large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device
If tire position information is not cor-
rectly displayed due to the radio
wave conditions, the display may be
corrected by driving and changing
the radio wave conditions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with th e conditions
under which it was initialized. For
this reason, the system may give a
warning even if the tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.
When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire pressure warning system must
be initialized. (
P.430)
■When replacing the tires and
wheels
If the ID code of the tire pressure
warning valve and tr ansmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.

■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves and the tire pressure
warning valves could be bound.
●When replacing tire valve caps,
do not use tire valve caps other
than those specified.
The cap may become stuck.

performing initialization, the tire
pressure warning light blinks for
approximately 1 minute and then
illuminates.
If the inflation pressure of each tire
is still not displayed, have the vehi-
cle inspected by your Toyota dealer.
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
and transmitter, it is necessary
to register the ID code.
When registering the ID codes,
perform the following procedure.
With 4.2-inch display

control switches and select
“TPWS Setting”, and then
press “OK”.
5 Press or of the meter
control switches and select
“Identifying Each Wheel &
Position”. Then press and
hold “OK” until the tire pres-
sure warning light starts
slowly blinking 3 times.
The change wheel set mode is acti-
vated and registra tion is started.
Then a message will be displayed
on the multi-information display.
When registration is being per-
formed, the tire pressure warning
light will blink for approximately 1
minute then illuminate and “--” will
be displayed for the inflation pres-
sure of each tire on the multi-infor-
mation display.
6 Drive straight (with occa-
sional left and right turns) at
approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When registration is completed, the
tire pressure warning light will go off
and the inflation pressure of each
tire will be displayed on the multi-
WARNING
■When initializing the tire pres-
sure warning system
Do not initializing tire inflation
pressure without first adjusting
the tire inflation pressure to the
specified level. Otherwise, the tire
pressure warning light may not
come on even if the tire inflation
pressure is low, or it may come on
when the tire inflation pressure is
actually normal.

with the function to have ID
codes registered for a second
wheel set, for example a winter
set. You can register a second
wheel set by yourself or your
Toyota dealer.
After registration of a second
wheel set, either of these two
wheel sets can be selected for
usage with the tire pressure
warning system.
■Operating conditions for
the function
 This function will perform the
change of wheel set only if a
second wheel set has been
registered. If no second wheel
set has been registered, no
change will be made when
selecting this function in the
menu.
 Only a change between both
registered wheel set is possi-
ble, mixing between these
wheel sets is not supported.
■How to change between
wheel sets
1 Have the vehicle fitted with
the preferred wheel set.

second wheel set is being per-
formed. The tire pressure warn-
ing light will turn off and “--” will
be displayed for the inflation
pressure of each tire on the
multi-information display.
6 Initialize the tire pressure
warning system. ( P.427)
If the tire inflation pressure settings
for the installed ti res change, initial-
ization operations are required, but
if the tire inflation pressure settings
are the same, init ialization is not
required.

is complete when the tire pressure
warning light turns off and the infla-
tion pressure of each tire is dis-
played on the multi-information
display.

Use only Toyota wheel nuts
and wrenches designed for
use with your aluminum
wheels.
 When rotating, repairing or
changing your tires, check
that the wheel nuts are still
tight after driving 1000 miles
(1600 km).
 Vehicles with 17-inch or 18-
inch tires: Be careful not to
damage the aluminum wheels
when using tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels. 1
Turn the power switch off.
2 Open the glove box and slide
off the damper.
3 Push in each side of the
glove box to disconnect the
claws, and then slowly and
fully open the glove box while
supporting it.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine
Toyota wheels are used on your
vehicle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.

When trouble arises
■Conditions that the tire pres-
sure warning system may not
function properly
 P.425
WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your
Toyota dealer. The vehicle will
become extremely unstable
during braking, and the ABS sys-
tem 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 assist 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 force 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 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
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
Each tire, includi ng 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.)
