GENERAL INFORMATION

The situation "R" – parking ("Parking")

In this situation back wheels are fixed. The automatic transmission is blocked by the ratchet mechanism which is not allowing its shaft to rotate. Installation of the lever of gear shifting in the situation "R" is possible only at the motionless car.

The situation "R" – a backing

Installation of the lever of gear shifting in the situation "R" is possible only at the motionless car. Even at very small speed of movement it is necessary to stop the car and only then to include backing transfer.


Prevention

It is impossible to try to rearrange the gear shifting lever in the situation "R" at car movement forward and in situation "1", "2" or "D" at car movement back.


The situation "N" – neutral situation

In this position of the lever of gear shifting the drive is disunited. The working engine does not actuate the car. The carburetor of the engine is equipped with the automatic starting arrangement which after its start holds the accelerated idling of the engine during its warming up.

At installation of the lever of gear shifting from the situation "N" in situation "1", "2", "D" or "R" the car tends to move a little. Therefore before installation of the lever of gear shifting in one of these provisions it is necessary to press a brake pedal.

Situation "D" – automatic gear shifting at advance

When finding the lever of gear shifting in this situation the car begins movement on the 1st transfer, and switching on the 2nd and 3-юю transfers occurs automatically depending on speed of movement of the car, and also level of opening of a butterfly valve in the carburetor (the provision of a pedal of an accelerator). Gear shifting on more lowest occurs also automatically. The pressing of a pedal of an accelerator against the stop and deduction in this situation during a short period (kick-down) causes it, depending on speed of movement, switching from the 3rd transfer on the 2nd or with the 2nd on the 1st, i.e. on more lowest transfer.

In the course of engine warming up when it works with the raised number of turns of idling, the car tends to a slow troganiye from a place at installation of the lever of gear shifting in situation "1", "2", "D" or "R". This tendency decreases in process of warming up of the engine and reduction of number of turns of its idling. Therefore at engine warming up before installation of the lever of gear shifting in one of aforementioned provisions it is recommended to press a pedal of a brake or to tighten the lever of the hand brake.

Situation "2" – automatic gear shifting with the 1st on the 2nd and back

The car begins movement on the 1st transfer and during movement there is an automatic switching only on the 2nd transfer. 3-яя transfer does not join. Situation "2" is recommended to be used during long-term descents from heights as in this situation probably enough intensive braking by the engine and, thus, brakes are preserved against excessive heating.


Prevention

The lever of gear shifting can be rearranged in situation "2" provided that speed of movement of the car does not exceed 100 km / h.


Situation "1" – the 1st transfer is constantly included

The car starts to move on the 1st transfer and there is no gear shifting on more highest. Situation "1" is recommended to be used during descents from abrupt heights as at this situation very intensive braking by the engine is possible. Moving of the lever of gear shifting to situation "1" during movement on the 3rd transfer causes transfer switching on the 2nd. Switching on the 1st transfer will occur only when speed of movement will fall to 20–40 km / h.

Prevention

The lever of gear shifting can be rearranged in situation "1" provided that speed of movement of the car does not exceed 100 km / h.
After automatic inclusion of the 1st transfer under no circumstances there will not come transfer switching on more highest.


During movement at the gear shifting lever established in situation "D" installation on the 1st transfer is possible at once provided that speed of movement of the car makes 30–50 km / h. It demands pressing of a pedal of an accelerator against the stop.

Use of a compulsory reduction of transfers (kick-down)

The pressing of a pedal of an accelerator against the stop does possible sharp acceleration during movement downhill or overtaking (except stipulated above cases of braking by the engine). At installation of the lever of gear shifting in situation "D" there is an automatic switching of transfer to the 2nd on the 1st. The described actions can be applied only in the corresponding range of speed of movement of the car.

Towage

The instructions concerning towage of the car, and also the car equipped with an automatic transmission look in subsection 1.4.
