tion or remains on for more than 6
seconds.
The light comes on while driving.
(l) Low Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (including the
spare tire) is low. The light comes on
when the ignition key is turned to the
“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” in Section 7 −2.) The light should
go off a few minutes after the tire pres-
sure is adjusted.
If the warning light blinks, the tire pres-
sure warning system may be malfunction-
ing. Contact your Toyota dealer. For details, see “Tire pressure warning
system” in Section 1
−7.
(m) Automatic Transmission Fluid Temperature Warning Light
(four −wheel drive models)
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance.
(n) Low Windshield Washer Fluid Level Warning Light
This light warns that the windshield wash-
er fluid level is too low. Add washer fluid
at your earliest opportunity. (For instruc-
tions, see “Adding washer fluid” in Section

The tire pressure warning system is de-
signed to provide warning when tire
inflation pressure of one or more of
your tires (including the spare tire) is
low. The low tire pressure warning light
comes on to inform you that low tire
inflation pressure may hamper driving.

LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
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” in
Section 7 −2.) If the warning light comes
on even after tire inflation pressure ad-
justment, 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” 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-
duce to an appropriate speed as
soon as possible.
Adjust the tire pressure to the spe-
cified level as soon as possible.
Avoid abrupt steering wheel maneu-
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
may not activate immediately if sud-
den bursts of air leakage occur.
NOTICE
Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
 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.
 The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
 When the tires must be replaced,
replace the grommets for air pres-
sure sensors as well.
If the warning light blinks:
The tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
SYSTEM MALFUNCTION
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
A radio set to similar frequencies is in
use.
A lot of snow or ice covers the ve-
hicle, in particular, around the wheels
or wheel housings.
The tires are not equipped with an air
pressure sensor.
Snow tires or tire chains are used.
Non −genuine Toyota wheels are used.
The sensor battery is expired.
Radio waves from the air pressure sen-
sor installed on the spare tire cannot
be received.

CAUTION
The use of non −genuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
The use of different type of tires
with genuine wheels may also
cause the malfunction of the sys-
tem.
CAUTION
When the tire pressure monitoring
system warning light is lit, one or
more of your tires is significantly un-
der −inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper pres-
sure as indicated on the vehicle’s tire
information placard. Driving on a sig-
nificantly under −inflated tire causes
the tire to overheat and can lead to
tire failure. Under− inflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ab ility. Each tire,
including the spare, should be
checked monthly when cold and set
to the recommended inflation pres-
sure as specified in the vehicle plac-
ard and owner ’s manual.

When initializing the system, make sure
the low tire pressure warning light blinks
three times. If the warning light does not
blink three times, initialization failed and
the tire pressure warning system will not
function properly. In this case, initialize
the system again.
Do not push the reset switch without ad-
justing the tire inflation pressure to the
specified level. Otherwise, the low tire
pressure warning light may not come on
even if the tire pressure is low, or it may
come on when the tire inflation pressure
is actually normal.
If you push the reset switch while the
vehicle is moving, initialization is not per-
formed.
If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Toyota dealer.
