Features of driving with automatic transmission

On cars of the Subaru brand the four-stage hydromechanical automatic transmission (AT) with the blocked hydrotransformer and an electronic and hydraulic control system is established. The control system of AT provides timely and smooth switching of all steps of the forward course. Blocking of the hydrotransformer improves fuel profitability of the car. On subjective feelings inclusion of a blocking friction clutch of the hydrotransformer similar to usual switching of a step of a transmission.

Transmission is equipped with the electronic control system providing the optimum gear shifting answering to any traffic conditions and a condition of a paving.

At the movement of the car uphill possibility of switching of transmission on higher transfer is automatically blocked if the control unit defines that the power unit will not provide further advance of the car with a former speed.

On abrupt descents the control unit can automatically switch transmission to lower transfer that increases efficiency of braking of the vehicle the engine and reduces intensity of wear of brake mechanisms. Attention: If automatic switching of transmission on a low gear at the movement downhill does not happen, the driver has to provide this switching independently!

Indicators of position of the AT selector


The lever of the selector of ranges of transmission can be in one of seven fixed provisions. At start of the engine the lever has to be only in the situation "P" or "N". If the stop of the car is made when AT is in one of movement ranges ("D", "3", "2", "1", "R", or "N"), it is necessary to release completely a pedal of gas and to squeeze out a pedal of a foot brake, or to cock the parking brake.


When transfer the lever of the selector in any of provisions of the movement surely squeeze out a pedal of a foot brake of the situation "N".

In structure of a combination of devices of the models equipped with automatic transmission the additional indicator lamps allowing the driver are built in it is easy to control position of the selector of ranges of AT.

Provisions of the lever of the AT selector


Situation "P". In this position of the lever of the selector of ranges the secondary shaft of transmission is mechanically blocked. Always transfer the lever of the selector of ranges to situation "P" at switching off or start of the engine. To bring the lever of the selector of ranges out of situation "P", it is necessary to squeeze out a brake pedal, previously having released a gas pedal. Reject the lever of the selector of ranges to the right and bring him out of situation "P".

 Having parked the car do not forget to cock the parking brake also.
In order to avoid breakage of AT transfer the lever to situation "P" only after a full stop of the car. Extraction of a key from the lock of ignition becomes possible only after transfer of the lever of the selector to situation "P".


Situation "R". (Neutral) make turning on of the lever in the situation "R" from the situation "N" only after a full stop of the car.

 Automatic transmission is equipped with the special safety device which does not allow to move the lever to the situation "R" if the speed of the car exceeds value of 10 ÷ 12 km/h incidentally. If the backing does not join after a full stop of the car, squeeze out a brake pedal and slowly move the lever of the selector of ranges at first to the situation "N", then to the situation "R".


Situation "N". Use the situation "N" (Neutral) at start of the decayed engine on the run of the car and at short stops of the car with the working engine. If you for any reason need to depart from the car, previously transfer the lever of the selector of ranges to situation "P" (Parking). At a lever conclusion squeeze out a pedal of a foot brake of the situation "N".

Situation "D". This situation is used in most cases at the movement in the conditions of not loaded city cycle and at the movement on highways. In this situation the control system of transmission uses the full range of forward transfers, in the corresponding situations the braking mode the engine automatically joins.

 At the movements uphill and under a bias the module of management of transmission (TCM) can make blocking of switching on the raised / low gear, minimizing thereby number of switchings and providing the maximum smoothness of the course of the car.


Situation "3". At transfer of the lever of the selector of ranges to the situation "3", the automatic transmission functions similar to a case of inclusion of range of "D". Difference consists that transition to the fourth transfer is excluded. Range "3" is recommended to be used at towage of the trailer in the hilly district or for braking implementation by the engine on descent of the considerable steepness. Inclusion of range "3" is useful also for an exception of excess cyclic switchings of automatic transmission between the third and fourth transfers. Similar cyclic switchings can be observed, for example, at the movement in a dense transport stream with frequent ottormazhivaniye and stops of the car.

