Catalytic converter
The catalytic converter permits the subsequent treatment of the exhaust
gases thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil ⇒ page 185.
● Do not tow-start the vehicle; use the starter cables ⇒ page 273.
If you should notice misfiring, uneven running or loss of power when the ve-
hicle is moving, reduce speed immediately. Have the vehicle inspected by a
Specialised workshop. If this happens, unburnt fuel can enter the exhaust
gas system and escape into the atmosphere. The catalytic converter can al-
so be damaged by overheating.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used.

Practical information
● Start the vehicle engine and leave it running.
● Attach the connector ⇒ Fig. 146 9
to a 12 volt socket of the vehicle
⇒ page 117.
● Connect the air compressor with the ON/OFF switch ⇒ Fig. 146 8
.
● Keep the air compressor running until it reaches 2.0 to 2.5 bar
(29-36 psi / 200-250 kPa) ⇒
. Maximum operation time 8 minutes ⇒ .
● Disconnect the air compressor.
● If it is not possible to achieve an air pressure of 2.0 to 2.5 bar
(29-36 psi / 200-250 kPa), unscrew the tyre inflator tube from the tyre valve.
● Move the vehicle some 10 metres forwards or backwards so that the
sealant is evenly distributed in the tyre interior.
● Securely screw the compressor tyre inflator tube into the tyre valve and
repeat the inflation process.
● If the indicated pressure can still not be reached, the tyre is too badly
damaged. The tyre cannot be sealed with the anti-puncture kit. Do not con-
tinue driving. You should obtain professional assistance ⇒
.
● Disconnect the air compressor and unscrew the flexible inflator tube
from the tyre valve.
● When the tyre pressure is between 2.5 and 2.0 bars, immediately con-
tinue driving without exceeding 80 km/h (50 mph).
● After 10 minutes, Check the pressure again ⇒ page 259.
WARNING
When inflating the wheel, the air compressor and the inflator tube may
become hot.
● Protect hands and skin from hot parts.
● Do not place the hot flexible inflator tube or hot air compressor on
flammable material.
WARNING (Continued)
● Allow them to cool before storing the device.
● If it is not possible to inflate the tyre to at least 2.0 bars (29 psi /
200 kPa), the tyre is too badly damaged. The sealant is not in a good con-
dition to seal the tyre. Do not continue driving. You should obtain profes-
sional assistance.
CAUTION
Switch off the air compressor after a maximum of 8 operational minutes to
avoid overheating! Before switching on the air compressor again, let it cool
for several minutes.
Check after 10 minutes of driving
Screw the inflator tube ⇒ Fig. 146 5 again and check the pressure on the
gauge 6.
1.3 bar (19 psi / 130 kPa) and lower:
● Stop the vehicle! The tyre cannot be sealed sufficiently with the tyre mo-
bility set.
● You should obtain professional assistance ⇒
.
1.4 bar (20 psi / 140 kPa) and higher:
● Set the tyre pressure to the correct value again ⇒ page 210.
● Carefully resume your journey until you reach the nearest specialised
workshop without exceeding 80 km/h (50 mph).
● Have the damaged tyre replaced.
