2.5.9. Use of an all-wheel drive mode

Disconnect modes 4Н and 4LO at movement on roads with a dry firm covering.

If at movement on a dry firm covering the control lamp of an all-wheel drive mode 4WD lights up (see the Head of System of cooling and heating), in modes AUTO and 4Н it is necessary to translate the switch of an all-wheel drive mode 4WD in position 2WD, in a mode 4LO it is necessary to stop movement to switch АТ in position N and only after that to translate the switch 4WD in position 2WD, — at the first possibility drive away the car on a car repair shop for carrying out of corresponding diagnostics and performance of necessary regenerative repair.

Polnorezhimnye systems 4WD allow to choose one of four possible positions of a distributing box (AUTO, 2WD, 4Н and 4LO). The mode choice is defined by road conditions.

The order of change of modes is resulted in the table.

For mode inclusion 4LO it is necessary to press the switch handle. For inclusion and mode deenergizing 4LO the car should be stopped, and transmission is translated in position N.

For movement on paved roads or roads with a dry covering (an economic mode), and also at testing carrying out in frameworks THAT with application of a static dynamometer

All wheels

 

For movement on stones, sand and snow-covered roads

Neutral position

Can мигать*

At neutral position there is a switching-off of parking mode АТ that is interfaced to danger скатывания the car, — do not leave a distributing box in neutral position

1. Stop movement.
2. Translate selector AT lever in position "N".
3. Press the switch handle 4WD and translate it in position 4LO or 4Н.
Without a preliminary stop of the car and transmission switching in position "N" switch transfer in one of the stipulated positions is not represented возможным. **

All wheels

 

It is activated

If necessary to develop the maximum traction effort (for example at movement on an abrupt slope, the stony, sandy or strongly polluted district)


* If after performance of the table of procedure stipulated in the corresponding column the control lamp 4LO continues to blink, follows will continue movement with small speed and to try, whenever possible not to make sharp maneuvers until the lamp will not pass a mode of a continuous luminescence, or will not go out.
At movement in a mode 4LO try not to make sharp accelerations and turns in order to avoid excessive deterioration of gear wheels and drive damage.


** Track serviceability of operation of a control lamp 4LO while translating the switch 4WD in corresponding position.


Safety measures

  • At a parking of the car do not forget to cock a lay brake before deenergizing of the engine and watch that the control lamp 4WD has been activated, and lamp АТР is extinguished, otherwise the car can spontaneously start moving even in spite of the fact that the selector lever is translated in position Р!
  • Never make switchings between modes 4LO and 4Н during movement!
  • Position 4Н provides the raised traction effort and the best coupling with road, — try to move with speeds no more than 80 km/h!
  • Position 4LO provides the maximum traction effort and the best coupling with road, — try to move with speeds no more than 50 km/h!
  • The switch 4WD can be translated in positions 2WD, AUTO and 4Н at rectilinear movement, — do not try to make switching at movement by a backing or at fulfilment of turns, it is equal as at abrupt descents / liftings with proslipping of back wheels!
  • Movement in modes 4Н and 4LO on a dry firm covering is interfaced to appreciable increase of a noise background and is fraught with premature deterioration of protectors, — pass in a mode 2WD or AUTO!
  • Use of differential of the limited sliding (LSD) provides to the car the raised passableness in cross-country conditions at the expense of increase in characteristics of coupling with soil, however is interfaced to increase of level of vibrations and squeal of tyres at movement on paved roads!
  • At low temperatures there can be problems with switching of a distributing box between positions 4Н and 4LO. The control lamp of position 4LO can start to blink even the included all-wheel drive mode. Short run with small speed and without fulfilment of maneuvers allows to carry out switching between positions 4Н and 4LO!


Use of modes 4WD at movement in cross-country conditions

By means of the switch 4WD choose corresponding of all-wheel drive modes of a distributing box (AUTO, 4Н or 4LO).

Move slowly, соразмеряя speed with road conditions.

For liberation of the got stuck car enclose under wheels flat stones or wooden beams and switch a distributing box in a mode 4Н or 4LO and try to shake the car, alternately including that a lobby, a reverse gear. In case of need use wheel chains. Try not to suppose проворачивания wheels with high speed as it result е to stronger заглублению them in a liquid dirt, sand or snow.


Rules of application of the switch of modes of a distributing box

The site of the switch of modes of a distributing box — see an illustration the Scheme of an arrangement of controls the panel of devices of the car.

The choice of a mode from four possible (2WD, AUTO, 4Н and 4LO) is made according to road conditions.

In position AUTO change of distribution of a twisting moment between forward and back driving wheels is made automatically depending on change of road conditions, the following parity thus takes place: 0:100 (2WD)> 50:50 (4WD), allowing in an essential measure to raise stability of movement.

