■Warning performance of the tire
pressure warning system (Set-
ting using the current tire infla-
tion pressure)
●When performing the tire pressure
setting using the current tire infla-
tion pressure, the warning timing
of the tire pressure warning sys-
tem will vary according to the con-
ditions under which tire pressure
setting was performed. Therefore,
a warning may be output even if
the tire inflation pressure drops
slightly or if the ti re inflation pres-
sure increases above that when
the tire inflation pressure was set.
●Make sure to per form the tire
pressure setting p rocedure after
adjusting the tire inflation pres-
sure. Also, make sure the tires are
cold before performing the tire
pressure setting procedure or
adjusting the tire inflation pres-
sure.
■Tire inflation pressure setting
procedure (Setting using the
current tire inflation pressure)
●If the power switch is turned off
while setting the tir e inflation pres-
sure, the next time the power
switch is turned to ON, the setting
procedure will resume and it will
not be necessary to restart the
procedure.
●If the tire inflation pressure setting
procedure is started unnecessar-
ily, adjust the tire inflation pres-
sure to the specified level with the
tires cold and then perform setting
by selecting a specified tire infla-
tion pressure, or perform the tire
inflation pressure setting proce-
dure with the curren t tire inflation
pressure.
■If the tire inflation pressure can-
not be set properly
●Normally, the tire inflation pres-
sure setting pro cedure can be
completed in 2 or 3 minutes.
●If the tire pressur e warning light

may not have started. Perform the
procedure again from the begin-
ning.
●If tire inflation pressure setting
procedure cannot be completed
after performing the above proce-
dure, contact your Toyota dealer.
■When the registering ID
codes
The tire pressure warning valve
and transmitter is equipped with
a unique ID code.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer.
■How to registration ID code

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 ti re inflation pres-
sure every two week s, or at least
once a month.
Tire inflation pressure
Make sure to maintain the
proper tire inflation pres-
sure. Tire inflation pressure
should be checked at least
once per month. However,
Toyota recommends that
tire inflation pressure be
checked once every two
weeks. ( P.555)

■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result in the following:
●Reduced electricity consumption
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
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 tha n 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 judge 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 vehicle 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
●Greater possibi lity of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing tire inflation pressure
Be sure to put the tire valve caps
back on.
If a valve cap is no t installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.

Maintenance and care
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
 Wheels of different sizes or
types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are
equipped with tire pressure warning
valves and transmitters that allow
the tire pressure warning system to
provide advance warning in the
event of a loss in tire inflation pres-
sure. Whenever wheels are
replaced, tire pressure warning
valves and transmitters must be
installed. ( P.476)
Wheels
If a wheel is bent, cracked
or heavily corroded, it
should be replaced. Other-
wise, the tire may separate
from the wheel or cause a
loss of handling control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended in the Owner’s Manual,
as this may result in a loss of
handling control.
●Never use an inner tube in a
leaking wheel which is designed
for a tubeless tire. Doing so may
result in an accident, causing
death or serious injury.
■Wheel bolts
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Do not over tighten.
●Never use oil or grease on the
wheel bolts. Oil and grease may
cause the wheel bolts to be
excessively tightened, leading
to bolt or disc wheel damage. In
addition, the oil or grease can
cause the wheel bolts to loosen
and the wheel may fall off, caus-
ing a serious accident. Remove
any oil or grease from the wheel
bolts.
●If there are any cracks or defor-
mations in the wheel bolts, or if
the surface treatment becomes
worn, have the wheel bolts
replaced at your Toyota dealer.
Failure to follow these precau-
tions could cause the wheel
bolts to loosen and the tire to fall
off, resulting in death or serious
injury.
■Use of defective wheels pro-
hibited
Do not use cracke d or deformed
wheels.
Doing so could cause the tire to
leak air during driving, possibly
causing an accident.
