den braking, sudden accelera-
tion and sharp turns, drive
carefully at under 80 km/h (50
mph) to the nearest Toyota
dealer that is less than 100 km
(62 miles) away for tire repair or
replacement.
When having the tire repaired or replaced, make sure to tell any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer that the sealant is injected.
■If the tire is inflated to more than the specified air pressure
1 Disconnect the hose from the valve.
2 Install the air release cap to the end of the hose and push the protrusion
on the air release cap into the tire valve to let some air out.
3 Disconnect the hose from the valve,
remove the air release cap from the hose and then reconnect the hose.
4 Turn the compressor switch on and wait for several seconds, and then
turn it off. Check that the air pressure indicator shows the specified air pressure. ( P.355)
If the air pressure is under the desig- nated pressure, turn the compressor switch on again and repeat the inflation
procedure until the specified air pres- sure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emer- gency tire puncture repair kit, the valve should be replaced.
■After a tire is repaired with the
emergency tire puncture repair kit
●The tire pressure warning valve and
transmitter should be replaced.
●Even if the tire inflation pressure is at
the recommended level, the tire pres- sure warning light may come on/flash.
WARNING
■Do not drive the vehicle with a
flat tire
Do not continue driving with a flat tire. Driving even a short distance with a
flat tire can damage the tire and the wheel beyond repair.