Switch use in mode AUTO, 4Н or 4LO during turn fulfilment, at an acceleration / braking by the engine or ignition deenergizing can cause jerks that is norm and should not cause anxiety.

Transfer of the lever of selector AT in position N or Р at a stop of the car after turn fulfilment can lead to the easy twitching of the car connected with deenergizing of coupling of a distributing box.


Safety measures

  • Do not make switching of a distributing box between modes 2WD, AUTO and 4Н during fulfilment of turns, at movement by a backing or on an inclined surface!
  • In order to avoid damage of internal components before box transfer in a mode 4Н from a mode 2WD or AUTO check, that speed of movement of the car did not exceed 80 km/h!
  • At all do not make box switching between modes 4LO and 4Н during movement!
  • Remember that at the cold engine its single turns are a little raised, — observe extra care at movement on a slippery or loose covering with included mode AUTO!


The light indicator of modes of a distributing box

The light indicator of modes of a distributing box is built in a tachometre dial (the Scheme of an arrangement of elements of a combination of devices see an illustration) and should quickly (for 1 second) to work at ignition inclusion, confirming with that serviceability of functioning of corresponding system.

At the started engine the indicator serves for the display of a mode of a distributing box chosen by means of the lever of the selector or the switch 4WD (see above).

Switching of modes can cause an indicator blinking, however on termination of a choice it should pass in a mode of a constant luminescence. If the indicator continues to blink after switching end, it is necessary to be passed a little forward with acceleration or деселерацией, or to be passed by a backing, then to repeat procedure of switching of a mode of a distributing box.

Activation of a control lamp 4WD (see more low) should be accompanied by switching-off of the light indicator of modes of a distributing box.


Safety measures

  • In cold weather the choice of mode AUTO can be accompanied by the indication 4Н the light indicator (see the table of switchings of a distributing box resulted above). Thus twisting moment distribution between forward and back driving wheels of the car will correspond to a mode 4Н, is interfaced to risk of occurrence of a phenomenon of sharp braking and difficulties at fulfilment of turns! After short time the indicator (and a distributing box) should be switched in mode AUTO.
  • If in cold weather the indicator shows position 2WD at chosen mode AUTO or 4Н, the probability of spontaneous switching of a box in a mode 2WD is not excluded. If after a while the situation is not corrected also the indicator will not start to give out the correct indication, the car should be driven away on a car repair shop.


Control lamp of an all-wheel drive mode


The scheme of functioning of a control lamp of an all-wheel drive mode

The control lamp also is built in a tachometre (the Scheme of an arrangement of elements of a combination of devices see an illustration), quickly works at ignition inclusion, confirming with that serviceability of the functioning, and should go out right after realisation of start of the engine, — refusal of a lamp of deenergizing or its transition in a flashing mode testifies to infringement of serviceability of functioning of system 4WD.

Operation of a control lamp in neutral position of a distributing box, means necessity of transfer of the switch 4WD in position 4Н or 4LO.

Activation of a control lamp should be accompanied by switching-off of the light indicator 4WD (see above).

The overheat трансмиссионного oils in a distributing box leads to operation of a control lamp in a flashing mode with frequency of an order two gleams in a second (the Scheme of functioning of a control lamp of an all-wheel drive mode see an illustration), — the car should be parked immediately in a safe place and to continue movement only after a lamp will go out.

The reason slow (an order of one gleam in two seconds) blinkings of a lamp during movement the considerable difference in diameters of forward and back wheels (the Scheme of functioning of a control lamp of an all-wheel drive mode see an illustration) can be, — be switched in a mode 2WD and try to move not too quickly, at the first possibility change wheels.


Safety measures

  • At operation of a control lamp in a continuous mode during movement or in редкопроблесковом a mode after a stop the car should be driven away at the first possibility on a car repair shop!
  • Try to avoid switchings of a distributing box between positions 4Н and 4LO at a burning control lamp 4WD!
  • Activation of a control lamp can mean that the car moves in a mode 2WD in spite of the fact that the switch 4WD is translated in position AUTO or 4Н, — observe extra care at driving. At refusal of some components of system inclusion of an all-wheel drive mode can be blocked!
  • In operation of a control lamp can result use of modes 4Н and 4LO at movement on a dry firm road covering, — if mode AUTO or 4Н is activated, translate the switch 4WD in position 2WD; at the included mode 4LO movement should be stopped, transmission to translate in position N and only then to be switched in a mode 2WD. If performance of the ordered actions does not lead to switching-off of a control lamp, the car should be driven away on a car repair shop!
  • Car operation at blinking in частопроблесковом a mode to a control lamp 4WD it is fraught with failure of a distributing box!
