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 PRESSU-
RES, COLD” on Page 370.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 recommend-
ed in this Owner's Manual or on the tire-pressure
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 prop-
er pressure. Driving on a significantly under-inflat-
ed tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect the vehi-
cle’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”
on Page 100.When tires are warm, the tire pressure is in-
creased.
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
overheat and thus be damaged – even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting 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 207.

Vehicle Identification, Technical Data
Vehicle IdentificationWhen ordering spare parts or making inquiries,
please always quote the vehicle identification
number.Data bankThe data bank is located in the passenger com-
partment below the steering wheel. It contains all
important data about your car.This label contains the following information:
1. Vehicle Identification No.
2. Type/Type description
3. Engine code/Transmission code
4. Paint No./Interior
5. Optional equipment
A duplicate of this label is in your Maintenance
Booklet.
Note
The data bank cannot be reordered when lost or
damaged.
Vehicle identification numberIn accordance with Federal Safety Regulations,
the vehicle identification number of your car is lo-
cated at the bottom left of the windshield frame
and can be seen from the outside and in the lug-
gage compartment on the right in front of the tool
box.

Safety compliance stickerThe safety compliance sticker is your assurance
that your new Porsche complies with all applicable
Federal Motor Vehicle Safety Standards which
w e re i n e f f e c t a t t h e t ime the vehicle was manufac-
tured.
The sticker also shows the month and year of pro-
duction and the vehicle identification number of
your car (perforations) as well as the Gross Vehi-
cle Weight Rating and the Gross Axle Weight Rat-
ing.
Tire pressure plateThe tire pressure plate is fitted to the driver's
door.

The load capacity coefficient (e.g. “106”) and maximum speed code letter (e.g. “T”) for permitted top speed are
minimum requirements.
When fitting new tires or changing tires: Please observe the chapter “TIRES/WHEELS” on Page 285.
Tire and rim sizes
Extensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer
has information about approved tires and wheels and is happy to assist you.
If aftermarket tires and/or wheels are installed which are not approved by Porsche, the vehicle’s roadability and
handling characteristics might be impaired. Since Porsche has no data on such combinations, Porsche cannot
stand behind the safety or durability of these aftermarket combinations.
Please observe the chapter “SNOW CHAINS” on Page 296.
