as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this case, adjusting the
tire inflation pressure will turn off the
warning light (after a few minutes).
When a tire is replaced with a
■
spare tire
The temporary spare tire is not
equipped with the tire pressure
warning valve and transmitter. If a
tire goes flat, the tire pressure warn-
ing light will not turn off even though
the flat tire is replaced with the tem-
porary spare tire.
Replace the temporary spare tire
with the repaired tire and adjust the
proper tire inflation pressure. The
tire pressure warning light will turn
off after several minutes.

7-2. Steps to take in an emergency
When the electric power
■
steering system warning light
comes on
When the light comes on yellow,
the assist to the power steering is
restricted. When the light comes
on red, the assist to the power
steering is lost and handling oper-
ations of the steering wheel
become extremely heavy.
When steering wheel operations
are heavier than usual, grip the
steering wheel firmly and operate
it using more force than usual.
If the tire pressure warning
■
light comes on
Be sure to observe the following
precautions.
Failure to do so could cause a
loss of vehicle control and result
in death or serious injury.
Stop your vehicle in a safe place
●
as soon as possible.
Adjust the tire inflation pressure
immediately.
If the tire pressure warning light
●
comes on even after tire infla-
tion pressure adjustment, it is
probable that you have a flat
tire. Check the tires. If a tire is
flat, change it with the spare tire
and have the flat tire repaired by
the nearest Toyota dealer.
Avoid abrupt maneuvering and
●
braking.
If the vehicle tires deteriorate,
you could lose control of the
steering wheel or the brakes.
If a blowout or sudden air
■
leakage should occur
The tire pressure warning system
may not activate immediately.
