■When installing the tire
Failure to follow these precautions
could cause 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 tightened, 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 seri-
ous accident. Remove any oil or
grease from the wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 120 N•m (12.2
kgf•m, 89 ft•lbf) as soon as possible
after changing wheels.
●Do not attach a heavily damaged
wheel ornament, as it may fly off the wheel while the vehicle is moving.
●When installing a tire, only use wheel nuts that have been specifi-
cally designed for that wheel.
●If there are any cracks or deforma-
tions in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres-
sure 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 any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
■Instructions for checking tire infla-
tion pressure
When checking tire inflation pressure, 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 1.5 km or 1 mile, 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 pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is
balanced.Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks.
WA R N I N G
■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 serious 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 dam-
age
●Greater possibility of tire damage
while driving (due to road hazards, expansion joints, sharp edges in the
road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back
on. If a valve cap is not 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, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
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 pressure. Whenever wheels are
replaced, tire pressure warning valves and transmitters mu st be installed.
( P.304)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.

WA R N I N G
■When replacing wheels
●Do not use wheels that are a differ-
ent size from those recommended in the Owner’s Manual, as this may
result in a loss of handling control.
●Never use an inner tube in a leak-
ing wheel which is designed for a
tubeless tire. Doing so may result in
an accident, causing death or seri- ous injury.
■When installing the wheel nuts
Never use oil or grease on the wheel
bolts or wheel nuts. Oil and grease
may cause the wheel nuts to be excessively tightened, 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 an accident and resulting
in death or serious injury. Remove any oil or grease from the wheel bolts
or wheel nuts.
■Use of defective wheels prohib-
ited
Do not use cracked or deformed wheels. Doing so could cause the tire
to leak air during driving, possibly
causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure
to have tires serviced by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer or other qualified service shop. In addition, make sure to pur-
chase your tire pressure warning
valves and transmitters at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
