Slip monitoring
When the speeds of rotation of the front and rear
axles differ by more than the maximum permissi-
ble value, integrated slip monitoring changes up to
the next gear.
This increases driving stability on a slippery sur-
face.
Note
Slip monitoring is also deactivated when Porsche
Stability Management (PSM) is switched off.
Stopping
f For a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the ve-
hicle with the brake pedal.
f For a longer stop with the engine running, se-
lect position N (neutral) and hold vehicle in po-
sition with the foot brake.
Select lever position D only when the foot
brake pedal is depressed.
f Do not hold the car on a slope using the
accelerator. Use the brake pedal or the hand-
brake instead.
f Before leaving the vehicle, always apply the
handbrake and move the selector lever to po-
sition P.

Shifting Gears
Parking
f Go easy on the accelerator!
f When parking or maneuvering in a small
space, control the speed by careful use of the
footbrake.
Driving in winter
In wintry 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
f Please observe the chapter "TOWING" on
Page 235.

A transmission fault is indicated by the following
symptoms:
– The 4th gear display on the instrument clus-
ter flashes.
– The warning "Tiptronic emergency run" ap-
pears on the on-board computer.
– The transmission no longer shifts.
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 for-
ward fast enough to cause rear wheel lockup.

forward.

fault:
1. Stop in a safe place.
2. Move selector lever to position P, switch the ig-
nition off and wait for 10 seconds.

thorized Porsche dealer.
