Operation, Safety
Parking Aids Parking assistantWhen the driver backs up, the parking assistant
system indicates the distance between the car
and a large obstacle behind it, by means of signal
tones.
Warning!
Risk of serious personal injury or death.
Parking assistant cannot detect small ob-
jects such as children and pets.
Despite use of the parking assistant system,
the driver is still responsible for taking due
care and assessing obstacles when backing
up.
f Make sure that no persons, especially small
children, animals or obstacles are within the maneuvering area.
The parking assistant syst em is activated auto-
matically when reverse gear is selected and the ig-
nition is on.
Note
Be aware that the parkin g assistant system is
not switched on if the car rolls backward without
reverse gear being engaged.
Ultrasound sensors Sensors
Four ultrasound sensors in the rear bumper meas-
ure the distance to the closest obstacle.
– Range middle sensors around 60 in./150 cm
– Range outer sensors around 24 in./60 cm
Obstacles cannot be detected in the “blind” sen-
sor area (e.g. near the ground). Note
The sensors must always be kept free of dirt, ice
and snow in order to ensure that they are fully
functional.
Caution!
To avoid damaging the sensors:
f Maintain sufficient distance when cleaning with steam-jet units.
Signal tones/function
When reverse gear is selected, the parking
assistant confirms that it is switched on by issuing
a short signal tone .
A detected obstacle is signalled by an intermit-
tent tone . The intervals decrease as the obstacle
is approached.
A continuous tone sounds when the distance
becomes less than one foot. This continuous tone
c a n s t o p i f t h e o b s t a c l e i s a p p ro a c h e d c l o s e r t h a n
one foot.
The radio volume should no t be so loud as to
drown out the signal tones.

Operation, Safety

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
- Control switch for door mirror adjustment Swivelling down mirror glass as a parking
aidf
Please see the chapter “SEAT MEMORY” on
Page 35.
– When reverse gear is engaged, the mirror glass on the passenger’s side swivels down
slightly to show the curb area. Preconditions
– Vehicle must be equipped with seat memory.
– Set the control switch
A to “passenger’s side”.
– Reverse gear must be engaged.
Returning mirror glass to its original position
f Drive forwards with a speed of over 4 mph
(6 km/h) or
f Set the control switch A to “driver’s side”.

Practical Tips, Emergency Service
219
Parking at the curb
Warning!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause hid-
den tire damage which is not noticeable until
later. Such damage can result in accidents at
high speeds causing serious personal injury
or death.
Depending on the force of impact, the edge
of the rim can also be damaged.
f If you are in doubt, have the wheel checked by
an expert, particularly if you suspect damage
on the inside.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Wheel alignment, wheel balancing As a precaution, have wheels with summer tires
balanced in the spring, and those with mud and
snow tires before winter.
Unbalanced wheels may affect car handling and
tire life.
Only the specified weight s may be used for wheel
balancing.
Self-adhesive weights must not come into contact
with cleaning agents, since they could drop off.
Uneven tread wear indicates wheel imbalance. In
this event, the vehicle should be checked at an au-
thorized Porsche dealer.
Warning!
If, during a trip, uneven running or vibrations
occur that could be caused by damage to
tires or the car, the speed must be reduced
immediately, but without braking sharply.
If you continue your trip without having the
cause of the fault reme died, you might lose
control of your vehicle which could cause se-
rious personal injury or death.
f Stop the vehicle and check the tires.
f If no cause for the fault can be found, drive
carefully to the nearest authorized Porsche dealer.
Wheels with Tire Pressure Monitoring
(TPM) sensorsBefore changing wheels, make sure that the
wheels are compatible with your vehicle's TPM.
f Check this with your authorized Porsche
dealer.Removing and storing tires fAfter changing, adjust tire pressure and torque
wheel bolts diagonally to 94 ftlb (130 Nm).
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with
their marking.
The perception that tire durability and perform-
ance are immune to the effects of storage and
age is unfounded.
Chemical additives, whic h make the rubber elas-
tic, lose their effectivene ss in the course of time
and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from
time to time.
