your car has left. It usually has a dial, like the hand of a clock that travels between "F" and "E," with "E" signaling "empty" and "F" signaling "full." Some more modern cars have digital fuel gauges; where electronic bars are displayed like the battery symbol on a mobile phone, and gradually decrease in quantity depending on how much fuel is in the car. The temperature gauge in the car tells you whether your car's engine is overheating. It usually has a dial that travels between "H" and "C," signaling "hot" and "cold." Your dial should normally be in the center of the gauge.
