■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 drive train
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 the
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. ( P.590)
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 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 must be installed.
( P.488, 500)
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.
Wheel selection
WARNING
■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.
5007-3. Do-it-yourself maintenance
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 1600 km (1000 miles).
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 hammer when
balancing your wheels.

■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 autho- rized 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.
●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
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( P.492)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a com-pact spare tire (vehicles with com-
pact spare tire)
The compact spare tire is not equipped with a tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off even though the flat tire has been
replaced with the spare tire. Replace the spare tire with the standard tire and adjust the tire inflation pressure. The tire
pressure warning light will go off after a few minutes.
