ing valve and transmitter. If a tire
goes flat, the tire pressure warning
light will not turn o ff even though the
flat tire has been replaced with the
spare tire. Replace the spare tire
with the standard tire and adjust the
tire inflation pressure. The tire pres-
sure warning light will go off after a
few minutes.

WARNING
■If a warning light comes on or
a warning buzzer sounds
when a warning message is
shown on the multi-informa-
tion display
*
Check and follow the message
shown on the multi-information
display.
Failure to do so m ay result in
death or serious injury.
*: Warning lights illuminate in red
or yellow and the warning
buzzer beeps on ce or sounds
continuously.
■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.
If the steering wheel becomes
heavier than usual when operat-
ing, hold firmly and operate using
more force than usual.
■If the tire pr essure warning
light comes on ( vehicles with
tire pressure warning system)
Be sure to observe the following
precautions. Failure to do so
could cause a loss of vehicle con-
trol 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 dete-
riorate, you could lose control of
the steering wheel or the
brakes.
■If a blowout or sudden air
leakage should occur (vehi-
cles with tire pressure warn-
ing system)
The tire pressure warning system
may not activate immediately.

WARNING
■Maintenance of the tires
(vehicles with tire pressure
warning system)
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 pres-
sure warning light) illuminates,
you should stop and check your
tires as soon as possible, and
inflate them to the proper pres-
sure. Driving on a significantly
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 abil-
ity.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for proper tire mainte-
nance, and it is the driver’s
responsibility to m aintain correct
tire pressure, even if under-infla-
tion has not reached the level to
trigger illumination of the TPMS
low tire pressure te lltale (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 (vehicles with tire
pressure warning system)
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.
If a warning message
is displayed
The multi-information dis-
play shows warnings of sys-
tem malfunctions,
incorrectly performed oper-
ations, and messages that
indicate a need for mainte-
nance. When a message is
shown, perform the correc-
tion procedure appropriate
to the message.
If a warning message is dis-
played again after the appro-
priate actions have been
performed, contact your
Toyota dealer.
