2010 PORSCHE 911 CARRERA Owners Manual

Shifting Gears
175
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or
lower engine speed limit are not executed by the
controller.
There is no automatic upshift at the upper engine
speed limit in selector lever position M. Upshift
suppression can be cancelled by kickdown opera-
tion. If, for example, the engine speed limit is
reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up as a result of kickdown operation.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
In order to shift up automatically at the upper
engine speed limit:
fDepress the accelerator pedal beyond the full-
throttle point (kickdown).Failure of the selector lever display on the
instrument cluster
