Practical Tips, Minor Repairs
Tire pressures
Danger!
Risk of accident.
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires and cause damage. Always use an
accurate tire pressure gauge when checking
inflation pressures.
fDo not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to “Tech-
nical data“).
fCold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
68°F (20°C), when adjusting the inflation pres-
sure. Avoid sunlight striking the tires before
measuring cold pressures, since the pressures
would rise from temperature influence.
fValve caps protect the valve from dust and dirt,
and thus from leakage. Always screw caps
tightly down. Replace missing caps immedi-
ately.
fFor safety reasons, don't use tire inflating bot-tles.
fPlease observe the chapter “TIRE PRES-
SURES, COLD” on Page 385.Each tire, including the spare (if provided), should
be checked every 2 weeks when cold (68°F/20°C)
and inflated to the inflation pressure recom-
mended in this Owner's Manual or on the tire-pres-
sure plate.
If your vehicle has tires of a different size than the
size indicated in this Owner's Manual or on the tire-
pressure plate, you should determine the proper
tire inflation pressure for those tires.
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring that illu-
minates a low tire pressure message when one or
more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure message
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the tire pressure monitoring is not
a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached
the level to trigger illumination of the tire pressure
monitoring low tire pressure message.
For further information on the tire pressure moni-
toring:
fPlease observe the chapter “TIRE PRESSURE
MENU” on Page 104.When tires are warm, the tire pressure is
increased.
fNever let air out of hot tires. This could cause
the tire pressure to fall below the prescribed
value.
Insufficient tire pressure can cause tires to over-
heat and thus be damaged – even invisibly. Hidden
tire damage is not eliminated by subsequently cor-
recting the tire pressure.
Overloading
Danger!
Risk of personal injury, loss of control and
damage to vehicle parts.
fDo not overload your vehicle. Be careful about
the roof load.
fIf loading the vehicle also correct the tire pres-
sure. Tire pressure for loaded vehicle can be
found on the tire pressure plate and in the
chapter technical data.
fNever exceed the specified axle load.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous vehi-
cle reactions and long braking distances.
Damage due to overloading is not covered by the vehicle warranty.
fPlease observe the chapter “LOADING INFOR-
MATION” on Page 213.

Practical Tips, Minor Repairs
303
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
before 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 285.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases increases risk of a tire failure and
resulting loss of control. Furthermore, low
tire pressure increases rate of wear of the
affected tires.
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
whether there is a break in the ply with all its con-
sequences or tire damage caused by thermal or
mechanical 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.

Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 385.
fPlease observe the chapter “REPLACING BUL-
BS” on Page 360.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 meas-
ured 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.
