X Press the selector lever to the left towards D–.

The automatic transmission shifts down one gear and restricts the shift range to the relevant gear.

If the engine exceeds the maximum engine speed when shifting down, the automatic transmission protects against engine damage by not shifting down.

If the maximum engine speed for the shift range is reached and you continue to accelerate, the automatic transmission shifts up in order to prevent the engine from overrevving, even if the shift range is restricted.

Derestricting the shift range

Briefly press the selector lever to the right towards D+. The shift range is derestricted.

Clearing the shift range restriction

Press and hold the selector lever towards D+ until D is shown once more in the multifunction display. The automatic transmission shifts from the current shift range directly to D.

Selecting the ideal shift range

Press the selector lever to the left towards D– and hold it in position. The automatic transmission shifts to the gear which allows optimum acceleration and deceleration. To do this, the automatic transmission shifts down one or more gears.
