Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 441 and 364.

ON" position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all tires (including the spare tire) is as
specified on the tire and loading informa-
tion label. (See Checking tire inflation
pressure" on page 441 in Section 7−2.)
The light should go off a few minutes after
the tire pressure is adjusted.
If the warning light comes on after blink-
ing for 1 minute, the tire pressure warning
system may be malfunctioning. Contact
your Toyota dealer.
For details, see Tire pressure warning
system" on page 197 in Section 1−7. (o) Low Windshield Washer Fluid Level
Warning Light (for vehicles sold in
Canada)
The light warns that the windshield washer

The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if blowout or sudden air
loss should occur.

The tire pressure warning light comes on
when the engine switch is in ON" position
and goes off after a few seconds. This
means the tire pressure warning system is
operating properly. If the tire inflation pres-
sure becomes low, the light comes on
again. In this case, adjusting the tire infla-
tion pressure will turn off the light after a
few minutes. If the light comes on after
blinking for 1 minute, the tire pressure
warning system is not working properly.Indicatorstatus

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause 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 waring light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after a few minutes.
The spare tire is also equipped with the
tire pressure warning valve and transmit-
ter. The tire pressure waning light will turn
on if the tire inflation pressure of the
spare tire is low. If a tire goes flat, even
though the flat tire is replaced with the
spare tire, the warning light does not turn
off. Replace the spare tire with the re-
paired tire and adjust the proper tire infla-
tion pressure. The tire pressure warning
light will turn off after a few minutes.CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
