Automatic gear box control

Start of the vehicle motion
1. Start the engine. Automatic engine mode is en-
gaged. The system automatically chooses the gear for start-
ing from standstill.
2. Shift the rotary switch from «N» position to «D»
position (see Fig. Gear shifter).
3. Depress the fuel feed pedal and release the park-
ing brake. With fuel feed pedal depressed the clutch is au-
tomatically engaged, and the vehicle starts moving.
For starting from standstill from neutral position
of the gearbox the 1st-4th gear engagement is possible.
All upshifts and downshifts are carried out auto-
matically depending on the vehicle load.
When moving in automatic mode the other gear
can be chosen by pressing on the gear shifter handle up-
wards (III) or downwards (IV). Automatic mode in such a
case is not disengaged.
Upshifting can be carried out by changing of fuel
feed pedal position:
- light pedal depression causes the earlier upshifting;
- strong pedal depression causes the later upshifting.
To drive-up depress the fuel feed pedal. When the
maximum, for these conditions, engine crankshaft speed
in the gear engaged is achieved, electronic control system
automatically upshifts the next gear.
