When trouble arises
to be repaired. Turn the compres-
sor switch off and contact your Toy-
ota dealer.
If the tire inflation pressure exceeds
the specified air pressure, let out
some air to adjust t he tire inflation
pressure. ( P.498, 529)

off, disconnect the hose from
the valve on the tire and then
pull out the power plug from
the power outlet socket.
Some sealant may leak when the
hose is removed.

cannot be repaired. Contact
your Toyota dealer.
If the tire inflation pressure is
19 psi (130 kPa, 1.3
kgf/cm

ignated pressure, turn the compres-
sor switch on again and repeat the
inflation procedure until the speci-
fied air pressure is reached.
■The valve of a tire that has been
repaired (vehicles without a tire
pressure warning system)
After a tire is repaired with the emer-
gency tire puncture repair kit, the
valve should be replaced.
■After a tire is re paired with the
emergency tire puncture repair
kit (vehicles with a tire pressure
