Changing a wheel with removal of 17 mm
spacer
Danger!
Risk of accident if the spacers are not re-
moved before mounting 18 inch tires or col-
lapsible spare wheel.
f17 mm spacers are always to be removed be-
fore mounting 18 inch tires or a collapsible
spare wheel, because the wheel cannot be fit-ted correctly. Caution!
Risk of damage to wheel housings if the
spacers on the rear axle are not removed be-
fore fitting the snow chains.
f17 mm spacers must always be removed from the rear axle when snow chains are to be fitted.
fRemove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.
fIt is not necessary to use a assembly aid for
mounting a wheel or spare wheel of the same
quality.
fFor information on the spacers: Please
observe the chapter “SPACERS” on Page 314.
Puller1. Remove plastic covers from the wheel nuts
with the puller D from the toolbox.2. Remove wheel nuts.

screw in instead of the wheel bolt.
6. Fit wheel.
7. Use the wheel bolts A with which the spacer
was fastened to mount the wheel.
Insert wheel bolts and tighten by hand.
Remove assembly aid and screw in remaining
wheel bolt.
Initially tighten bolts in diagonally opposite
sequence so that the wheel is centred.8. Inflate the tire if necessary.
Please observe the chapter “TIRE PRES-
SURES, COLD” on Page 385.
On vehicles with Tire Pressure Monitoring:
Please observe the chapter “TIRE PRESSURE”
on Page 102.
9. Lower the car and remove the jack.
10.Tighten wheel bolts in diagonally opposite
sequence.
Maintenance note
fImmediately after changing a wheel, use
a torque wrench to check the prescribed
tightening torque of the wheel bolts
(160 Nm/118 ftlb.).
fSpacer, steel nuts, and plastic covers should
be stored together.
Fitting the 17 mm spacer1. Remove wheel.
2. Fit the spacer with the wheel bolts A used to
fasten the wheel.
Tightening torque: 160 Nm (118 ftlb.)
3. Fit wheel.
To d o t h i s use the original wheel nuts for
fastening the wheels.
Tightening torque: 160 Nm (118 ftlb.)
Place plastic covers onto the steel nuts.
Note
There is no anti-theft protection for the wheel nuts.

Collapsible spare wheelThe collapsible spare wheel is fastened under the
floor in the luggage compartment.
On vehicles with 17 mm spacers:
fBefore fitting a collapsible spare wheel on the
rear axle always remove the corresponding
spacer.
For information on the spacers: Please
observe the chapter “SPACERS” on Page 314.
For information about removing the spacers:
Please observe the chapter “CHANGING A
WHEEL WITH REMOVAL OF 17 MM SPACER”
on Page 323.
1. Take out rotary knob A and put it on bolt B.
2. Unscrew the screw and take out the collapsible
spare wheel.
3. Mount the collapsible spare wheel on the vehi-
cle before inflating it. Leave the car jacked up.
Please observe the chapter “LIFTING THE
VEHICLE WITH A JACK” on Page 319.
4. Inflate the tire.
Please observe the chapter “TIRE PRES-
SURES, COLD” on Page 385.
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, 1/16 in. (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
because 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
vehicle 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.

326
Practical Tips, Minor Repairs 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.

Checking tire pressure with a pressure
gauge1. Remove the valve stem cap from the tire.
2. Press the pressure gauge onto the valve stem.
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 PRES-
SURES, COLD” on Page 385.
4. Remove the pressure gauge.
fPlease observe the chapter “TIRE PRESSURE”
on Page 102.
Inflating tires on vehicles without air
suspension1. Open front lid of the compressor.
2. Screw filler hose A of the compressor onto the
tire valve.3. Remove cover A of the engine-compartment
cover.
Please observe the chapter “CONNECTING
JUMPER CABLES” on Page 356.

Always observe the following sequence:
– Open the cap of the positive terminal for emer-
gency starting with jumper cables (+).
– Connect positive lead (red) B to the positive
terminal for emergency starting with jumper
cables (+).
– Connect negative lead (black) C to the nega-
tive terminal for emergency starting with
jumper cables (

hose can become hot during the inflation
process.
fWear gloves.
5. Switch on compressor with switch D.
The required filling pressure will be reached
after a few minutes.

7. Check filling pressure with pressure tester E.
Then reduce tire pressure or add more air if
necessary.
Recheck the filling pressure.
8. Unscrew filler hose of the compressor.Reducing filling pressure on vehicles
without air suspension1. Switch off compressor with switch D.
2. Open air bleed screw F until the correct filling
pressure is achieved.

against overheating and switches itself off auto-
matically if necessary. The compressor must cool
down for a few minutes after automatic deactiva-
tion.
Reducing tire pressure on vehicles with
air suspensionfOpen air bleed screw E until the correct tire
pressure is achieved.
Monitor the tire pressure with pressure tester
