elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization.
( P.483)
■The tire pressure warning light may
come on due to natural causes (vehicles with a tire pressure warn-
ing system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres-

WA R N I N G
●Vehicles with a compact spare tire
and full-size spare tire: If the tire
