If the low tire pressure warning light
comes on or blinks, do the following.
If the warning light comes on:
Stop your vehicle in a safe place as
soon as possible and check that the
inflation pressure of all tires (including
the spare tire) is as specified on the
tire and loading information label. (See
"Checking tire inflation pressure" on
page 381 in Section 7- 2.) If the warning
light comes on even after tire inflation
pressure adjustment, you may have a
flat tire. If you have a flat tire, replace
it with the spare tire. For details, see
"If you have a flat tire" on page 335 in
Section 4.
The warning light goes off a few minutes
after air is put into the deflated tire.
This warning light may turn on due to
natural causes such as natural air leaks
or tire pressure changes caused by tem-
perature. In this case, adjusting the tire
pressure will turn off the warning light.

CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Depending on the conditions, re-
D
duce to an appropriate speed as
soon as possible.
Adjust the tire pressure to the spe-
D
cified level as soon as possible.
Avoid abrupt steering wheel maneu-
D
vering and braking. Tire deteriora-
tion may reduce steering wheel con-
trol and brake effectiveness. This
may lead to serious injury or death.
The tire pressure warning system
D
may not activate immediately if sud-
den bursts of air leakage occur.
NOTICE
z Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
z When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected by
the installation or removal of tires.
z The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure
check the air pressure in the tires
on a regular basis.
z When the tires must be replaced,
replace the grommets for air pres-
sure sensors as well.
