When the pedal of an accelerator is not pressed, the lever of a butterfly valve has to rest against the limiter for idling.

1) squeeze out an accelerator pedal to situation at which the butterfly valve is completely open
2) the end of a pedal has to be in 15–20 mm from the pedal limiter
3) squeeze out an accelerator pedal to the limiter
4) the lever of switching of the transmission has to concern the gear shifting limiter
5) the spring between arms of a rope has to be compressed

For cars with system a cruise control

1) adjust installation of connecting draft, having moved a spherical pin
2) and = 1.0–1.5 mm

For cars with the conditioner

The switch of the conditioner should not turn on at completely open butterfly valve but only when the pedal of an accelerator is squeezed out to the provision of switching of transfer.

At completely open butterfly valve, the distance between the switch and an arm of a rope has to be about 2.0 mm.
