Adaptive shifting programs: Notes
Adaptive shifting programs are selected automatically depending on the engine load. The function is available in the normal and sport programs.
The shifts occur at higher engine RPM and the gear is engaged for longer if the control module senses that the load does not decrease. These shifting programs are in place to avoid unnecessary up and downshifting, for example, when driving on long uphill stretches with a trailer as well as to prevent overheating of the transmission fluid.
Adaptive shifting programs are selected automatically if the transmission fluid becomes overheated, in order to prevent serious transmission damage as well as to decrease the transmission fluid temperature. Activation occurs when the temperature exceeds 150 °C.
The adaptive shifting programs are not activated at speeds above 150 km/h. If an adaptive shifting program is activated when the speed increases to above 150 km/h, the program is maintained until the control module senses that a more suitable shifting pattern can be activated.
Adaptive shifting programs are deactivated if:
- The winter program is selected.
- The ignition key is turned to the ON or OFF positions.
- The load decreases so much that an adaptive shifting pattern no longer is needed.
- CHECK GEARBOX lamp lights up.
