Repair procedure
Note
The 911 GT2 is delivered with a tyre repair kit! A spare wheel or emergency wheel is not available!
•
The tyre repair kit (Tire Mobility System), a compressor and a pressure tester are located in the
luggage compartment! •
It is essential to observe the safety and operating instructions on the sealant bottle and on the
compressor!
•
Sealing the tyre with the tyre repair kit is only an emergency repair! •
Even if the tyre is sealed, it may only be used for short journeys in the event of an emergency and
must be replaced by a professional workshop immediately!
•
Avoid sharp acceleration and high speed on bends! The highest permissible speed is 80 km/h! •

Repair procedure
1. Take out sealant bottle and compressor. Shake sealant bottle well.
2. Screw the accompanying filler hose onto the bottle. The foil on the closure cap is automatically punctured.
3. Remove the valve cap from the tyre valve and unscrew the valve insert with the accompanying valve
insert driver and set it aside on a clean surface.
4. Remove the sealing plug from the filler hose, push the hose onto the tyre valve.
5. Hold the bottle with its base upwards and empty the entire contents of the bottle into the tyre. Then
remove the hose and screw the valve insert tightly into the tyre valve again.
CAUTION
Damage to the compressor (danger of overheating) in the case of excessively long operation!
Do not operate the compressor for longer than 6 minutes!
•
6. Screw the filler hose of the compressor onto the tyre valve, insert the plug into the cigarette lighter.
Pump tyre to 2.0 − 2.5 bar (read off pressure on pressure gauge).
7. If this air pressure cannot be reached, drive approx. 10 metres forward or backward with the vehicle,
so that the sealant can distribute itself in the tyre. Repeat pumping procedure.
Note
If the required air pressure still cannot be reached, the tyre is too badly damaged! •
