Depending on driving speed and engine speed,<br />
you can shift up or down at any time.<br />
Gear changes which would exceed the upper or<br />
lower engine speed limit are not executed by the<br />
controller.<br />
There is no automatic upshift at the upper engine<br />
speed limit in selector lever position M. Upshift<br />
suppression can be cancelled by kickdown operation.<br />
If, for example, the engine speed limit is<br />
reached during overtaking and the automatic<br />
upshift does not occur, the transmission in this<br />
case shifts up as a result of kickdown operation.<br />
f Select an appropriately low gear on upward<br />
and downward slopes.<br />
This will ensure optimum use of engine power<br />
and engine braking.<br />
In order to shift up automatically at the upper<br />
engine speed limit:<br />
f Depress the accelerator pedal beyond the fullthrottle<br />
point (kickdown).<br />
Failure of the selector lever display on the<br />
instrument cluster<br />
The warning “Transmission emergency run” is<br />
displayed in red on the on-board computer.<br />
– Effect:<br />
No selector lever position is displayed on the<br />
instrument cluster.<br />
Vehicle can be driven only until it comes to a<br />
stop.<br />
Remedy:<br />
It is not possible to continue driving. Immediately<br />
stop the vehicle in a suitable place. Have<br />
the vehicle towed to an authorized Porsche<br />
dealer.<br />

Stopping<br />
f For a brief stop (e.g. at a traffic light), leave the<br />
selector lever in drive position and hold the<br />
vehicle with the brake pedal.<br />
f Do not hold the car on a slope using the<br />
accelerator. Use the brake pedal or the<br />
handbrake instead.<br />
f Before leaving the vehicle, always apply the<br />
handbrake and move the selector lever to<br />
position P.<br />
Parking<br />
f Go easy on the accelerator!<br />
f When parking or manoeuvring in a small<br />
space, control the speed by careful use of the<br />
footbrake.<br />
Driving in winter<br />
In wintry road conditions it is advisable to take<br />
steep inclines in manual mode. This prevents gear<br />
changes occurring that could cause wheelspin.<br />
