Speedometer and tachometer

The speedometer shows the speed of the movement of the car in km/h; the tachometer shows the frequency of rotation of a bent shaft of the engine in thousands of rpm and is intended for control over engine turns – the arrow should not enter a red zone of a scale.

Earlier switching to the raising transfer allows to save fuel and to reduce noise of the power unit. In the period of a running in of the car it is necessary to avoid too high turns of a bent shaft. At achievement of critical turns of a bent shaft the control system automatically interrupts fuel supply that is followed by sudden loss of power.

Index of fuel consumption

The index of fuel consumption is intended for visual representation of fuel consumption (l/100 to km), allowing to draw conclusions about profitability of style of driving. At the motionless car of the shooter of the index is on zero.

The index of a reserve of fuel and To/L use of a reserve of fuel

The index of a reserve of fuel serves for visual monitoring of a reserve of the fuel remaining in a tank. The error of indications of the index of a reserve of fuel is minimum when the car holds strictly horizontal position, and increases at movement of the car along twisting or hilly roads. The index works at the included ignition. At entry of the index into a zone of a reserve reserve of fuel joins corresponding To/L. At the same time follows at the first opportunity to make refueling of the car. To/L also joins at inclusion of ignition and through short time has to go out, pointing out serviceability of the index of a reserve of fuel. If To/L it is not switched off, in a tank there was a reserve volume of fuel.

The nullified counter of a run and the odometer

The nullified counter of a run allows to control a car run, since the moment of dumping of its indications (for example, for the current trip). To nullify the counter, at the lock of ignition which is in situation "1" or "2" press the dumping button (An arrangement of instrumentations).

The odometer is intended for the indication of a full run of the car.

The index of temperature outside of the car

This index works already at turn of a key in the ignition lock in situation "1". If in this position of the ignition key to press the dumping button (An arrangement of instrumentations) and, holding it, to turn the ignition key in situation "0", there is a switching of units of measure of temperature. At decrease in temperature approximately to 3 °C, for the purpose of the warning of a possibility of ice of the indication of the thermometer begin to blink, and the sound signal is distributed. The prevention repeats until temperature increases to 6 °C.

Index of temperature of OZh and KL of an overheat of the engine

It is intended for visual representation of temperature of OZh for the purpose of prevention of damage of the engine. To/L an engine overheat, built in the index, lights up at inclusion of ignition and through short time has to go out, pointing out serviceability of the index. If the arrow of the index is in a blue zone, i.e. the engine is not heated-up, avoid the movement at a high speed and high turns of the engine. At entry of an arrow of the index into a red zone of a scale lights up To/L an overheat of the engine and/or on the text display in a combination of devices the message of "COOLANT TEMPERATURE" is displayed. It indicates an engine overheat – switch off the engine and let's it cool down. Check the OZh level and tightness of the cooling system (see the Head Nastroyki and routine maintenance of the car). Eliminate the found malfunctions. Normal range of working temperatures of the engine is the area between blue and red zones on the dial of the index of temperature of OZh.

The text display in a combination of devices
