Assign keys in settings:
(Any keys can be assigned!)
1 - Enable cruise control
2 - Increase in speed
3 - Speed reduction
4 - Resume

Cruise control is activated from a minimum speed of 30 km/h.
(If the speed is lower, it will not turn on!)
It can be turned on if the speed is above 50, 70, 85 km/h

1 - Turn on cruise control in the game.
An icon will appear on the dashboard of the truck:


2 - Now increase the speed, use the keys.
By default, the speed will increase by 5 km/h:


3 - Now you can set the speed you need:


4 - The speed reduction is switched by the keys and is also reduced by 5 km/h.

5 - Cruise control turns off when you slow down.
Resume speed activated by keys.
If the cruise control was disabled at a speed of 75 km/h, after its resumption it will remain the same.

If you want to increase or decrease the speed of adding, change these two parameters:
Example: UP 5 km/h - 10 km/h And so on.
Also the rate of decline: Bottom 5 km/h - 10 km/h And so on.

Cruise control reduces speed automatically.
If you are going down a mountain and your speed is 90 km/h, the cruise will keep it and the speed will increase by a few units. (For example 93 km/h)

Attention! Cruise control uses braking through the gearbox and it must have a retarder function.