For sharp dispersal of the car during the work of a transmission in the range of "D" or "3" squeeze out a gas pedal against the stop. Thus the transmission will automatically pass to adjacent lower transfer (kickdown mode).

 If the speed of the car is small, AT can switch at once to two steps down.


Situation "2". At inclusion of range "2" automatic transmission will constantly work at the second transfer. At a car stop the transmission does not pass to the first transfer. Continuous inclusion of the second transfer provides good traction dynamics of the car on rises and possibility of intensive braking with the engine on abrupt descents. Range "2" is recommended to be included at a start of motion on a slippery paving, and also at the movement on deep snow. It helps to prevent strong pro-slipping of driving wheels of the car.

At inclusion of range "2" on the run of the car inclusion of the second transfer to transmissions automatically is late and happens only after the speed of the car decreases to the safe level at which the frequency of rotation of a cranked shaft of the engine will not exceed the most admissible value.

Situation "1". At inclusion of range "1" automatic transmission will constantly work at the first transfer. If inclusion of range "1" is made at a speed more than 50 km/h, AT at first will switch to the second transfer. Inclusion of an intermediate step allows to exclude sharp and unexpected braking by the engine.

Switching of the modes of functioning of AT


The automatic transmissions used on the considered models of Subaru cars have three modes of functioning: Normal, POWER and HOLD. The translation of transmission from the normal mode in the POWER and HOLD modes is made by means of the push-button switch close to the AT selector lever.

HOLD mode


This mode is intended for the movement on roads with the lowered coefficient of coupling of a covering (snow, dirt). At activation of the HOLD mode the start-off of the car in the provision "D" of AT is made from the second transfer that considerably reduces probability of pro-slipping of wheels.

For transfer of transmission to the HOLD mode it is necessary to press back part of the push-button switch of the modes near the selector lever, - on an instrument guard the corresponding control lamp confirming serviceability of activation of the mode has to light up. Return the normal mode is made by repeated pressing of the same button.


POWER mode

 Activation of the POWER mode at the included HOLD mode is not represented possible.


The mode of the increased power of POWER is applied to sharp dispersal of the vehicle, and also at emergence of need for increase of efficiency of return of the engine.

Inclusion of the mode is made by pressing forward part of the switch of the modes, on an instrument guard the corresponding control lamp has to light up.


Application of the POWER mode during the movement leads to a delay of switching of transmission on overgears.

For shutdown of the mode once again press the same button.

The maximum admissible speeds of the movement of the car in various ranges of transfers

The maximum admissible speeds of the movement of the car at inclusion of various ranges of an automatic transmission are specified in Specifications. Excess of the maximum admissible speeds of switching leads to the engine overloads connected with excessive increase of turns. Besides, there is a powerful braking by the engine that is fraught with loss of control over management. Thus the electronic block of a control system of the engine starts limiting turns of a cranked shaft, reducing fuel supply that it is possible to feel on change of power setting. Operation of the engine returns to normal as soon as the arrow of a tachometer leaves a red zone of a scale.

In order to avoid breakage of the engine before transfer switching, make sure that the arrow of a tachometer does not come for value of the most admissible speed of the movement on this transfer and is not in a red zone of a scale.

Overtaking

During overtaking commission, when squeezing a pedal of gas to a floor there is an automatic switching of transmission on the next to chosen at the moment subordinate transfer (to the 4th on the 3rd, to the 3rd on the 2nd, to the 2nd on 1st - the kickdown mode), - need for any switchings of the lever of the selector thus is absent.

Short-term stop

At short-term stops, - for example on the traffic light, - it is possible to leave transmission on transfer, holding the car a foot brake.

At longer stops with the working engine it is necessary to transfer the selector lever to the situation "N", - before a start of motion do not forget to switch in the situation "D".

At a short-term stop on the bias going uphill it is not necessary to hold the car not movably by means of an accelerator, - use the foot or parking brake.

During braking avoid squeezing of a pedal of gas, - if the lever of the selector is not transferred to the situation "N" or "P", it can lead to unexpected acceleration.
