Loading InformationDefinitionsThe towing capacity (gross weight of the trailer)
is the sum of the trailer's empty weight and the
weight of the load.
The vertical coupling load is the weight that the
trailer drawbar exerts on the trailer coupling of the
vehicle.
The rear-axle load is the vehicle weight on the
rear axle plus the weight of the transported load
and the vertical coupling load of the trailer.
The gross weight of the vehicle and trailer is
the sum of the weight of the towing vehicle and the
weight of the trailer.
The Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids, emergency tools, and spare tire
assembly. This weight does not include passen-
gers and cargo.
The Gross Vehicle Weight is sum of the curb
weight and the weight of passengers and cargo
combined.
The Gross Vehicle Weight Rating is the maxi-
mum total weight of vehicle, passengers, lug-
gage, hitch, trailer tongue load and optional equip-
ment.The Gross Axle Weight Rating is the maximum
load limit for the front or the rear axle. This infor-
mation is located on the safety comliance sticker
located in the driver’s side door jamb.
For determining the compatibility of the tire and
vehicle load capabilities:
fPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 348.
The load capacity coefficient (e.g. “106”) is a mi-
nimum requirement.
The Gross Combined Weight Rating is the
maximum total weight rating of vehicle, passen-
gers, cargo and trailer.
The Vehicle Capacity Weight - Load Limit - is
the maximum total weight limit specified of the
load (passengers and cargo) for the vehicle. This
is the maximum weight of passengers and cargo
that can be loaded into the vehicle. This informa-
tion can be found on the tire pressure plate.
If a trailer is being towed, the trailer tongue weight
must be included as part of the cargo load.
The maximum loaded vehicle weight is the
sum of curb weight, accessory weight, vehicle ca-
pacity weight and production options weight.
The load rating is the maximum load that a tire
is rated to carry for a given inflation pressure.
The maximum load rating is the load rating for
a tire at the maximum permissble inflation pres-
sure.The cargo capacity is the permissible weight of
cargo, the substracted weight of passengers from
the load limit.
fNever exceed the permissible limits.
Gefahr!
Risk of personal injury or death.
Injuries are much more likely in an accident
if persons ride in the cargo area.
fPersons must ride only on the seats provided
for this purpose.
fMake sure that everybody fastens their safety
belts.
Risk of personal injury, loss of control and
damage to vehicle.
fNever exceed the specified axle loads.Overloa-
ding can shorten the service life of the tires
and car, as well as lead to dangerous vehicle
reactions and long braking distances. Damage
due to overloading is not covered by the vehic-le warranty.

Driving systems for off-road drivingSpecially adapted driving programs or power-
transmission and running-gear control systems
are available for off-road driving:
– Off-road program Low Range
–Off-road PSM
–Off-road ABS
– Center differential lock
– Rear differential lock
fPlease observe the chapter “POWER-TRANS-
MISSION AND RUNNING-GEAR CONTROL SYS-
TEMS” on Page 211.Before driving offTires
fCheck tread depth and tire pressure.
fCheck for damage and remove any foreign ob-
jects (e.g. stones) from the tread.
fReplace missing valve caps.
Rims
fReplace dented or damaged rims before
driving off road.
After driving off roadOff-road driving places a greater burden on the ve-
hicle than does normal driving on roads.
We recommend inspecting the vehicle after off-
road driving. Potential damage poses an accident
risk and impairs driving comfort. Damage on the
car is recognised in good time if the car is
checked.
Warning!
Car damage poses an accident risk for the
vehicle occupants and other road users.
fIn cases of doubt, have your vehicle checked
by your authorized Porsche dealer.
fExamine tires for signs of damage such as
cuts, tears, bulges or foreign objects stuck in
the tread. Replace a damaged tire if necessa-
ry.
fHave any damage to your vehicle repaired by an authorized Porsche dealer without delay.
Recommended procedure
fDeactivate Low Range.
fClean headlights and tail lights and check them
for signs of damage.
fClean the front and rear licence plates.fClean the tire tread with a jet of water and re-
move any foreign objects.
fClean wheels, wheel housings and the under-
body with a jet of water.
fCheck whether the car has picked up plant
parts or branches.
These materials increase the risk of fire and
can damage fuel lines, brake hoses, boots of
the axle joints and drive shafts.
fAfter off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, running gear and exhaust system for
signs of damage.
fAfter driving for an extended period through
mud, sand, water or substances with a similar
soiling effect, check the brake discs, brake
pads, wheels and axle joints and have them
cleaned.
fIf you experience severe vibrations after
driving off road, check the wheels for foreign
substances.
These substances can produce an imbalance
which might be responsible for the vibrations.
Removing these deposits may remedy the
problem.

Practical Tips, Minor Repairs

Notes on Minor RepairsTool kitThe tool kit is accommodated in the spare-wheel
well under the cover of the loadspace floor.
Tires/WheelsThe original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
For your safety remember the following:
– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original equip-
ment wheels, be sure that they conform to
Porsche specifications for your model.Only
tires with the same make and with the same
specification code (e.g. “N0“, “N1“...) can be
mounted.
– The use of wheel rims and wheel bolts that do
not meet specifications of the original factory
installed equipment will affect the safe opera-
tion of your vehicle.
– Before you plan on exchanging wheels, or
snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer.
Your dealer has the technical information nec-
essary to advise you which wheel rims and
wheel bolts are compatible with the original
factory installations.
Danger!
Risk of loss of control and serious personal
injury or death.
fIf while driving, your vehicle experiences a sud-
den vibration or ride disturbance, and/or you
suspect that possible damage to your tires or
vehicle has occurred, you should immediately
reduce your speed without excessive use of
the brakes.
fStop the vehicle as soon as possible, and in-
spect the tires.
If you cannot determine the cause for the dis-
turbance, have your vehicle towed to the near-
est Porsche or tire dealer to have your vehicle
or tire(s) inspected.
fContinuing to operate the vehicle without cor-
rection could result in a loss of control and se-rious personal injury.

Practical Tips, Minor Repairs
275
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.
