The "economy" mode is the standard mode, it is activated when driving at low speeds, it provides economical driving. When driving in the "sport" mode, the upshifts are engaged at a higher engine speed than in the normal mode. In the "winter" mode, when the car starts moving, the 2nd gear is automatically engaged, which provides the necessary traction of the wheels on a slippery road and reduces their tendency to slip.

The gearbox is controlled by the selector lever. The engine is started only when the selector lever is in the "P" or "N" position.
When the lever is in position "D", four gears are automatically shifted from low to high and vice versa (depending on engine load, driving conditions and speed).
In position "3" 1st, 2nd or 3rd gear is automatically shifted up and down depending on engine load and driving speed; 4th gear is not engaged.
In position "2" 1st or 2nd gear is automatically shifted up and down depending on the engine load and driving speed, 3rd and 4th gears are not engaged.
In position "1" the car moves only in 1st gear, 2nd, 3rd and 4th gears are not engaged. This achieves the maximum possible engine braking efficiency.
When operating a car with an automatic transmission, you need to know that the gearbox is lubricated only when the engine is running. Therefore, if you have to tow the car, you must do so with the drive wheels raised. It is prohibited to move with the ignition off. It is also prohibited to push the car to start the engine.
When operating the vehicle, the following requirements must be met:
- the battery must not be disconnected when the engine is running;
- when the ignition is on, you cannot disconnect the computer;
- before connecting any connector, check the condition of all connectors and terminals;
- check the condition of the mechanical lock;
- when checking electrical equipment, the battery must be charged;
- it is prohibited to use a power source with a voltage higher than 16 V;
- it is prohibited to use the test lamp.
