13 To inject the sealant and 
inflate the tire, turn the com-
pressor switch on.
14 Inflate the tire until the rec-
ommended pressure is 
reached.
The sealant will be injected 
and the pressure will spike to 
between 44 psi (300 kPa, 3.0 
kgf/cm
2 or bar) and 58 psi 
(400 kPa, 4.0 kgf/cm
2 or bar),  then gradually decrease.
The air pressure gauge will 
display the actual tire inflation 
pressure about 1 to 5 min-
utes after the switch is turned 
on.
• Turn the compressor switch off 
and then check the tire inflation 
pressure. Being careful not to 
over inflate, check and repeat the 
inflation procedure until the speci-
fied tire inflation pressure is 
reached.
• The tire can be in flated for about 
5 to 20 minutes (depending on 
the outside temperature). If the 
tire inflation press ure is still lower 
than the specified point after infla-
tion for 25 minutes, the tire is too 
damaged to be repaired. Turn the 
compressor switch off and con-
tact your Toyota dealer.
• If the tire inflation pressure  exceeds the spec ified air pres-
sure, let out some  air to adjust the 
tire inflation pressure. ( P.535)
15With the compressor switch 
off, pull out the power plug 
from the power outlet socket 
and then disconnect the hose 
from the valve on the tire.
Some sealant may leak when the

repaired tire.
17Attach the air release cap to  the end of the hose.
If the air release cap is not 
attached, the sealant may leak and
