Inflating tires on vehicles with air
suspension1. Pull up the seat cushion at loop A on the rear
left seat.
2. Pull seat cushion forward (arrow B).
3. Raise seat cushion vertically.4. Open Velcro fastening strip on the fastening
strap.
5. Take tire filling hose out of the bag.6. Remove cover A in footwell of the front passen-
ger seat.

B- Screw coupling for compressor connection
C- Pressure tester
D- Hand valve for tire filling
E- Air bleed screw
F- Filler connection for tire valve7. Screw screw coupling B into the compressor
connection (in footwell of the front passenger
seat).
8. 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.
9. Switch ignition on.
10.Press hand valve Duntil the correct tire pres-
sure is achieved.
Monitor the tire pressure with pressure tester
C during the inflation process.
11.Unscrew the screw coupling from the com-
pressor connection.
12.Unscrew filler connection from the tire valve.
13.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.

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 vehi-
cle type.
fDo not mount the spare wheel from your car on a different vehicle.Removing spare wheel
Warning!
Danger of injury if the spare wheel is
removed improperly.
fRemove the spare wheel only when the spare
wheel bracket is locked.
fRemove the spare wheel from the spare wheel
bracket with care. The wheel is very heavy (approx. 77 lbs. (35 kg)).
1. Unscrew all five wheel bolts.
2. Remove the top wheel bolt.
Remove assembly aid from the tool kit and
screw in instead of the wheel bolt.
Remove the remaining wheel bolts.
Fitting spare wheel
fInsert 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 centerd.
fPlease observe the chapter “TIRE PRES-
SURES, COLD” on Page 361.
fAfter mounting the wheel, tighten all five wheel
bolts to 111 ftlb. (150 Nm).

Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 361.
fPlease observe the chapter “REPLACING BUL-
BS” on Page 336.Adjustment
The adjustment is made with the vehicle ready to
drive and the fuel tank completely filled.
The driver's seat must be loaded by a person or 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 7.5 m (24.6 ft.) from the front lens of
the headlamp.The correct position of the cutoff is
7.5 cm (3.0 in.) at 7.5 m or 24.6 ft. (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
7.5 m (this value is a rounded down conversion
from the 25-foot distance typical of field aim using
a screen). The 7.5 m (24.6 ft.) distance is mea-
sured 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 vehi-
cle's longitudinal axis, flat, uniformly light in color,
unobstructed, and wide and high enough to ac-
commodate 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 vehi-
cle's headlamp spacing.
