When trouble arises
■If the tire is inflated to more than the specified air pressure
Disconnect the hose from the valve.
Disconnect the hose from the valv e, remove the air release cap from
the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, then turn
it off. Check that the air pressu re indicator shows the specified air pres-
sure. ( P. 471)
If the air pressure is under the designated pressure, turn the compres-
sor switch on again and repeat the inflation procedure until th e speci-
fied air pressure is reached.
■After a tire is repaired with the emergency tire puncture repai r kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire
pressure warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whos e expiry
date has already passed. Otherwise, repairs conducted using the emer-
gency tire puncture repair kit may not be performed properly. 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.
WARNING
■Caution while driving

Otherwise, the repair kit may fl
y out and break in events such as sud-
den braking, and may cause an accident.

causing death or serious injury.
●Do not use repair kit for tires that are different size than th e original
ones, or for any other purpose. If the tires have not been comp letely
