Maintenance and Car Care Always observe the following points:
– Use only engine oils approved by Porsche.
This is a precondition for optimum and
problem-free operation of your vehicle.
– The engine oil is changed regularly during
servicing.
It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the Maintenance Schedule.
We recommend that you have the engine oil
changed at your authorized Porsche dealer.
– Oils approved by Porsche can be mixed with
each other.
– Porsche engines are designed so that no oil
additives may be used.
– A label located in the engine compartment
provides you with details of the most suitable
oil for your engine.
Your authorized Porsche dealer will be pleased to
advise you.

Warning!
Fire hazard if engine oil comes into contact
with hot engine parts.
Risk of damage if engine oil comes into con-
tact with the drive belt.
fExercise great care when adding engine oil.
Engine oil filling point on Cayenne1. Unscrew cap of the oil filler opening.
2. Add at most half a liter of engine oil at a time.
3. Measure oil level again after a few minutes.
Never exceed the MAX mark on the oil
dipstick.
4. Push oil dipstick in as far as the stop.
5. Carefully close cap of the oil filler opening.

Maintenance and Car Care

Fuel RecommendationsYour Porsche is equipped with catalytic conver-
ters and must use UNLEADED FUEL ONLY.
Your engine is designed to provide optimum
performance and fuel economy using unleaded
premium fuel with an octane rating of 98 RON
(93 CLC or AKI). Porsche therefore recom-
mends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least 95 RON
(90 CLC or AKI), since the engine's “Electronic
Octane™ knock control” will adapt the ignition
timing, if necessary.
It is important to observe the regular service inter-
vals, and particularly the oil change intervals, spe-
cified in your Maintenance Schedule.
The use of UNLEADED FUEL ONLY is critically
important to the life of the catalytic
converters. Deposits from leaded fuels will
ruin the converters and make it ineffective
as an emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps have smaller
nozzles. This will prevent accidental pumping of
leaded fuel into cars with catalytic converters.Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we
recommend you do not take your car to areas or
countries where unleaded fuel may not be
available.
Octane ratingsOctane rating indicates a fuel's ability to resist
detonation. Therefore, buying the correct octane
gas is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S. Cost of Living Council oc-
tane rating) or AKI (antiknock index) octane rating
usually displayed on U.S. fuel pumps is calculated
as research octane number plus motor octane
number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON corresponds 90 CLC or
“AKI”
fDo not use fuel additives without Porsche
approval.
Fuels containing ethanolfDo not use any fuels containing more than 10
percent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems
occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially
at high altitude or at high temperature.
– Engine malfunction or stalling.

Minor Repairs
287
Parking at the curb
Danger!
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.
fIf you are in doubt, have the wheel checked by
an expert, particularly if you suspect damage
on the inside.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Maintenance Note
Tire repairs are not permissible under any circum-
stances.
Wheel alignment, wheel balancingAs 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 weights 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
authorized Porsche dealer.
Danger!
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 remedied, you might lose
control of your vehicle which could cause
serious personal injury or death.
fStop the vehicle and check the tires.
fIf no cause for the fault can be found, drive ca-
refully to the nearest authorized Porsche dea-ler.
Wheels with Tire Pressure Monitoring
(TPM) sensorsBefore changing wheels, make sure that the
wheels are compatible with your vehicle’s TPM.
fCheck this with your authorized Porsche dea-
ler.
Removing and storing tiresfAfter changing, adjust tire pressure and torque
wheel bolts diagonally.
Please see the chapter “CHANGING WHEELS”
on Page 294.
fStore tires in a cool and dry place. Rotate peri-
odically to avoid flat spots.
fAvoid contact with petrol, oil and grease.
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 perfor-
mance are not affected by storage and age is
unfounded.
Chemical additives, which make the rubber elas-
tic, lose their effectiveness over the course of
time and the rubber becomes brittle and cracks.
Therefore, the tires, especially the spare tire,
should be inspected from time to time.
