TPC Tire Pressur e Monitoring
Function
Please observe the chapter ”TIRE PRESSU RE
FOR COLD TIRES” on page 299.
The Tire Pressure Monitoring continuously moni-
tors tire pressure and ti re temperature on all four
wheels and warns the driver when the tire pressure
is too low.
The display as well as the settings for the Tire
Pressure Monitoring take place on the on-board
computer. However, you must still adjust the tire
pressure on the wheel.
The driver is responsi ble for fi lling the tires
correctly and making the correct settings on
the on-board computer.
The Tire Pressure Monitoring offers the following
functions:
– Display of the actual tire pressure while the
vehicle is in motion
– Display of the deviation from the required
pressure (refilling pressure)
– Displa y of currently set t ire size and type
– Tire pressure warnings in t wo stages
Caution!
Despit e the advantages offe red by the Tire
Pressure Monitoring, it is still the driver’s
responsibility to update the corresponding
settings in the on-boa rd computer and
maintain the pressure in the t i res. Low tire
pressure reduces the road safety of the
vehicle and destroys the tire and whe el.
When a flat tire has been displayed, immediate-
ly stop in a suitable place and check the tires
for damage. If necessary, remedy the damage
with a tire sealant.
Do not by any means continue to drive with
defective tires.
Sealing the tire with tire sealant is only an
emergency repair, so you can drive to the next
authorized Porsche dealer. T he maximum
permit ted speed is 50 mph ( 80 km/h).
Do not drive with tires wh ose tire pressure
drops again in a short period of time. In cases
of doubt, have tires checked by an authorized
Porsche dealer.
Damaged tires must be immediately replaced
by an authorized Porsche dealer. Tire
repairs are not permissible under any
circumstances.
If the Tire Pressure Monitoring is defective
(e.g. defective wheel transmitter), contact
an authorized Porsche dealer immediat ely
and have the damage repaired. The tire
pressure will not be monitored by a defe ctive
Tire Pressure Moni toring.
Tires l ose air o ver time without a tire defect
being present. A tire pressure warning
will then appear in the on-board computer
display. C orrect the tire pressure at the next
opportunity.
The Tire Pressure Monitoring gives a warning
about tire damage due to natural pressure loss
as well as about a gradual loss of pressu re
due to foreign objects. The Tire Pressure
Monitori ng cannot warn you about tire damage
that occurs suddenly (e.g. flat tire due to
abrupt external effects).
