Minor Repairs
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.
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.

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.

Minor Repairs
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 For safety reasons, don't use tire inflating
bottles.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on page 326.
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 pr essure 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-
inflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as po ssible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and
can lead to tire failur e. Under-inflation also
reduces fuel efficiency an d tire tread life, and may
affect the vehicle’s handling and stopping ability. Please note that the TPM is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPM low tire pressure
tell-tale.
For further information on the tire pressure
monitoring:
f
Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.
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 pressure can cause tires to over-
heat and thus be damaged – even invisibly. Hidden
tire damage is not eliminated by subsequently
correcting the tire pressure. Overloading
Danger!
Risk of damage to vehicle parts, loss of
control and serious pers onal injury or death.
f Do not overload your vehicle. Be careful about
the roof load.
f If you plan to load the vehicle, first correct the
tire pressure. 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
vehicle reactions and long braking distances.
Damage due to overloading is not covered by
the vehicle warranty.
Tire damage may also be caused by
overloading, and this damage is not covered by your tire warranty.
f Please see the chapter “LOADING INFORMA-
TION” on page 236.

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.

Changing a wheel
Danger!
Failure to follow these instructions may result
in serious personal inju ry or death to you or
to bystanders.
Before changing the wheel
f If you have a flat tire, move a safe distance off
the road. Turn the emergency flasher on and
use other warning devices to alert other
motorists.
f Do not park your vehicl e where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exhaust system could set
such materials on fire, thereby causing both
property damage and severe or fatal physical
injury.
f Passengers must not be in the vehicle when it
is jacked up.
f Before you change a wheel, be sure the ground
is level and firm. If necessary, use a board
under the jack to ensure that the jack does not
sink into the ground.
f Set the electric parking brake and block the
wheels opposite the flat tire on the other side
of the vehicle.
While operating the jack
f The jack is only to be used for changing a
wheel. Do not use it as a support to work under
the car. f
The car must be jacked up only at the
illustrated jacking points. Lifting at any other
place may damage the vehicle or may result in
personal injury. Never jack the car up by the
body or the bumpers.
f For safety reasons do not use tire inflating
bottles. Do not use co mmercially available
sealant bottles. Use only the tire inflating bottle
located in the luggage compartment.
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.
Sequence of operation Warning!
The jack must be used on ly to raise the car
for wheel changing. The jack must never be
used as a support to work underneath the
vehicle. If the jack is accidentally dislodged,
you or bystanders could suffer severe
personal injury.
f Never jack up other ve hicles or other loads
with the jack.
f Always place the car on stable supports if you
have to work under it. When working under the
vehicle, always use safety stands specifically designed for this purpose. f
Please use a suitable knee rest to protect your
clothing against soiling.

TowingCertain state statutes and local ordinances
prohibit towing with a chain, rope or even a tow
bar. In addition, damage to your vehicle may result
from improper precedures. Consult your
authorized Porsche dealer for details.
Flat bed towing is the pref
erred type of towing to
be used on Porsche vehicles.
Tips on driving
f Always observe the laws governing towing and
tow-starting.
f Exercise extreme care when your vehicle is
being towed.
– If a turn signal is operated when the ignition and emergency flasher is switched on, only the
turn signal on the corresponding side of the
vehicle lights up. The emergency flasher is
switched back on again when the turn signal is
switched off.
Warning!
Risk of accidents. No power assistance is
available on the towed vehicle when its
engine is not running. Greater force is
therefore required when braking and
steering.
f Exercise extreme care when your vehicle is being towed.
When the engine is not running, adequate
lubrication of the transmission is not guaranteed.
Observe the following points to avoid damage to
the transmission.
