Gearshift Program
Normal program
When driving with normal accelerator pedal application the Transmission Control Module uses a preset gearshift program, optimized to shift for economical driving. This gearshift program is designed for "normal" driving which combined provides early upshifting and lock-up. The gearshift program automatically adapts to different driving cases such as driving uphill with a trailer or driving at high altitude. In addition, transmission oil pressure is adapted to provide gentle engagement of the gears.
Winter program
Winter mode is selected with the button on the top panel of the gear selector assembly. Winter mode makes it possible to start in a high gear to prevent wheel spin on a slippery surface. The program is also suitable for other difficult situations where the driver wishes to limit gear selection. When the gear position is the vehicle starts in 3rd gear. Automatic shifting takes place between 3rd, 4th, 5th and 6th gear.
When the winter program is selected a W is lit in the combined instrument panel.
If kickdown is activated in winter mode then the transmission uses all gears for optimum performance.
Sport mode - Only S60R and V70R
On R-models, the function is replaced by. Sport mode is activated with button on the top panel of the gear selector assembly. The program adapts shift points to provide the best possible performance. Downshifting occurs quicker at lower throttle application.
The function can also be activated automatically if the button on the dashboard is pressed.
