Flat Tire
Warning!
Failure to follow these instructions may result
in serious personal injury to you or to by-
standers.
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 motor-
ists. Set the parking brake.
f Do not park your vehicl e 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 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).
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.

onto the filler bottle.
The filler bottle is now open.

7. Remove valve insert E from the tire valve with
valve turner D.
Keep the valve insert in a clean and dry place.
8. Remove plug C of the filler hose B.
9. Push filler hose onto the tire valve.
10.Hold filler bottle higher than the level of the tire valve and press it together forcefully until the
bottle is completely emptied into the tire.
11.Pull filler hose off the tire valve.
12.Twist the valve insert fi rmly into the tire valve
using the valve turner.
13.Connect the compressor to the cigarette light- er and inflate the tire to the prescribed tire
pressure.
Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on Page 277.
14.Screw valve cap onto the tire valve.
15.Check the tire pressure after driving for around 10 minutes.
If the tire pressure is less than 22 psi (1.5 bar),
do not continue driving.
If a value of more than 22 psi (1.5 bar) is indi-
cated, correct the pressure to the prescribed
value. 16.Please consult your authorized Porsche
dealer.
Note on operation for vehicles with Tire Pressure
Monitoring
f On vehicles with Tire Pressure Monitoring, the
settings on the on-board computer must be
updated after the wheel change.
Please see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 147.
Care Instructions
After drying, any sealan t that emerges can be
peeled off like a film.

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 st and behind the safety or durability of these aftermarket combinations.
Snow chains Can be mounted only on the rear wheels; maximum speed 30 mph/50 km/h. Use only Porsche authorized fine-link
cross-type or edge chains. Snow chain clearance can be guaranteed only with the tire + rim combination marked*
without spacers. Please see the chapter “SPACERS” on Page 243.
