Practical Tips, Emergency Service
Tire pressures
Warning!
Incorrect tire pressure causes increased tire
wear and adversely affects road handling.
fAlways use an accurate tire pressure gauge
when checking inflation pressures.
fDo not exceed the maximum tire pressure list-
ed on the tire sidewall.
Please observe the chapter “TIRE PRESSURE
PLATE” on Page 285.
fCold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
(68°F/20°C)
, when adjusting the inflation pres-
sure.
Avoid sunlight striking the tires before measur-
ing cold pressures, since the pressures would
rise from temperature influence.
fValve caps protect the valve from dust and dirt,
and thus from leakage.
Always screw caps tightly down.
Replace missing caps immediately.
fUse only plastic valve caps.
fDo not use commercially available sealant or
tire inflating bottles. Only use Porsche approved tire sealant.Each tire, including the spare (if provided), should
be checked every 2 weeks when cold (68°F/20°C)
and inflated to the inflation pressure recommend-
ed in this Owner's Manual or on the tire-pressure
plate.
If your vehicle has tires of a different size than the
size indicated in this Owner's Manual or on the tire-
pressure plate, 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 (TPC)
that illuminates a low tire pressure message when
one or more of your tires is significantly under-in-
flated. Accordingly, when the low tire pressure
message illuminates, you should stop and check
your tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly un-
der-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduc-
es fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPC 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 TPC low tire pressure mes-
sage.
fOn vehicles with tire pressure monitoring:
Please observe the chapter “TPC TIRE
PRESSURE MONITORING” on Page 109.
When tires are warm, the tire pressure is
increased.fNever 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 personal injury, loss of control and
damage to vehicle parts.
fDo not overload your vehicle. Be careful about
the roof load.
fIf 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.
fNever 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.
fPlease observe the chapter “LOADING INFOR-
MATION” on Page 242.
fPlease observe the chapter “TIRE PRESSURES
FOR COLD TIRES” on Page 290.

Practical Tips, Emergency Service
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.
fPlease adjust your driving style accordingly.
Installation of new tires should 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.
fUse only genuine Porsche metal valves.
fProtect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.
fUse only plastic valve caps.
Parking at the curb
Warning!
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 severe personal injury.
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.

A- Filler bottle
B- Filler hoseTire sealantThe tire sealant can be used to seal small cuts,
especially in the tire tread.
Sealing the tire with the tire sealant is only an
emergency repair, so you can drive to the next
workshop. Even with the tire air-tight, it may be
used only for short journeys in an emergency.The tire sealant and a compressor with pressure
tester can be found in the luggage compartment.
The tire sealant comprises:
– A filler bottle
– A filler hose
– A valve turner and
– A spare valve insert.
Danger!
Risk of accident.
fUse the tire sealant only in the case of cuts or
punctures no larger than 0.15 in. (4 mm).
fNever use the tire sealant if the rim is dam-aged.
Warning!
The sealant is highly flammable and harmful
to health.
fFire, naked flame and smoking are prohibited
when handling tire sealant.
fAvoid contact with skin, eyes or clothing.
fKeep tire sealant away from children.
fDo not inhale vapors.
In case of contact with the sealant:
fIf sealant gets on the skin or in the eyes,
thoroughly rinse the affected part of the body
off without delay.
fChange soiled clothing immediately.
fVisit a doctor immediately in the event of an
allergic reaction.
fIf sealant was swallowed, thoroughly rinse out
the mouth without delay and drink plenty of
water.
Do not induce vomiting.
See a doctor immediately.

Emergency Starting with Jumper
Cables If the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same. Both batteries must be 12 volt types.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.
The discharged battery must be correctly con-
nected to the vehicle’s electrical system.
fPlease observe the chapter “BATTERY” on
Page 258.
fPlease observe the chapter “EMERGENCY UN-
LOCKING OF THE LUGGAGE COMPARTMENT
LID” on Page 257.
Note
fDo not try to start the car by pushing or tow-
ing. Damage to the catalytic converters and
other components of the car may result.
Warning!
Risk of damage and serious personal injury
due to short circuit.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fEnsure that tools or conductive jewelery (rings,
chains, watch straps) do not come into contact
with the positive jumper cable or the positive
battery post.
fImproper hook-up of jumper cables can ruin
the alternator. Danger of caustic burns.
fDo not lean over the battery.
Danger of gas explosion.
fImproper use of booster battery to start a
vehicle may cause an explosion, resulting in
severe personal injuries.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at
23°F/–5°C.
Before connecting jumper cables, a frozen bat-
tery must be thawed out.
