7. Begin puncture repair
Connect the electrical cable to the closest
12 V socket and start the car.
NOTE
Make sure that none of the other 12 V
sockets is in use when the compressor is
operating.
WARNING
Do not leave children in the car without
supervision when the engine is running.
WARNING
Inhaling car exhaust fumes could result in
danger to life. Never leave the engine run-
ning in sealed areas or areas that lack suffi-
cient ventilation.
8. Start the compressor by flicking the
switch to position I (On).
When the compressor starts, the pressure
can increase up to 6 bar (88 psi), but the
pressure drops after about 30 seconds.
WARNING
Never stand next to the tyre when the
compressor is running. If cracks or uneven-
ness arise then the compressor must be
switched off immediately. The journey
should not be continued. Call roadside
assistance for recovery to a tyre centre.
Volvo recommends an authorised tyre cen-
tre.
9. Inflate the tyre for 7 minutes.
IMPORTANT
The compressor must not be operated for
longer than 10 minutes - risk of overheat-
ing.
WHEELS AND TYRES
10. Switch off the compressor to check the
pressure on the pressure gauge. Minimum
pressure is 1.8 bar (22 psi) and maximum
is 2.5 bar (36 psi). Release air using the
pressure reducing valve if the tyre pres-
sure is too high.
To access the pressure reducing valve, the
sealing fluid bottle must first be removed.
Remove the bottle in the following order:
1. Remove the air hose from the tyre
valve.
2. Remove the air hose from the bottle.
3. Remove the bottle from the compres-
sor.
4. Refit the air hose directly in the com-
pressor.
5. Refit the air hose to the tyre valve.
6. Release air using the pressure reducing
valve.
WARNING
If the pressure is below 1.8 bar (22 psi)
then the hole in the tyre is too big. The jour-
ney should not be continued. Call roadside
assistance for recovery to a tyre centre.
Volvo recommends an authorised tyre cen-
tre.
