cated, or use any other object in
place of a fuse.
●Always use a genuine Toyota
fuse or equivalent.
Never replace a fuse with a
wire, even as a temporary fix.

There may be a malfunction in the
tire pressure warning system. Have
the vehicle inspected by your Toyota
dealer immediately.
If the tire pressure warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation pressure of each tire
and adjust them to the specified
level.
2 If the warning light does not turn
off even after several minutes
have elapsed, check that the
inflation pressure of each tire is
at the specified level and perform
initialization. ( P.424)
If the warning light does not turn off

ing light will turn on if the tire infla-
tion pressure of the spare tire is low.
If a tire goes flat, the tire pressure
warning light will no t turn off even
though the flat tire has been
replaced with the spare tire.
