Changing a wheel with removal of 17 mm
spacer
Danger!
Risk of accident if the spacers are not
removed before mounting 18 inch tires or
collapsible spare wheel.
f17 mm spacers are always to be removed
before mounting 18 inch tires or a collapsible
spare wheel, because the wheel cannot be fitted 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 see the
chapter “SPACERS” on Page 293.

Minor Repairs
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
Management (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 fil-
ling 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.
Checking tire pressure with a pressure
gage1. Remove the valve stem cap from the tire.
2. Press the pressure gage 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 gage.
3. Read the tire pressure on the gage stem and
compare it to the permissible tire pressure.
This information can be found on the tire pres-
sure plate in the left door aperture.
Please see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
4. Remove the pressure gage.

hose can become hot during the inflation
process.
fWear gloves.
5. Switch on compressor.
The required filling pressure will be reached
after a few minutes.
6. Switch off compressor.
7. Check filling pressure with pressure tester.
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.
2. Open air bleed screw on the filling hose until
the correct filling pressure is achieved.

Spare wheel
Warning!
Risk of accident. The wheel and tire size and
the tire quality of the spare wheel and normal
wheel may differ.
If a spare wheel that differs from the normal
tires is used, this may impair the driving
behavior.
fThe 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
Management (PSM) system.
fIf the tire on the spare wheel is older than
4 years, the spare wheel should be used only
in the event of a flat.
fAvoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) if the mounted spare wheel differs
from the other three wheels on the car. This
maximum speed must not be exceeded
because of altered driving characteristics and
for reasons of wear.
fDo not use a spare wheel from a different
vehicle type.
fDo not mount the spare wheel from your car on a different vehicle.Removing spare wheel from bracket
Warning!
Danger of injury if the spare wheel is
removed improperly.
fRemove the spare wheel only when the spare
wheel bracket is locked.
