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.
NOTE
During the tire's first revolution, some sealing
compound may spray out of the puncture
hole.
WARNING
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.
16. Check the inflation pressure on the air pres-
sure gauge.
•
If the pressure is under 1.3 bar (19 psi),
the tire is not sufficiently sealed. The vehi-
cle should not be driven. Call roadside
assistance to have the vehicle towed.
•
If the inflation pressure is higher than
1.3 bar (19 psi), the tire must be inflated
to the inflation pressure specified on the
tire pressure decal on the driver's side
door pillar (1 bar = 100 kPa = 14.5 psi). If
the inflation pressure is too high, use the
air release valve to release air.
NOTE
Replace the sealing compound bottle and
hose after use. Volvo recommends having
these replaced by an authorized Volvo work-
shop.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest author-
ized Volvo workshop to have the tire replaced/
repaired. Inform the workshop that the tire con-
tains sealing compound.
