CompressorOn vehicles without level-control systems, there is
an additional compressor with pressure tester un-
der the loadspace floor.
On vehicles with level control, you can use the
compressor of the level-control system to fill the
tires.
The filler hose required for this purpose can be
found under the left rear seat.
fPlease observe the chapter “FOLDING REAR
SEATS FORWARD” on Page 37.
fPlease observe the chapter “INFLATING TIRES
ON VEHICLES WITHOUT AIR SUSPENSION” on
Page 295.
Wheel BoltsfAlways clean the wheel bolts before installing.
Maintenance note
fWheel bolts must not be greased.
fReplace damaged wheel bolts.
Only use the original Porsche wheel bolts spe-
cially designed for this vehicle type.Tightening torque
Tightening torque of the wheel bolts 118 ftlb.
(160 Nm).
Security wheel boltsThe adapter (wrench socket) for the security
wheel bolts is located in the tool box.
To loosen or tighten the wheel bolt with anti-theft
protection, the adapter must be used between the
wheel bolt and the wheel bolt wrench.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
Note on operation
If the wheels have to be removed at the workshop,
please do not forget to hand over the socket for
the security wheel bolts along with the car key.

Practical Tips, Minor Repairs
Changing Wheels
Warning!
Failure to follow these instructions may result
in serious personal injuries to you or to by-
standers.
Before changing the wheel
fIf 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 motor-
ists.
fDo not park your vehicle 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.
fPassengers must not be in the vehicle when it
is jacked up.
fBefore you change a wheel, be sure the ground
is level and firm. If necessary, use a board un-
der the jack to ensure that the jack does not
sink into the ground.
fSet the parking brake and block the wheels op-
posite the flat tire on the other side of the vehi-
cle.While operating the jack
fThe jack is only to be used for changing a
wheel. Do not use it as a support to work under
the car.
fThe car must be jacked up only at the illustrat-
ed jacking points.Lifting at any other place
may damage the vehicle or may result in per-
sonal injury. Never jack the car up by the body
or the bumpers.
fFor safety reasons do not use tire inflating bot-
tles. Do not use commercially available sealant
bottles.Use only the tire inflating bottle locat-
ed in the luggage compartment.
Sequence of operation
Warning!
The jack must be used only to raise the car
for wheel changing.The jack must never be
used as a support to work underneath the ve-
hicle. If the jack is accidentally dislodged,
you or bystanders could suffer severe per-
sonal injury.
fNever jack up other vehicles or other loads
with the jack.
fAlways 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.
fPlease use a suitable knee rest to protect your
clothing against soiling.

10 minutes.
If the tire pressure is less than 19 psi/1.3 bar,
do not continue driving.
16.Consult your authorized Porsche dealer.Care Instructions
After drying, any sealant that emerges can be
peeled off like a film.

Warning!
Risk of accident.
fThe collapsible spare wheel must be used only
over short distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1.6 mm high).
fNever deactivate the Porsche Stability Man-
agement (PSM) system.
fAvoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) and must not be exceeded be-
cause of altered driving characteristics and for
reasons of wear.
The tread depth of the spare wheel is subject
to the same laws as the original tires.
fDo not use a collapsible spare wheel from a
different vehicle type.
fDo not mount the collapsible spare wheel from
your car on a different vehicle.fOnly fit one collapsible spare wheel on the ve-
hicle at a time.
fOn vehicles with air suspension, use the tire fill-
ing connection A only to inflate the collapsible
spare wheel.
fTo avoid damage, do not use automatic car
washes when the spare wheel is installed.
After using the collapsible spare wheel
fRelease air by unscrewing the valve insert.
Notes on operation
The tire will revert to its original shape only after
several hours. Only then can it be stowed in the
spare wheel recess in the luggage compartment.
There is a plastic sheet in the tool box to store the
damaged wheel.
Maintenance note
The collapsible spare wheel must be repaired only
by the manufacturer.
fPlease consult your authorized Porsche dealer
if the collapsible spare wheel is defective.

Note on operation
fDo not press too hard or force the valve stem
sideways, or air will escape.
If the sound of air escaping from the tire is
heard, reposition the pressure gauge.
3. Read the tire pressure on the gauge stem and
compare it to the permissble tire pressure.
This information can be found on the tire pres-
sure plate.
Please observe the chapter “TIRE PRESSU-
RES, COLD” on Page 350.
4. Remove the gauge.
fPlease observe the chapter “TIRE PRESSURE”
