Kickdown, function 

The driver's wish for the maximum vehicle acceleration is met by the kickdown function.

The kick-down function is activated from a pedal travel at the electronic accelerator > approx. 90 %.

When the electronic accelerator is pressed the driver will notice an increased backpressure at the kickdown point. For this purpose a kick-down simulator is integrated in the electronic accelerator.

The "Kick-down" signal is recorded by the accelerator pedal sensor, read in by the ME-SFI [ME] control unit and passed on to the drive train CAN to the ETC [EGS] control unit.

Based on this information the ETC [EGS] control unit actuates the control solenoid valve so that the upshifts and downshifts take place at increased engine speed in order to achieve maximum performance.
