Porsche 911 Carrera Manual page 145

Two rocker switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward speeds.
Shifting up
f Press upper part (+) of a rocker switch.
Shifting down
f Press lower part (–) of a rocker switch.
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 will not be executed by
the controller.
You can change down two gears by quickly press-
ing the rocker switches twice.
If the engine-speed limit is reached, an automatic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
Select an appropriately low gear on upward and
downward slopes.
This will ensure optimum use of engine power and
engine braking.
PSM switched off and/or Sport mode
switched on
f Please observe the chapter "PORSCHE STABI-
LITY MANAGEMENT (PSM)" on Page 63.
f Please observe the chapter "SPORT MODE" on
Page 62.
If the PSM is switched off and/or Sport mode is
switched on, an automatic upshift does not occur
when the engine speed limit is reached.
Cancelling upshift suppression
This restriction can be cancelled for one gear
change by depressing the accelerator to kick-
down. If, for example, the engine speed limit is
reached during overtaking and the automatic up-
shift does not occur, the transmission in this case
shifts up by accelerating to kickdown.
f Depress the accelerator pedal beyond the full-
throttle point (kickdown).
Manual mode failure
If manual mode fails, the control electronics
switch to automatic mode. In this event, the instru-
ment cluster will display selector lever position D.
f Have the fault remedied at an authorized
Porsche dealer.
