Fabric, upholstery, carpets and
floor-mats fUse only a vacuum clea ner or a medium stiff
brush.
f Remove stains and spots with Porsche stain
remover.
To protect carpets, the Porsche range of accesso-
ries includes mats of the correct size and with the
appropriate fastening.
Warning!
Risk of an accident resulting in serious per-
sonal injury or death.
f Always check the movement of the pedals be-
fore driving and make sure that they are not ob-
structed by a floor-mat or any other object.
f Secure the floor-mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle - do not install them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you nonskid floor-mats of the correct size.
Cleaning fabric liningsfFabric linings on pillar s, convertible top liner
and sun blinds, etc. must be cleaned only
using suitable cleaning agents or a suitable dry
foam and a soft brush.Alcantara f Do not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush.
Heavy abrasion or rubbing when cleaning causes
a lasting change in the surface.
Cleaning when lightly soiled
f Wet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
f Wet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in.
Cleaning safety belts f Use mild detergent to clean soiled belts.
f When drying, avoid direct sunlight.
f Only use suitable cleaning agents.
f Do not tint or bleach the belts.
The belt fabric could be weakened, thus affec-
ting safety.

Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N. f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted in
the engine-compartment.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
f Your Porsche is equipped with an electronic ig-
nition system. When the ig nition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
f Always support your car with safety stands if it
is necessary to work under the car.
Jacks are not suitable for this kind of work.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
f Supplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
f Some countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.

Tires/Wheels The original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
For your safety remember the following:
– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original equip- ment wheels, be sure that they conform to
Porsche specifications for your model.
Only tires with the same make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
– The use of wheel rims and wheel bolts that do not meet specifications of the original factory
installed equipment will affect the safe opera-
tion of your vehicle.
– Before you plan on exchanging wheels, or snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer. Your
dealer has the technical information necessary
to advise you which wheel rims and wheel bolts
are compatible with the original factory instal-
lations.
Danger!
Risk of loss of contro l and serious personal
injury or death.
f If while driving, your vehicle experiences a sud-
den vibration or ride disturbance, and/or you
suspect that possible damage to your tires or
vehicle has occurred, you should immediately
reduce your speed without excessive use of
the brakes.
f Stop the vehicle as soon as possible, and in-
spect the tires.
If you cannot determine the cause for the dis-
turbance, have your vehi cle towed to the near-
est Porsche or tire dealer to have your vehicle
or tire(s) inspected.
f Continuing to operate the vehicle without cor-
rection could result in a loss of control and serious personal injury.
ExampleUniform Tire Quality GradingQuality grades can be fo und where applicable on
the tire sidewall between tread shoulder and max-
imum section width.
All passenger car tires must conform to Federal
Safety Requirements in a ddition to these grades.
Tr e a d w e a r
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific govern-
ment test course.
For example, a tire graded 150 would wear one
Page 216 of 284

214
Practical Tips, Emergency Service
and a half (1-1/2) times as well on the government
course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of
their use, however, and
may depart significantly fr om the norm due to var-
iations in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C and they represent the tire’s ability
to stop on wet pavement as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete.
A tire marked C may have poor traction perform-
ance.
Warning!
The traction grade assigned to this is based on
braking (straight-ahead) traction tests and does
not include cornering (turned) traction, accelera-
tion, hydroplaning or peak traction characteris-
tics.
Temperature A, B, C
The temperature grades ar e A (the highest), B and
C, representing the tire’s resistance to the gener-
ation of heat and its abilit y to dissipate heat when
tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperatur es can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehi
cle Safety Standard No.
109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
Warning!
The temperature grade for this tire is established
for a tire that is properly inflated and not overload-
ed.
Excessive speed, underinflation, or excessive
loading, either separately or in combination, can
cause heat buildup and possible tire failure, result-
ing in serious personal injury or death. Tire pressures
Warning!
Incorrect tire pressure causes increased tire
wear and adversely affects road handling.
This could lead to tire fa ilure, resulting in loss
of control, leading to serious personal injury
or death.
f Always use an accurate tire pressure gage
when checking inflation pressures.
f Do not exceed the maximum tire pressure list-
ed on the tire sidewall.
Please see the chapter “TIRE PRESSURE PLA-
TE” on Page 265. f
Cold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
(68 °F/20 °C)
, when adjusting the inflation
pressure.
Avoid sunlight striking the tires before measur-
ing cold pressures, since the pressures would
rise from temperature influence.
f Valve caps protect the valve from dust and dirt,
and thus from leakage.
Always screw caps tightly down.
Replace missing caps immediately.
f Use only plastic valve caps.
f Do not use commercially available sealant or
tire inflating bottles. Only use Porsche
approved tire sealant.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/ 20 °C)” on Page 267.

