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 vehicle. If the jack is
accidentally dislodged, you or bystanders
could suffer severe personal injury.
fNever jack up other vehicle or other loads with
the jack.
fAlways place the car on stable supports if you
have to work under the car.
When working under the vehicle, always use
safety stands specifically designed for this pur-pose.
Tool KitTo o l b o x A and compressor with pressure tester
on non-air suspension vehicles are located under
the cargo area.
Notes on operation
On vehicles with a collapsible spare wheel or full-
size spare wheel as standard, the screwdriver is
stored in the handle of the wheel bolt wrench.
A-CompressorCompressorOn vehicles without level-control systems, there is
an additional compressor with pressure tester
under the loadspace floor.
fPlease see the chapter “CHECKING TIRE PRES-
SURE WITH A PRESSURE GAGE” on Page 306.
On vehicles with level control, you can use the
compressor of the level-control system to fill the
tires.
The bag with the tire filling hose is located under
the loadspace floor in the spare-wheel recess.

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.

Inflating tires on vehicles without air
suspension1. Please follow the operating instructions on the
compressor.
2. Screw filler hose of the compressor onto the
tire valve.
3. Remove cover A of the engine-compartment
cover.
Please see the chapter “CONNECTING
JUMPER CABLES” on Page 324.
+ = Positive terminal for emergency starting
with jumper cables
– = Grounding point for emergency starting
with jumper cables4. Connect clamps of the compressor to the
terminals for emergency starting with jumper
cables.
Always observe the following sequence:
– Open the cap of the positive terminal for emer-
gency starting with jumper cables (+).
– Connect positive lead (red) to the positive
terminal for emergency starting with jumper
cables (+).– Connect negative lead (black) to the negative
terminal for emergency starting with jumper
cables (
–).
Warning!
Danger of burning. The compressor filler
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.

Inflating tires on vehicles with air
suspensionThe bag with the tire filling hose is located under
the loadspace floor in the spare-wheel recess.
1. Take tire filling hose out of the bag.
2. Remove cover in footwell of right front seat.

C-Pressure tester
D- Hand valve for tire filling
E-Air bleed screw
F- Filler connection for tire valve3. Screw screw coupling B into the compressor
connection (in footwell of the front passenger
seat).
4. Screw filler connection F onto the tire valve.
Warning!
Danger of injury and risk of damage if the
operating unit is used improperly.
fUse this operating unit only to inflate or to bleed air from the tires of this vehicle.
5. Switch ignition on.
6. Press hand valve D until the correct tire pres-
sure is achieved.
Monitor the tire pressure with pressure tester
C during the inflation process.
7. Unscrew the screw coupling from the com-
pressor connection.
8. Unscrew filler connection from the tire valve.
9. Stow tire filler hose in the bag.
Note on operation
The compressor features a protective function
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
C while correcting the tire pressure.

Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
fPlease see the chapter “REPLACING BULBS”
on Page 326.Adjustment
The adjustment is made with the vehicle ready to
drive and the fuel tank completely filled.
T h e d r i ve r ' s s e a t m u s t b e l o a d e d b y a p e r s o n o r a
165lbs. (75kg) weight and the tire pressures must
meet the prescribed values. After being loaded,
the car must be rolled a few meters so that the
suspension can settle.
For checking the headlight adjustment, the verti-
cal position of the cutoff of the lowbeam (see fig.)
has to be projected on a vertical screen (wall) in
distance of 24.6 ft. (7.5 m) from the front lens of
the headlamp.The correct position of the cutoff is
3.0 in. (7.5 cm) at 24.6 ft. or 7.5 m (0.4°) below
a horizontal line, x cm from ground to the center
of the headlamp lens.
Lateral adjustment of the headlights should be
carried out at a specialist workshop with an optical
adjustment unit.
Distance
Visual aim shall be performed at not less than
24.6 ft. (7.5 m) (this value is a rounded down con-
version from the 25-foot distance typical of field
aim using a screen). The 24.6 ft. (7.5 m) distance
is measured from the headlamp lens to the
viewing screen.
Floor
The surface upon which the vehicle rests is flat
and approximately level.
Screen
The screen upon which headlamp beams are pro-
jected is perpendicular to the floor and the
vehicle's longitudinal axis, flat, uniformly light in
color, unobstructed, and wide and high enough to
accommodate the vehicle beam patterns to be
aimed.
The screen should be wide enough to provide at
least 3.3 ft. (1 m) of space outboard of the
vehicle's headlamp spacing.
