Start of motion and gear shifting

In go noschnom does not owe sources itself minor objects, capable consider to limit freedom of shift of pedals! At the appendix not of budget small carpets or Matta it is necessary to guarantee the sufficient movement of pedals.

Full load of the motor has to be given only after its preliminary warming up up to the normal working temperature which happens quickly enough during the movement.

At troganii from the place on slippery tourist providing you avoid for a long time proworatschiwanija some the leading gear wheels as it can lead to damage of the power plant.

Models with RKPP

The scheme of gear shifting is charged on the surface of a forehead of a hvataniye of the lever of gear shifting.

You make gear shifting during the movement according to technical characteristics of transmission, - you try not to allow the increased increase in changes. To the modern chapter the table of the bystry modes of gear shifting is provided in specifications.

Application of transfer of a backing has to be made only after a full break of the car, - upward it is necessary to sup the lever hvataniye is necessary before the appendix.

At the movement after slippery tourist providing it is not necessary to make it is necessary transmission brakes as it can lead to loss of connection of wheels with the road! They remember that brakes of the motor are always connected with strong increase in its changes, threateningly from serious internal damages of the power plant.

Models with AT

Gear shifting during the movement of the car is made automatically depending on position of the Selektors AT lever, position of the switch of programs, the provision of a pedal of a pedal of an accelerator and the current speed of the movement.

Switchings of automatic transmission automatically adapt to an individual manner of driving, due to correction of the moments of gear shifting. Process of adaptation goes continuously considering the current values of performance data of the power plant, characteristics of the movement, and also actions of the driver. Reacts to change of characteristics of the movement AT with the adapted program of gear shifting.

Prior to the movement you express a brake noschnogo pedal for removal of blocking of the Selektors AT lever, then you dismiss stojanotschnyj a brake (watch office a car stop) and you switch the Selektors lever to one of provisions of the movement. Expect full application of transfer, in particular, at the cold motor, then you dismiss noschnoj a brake and you express the accelerator pedal.

They remember that before final warming up of the motor gear shifting at slightly increased changes is made that guarantees the accelerated warming up of the catalytic reformer up to normal working temperature.

At the movement it is necessary to have it is necessary because of that the easy pressure upon the accelerator pedal guarantees earlier switching of transmission to an overgear while on the strong pressure of switching occur later.

Squeezing of the accelerator pedal to a floor leads the increased dynamic quality to automatic switching of AT to the reduced transfer (kickdown mode), the car guaranteeing. At otpuskanii of a pedal there is a return of transmission on higher transfer which answers characteristics of the current bystry mode.

You give to a break the Selektors lever in provision of the movement and by means of noschnogo or stojanotschnogo of a brake you assure the car against advance, on rise - from skatywanija back.

When maneuvering in the limited room you regulate the speed of the movement gradually of brake otpuskanijem noschnogo. Press an accelerator pedal pedal only slightly you do not play from it.

Towage of the adherent needs to be made it is necessary in the standard AT mode, - you transfer the switch of the modes to the left of the Selektors lever to situation "S".

Provisions of the Selektors AT lever

At the movement after slippery tourist providing it is not necessary to make it is necessary transmission brakes due to transfer of the Selektors lever to the modes of limited volumes "D2" and "D1" as it can lead to loss of connection of wheels with the road! They remember that brakes of the motor are always connected with strong increase in its changes, threateningly from serious internal damages of the power plant.

The Selektors lever of volumes of transmission can be in 7 fixed provisions. The start of the motor is possible only in provisions "P" or "N" of the lever. If the break is made if AT is in one of volumes of the movement "D4", "D3", "D2", "D1", "R", or "N", then it is necessary to dismiss completely the accelerator pedal and to express a foot brake for sure brakes of the car.

When switching AT you translate the lever along the judging fold. At extraction of a key from the ignition lock the Selektors lever is blocked in situation "R". In this case the conclusion of the lever from situation "R" is impossible even when squeezing a foot brake. For prevention of breakage of AT you transfer the lever to situation "R" only after a full break of the car.

Extraction of a key from the lock of ignition becomes only possible after transfer of the Selektors lever to the provision "R" and otpuskanija of a pedal noschnogo of a brake.

Situation "R"

Blocking of transmission which makes additional protection of saparkowannogo the car will be in this family way of the Selektors lever it is guaranteed. Always you transfer the Selektors lever to situation "R" at an exception or start of the motor. To remove the Selektors lever of volumes of situation "R", it is necessary to express a foot brake to dismiss meanwhile the accelerator pedal. Refuse the Selektors lever to the right and remove it provisions "R".

