Mode «economy» - This is the standard mode, turns on when driving at low speeds, provides an economical ride. When driving in «sport» upshifting occurs at a higher engine speed than in normal mode. In mode «winter» when starting the car, 2nd gear is automatically engaged, which provides the necessary grip of the wheels on slippery roads 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 position «P» or «N».
When the lever is in position «D» four gears switch automatically from low to higher and vice versa (depending on engine load, driving conditions and speed).
Pregnant «3» automatically shifts up and down 1st, 2nd or 3rd gear depending on engine load and speed, 4th gear does not engage.
In position «2» automatically shifts up and down 1st or 2nd gear depending on engine load and 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 included. This achieves the highest 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 a car, then you need to do this with the drive wheels raised. It is forbidden to move with the ignition off. It is also forbidden to push the car to start the engine.
When operating a vehicle, the following requirements must be met:
- when the engine is running, the battery must not be disconnected;
- 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 interlock;
- when checking electrical equipment, the battery must be charged;
- it is forbidden to use a power supply with a voltage higher than 16 V;
- do not use a test lamp.
