■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes
insufficient or the voltage temporar-
ily drops, the electric power steering
system warning light may come on
and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P. 4 4 6
If none of the tires are punctured:
Turn the engine switch off then turn
it to ON. Check if the tire pressure
warning light com es on or blinks.
If the tire pressure warning light
blinks for 1 minute then stays on
There may be a malfunction in the
tire pressure warning system. Have
the vehicle inspected by your Toyota
dealer immediately.
If the tire pressur e 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.399)
If the warning light d oes not turn off
several minutes af ter the initializa-
tion has been performed, have the
vehicle inspected by your Toyota
dealer immediately.
■The tire pressure warning light
may come on due to natural
causes
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this ca se, adjusting the
tire inflation pressure will turn off the
warning ligh t (after a few minutes).
■When a tire is replaced with a
spare tire
Vehicles with a co mpact spare tire:
The compact spare tire is not
equipped with a tire pressure warn-
ing valve and tran smitter. If a tire

4407-2. Steps to take in an emergency
goes flat, the tire pressure warning
light will not turn off even though the
flat tire has been replaced with the
spare tire. Replace the spare tire
with the repaired tire and adjust the
tire inflation pressure. The tire pres-
sure warning light will go off after a
few minutes.
Vehicles with a full- size spare tire:
The spare tire is also equipped with
a tire pressure warning valve and
transmitter. The tire pressure warn-
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 not turn off even
though the flat tire has been
replaced with the spare tire.
Replace the spare tire with the
repaired tire and adjust the tire infla-
tion pressure. The tire pressure
warning light will go off after a few
minutes.
■Conditions that the tire pres-
sure warning system may not
function properly
 P. 3 9 7
WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your Toy-
ota dealer.
The vehicle will become
extremely unstable during brak-
ing, and the ABS system may fail,
which could cause an accident
resulting in death or serious injury.
■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 assis t 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 fo rce 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 immedi-
ately.
●Vehicles with a compact spare
tire: If the tire pressure warning
light comes on even after tire
inflation 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.

When trouble arises
WARNING
■Maintenance of the tires
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer 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 infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)
As an added safe ty feature, your
vehicle has been equipped with a
tire pressure m onitoring system
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire
pressure telltale (tire pressure
warning light) when one or more
of your tires is significantly
under-inflated. Accordingly, when
the low tire pressure telltale (tire
pressure warning light) illumi-
nates, you should stop and check
your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a signifi-
cantly under-inflated tire causes
the tire to overheat and can lead
to tire failure. Under-inflation also
reduces fuel efficiency and tire
tread life, and may affect the vehi-
cle’s handling and stopping ability.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for pro per tire mainte-
nance, and it is the driver’s
responsibility to maintain correct
tire pressure, even if under-infla-
tion has not reach ed the level to
trigger illumination of the TPMS
low tire pressure telltale (tire pres-
sure warning light).
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not operating properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the te lltale will flash
for approximately one minute and
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the sys-
tem may not be ab le to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.
