If manual mode fails, the control electronics switch
to automatic mode. In this event, the instrument
cluster will display selector lever position D.
To remedy the fault, please consult an author-
ized Porsche dealer.
PSM switched off and/or Sport mode switched
on
Please observe the chapter "SWITCHING OFF
PSM" on page 72.
Please observe the chapter "SPORT MODE" on
page 70.
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
The restriction can be cancelled for one gear
change by depressing the accelerator to kickdown.
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 by
accelerating to kickdown.
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 instrument
cluster will display selector lever position D.
Have the fault remedied. Consult an author-
ized Porsche dealer.
Stopping
For a brief stop, e.g. at a traffic light, leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
For a longer stop with the engine running,
select position N (neutral).
Do not hold the car on a slope using the
accelerator. Use the brake pedal or the
handbrake instead.
Before leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Parking
Go easy on the accelerator.
When parking or maneuvering in a small
space, control the speed by careful use of
the footbrake.
Driving in winter
In wintery road conditions it is advisable to take
steep inclines in manual mode. This prevents the
occurrence of gear changes that could cause
wheelspin.
Tow-starting, towing
Please observe the chapter "TOWING" on page
292.
Emergency program
Warning!
Reverse gear lock monitoring is disabled in
the emergency running program. Damage
to the vehicle may result as well as loss of
control, if the vehicle is moving forward fast
enough to cause rear wheel lockup.
Do not shift into R while the vehicle is moving
forward.
A transmission fault is indicated by the following
symptoms:
– The display for 4th-gear and the engaged
selector lever position flash on and off
alternately.
– The warning "Tiptronic emergency run"
appears in the on-board computer.
– The transmission no longer shifts. Regardless
of selector lever position, 4th is the only
forward gear still available.
Adapt your driving style to the changed
handling.
To remedy the fault, please consult an author-
ized Porsche dealer.
