Programs of work
The automatic transmission control system provides for various transmission programs. Depending on the actions of the driver or on the driving conditions of the car, either an economical program, i.e. aimed at saving fuel, or an active program, which can be called rather conditionally "sports".
The choice of the transmission program is carried out automatically depending on the nature of the driver's work with the accelerator pedal.
With the slow or normal nature of working with the accelerator pedal, due to the early inclusion of higher gears and the late transition to lower gears, it becomes possible to save fuel.
So-called "sports" the transmission program is selected when the accelerator pedal is operated sharply enough. At the same time, you should not press the accelerator pedal so vigorously so as not to unnecessarily cross the pressure threshold on the accelerator pedal, after which the forced advance shifting to a lower gear provided for in the gearbox control system occurs. When choosing "sports" mode, engine power reserves are fully utilized due to some delay in shifting to a higher gear.
Depending on the driving resistance, e.g. when towing a trailer or driving uphill, a program is automatically selected in order to provide more traction on the drive wheels by downshifting and thus avoid constant gear changes.
Sequential switching mode
Availability of sequential gear shifting mode (system "tiptronic") allows the driver to manually shift gears.
To switch to the manual switching program, it is necessary to move the selector from the position "D" to the right. The transition can be carried out both on a stationary car and while moving. Numbers appear on the display when shifting gears "5, 4, 3, 2, 1". The transmission currently on is shown.
Slight push of the selector forward (+) gears are sequentially turned up, and with a slight push back (-) - sequentially down.
When the car accelerates, 2nd, 3rd and 4th gears are automatically engaged shortly before the engine reaches the maximum permissible speed.
If the driver shifts from a gear to a lower gear, the transmission control unit will only engage this lower gear when there is no danger of engine over-revving.
Selector lock
Selector in positions "R" And "N" locked when the ignition is on. To remove the selector from these positions, press the brake pedal and press the button in the selector handle. Thanks to this, there is no situation when, due to negligence, one of the gears can be turned on and the car will start moving completely uncontrollably.
The design of the automatic transmission provides a delay device so that when moving from one position to another through the position "N" (for example, from "R" To "D") the selector was not blocked. Thanks to this, it is possible "rocking" stuck car. Only when the selector with the brake pedal released is more than one second in position "N", the selector is blocked.
At speeds above 5 km/h selector lock in position "N" turns off automatically.
