Storing your PorscheIf you intend to store your Porsche for a prolonged
period, please consult your authorized Porsche
dealer. The staff will be glad to advise you on the
most suitable and necessary methods.
fClean your vehicle thoroughly inside and out-
side. Clean the engine compartment. The un-
der carriage and chassis components should
be free of dirt and salt deposits.
fFill up the fuel tank.
fChange the oil and oil filter, and run the engine
for several minutes.
fIncrease the tire pressure to 58 psi (4 bar).It is
not recommended to lift the vehicle, due to the
possibility of corrosion on shock absorber pis-
ton shafts.The vehicle should be moved slight-
ly, approximately every four weeks, to prevent
flat spot on the tires.Climate control
The air conditioning system should be in good
working condition and fully charged.
Windshield/Headlight washer
fCheck and correct antifreeze/cleaning solution
level as necessary.
Electrical system
fRemove the battery from the vehicle and store
it in a cool dry place, not on a cement floor.
When the battery is disconnected, the alarm
system is deactivated.
fRecharge the battery every 3 months. If the
battery remains in the vehicle with the cables
connected, it is necessary to check, remove
and recharge the battery every 2-3 weeks.
Do not fast charge the battery.
fPlease observe the chapter “CHARGE STATE”
on Page 312.Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs.
(500 grams) each placed on the floor carpets.
Windows, doors, lids and roof must be closed.
The air vents should be opened.

Practical Tips, Minor Repairs

Tire carefAvoid damaging tires and wheel rims.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
fCheck tires for uneven wear and damage be-
fore driving off.
fRemove imbedded material.
fReplace worn or damaged tires immediately.
fKeep oil, fuel, brake fluid, etc. away from tires.
fReplace missing valve stem caps.
fKeep tires inflated correctly.
fWash tires when washing the vehicle. Also
clean inner side of wheels.
fDo not use abrasive cleaners when washing
the wheels.
fCheck wheel rims for corrosion.
fRemove road salt, if driving in winter.
Tire damage, puncturefPlease observe the chapter “HIGH-PRESSURE
CLEANING UNITS” on Page 257.
Danger!
Risk of accident due to hidden tire damage.
Tires may burst, especially at high speeds
causing loss of control of the vehicle, which
may result in severe personal injury or death.
fCheck tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
fAfter driving off road, examine tires for signs
of damage such as cuts, tears, bulges or for-
eign objects stuck in the tread. Replace a dam-
aged tire if necessary.
fCross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
fIn cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Por-sche dealer.In case of tire damage, where it is uncertain whe-
ther there is a break in the ply with all its conse-
quences or tire damage caused by thermal or me-
chanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
If one faulty tire is replaced it should be noted that
the difference in tread depth on one axle must not
exceed 30%. Handling inconsistencies may result.
fPerform a visual inspection if necessary.

Practical Tips, Minor Repairs
Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 350.
fPlease observe the chapter “REPLACING BUL-
BS” on Page 328.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 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
7.5 m (this value is a rounded down conversion
from the 25-foot distance typical of field aim using
a screen). The 24.6 ft. (7.5 m) 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.
