Upshift prompt for fuel-economy-optimised
driving
The consumption-oriented upshift indicator

in
the tachometer at the right beside the digital
speed display helps you to develop a fuel-saving
driving style.
The upshift indicator lights up - prompting you to
shift up to the next-higher gear - depending on the
selected gear, engine speed and accelerator
pedal position.
The upshift indicator is only active when “Sport” or
“Sport Plus” mode is switched off.

Shifting down –
f
Pull the PDK selector lever or shift button on
the steering wheel back.
You can shift up or down by the corresponding
number of gears by quickly pressing or pulling the
shift buttons or selector lever several times in
succession.
The transmission can be shifted up or down by
several gears in succession by continuously
operating the selector lever or shift buttons.
You can shift up or down at any time depending
on driving speed and engine speed.
Gear changes that would exceed the upper or
lower engine-speed limit are not executed by the
control unit.
There is no automatic upshift at the upper engine-
speed limit in selector-lever position
M
. Upshift
suppression can be cancelled by kickdown
operation. If, for example, the engine-speed limit
is reached during overtaking and an automatic
upshift does not occur, the transmission shifts up
in this case as a result of kickdown operation.

speed limit:
