Adaptive shifting programs: Notes
Adaptive shifting programs are selected automatically depending on the engine load. The function is available in the normal program.
Shifting occurs at higher engine RPMs 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 grades with a trailer, and also to avoid overheating the transmission fluid.
Adaptive shifting programs are selected automatically if the transmission fluid becomes overheated in order to spare the transmission from serious damage and also 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 active 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 disengaged if:
- SPORT or WINTER program is selected. On cars with buses, only if the WINTER program is selected.
- the ignition switch is turned to the ON or OFF position
- The load decreases so much that an adaptive shifting pattern is no longer required.
- CHECK GEARBOX lamp lights up.
