WHEELS AND TYRES

6. Unscrew the tyre's dust cap and screw in the
air hose's valve connection to the bottom of
the thread on the tyre's air valve.
Check that the pressure reducing valve on
the air hose is fully screwed in.
7. Connect the electrical cable to the closest
12 V socket and start the car.
NOTE
Make sure that none of the other 12 V sock-
ets is in use when the compressor is operat-
ing.
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 running
in sealed areas or areas that lack sufficient
ventilation.
8. Start the compressor by flicking the switch to
position I (On).
WARNING
Never stand next to the tyre when the com-
pressor is running. If cracks or unevenness
arise then the compressor must be switched
off immediately. The journey should not be
continued. Call roadside assistance for recov-
ery to a tyre centre. Volvo recommends an
authorised tyre centre.
NOTE
When the compressor starts, the pressure
can increase up to 6 bar (88 psi) but the
pressure drops after approximately
30 seconds.
9. Inflate the tyre for 7 minutes.
IMPORTANT
The compressor must not be operated for
longer than 10 minutes - risk of overheating.
10. Switch off the compressor to check the pres-
sure on the pressure gauge. Minimum pres-
sure is 1.8 bar (22 psi) and maximum is
3.5 bar (51 psi). Release air using the pres-
sure reducing valve if the tyre pressure is too
high.
WARNING
If the pressure is below 1.8 bar (22 psi) then
the hole in the tyre is too big. The journey
should not be continued. Call roadside assis-
tance for recovery to a tyre centre. Volvo rec-
ommends an authorised tyre centre.
11. Switch off the compressor and detach the
electrical cable.
12. Unscrew the air hose from the tyre valve and
refit the dust cap on the tyre.
NOTE
•
After a tyre has been inflated, always refit
the dust cap in order to avoid damage to
the valve from gravel, dirt, etc.
•
Only use plastic dust caps. Metal dust
caps can rust and become difficult to
unscrew.
13. Fit the protective cap on the air hose in order
to avoid leakage of the remaining sealing
fluid. Place the equipment in the cargo area.
