Limits of ultrasonic measurement
The parking assistant system cannot detect:
– sound-absorbing obstacles (e.g. powder snow),
– sound-reflecting obstacles (e.g. glass surfac- es, flat painted surfaces)
– and very thin obstacles.
– Other ultrasound sources (e.g. pneumatic brakes of other vehicles, jackhammers) can
interfere with detection of obstacles.
Fault indication
The parking assistant system indicates a fault in
two ways:
– After reverse gear has been selected, the short signal tone is followed by a continuous
tone of the same pitch:
This indicates that sensors are soiled or cov-
ered with ice.
– After reverse gear has been selected, the short signal tone is followed by a continuous
tone with a much lower pitch:
This indicates a general system fault.
Please have the fault remedied at an author-
ized Porsche dealer. A

Page 15.
f Please see the chapter “EMISSION CONTROL
SYSTEM” on Page 198.
Warning!
Serious injury or death may result if you are
involved in a collision without having fas-
tened the safety belts.
f Fasten safety belts before driving away. Before starting the engine fApply the footbrake.
f Manual transmission:
Fully depress the clutch pedal and put the gear-
shift lever into neutral.
The clutch pedal must be depressed fully
before the starter will engage.
f In vehicles with PDK transmission:
Move PDK selector lever to position P or N.
Temperature sensors on the engine automatically
provide the correct fuel/air mixture required for
starting.
Therefore, it is not necessary to depress the
accelerator pedal while starting a cold or a
warm engine.
Starting the enginef Turn ignition key to ignition lock position 2.
f As soon as the engine st arts, release the igni-
tion key.
The first operation of the starter is ended automat-
ically when the engine starts.
If the engine does not start, subsequent starter
operations will not be ended automatically.
If the engine fails to start after 10 or 15 seconds
of cranking:
f Wait about 10 seconds before engaging the
starter again.
f When starting the engine, be ready to drive
immediately.
Drive vehicle at moderate speeds and avoid
engine speeds above 4,200 rpm during the
first 5 minutes.
f Do not let the engine idle to warm up.
Danger!
Engine exhaust fumes have many compo-
nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
f Never start or let the engine run in an
enclosed, unventilated area.
It is not recommended to sit in your car for prolonged periods with the engine on and the
car not moving.
An unattended vehicle with a running engine
is potentially hazardous.
If warning lights shoul d come on to indicate
improper operation, they would go unno-
ticed.
f Never leave the engine idling unattended.
Danger of fire.
f Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or oth-
er flammable material.
f If your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put
out the fire.
Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot when the vehicle is running
and remains hot for some time after the vehicle is
turned off.
f To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe, and closely
supervise children around the vehicle when the
exhaust pipe could be hot.
A hot exhaust pipe can cause serious burns.

76
Operation, Safety
Stopping Engine fTurn key back to position 3.
f Do not stop engine immediately after hard or
extended driving.
Keep engine running at increased idle for
about two minutes to prevent excessive heat
build-up before turning off engine.
f To avoid discharging the battery, always re-
move the ignition key from the ignition lock.
f When leaving the car, always remove the igni-
tion key, apply the parking brake and engage
1st gear or reverse gear on vehicles with man-
ual transmission or move the selector lever to
position P on vehicles with PDK transmission.
f Engage the steering lock by moving the steer-
ing wheel to the left or right.
Turn the steering wheel to the locking position
before you switch off the engine so that you
don’t have to exert your self when locking or
unlocking the steering.
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
f Before working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently. Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot wh
en the vehicle is running
and remains hot for some time after the vehicle is
turned off.
f To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe, and closely

Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment bl ower is mounted in the
engine compartment.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.

Carry out work in these areas only with the en-
gine switched off.
Automatic garage door The ignition system in your Porsche may interfere
with your electronically operated garage door.
fTo check this, drive your Porsche close to the
garage door. Make sure not to interfere with
the operating range of the door.
f Run the engine at different speeds.
f If the garage door opens or closes without you
operating the garage door unit in your car,
contact the dealer who installed the automatic
garage door to have the frequency and/or
coding of the garage door signal changed or
modified.

Maintenance note
f Periodically clean the wiper blades with a win-
dow cleaner, especially after the vehicle has
been washed in a car wash. We recommend
Porsche window cleaner. If they are very dirty
(e.g. with insect remains), they can be cleaned
with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
If the vehicle is washed in an automatic car wash,
wax residues may be adhering to the windshield.
These wax residues can only be removed by using
a window cleaner concentrate.
