Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 427, 442
If the tire is not punctured:
Check the tire inflation pressure after the tire temperature has lowered suffi-
ciently. Adjust the inflation pressure to the appropriate level and carry out ini-
tialization. ( P. 3 7 4 )
■ The tire pressure warning light may come on due to natural causes
