Maintenance and Car Care
Cleaning headlights, lights, interior and
exterior plastic components, adhesive
foils, radar sensor for adaptive cruise
control and rearview cameraObserve the following points:
fUse only clean water and a little dishwashing
liquid or interior window cleaner to clean
headlights, lights, plastic components
and surfaces.
Use a soft sponge or a soft, lint-free cloth.
Note
An interior window cleane r can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container!).
We recommend Porsche interior window cleaner.
f Gently wipe the surface without applying
too much pressure.
f Do not clean when dry.
f Never use other chemical cleaners
or solvents.
f Rinse cleaned surfaces with clear water.
Alloy wheelsMetal particles (e.g. brass or copper in brake
dust) must not remain too long on alloy wheels.
Contact corrosion can cause pitting.
Note
Cleaners with an oxide-removing effect or
wrong pH value, as are commonly used for
other metals, as well as mechanical tools and
products, will damage the oxide layer and are
therefore unsuitable.
fUse only cleaners for alloy wheels
(pH value 9.5). Products with the wrong
pH value can destroy the protective layer
on the wheels.
We recommend Porsche cleaner for light
alloy rims.
f If possible, wash the wheels every two weeks
with a sponge or washing brush. If the wheels
are exposed to road salt, grit or industrial dust,
weekly cleaning is necessary.
f Every three months, after cleaning, treat the
wheels with car wax or an acid-free grease
(e.g. Vaseline).
Rub the grease in well with a soft cloth.
f Please see the chapter “CLEANING IN CAR
WASHES” on page 271.
Danger!
Danger of accident resulting in serious
personal injury or death if cleaning agents
(e.g. wheel cleaning agents) come into
contact with the brake discs. The resulting
film on the brake discs can impair braking
performance.
f Make sure that no clea ning agent comes into
contact with the brake discs.
f If cleaning agent has come into contact with
the brake discs, clean the brake discs
thoroughly with a strong jet of water.
f Paying attention to any road users behind you, dry the brake discs by applying the brakes.
Stainless steel tailpipesStainless steel tailpipes can discolor due to
soiling, strong heat and combustion residues.
The original shine can be achieved again using
commercially available metal lustre paste or metal
polish.

Maintenance and Car Care
Cleaning air bag covers
Danger!
Risk of serious or fatal injury from impaired
operation of the air bag system caused by
incorrect cleaning.
f While it is appropriate to use normal surface
cleaning methods on the interior of your
vehicle, do not undertake deep cleaning of air
bag-related components, such as the
padded covers on the steering wheel,
the underside of the instrument panel,
front seats, roof pillars, roof liners and the
rear interior trim panels, and around the
seat backrest.
f Have your authorized Porsche dealer to clean these components.
Cleaning fabric liningsfFabric linings on pillars, roofliner and sun
blinds, etc. must be cleaned only using
suitable cleaning agents or a suitable dry
foam and a soft brush.
Alcantara careDo not use leather care products to
clean Alcantara.
For regular care, it is sufficient to clean the
cover with a soft brush.
Strong abrasion or rubbing when cleaning will
produce a lasting change to 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 diluted
white spirit and dab the dirt from the outside
in.Cleaning the seat beltsfUse 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 affecting safety.
Storing your PorscheIf you wish to keep your Porsche off the road for
a lengthy period, we recommend that you contact
your authorized Porsche dealer.
They will be glad to advise you about the
necessary measures, e.g. corrosion prevention,
care, maintenance and storage.
Further important information on laying up your
Porsche can be found in other sections.

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.
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
cautious of devices such as hot water heaters
which ignite a flame intermittently.
f Before working on any part in the engine
compartment, 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 the engine at all
times while it is running. If you have to work on
the engine while it is running, always put the
parking brake on and put 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 fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
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
engine off and exercise extreme caution.
f Your Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage 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. The jack
supplied with the car is not adequate for this
purpose.
Switch off level control of air suspension and
height adjustment.
Please see the chapter “RAISING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 290.
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.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive). f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
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
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
f Supplies of fluids, e.g. engine oil, washer fluid,
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
appropriate regulations.
f Some countries require additional tools and
special spare parts to be carried in your
vehicle. Please make enquiries before driving
abroad.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not
supplied as standard with the vehicle. Your
authorized Porsche dealer will be pleased to
advise you.

Minor Repairs
Tires and WheelsThe 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 equipment wheels, be su re 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
operation of your vehicle and affect warranty
coverage.
– 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 installations.
Danger!
Risk of loss of control and serious personal
injury or death.
f If while driving, your vehicle experiences a
sudden 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
inspect the tires.
If you cannot determine the cause for the
disturbance, have your vehicle towed to the
nearest Porsche or tire dealer to have your
vehicle or tire(s) inspected.
f Continuing to operate the vehicle without
correction could result in a loss of control and serious personal injury.
ExampleUniform Tire Quality GradingQuality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.

Minor Repairs
281
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific
government test course. For example, a tire
graded 150 would wear one 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 from the
norm due to variations in driving habits, service
practices and differences 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
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Warning!
The traction grade assigned to this is based
on braking (straight-ahead) traction tests
and does not include cornering (turned)
traction, acceleration, hydroplaning or peak
traction characteristics. Temperature A, B, C
The temperature grades are A (the highest), B and
C, representing the tire's resistance to the
generation of heat and it
s ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperatures can cause the
material of the tire to de generate and reduce tire
life, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109.
Grades B and A represent higher levels of
performance on the labora tory 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 overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combin ation, can cause heat
buildup and possible tire failure, resulting
loss of control, leading to serious personal
injury or death.
Tire pressures
Danger!
Risk of accident.
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
pressure increases rate of wear of the
affected tires and cause damage.
f Always use an accurate tire pressure gage
when checking inflation pressures.
f Do not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to
”Technical data“).
f Please see the chapter “TIRE PRESSURE
PLATE” on page 283.
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 measuring cold pressures, since the
pressures would rise from temperature
influence.

B Vehicle load limit Is the maximum total weight limit specified of
the load (passengers and cargo) for the
vehicle. This is the maximum weight of
passengers and cargo that can be loaded into
the vehicle.
Please see the chapter “LOADING
INFORMATION” on page 236. C Original tire size
Size of tires mounted at the factory.
D Recommended cold tire inflation pressure These values are for cold tires (68 °F/20 °C).
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.