Each tire, including the spare (if provided) should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring (TPM)
that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-in-
flated. Accordingly, when the low tire pressure tell-
tale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TP M is not a substitute for
proper tire maintenance, and it is the driver’s re-
sponsibility to maintain correct tire pressure, even
if under-inflation has not reached the level to trig-
ger illumination of the TP M low tire pressure tell-
tale.
f On vehicles with tire pressure monitoring:
Please see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 151.
When tires are warm, the tire pressure is
increased. f
Never let air out of hot tires.
This could cause the tire pressure to fall below
the prescribed value.
Insufficient tire filling pressure can cause tires to
overheat and thus be damaged – even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.
Overloading
Danger!
Risk of damage to vehicle parts, loss of con-
trol and serious personal injury or death.
f Do not overload your vehicle. Be careful about
the roof load.
f If loading the vehicle also correct the tire pres-
sure. Tire pressure for loaded vehicle can be
found on the tire pressure plate and in the
chapter technical data.
f Never exceed the specified axle load.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous ve-
hicle reactions and long braking distances.
Damage due to overloading is not covered by the vehicle warranty.
f Please see the chapter “LOADING INFORMA-
TION” on Page 224.

G In vehicles with collapsible spare wheel: Size and tire pressure of the spare wheel.
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may build up between the
tires and the road. This phenomenon is
known as “hydroplane” and may cause par-
tial or complete loss of traction, vehicle
control or stopping ability.
f Reduce speed on wet surface to prevent this. Tire life Tire life depends on vari ous factors, i. e., road
surfaces, traffic and wea ther 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 wear The original equipment tires on your Porsche have
built-in tire wear indicato rs. 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 adja-
cent 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.
Snow tires lose their traction capability when their
tread depth falls below 5/32 in. (4 mm).
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.

Danger!
Driving on worn tires can result in loss of con-
trol of the vehicle an d could cause serious
personal injuries or death.
f Do not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause
severe personal injury.
f Specialized high performance tires on high
performance sports cars exhibit more wear
than those on a family sedan, or even a high
performance sedan.
Therefore, it is important to check your tire
pressure and condition at least every two weeks.
If you notice that tires are wearing unevenly, con-
sult your Porsche dealer.
Uneven wear may not always be due to improper
wheel alignment. It can be the result of individual
driving habits such as cornering at high speeds. If
the tire pressure is not checked and adjusted
regularly, abnormal tire wear can also occur.
Tire care f Avoid damaging tires and wheel rims.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
f Check tires for uneven wear and damage
before driving off.
f Remove imbedded material.
f Replace worn or damaged tires immediately.
f Keep oil, fuel, brake fluid, etc. away from tires.
f Replace missing valve stem caps.
f Keep tires inflated correctly.
f Wash tires when washing the vehicle. Also
clean inner side of wheels.
f Do not use abrasive cleaners when washing
the wheels.
f Check wheel rims for corrosion.
f Remove road salt, if driving in winter.
Tire damage, puncture High-pressure cleaning units can damage the
tires.
f Please see the chapter “HIGH-PRESSURE
CLEANING UNITS, STEAM CLEANERS” on
Page 203.
f Check tires for imbedded material, cuts, punc-
tures, cracks and bulges (side wall) before driv-
ing off.
In case of tire damage, where it is uncertain wheth-
er there is a break in the ply with all its conse-
quences or tire damage caused by thermal or me-
chanical 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 replaced 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.

Practical Tips, Emergency Service
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
f Check tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
f After driving off road, examine tires for signs
of damage such as cuts, tears, bulges or for-
eign objects stuck in the tread. Replace a dam-
aged tire if necessary.
f Cross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
f In cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.
Tire replacements If in doubt, contact your Porsche dealer.
Use only tire makes and types approved 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 make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Use tires with “ZR” quality standards. There
are currently no standards concerning tire
strength at speeds above 150 mph (240 km/h).
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 tires are not permissible.
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). If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different
tread depth of the other tires.
This happens especially if only rear tires are re-
placed. However, this condition disappears as the
new tires are broken in.
f
Please adjust your driving style accordingly.
Installation of new tires sh ould only be done by a
qualified tire technician.
Valves
Rubber valve stems must be replaced every time
a tire is replaced.
For metal valves, the installation and replacement
instructions must be observed.
f Use only genuine Porsche metal valves.
f Protect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.
f Use only plastic valve caps.
