Mileage up to 2000 km:
Move by changing the engine speed and vehicle speed.
Do not allow the engine speed to exceed 4000 rpm.
Attention: When moving in 5th gear, do not develop speed more than ⅔ of the maximum possible.
Avoid driving at wide open throttle and therefore do not fully depress the accelerator pedal (avoid mode "Kick-down").
Mileage over 2000 km:
At this stage, you can gradually (not right away!) increase the speed and engine speed to maximum.
The break-in rules apply not only to the engine, but also to the rear axle gearbox.
If during subsequent operation the engine or rear axle gearbox is replaced, then you should start using the car, observing the rules for running in.
During the break-in period, the parts have not yet been run in, so there may be some difficulty when shifting gears, turning the steering wheel, etc. After a while, these phenomena should disappear.
