WHEELS AND TIRES

8. Start the compressor by moving the switch to
the I (On) position.
WARNING
Never stand next to a tire being inflated with
the compressor. If cracks, bulges, etc. form on
the tire, switch off the compressor immedi-
ately. The vehicle should not be driven. Call
roadside assistance to have the vehicle towed
to a workshop for inspection/replacement of
the tire. Volvo recommends an authorized
workshop.
NOTE
When the compressor first starts, air pressure
may temporarily increase up to 6 bar (88 psi)
but should decrease again after approxi-
mately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor
should never be used for more than
10 minutes at a time.

10. Switch off the compressor and check the
inflation pressure using the air pressure
gauge. The inflation pressure should be
between 1.8 bar (22 psi) and 3.5 bar
(51 psi). If the inflation pressure is too high,
use the air release valve to release air.
WARNING
If pressure falls below 1.8 bar (22 psi), the
hole in the tire may be too large. The vehicle
should not be driven. Call roadside assistance
to have the vehicle towed to a workshop for
inspection/replacement of the tire. Volvo rec-
ommends an authorized workshop.
11. Switch off the compressor and remove the
electrical cable.
12. Unscrew the hose from the tire's valve and
screw the valve cap back on.
NOTE
• After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.
•
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.
13. Put the protective hose cover onto the hose
to help prevent leakage of any residual seal-
ing compound. Return the equipment to the
cargo compartment.
14. Immediately drive the vehicle at least 3 km
(2 miles) at a maximum speed of 80 km/h
(50 mph) to allow the sealing compound to
seal the tire, and then recheck the inflation
pressure.
WARNING
During the tire's first revolution, some sealing
compound may spray out of the puncture
hole. Before driving away, make sure that no
one is near the vehicle who could be sprayed
with sealing compound. Make sure no one is
within 2 meters(7 feet) of the vehicle.
15. Rechecking the inflation pressure
Connect the hose to the tire's valve and
screw the hose connector onto the valve as
far as possible. The compressor must be
switched off.
