For example, if you are in DRIVE and are in 3rd (direct) gear, when you tap the shift lever one time to the left (-), the display will show 4 (ERS 4 is direct gear).

When in the DRIVE position in 5th gear, the first tap to the left (-) will downshift the transmission and display 5 (ERS 5 is the same as normal 4th gear). Another tap to the left (-) will shift the transmission down to ERS 4 (direct gear).

The transmission will shift to the range from which the vehicle can best be slowed down.
