Front luggage compartment Trunk Entrapment Your vehicle is equipped with an internal front trunk
release mechanism.
A person trapped in the front luggage compart-
ment can release the lid from the inside using un-
locking handle A.
The handle A is fluorescent and glows in the dark.Note
When loading the luggage compartment, make
sure that items of luggage or other objects cannot
become caught on handle A.
This could cause the luggage compartment to
open unintentionally.
A warning message in the on-board computer
lights up when unlocking handle A is operated.
fStop the vehicle immediately when the warning
message lights up.
fCheck the luggage compartment.
fClose the lid.
Function with vehicle stationary
If the luggage compartment lid is unlocked with
unlocking handle A, the lid can be opened from the
inside immediately.
Function with vehicle in motion
If the luggage compartment lid is unlocked with
unlocking handle A when a speed of 2
mph
(3 km/h
) is exceeded, the warning message in
the on-board computer
lights up.
At the same time, the lid is unlocked and the latch
striker pops into the catch-hook position.
Danger!
Risk of accident.
If the warning message in the on-board com-
puter lights up when the vehicle is in motion,
the lid may impact in front of the windshield
and can tear off.
You can lose control of the vehicle, and
serious personal injury or death may result.
fStop the vehicle immediately when the warning
message lights up.
fCheck the luggage compartment.
fClose the lid.
Note
The front lid cannot be opened from the inside if
the battery is disconnected or empty.
Safety reasons therefore require that you un-
screw the latch striker of the front lid lock if
you plan to put the vehicle out of operation
for an extended period.
Please consult your authorized Porsche dealer.
They will advise you about the necessary measu-
res.

Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle resul-
ting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do safely.
fCarry out any complicated operating or setting procedures only with the vehicle stationary.The reception conditions for the radio module inte-
grated in the PCM change continuously as you
drive. Interference from buildings, terrain and the
weather is unavoidable.
FM stereo reception is particularly susceptible to
varying reception conditions.
Accessories which have not been tested and
approved by Porsche may impair radio function
and reception.
NavigationWhen put into operation for the first time, a
distance of approx. 31 miles (50 km) must be dri-
ven in order for the navigation system to complete
the process of fine calibration.
The same applies when the tires are changed (e.g.
summer/snow tires) or new tires fitted.
Full location accuracy is not yet achieved during
the fine-calibration process.
If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes after
being switched on before it determines the current
location.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system becomes operational again.

Shifting Gear
Indicator for selector lever position and
engaged gear When the engine is running, the selector lever po-
sition and engaged gear are indicated. If the selector lever is between two positions:
– The corresponding selector lever position in
the instrument cluster flashes and
– the warning “Selector lever not engaged” ap-
pears in the on-board computer.
fEngage the selector lever correctly.
– The selector lever position is displayed imme-
diately after the correct position has been de-
tected.
– The current gear is shown after a brief detec-
tion period.If there is a fault in the transmission:
– The 4th-gear and the selector lever position se-
lected displays flash in alternation.
– The warning “Tiptronic emergency run” ap-
pears on the on-board computer.
Please observe the chapter “EMERGENCY
PROGRAM” on Page 170.
– Have the fault remedied at an authorized
Porsche dealer.

Shifting Gear 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.
fHave the fault remedied.
Consult an authorized Porsche dealer.
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 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 fPlease observe the chapter “TOWING” on Page
260.
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 han-
dling.
fTo remedy the fault, please consult an author-
ized Porsche dealer.

Maintenance, Car Care
Engine Oil Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the lubri-
cant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil lev-
el at all, even after 600 miles (1000 km) or more.
This is because the oil is gradually becoming dilut-
ed with fuel or moisture, making it appear that the
oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater. If the vehicle is driven at a high rate of speed, cli-
matic conditions are warm, and the load is high,
the oil should be checked more frequently, as driv-
ing conditions will determine the rate of oil con-
sumption.
– The engine in your vehicle depends on oil to lu-
bricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked with every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occurring when lit, if
engine rpm is above idle speed.
Engine Oil Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
fRegularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please observe the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 110.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.2 liters.
Each segment of the display corresponds to
approx. 0.4 liter.
