is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the speci-
fied level.
• If tires not equipped with tire pres- sure warning valves and transmit-
ters are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• When driving near a TV tower, electric power plant, gas station,
radio station, large display, airport
or other facility 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 driving conditions.
For this reason, the system may
give a warning even if the tire pres-
sure does not reach a low enough
level, or if the p ressure 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. Have tire pressure
warning valve and transmitter ID
codes registered by your Toyota
dealer. ( P.318)
■Replacing 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.

Maintenance and care
■The tire pressure warning
system must be initialized
in the following circum-
stances:
When rotating the tires.
When the tire inflation pres-
sure is changed such as
when changing traveling
speed.
When changing the tire size.
When the tire pressure warning
system is initialized, the current
tire inflation pressure is set as
the benchmark pressure.
■How to initialize the tire
pressure warning system
1 Park the vehicle in a safe
place and turn the engine
switch off.
Initialization cannot be performed
while the vehicle is moving.
2Adjust the tire inflation pres-
sure to the specified cold tire
inflation pressure level.
Make sure to adjust the tire pres-
sure to the specifie d cold tire infla-
tion pressure level. The tire
pressure warning system will oper-
ate based on this pressure level.
3Turn the engine switch to
ON.
4 Press and hold the tire pres-
sure warning reset switch
until the tire pressure warning
light blinks slowly 3 times.
5 Wait for a few minutes with
the engine switch ON and
NOTICE
●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 ti re valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.
■To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repaired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer or other qualified service
shop as soon as possible. After
use of liquid sealant, make sure to
replace the tire pressure warning
valve and transmitter when repair-
ing or replacing the tire. (

then turn the engine switch
off.
■If you press the tire pressure
warning reset switch acciden-
tally
If initialization is performed, adjust
the tire inflation pressure to the
specified level and initialize the tire
pressure warning system again.
■Initialization procedure
●Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure.
Also, make sure the tires are cold
before carrying out initialization or
tire inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initializa-
tion, it is not necessary to press
the reset switch again as initializa-
tion will restart aut omatically when
the engine switch has been turned
to ON for the next time.
●If you accidentally press the reset
switch when initialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
■When initialization of the tire
pressure warning system has
failed
Initialization can be completed in a
few minutes. However, in the follow-
ing cases, the set tings have not
been recorded an d the system will
not operate properly. If repeated
attempts to record tire inflation pres-
sure settings are unsuccessful,
have the vehicle inspected by your
Toyota dealer.
●When operating the tire pressure
warning reset switch, tire pressure
warning light doe s not blink 3
times.
●After carrying out the initialization
procedure, the tir e pressure warn-
ing light blinks for 1 minute then stays on after driving for 20 min-
utes.
The tire pressure warning valve
and transmitter is equipped with
a unique ID code. When replac-
ing a tire pressure warning valve
and transmitter, it is necessary
to register the ID code. Have the
ID code registered by your Toy-
ota dealer.
■Registering ID codes
The ID codes of t he tire pressure
warning valve and transmitters for
two sets of whee ls can be regis-
tered.
It is not necessary to register the ID
codes when replacing normal tires
with snow tires, if the ID codes for
the wheels of both normal tires and
snow tires are registered before-
hand.
In addition to the set of tire pressure
warning system sensor ID codes ini-
tially registered to the vehicle, a sec-
ond set of ID codes can be
registered.
A second set of tire pressure warn-
ing system sensor ID codes can be
registered at your Toyota dealer.
WARNING
■When initializing the tire pres-
sure warning system
Do not operate the tire pressure
warning reset switch without first
adjusting the tire inflation pres-
sure to the specif ied level. Other-
wise, the tire pressure warning
light may not come on even if the
tire inflation press ure is low, or it
may come on when the tire infla-
tion pressure is actually normal.

WARNING
■When installing the tire
Failure to follow these precau-
tions could caus e the wheel nuts
to loosen and the tire to fall off,
resulting in death or serious injury.
●Never use oil or grease on the
wheel bolts or wheel nuts.
Oil and grease may cause the
wheel nuts to be excessively tight-
ened, leading to bolt or disc wheel
damage. In addition, the oil or
grease can cause the wheel nuts
to loosen and the wheel may fall
off, causing a serious accident.
Remove any oil or grease from
the wheel bolts or wheel nuts.
●Have the wheel nuts tightened
with a torque wrench to 89 ft•lbf
(120 N•m, 12.2 kgf•m) as soon
as possible after changing
wheels.
●Do not attach a heavily dam-
aged wheel ornament, as it may
fly off the whee l while the vehi-
cle is moving.
●When installing a tire, only use
wheel nuts that have been spe-
cifically designed for that wheel.
●If there are any cracks or defor-
mations in the bolt screws, nut
threads or bolt holes of the
wheel, have the vehicle
inspected by your Toyota
dealer.

Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check tire inflation pres-
sure every two weeks, or at least
once a month.
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.
■Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, observe the following:
●Check only when the tires are
cold.
If your vehicle has been parked for
at least 3 hours or has not been
driven for more than 1 mile or 1.5
km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to j udge if a tire is
properly inflated based only on its
appearance.
●It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight
should be placed so that the vehi-
cle is balanced.
WARNING
■Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire
and wheel
●Wheel deformation and/or tire
damage
