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 pres-
sure increases rate of wear of the affected
tires and cause damage.
fAlways use an accurate tire pressure gage
when checking inflation pressures.
fDo not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to “Tech-
nical data”).
fPlease see the chapter “TIRE PRESSURE
PLATE” on Page 284.
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
measuring 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 immedi-
ately.
fUse only plastic valve caps.
fFor safety reasons, don't use tire inflating bottles.fPlease see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
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 TPM 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 TPM low tire pressure tell-ta-
le.For further information on the tire pressure moni-
toring:
fPlease see the chapter “SETTING TIRE PRES-
SURE MONITORING” on Page 132.
When tires are warm, the tire pressure is increa-
sed.
fNever 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 cor-
recting the tire pressure.

Speed code letterThe speed code letter indicates the maximum per-
missible speed for the tire.
This code letter is shown on the tire sidewall.
T = up to 118 mph (190 km/h)
H = up to 131 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
Tip on driving
Tires with a maximum speed rating that is lower
than the specified maximum vehicle speed may be
mounted only if they bear an M+S identification on
the tire sidewall.
fPlease note that in addition to the winter tires,
all-season and all-terrain tires are also subject
to speed limits and bear this identification.

Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids, folding
wedges) are only supplied with the vehicle if the
vehicle comes with a collapsible spare wheel or
full-size spare wheel as standard. Your authorized
Porsche dealer will be pleased to advise you.

Minor Repairs Maintenance Note
The jacking point on the vehicle must be free of
dirt.
1. Slightly loosen the wheel bolts of the wheel to
be changed.
2. Only set up the jack at the rear jacking point
designed for the purpose. The jack foot must
be in contact over its whole area and must be
positioned directly below the head piece.
Use a suitable support if necessary.
3. Hold jack still and wind it up until its head
enters the jacking point on the vehicle.
Only jack vehicle up until the wheel to be
changed is completely off the ground.
4. After lowering the vehicle, remove the jack.
Front jacking pointAccess to the jacking points differ according to
the respective vehicle equipment.
Jacking points
fSet up jack only at the points provided A or C.
Rear jacking pointThe rear jacking point is accessible after removing
the covering cap B from the sill cover.
Removing covering cap:
fPull out covering cap B at the bottom at the
rear.
Inserting covering cap:
Insert the covering cap B in the bottom guides and
push in completely until you feel the upper lugs
snap into place.
