Tire sealing system – checking
inflation pressure
CAUTION
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
If your vehicle is equipped with the Tire
Pressure Monitoring System (TPMS), the
use of the sealing compound may lead to
incorrect tire pressure readings or in rare
cases, damage to the tire pressure sensor.
Use the tire sealing system to check and
adjust the damaged tire's inflation pres-
sure.
The tire sealing system can also be used to
check the tires' inflation pressure.
Stage 2: Checking inflation pressure
1. Connect the tire sealing system as
described in stage 1, see Tire sealing
system* – sealing hole (p. 317).
WARNING
If the pressure remains below 22 psi
(1.8 bar) after approximately seven
minutes, turn off the compressor. In this
case, the hole is too large to be sealed and
the vehicle should not be driven.
2. Refer to the inflation pressure table in this
chapter for the correct inflation pressure.
If the tire needs to be inflated, start the
tire sealing system’s compressor. If nec-
essary, release air from the tire by turning
the air release knob counterclockwise.
NOTE
Safely stow the tire sealing system in a
•
convenient place as it will soon be
used again to check the tire’s inflation
pressure.
10. Switch off the compressor and discon-
nect the electrical wire from the 12-volt
socket.
The empty bottle of sealing compound

CAUTION
11. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
CAUTION
After inflating the tires, always reinstall
the valve cap to help avoid damage to
the valve from dirt, gravel, etc.

WARNING
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.
•
If heavy vibrations, unsteady steering
behavior, or noises should occur while
driving, reduce speed and park the vehicle
in a safe place. Recheck the tire for
bumps, cracks, or other visible damage,
and recheck its inflation pressure. If the
pressure is below 19 psi (1.3 bar), do not
continue driving. Have the vehicle towed
to a trained and qualified Volvo service
technician.
12. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum
speed of 50 mph (80 km/h) to distribute
the sealing compound in the tire.
