Automatic Transmission (AT)

5-staged Tiptronic

Introduction

The car is completed with 5-staged automatic transmission with electronic control. Switching on the raised and lowered steps is carried out automatically.

For the reasons of fuel consumption and environmental protection on some modifications transmission is arranged so that the maximum speed of the car is reached only in the situation "S".

The transmission is completed also with tiptronic system. This system gives to the driver, at desire, possibility of manual switching.

Maintenance instructions of automatic transmission

Switching on the raised and lowered steps of the forward course is carried out automatically.

Fragment of the central console: the selector lever with the blocking button

Start-off from a place

 PERFORMANCE ORDER

  1. Press and hold a brake pedal.
  2. Holding pressed the blocking button (on the selector lever), install the selector lever in the necessary situation, for example, the situation "D", and release the blocking button.
  3. Wait until automatic equipment executes inclusion, having created power communication of a transmission with driving wheels (at the time of inclusion the little push is notable).
  4. Release a pedal of a brake and press an accelerator pedal.

Short-term stops

 PERFORMANCE ORDER

  1. Hold the car a brake pedal, for example, at traffic lights.
  2. Thus do not press an accelerator pedal.

Parking

 PERFORMANCE ORDER

  1. Press and hold a brake pedal.
  2. Completely tighten the emergency brake.
  3. Holding pressed the blocking button, install the selector lever in the situation "P" and release the blocking button.

The engine can be started only when finding the lever of the selector in situation "P" or "N", see Features of operation and auxiliary systems.

At the parking out of the blue it is enough to install the selector lever in situation "P". At a slope of the road tighten at first against the stop the emergency brake and only then transfer the selector lever to situation "P". Thanks to it load of the mechanism of blocking decreases and moving of the lever of the selector from situation "P" is facilitated.

Provisions of the lever of the selector

The description of all provisions of the lever of the selector is provided in this section.

Display: provisions of the lever of the selector

The allocated indication of actual position of the lever of the selector is brought to the display of a control panel.

Р - parking blocking

In this situation driving wheels are blocked mechanically. This situation should be included only on the motionless car.

For installation of the lever of the selector in situation "P" and its conclusion from this situation press the blocking button (on the selector lever) and, at the same time, a brake pedal.

R - transfer of a backing

At installation of the lever of the selector this situation joins transfer of a backing.

Include transfer of a backing only at the motionless car and during the operation of the engine idling.

For installation of the lever of the selector in situation "K" press the button of blocking and at the same time a brake pedal. At the included ignition and finding of the lever of the selector in the situation "R" backing headlights burn.

N - neutral situation (provision of idling)

This situation is the provision of idling.

D - a basic position at advance

In this situation switching on the raised and lowered steps of the forward course is carried out automatically, depending on loading of the engine, speed and the dynamic program of switching (DPS).

From the situation "R" in the situation "D" at a speed less than 5 km/h or the motionless car it is necessary for the translation of the lever of the selector press a brake pedal.

Under certain circumstances, (for example, at the movement in mountains or with the trailer) it is more preferable to switch temporarily to the manual program of switching see below.

S - sports situation

Install the selector lever in the situation "S" at the movement in the sports mode. Later switching on the raised steps allows to use engine capacity reserves completely.

For the translation of the lever of the selector from the situation "N" in the situation "S" at a speed less than 5 km/h or the motionless car press a brake pedal

At the inadvertent transfer during the movement of the lever of the selector to the situation "N" before returning to the D or S mode, dump gas and wait for falling of turns to the idling mode.

For the reasons of fuel consumption and environmental protection on some modifications transmission is arranged so that the maximum speed of the car is reached only in the situation "S"

Blocking of the lever of the selector

Blocking of the lever of the selector prevents involuntary inclusion of range of the movement and by that the spontaneous movement of the car from a place.

Cancellation of blocking is carried out as follows:

  1. Include ignition.
  2. Press a pedal of a brake and hold at the same time pressed the blocking button.

Automatic blocking of the lever of the selector

At the included ignition the lever of the selector is blocked in the situation "P" and "N". For moving it from these provisions press a brake pedal. As a reminder to the driver when finding the lever of the selector in provisions "P" and "N" on the display there is the following indication:

Beim Einlegen einer Fahrstufe im Stand Fussbremse betatigen (at a choice of the mode of the movement of the motionless car press a brake pedal).

Besides, on the coulisse of the lever of the selector the symbol of automatic blocking of the lever of the selector lights up.

The lever of the selector is blocked only on the motionless car, and also at a speed up to 5 km/h. At a speed approximately from 5 km/h and there is an automatic cancellation of blocking of the lever of the selector which is in the situation "N" above.

At fast (without pauses) the translation of the lever of the selector through the situation "N" (for example, from the situation "R" in the situation "D") the lever of the selector is not blocked. It gives, for example, the chance of the movement "vraskachku" of the got stuck car. If the selector lever at the released pedal of a brake is more than 1 second in the situation "N", it is blocked.

Blocking button

The button of blocking of the lever of the selector interferes with involuntary transfer of the lever of the selector to some provisions. When pressing this button the lever of the selector is deblocked.

Blocking of a key in the ignition lock

After ignition switching off the key can be taken from the lock only when finding the lever of the selector in situation "P" (parking blocking).

After extraction of a key from the lock the lever is blocked in situation "P".

Kick-down device

The Kick-down device allows to realize the maximum acceleration.

By sharp pressing of a pedal of an accelerator with transition of a point of resistance automatic equipment switches, depending on turns and speed, on a low gear. Switching on the following overgear happens right after achievement of the maximum turns of the engine corresponding to this transfer.

Dynamic program of switching (DPS)

Management of automatic transmission is carried out by electronics.

Management of automatic transmission is carried out by electronics. Switching on the raised and low gears is carried out according to the programs of the movement which are stored in memory.

At a reserved manner of driving automatic equipment chooses the economic program of switching.

At a temperamental manner of driving with sharp dispersals and frequent differences o