Situation "R"

Pictures of management of the Selektors lever of volumes when translating it from situation "R" in situation "R" (backing) are described above. You make application of the lever in situation "R" from situation "N" (Nejtral) only after a full break of the car. If the backing is not enlisted after a full break of the car, a pedal of noschnogo of a brake and slowly you transfer to a vyrazta the Selektors lever at first to situation "N", then to situation "R".

Situation "N"

Use situation "N" (Nejtral) at start of saglochschego of the motor on the movement and at short breaks of the car by means of the working motor. If you have to leave for some reason of the car, meanwhile you transfer the Selektors lever of volumes to situation "R". At the conclusion of the lever from situation "N" you express a brake noschnogo pedal.

Transfer of transmission to situation "N" during the movement is connected with risk of serious internal damages! Use this situation only at threat of sanossa of the car at the movement after slippery tourist providing.

Situation "D4"

In this situation the Selektors lever of volumes constantly has to be at the movement of the car in normal tourist conditions.

In volume of "D4" (movement) automatic gear shifting of a forward leg is guaranteed depending on the speed of the car and a step of Ausquetschens of the accelerator pedal.

Situation "D3"

If the Selektors lever of volumes is made in situation "D3", it functions automatic transmission gears is similar to a case of application of volume of "D4" ("movement").

Distinction consists that transition to the fourth transfer is excluded. Recommended "D3" to use volume at towage of the adherent in the hilly area or for execution of Bremsens from the motor on descent of the considerable steepness. Application of volume "D3" is useful also for an exception of excessive cyclic switchings of automatic transmission between the third and fourth transfers, - similar cyclic switchings of transmission gears, for example, at the movement can be observed in dense transport current at frequent delays and breaks.

For strong exile of the car in operating time of transmission in volume of "D4" or "D3" you express the accelerator pedal before blow. At the same time will automatically switch transmission gears to adjacent lowest transfer (kickdown mode).

If the speed of the car is small, switching can happen at 2 steps down at once.

Situation "D2"

At application of volume "D2" automatic transmission will constantly work at the second transfer.

At a break of the car does not pass transmission gears to the first transfer. Constant application of the second transfer guarantees well tjagowuju dynamics of the car on rises and a possibility of intensive Bremsens by means of the motor on abrupt descents.

The volume of "D2" can be used as an alternative of the winter mode (watt, - see below) at a start of motion on slippery tourist providing, and also at the movement on deep snow. It helps to prevent strongly probuksowku of the driving gear wheels cars.

"D2" recommended to use volume at the movement after abrupt passports, at towage of the adherent in the hilly area, and also for motor brakes on especially abrupt descents.

At application of volume "2" on the movement of the car activization of the second transfer automatically stops in transmission and only happens after car speed to sure level falls on which the frequency of Drehens of a bent shaft of the motor will not pass extreme value.

Situation "D1"

At application of volume "D1" automatic transmission will constantly work at the first transfer.

If application of volume "D1" at a speed the bigger number of 50 km for an hour is made, then transmission will switch to the second transfer at first. The appendix of an intermediate step allows to exclude strong and unexpected brakes from the motor.

The mode can be used at the movement with the adherent on especially abrupt descents and long passports.

Switching of the modes of functioning of AT

The switch of the modes of functioning of AT is to the left of the Selektors lever of transfers and is specified by letters of "W" and "S".

Standard S mode

The standard mode is activated in position "S" of the switch and is intended for the movement in normal tourist conditions.

Winter W mode

For transition to the winter mode of functioning of AT it is necessary to press it is necessary on the switch section "W".

In the winter troganije mode of the car of the place will be on the second transfer - except for which makes the movement with full loading or in position "D1" of the Selektors AT lever.

Switching of transmission will be on the strong pressure of a pedal of a pedal of an accelerator at lower speed of the movement smaller number of changes of the motor, than makes in situation "S".

The relation of transfer of transfer of a backing in situation "W" falls.

Necessary enterprise

About transition of transmission to the necessary enterprise of functioning confirm deterioration in dynamic characteristics and refusal of transmission on switchings. The probability of switching to the 2nd transfers or transfer of a backing is not excluded.

In a similar situation it is necessary to establish it is necessary to park the movement on the sure place, to transfer the Selektors lever to situation "R" and, to deafen the motor.

Oboschdaw is not less than 10 seconds, you start the motor again and you transfer the Selektors lever to situation "D" - it will be enlisted the 2nd transfer. Transfer of the lever to situation "R" leads to application of transfer of a backing.

The car needs to be banished it is necessary on the following service station Mercedes Benz for performing detailed diagnostics of AT and to execution of necessary repair of restoration at once.
