Setting Tire Pressure Monitoring

Danger!
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
pressure increases rate of wear of the
affected tires.
Despite the advantages offered by Tire
Pressure Monitoring, it is not a substitute for
proper tire maintenance, and it is still the
driver's responsibility to update the settings
in the multi-purpose display and maintain the
correct tire pressure, even if under-inflation
has not reached the level to trigger illumina-
tion of Tire Pressure Monitoring low tire
pressure message. Low tire pressure
reduces the road safety of the vehicle and
destroys the tire and wheel.
f When a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary, remedy the
damage with tire sealant or fit the spare wheel.
f Do not by any means continue to drive with
leaking tires.
f Sealing the tire with the tire sealant is only an
emergency repair so you can drive to the next
authorized Porsche dealer.
The maximum permitted speed is 50 mph
(80 km/h).
f Defective tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.
f Do not drive with tires whose tire pressure
drops again in a short period of time. Have
tires checked by an authorized Porsche dealer.
f If Tire Pressure Monitoring is defective (e.g.
defective wheel transmitters), contact an
authorized Porsche dealer immediately and
have the damage repaired.
The tire pressure will not be monitored by
defective Tire Pressure Monitoring.
For information on warning messages on the
multi-purpose display: Please see the chapter
"OVERVIEW OF WARNING MESSAGES" on
Page 149.
f Tire Pressure Monitoring gives a warning about
tire damage due to insufficient tire pressure as
well as about a gradual loss of pressure due to
foreign objects. Tire Pressure Monitoring
cannot warn you about tire damage that
occurs suddenly (e.g. flat tire due to acute
external effects).
