Warning!
Failure to follow these instructions may result
in serious personal injury to you or to bystan-
ders.
f If 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
motorists. Set the parking brake.
f Do not park your vehicle where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exhaust system could set
such materials on fire, thereby causing both
property damage and serious personal injury
or death.
A tire sealant and compressor with pressure
tester are located in the luggage compartment.
f Please see the safety and operating instruc-
tions on the special sealant bottle with a
special Porsche part number and on the
compressor – 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 trips in an
emergency.
The maximum permitted speed is 50 mph
(80 km/h).
f Do not use commercially available sealant or
tire inflating bottles.
Use only the tire sealant located in the luggage
compartment.
Warning!
Risk of accident, resulting in serious
personal injury or death.
f Have tires replaced by a specialist workshop
as soon as possible.
f Avoid hard acceleration and high cornering
speeds.
