corrected on this display.
The tire pressure to be corrected (refill pressure)
is indicated on the displayed wheel.
Example: If “–1.5 psi (–0.

Maintenance and Car Care
253
Technical ModificationsfModifications may be carried out on your
vehicle only if approved by Porsche.
This ensures that your Porsche will remain
reliable and safe to drive, and that it will not be
damaged as a result of the modifications.
Your authorized Porsche dealer will be pleased
to advise you.
Safety notes!
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
authorized Porsche dealer or a qualified
specialist workshop. Safety-related
accessories should only be used if they are
from the Porsche Tequipment range or are
tested and approved by Porsche. Your
authorized Porsche dealer will be pleased to
advise you and answer any questions you may
have.
However, the use of other parts or
accessories may adversel y affect the safety
of your vehicle, and Porsche can take no
responsibility for any loss or damage caused
by their use.
Even if the supplier of other accessories or
parts is a recognized supplier, the safety of
your vehicle may still be affected if such items
are installed.
Due to the large variety of products offered in the accessory market, it is not possible for
Porsche to inspect and approve every one.
f In addition, please note that the use of
replacement parts that are not genuine
Porsche parts or approved parts, or the use of
accessories not approved by Porsche may
also detrimentally affect your vehicle warranty.
f Check your vehicle regularly for signs of
damage. Damaged or missing aerodynamic
components, such as spoilers or underbody
panels, impair vehicle handling and must
therefore be replaced immediately.
Radiator fanFor information on radiator fans:
fPlease see the chapter “RADIATOR FANS” on
page 258.
Warning!
Danger of injury. After the ignition is
switched off, the engine compartment and
coolant temperatures are monitored for
approx. 30 minutes. During this period, and
depending on temperature, the radiator fan
may continue to run or start to run.
f Carry out work in these areas only with the engine off and exercise extreme caution.
Measurements on test standsPerformance test
Performance tests on roller-type test stands are
not approved by Porsche.
Brake tests
Brake tests must be performed only on roller-type
test stands.
The following limit values must not be exceeded
on roller-type test stands:
– Test speed 4.7 mph (7.5 km/h)
– Test duration 20 seconds
Testing the electric parking brake
Electric parking brake tests on the brake test
stand must only be performed with the ignition
switched on and with the manual gearshift lever in
neutral or the Porsche Doppelkupplung selector
lever in position N.
The vehicle switches auto matically to brake test
stand mode, in which the electric parking brake
can be tested.
The message “Electric parking brake in service
mode” appears on the multi-function display in the
instrument panel.
Balancing wheels on the vehicle
During finish balancing of the wheels, the entire
vehicle must be lifted and the wheels must be free
to turn.

Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may bu ild up between the
tires and the road. This phenomenon is
known as “hydroplane” and may cause
partial or complete loss of traction, vehicle
control or stopping ability.
f Reduce speed on wet surfaces to prevent this.
Tire lifeTire life depends on various factors, i.e., road
surfaces, traffic and weather conditions, driving
habits, type of tires and tire care.
f Inspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.Tire wearThe original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the tires.
We recommend, however, that you do not let the
tires wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.
Minor Repairs
285
In case of tire damage, where it is uncertain
whether there is a break in the ply with all its
consequences or tire damage caused by thermal
or mechanical overloading due to loss of pressure
or any other prior damage, we recommend that
the tire be replaced for safety reasons.
If one faulty tire is replac ed it should be noted that
the difference in tread depth on one axle must not
exceed 30%. Handling inconsistencies may result.
f Perform a visual inspection if necessary.Tire replacementsfUse only tire makes and types tested by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same manufacturer and
with the same specific ation code (e.g. “N0”,
“N1”…) should be mounted on the vehicle.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Tires should be replaced no less than on one axle
at the time. Only tires of the same make and type
must be used. Mixed tire s are not permissible and
will affect vehicle performance, safety, and can
affect vehicle warranty. Porsche dealers can recommend the most current
replacement tire options for your vehicle.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km).
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.
If new tires are installed only on one axle, a
noticeable change in hand ling occurs due to the
different tread depth of the other tires. This
happens especially if only rear tires are replaced.
However, this condition disappears as the new
tires are broken in.
f Please adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
f Use only plastic valve caps.
f The rubber valves must be replaced whenever
the tires are changed.
f The fitting and replacement specifications
must be observed for metal valves.
f Only use Original Porsche metal valves.
f Protect the valve inserts against soiling with
valve caps. Soiled valve inserts can cause a
gradual loss of air.
Parking at the curb
Danger!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause
hidden 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 After such an impact, have the wheel checked
by an expert.
f If 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
circumstances.
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.
288
Minor Repairs
Snow chains
Warning!
Risk of damage to body, axle or brake
components.
f Use only the fine-link snow chains recom-
mended and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
f Please see the chapter “WHEELS, TIRES” on
page 325.
f Follow instructions issued by the supplier of the chains.
Fit snow chains only on the rear axle.
f Remove spacers if snow chains are mounted.
f Before fitting chains, remove accumulated ice
and snow from the wheel well.
f Vehicles with snow chains must not be driven
faster than 30 mph (50 km/h) .
Different states and countr ies have varying statu-
tory requirements regarding maximum speed.
f Check with local authorities for possible
restrictions.
f Remove chains as soon as the roads are free
of ice and snow.
