Shifting Gear
Slip monitoring When the speeds of rotation of the front and rear
axles differ by more than the maximum permissib-
le value, integrated slip monitoring shifts up to the
next gear.
This increases driving stability on a slippery sur-
face.
Note
fSlip monitoring is also deactivated when
Porsche Stability Management (PSM) is swit-
ched off. Stopping fFor 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.
fFor a longer stop with the engine running,
select position N (neutral).
fDo not hold the car on a slope using the
accelerator. Use the brake pedal or the hand-
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Parking fGo easy on the accelerator.
fWhen parking or maneuvring in a small space,
control the speed by careful use of the footbra-
ke. 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 fPlease observe the chapter “TOWING” on Page
254.
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 for-
w a r d f a s t e n o u g h t o c a u s e r e a r w h e e l l o c k u p .
fDo not shift into R while the vehicle is moving forward.
A transmission fault is indicated by the following
symptoms:
–The 4th-gear display flashes.
– 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.
fAdapt your driving style to the changed hand-
ling.
fTo remedy the fault, please consult an authori-
zed Porsche dealer.

Maintenance, Car Care
177
Fuel Economy Fuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications.
Air cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated at correct pressure.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
fSwitch off the engine if stationary for longer
periods (traffic lights, jams, level crossings). fAny additional weight carried in the vehicle re-
duces fuel economy. Always keep cargo to a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to increa-
sed fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
The EPA estimated m.p.g. is to be used for
comparison purposes, actual mileage may
be different from the estimated m.p.g., de-
pending on your driving speed, weather con-
ditions and trip length. Your actual highway
mileage will probably be less than the esti-
mated m.p.g.
fPlease observe all local and national speed li-
mits.
Operating Your Porsche in other
Countries Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards. There-
fore, cars built for the U.S. and Canada differ from
vehicles sold in other countries.
If you plan to take your Porsche outside the conti-
nental limits of the United States or Canada, there
is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessive engine knock and se-
rious damage to both engine and catalytic con-
verters could result;
– service may be inadequate due to lack of pro-
per service facilities, tools or diagnostic equip-
ment;
– replacement parts may not be available or very
difficult to get.
Porsche cannot be responsible for the me-
chanical damage that could result because
of inadequate fuel, service or parts availabi-
lity.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about ship-
ping and forwarding requirements, as well as cur-
rent import and customs regulations.

Practical Tips, Emergency Service
Putting vehicle into operationAfter the battery is connected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest qualified
specialist workshop.
Have the fault remedied.
4. After the warnings disappear, stop the vehicle
in a suitable place.
5. Perform adaptation of the power windows:
Please observe the chapter “STORING END
POSITION OF THE WINDOWS” on Page 29.Ignition key/ignition lock
fDo not insert the ignition key into the ignition
lock if the vehicle battery is discharged.
The ignition key can no longer be removed.
The key cannot be removed until the vehicle elec-
trical system is supplied with power again.
fPlease observe the chapter “EMERGENCY UN-
LOCKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 228.
6. Please observe the chapter “JUMP LEAD
STARTING” on Page 236.
