in serious personal injuries to you or to by-
standers.
fIf you have a flat tire, move a safe distance off
the road. Turn the emergency flasher on and
use other warning devices to alert other motor-
ists. Set the parking brake.
fDo not park your vehicle where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exaust system could set
such materials on fire, thereby causing both
property damage and severe or fatal physical injury.
A tire sealant and compressor with pressure
tester are located in the toolbox in the luggage
compartment.
fPlease observe the safety and operating in-
structions on the special sealant bottle with a
special Porsche part number and on the com-
pressor – these are essential.Important note
Sealing the tire with the tire repair kit is only
an emergency repair. Even with the tire air-
tight, it may be used only for short journeys
in an emergency.
The maximum permitted speed is 50 mph
(80 km/h).
fDo not use commercially available sealant or
tire inflating bottles.
Use only the tire sealant located in the tool box
in the luggage compartment.
Warning!
Risk of accident.
fHave tires replaced by a specialist workshop
as soon as possible.

Wheel Securing Bolts The wrench socket for the wheel securing bolts is
in the tool pocket.
To loosen or tighten the wheel bolt with anti-theft
protection, a wrench socket with the appropriate
coding must be used between the wheel bolt and
the wheel-bolt spanner.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
If the wheels have to be removed at the workshop,
please do not forget to hand over the wrench
socket for the wheel securing bolts along with the
car key.
