matter from the wheel con-
tact surface.
If foreign matter is on the wheel
WARNING
■Replacing a flat tire
●Do not touch the disc wheels or
the area around the brakes
immediately after the vehicle
has been driven.
After the vehicle has been
driven the disc wheels and the
area around the brakes will be
extremely hot. Touching these
areas with hands , feet or other
body parts while changing a tire,
etc. may result in burns.
●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.
• Never apply oil or grease to the wheel bolts or their contact sur-
face on the wheel .
Doing so may cause the wheel
bolts to be tightened exces-
sively, leading to damage to the
wheel bolts, the threaded por-
tion the wheel bolts install to ,
or the wheel.
Also, the wheel bolts may come
loose, possibly leading to the
wheel coming off, causing a
serious accident.
If oil or grease is attached to
either of these parts, remove it.
●When installing a wheel, use the
same wheel bolts that were
removed with the wheel. Also,
do not use any wheel bolts
other than Toyota Genuine
wheel bolts.
• If a wheel bolt hole in a wheel or the threads of a wheel bolt or
the wheel hub are deformed,
cracked, rusty or otherwise
damaged, have the vehicle
inspected by your Toyota
dealer.
■When tightening the wheel
bolts
Do not tighten the wheel bolts
excessively.
Doing so may cause the wheel
bolts, the threads of the wheel
hub, or the wheel to be damaged.
■Replacing a flat tire for vehi-
cles with power back door
In cases such as when replacing
tires, make sure to cancel the
power back door system
(  P.185). Failure to do so may
cause the back d oor to operate
unintentionally if the power back
door switch is accidentally
touched, resulti ng in hands and
fingers being caught and injured.

Maintenance and care
The recommended cold tire
inflation pressure and tire size
are displayed on the tire and
loading information label.
( P.555) Tire valve
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.

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.

Use only Toyota wheel bolts
and wrenches designed for
use with your aluminum
wheels.
 When rotating, repairing or
changing your tires, check
that the wheel bolts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent

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 vehi-
cle.
