The layout of the meters of the instrument cluster
1 - Fuel gauge; 2 - Speedometer; 3 - Odometer; 4 - Tachometer; 5 - Coolant temperature gauge; 6 - Button for resetting the mileage meter; 7 - Vehicle mileage meter since reset
Tachometer
The tachometer shows the engine speed in thousands of revolutions per minute. In order to avoid engine failure, it is forbidden to exceed the maximum permissible speed of the crankshaft (the tachometer needle should never enter the red zone of the scale).
Speedometer
The speedometer shows the speed of the vehicle. The unit of measure is usually km/h. in some cases, two scales may be applied to the dial of the meter: km / h and miles / h. Sometimes the vehicle may be equipped with a signal buzzer for exceeding the permissible safe speed (120 km/h).
Tank gauge

And — a Control lamp of a reserve stock of fuel
The device registers the current amount of fuel in the tank. The error in the meter readings is minimal when the car is in a strictly horizontal position. When driving on winding or hilly roads, the error of the instrument increases. The functioning of the meter does not depend on the position of the ignition key. Label F corresponds to the state of full refueling, E - to an empty tank. Pilot lamp built into the dial (A) notifies the driver of the need to refuel the vehicle as soon as possible.
Engine coolant temperature gauge
A - Overheating zone label
The device records the temperature of the engine coolant. The normal operating temperature of the engine during normal operation of the vehicle corresponds to the middle position of the pointer. Under severe operating conditions, such as very hot weather or long uphill climbs, the pointer may rise to the upper red mark on the scale (H). If the engine temperature has increased so much that the pointer needle enters the red range of the meter scale (mark A), stop driving immediately, pull over to the side of the road, park the car and check the condition of the cooling system to determine the causes of engine overheating (see chapter Settings and ongoing maintenance).
Odometer
The odometer records the total mileage of the vehicle in kilometers or miles, depending on the version.
Odometer/outside temperature gauge
The meter records the vehicle's current mileage since the last reset (in kilometers or miles, depending on the version). The meter readings are reset using a special button mounted in the instrument panel to the left of the speedometer assembly.
