WARNING

■

When inspecting or replacing tires

Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.

●

Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.

●

Do not use tire sizes other than those recommended by Toyota.

●

Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).

●

Do not mix summer, all season and snow tires.

●

Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.

■

When initializing the tire pressure warning system (if equipped)

Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

NOTICE

■

Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with the tire pressure warn-
ing system)

●

When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer as the tire pressure warning
valves and transmitters may be damaged if not handled correctly.

●

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 tire 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
(vehicles with the tire pressure warning system)

When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer or other qualified service shop as soon as possible. After use of liq-
uid sealant, make sure to replace the tire pressure warning valve and trans-
mitter when repairing or replacing the tire. (

■

Driving on rough roads

Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.

■

If tire inflation pressure of each tire becomes low while driving

Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure

■

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 drive train

If a tire needs frequent refilling, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

■

Instructions for checking tire inflation 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 and 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 appear-
ance.

●

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.

●

Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

Make sure to maintain the proper tire inflation pressure. Tire
inflation pressure should be checked at least once per month.
However, Toyota recommends that tire inflation pressure be
checked once every two weeks. (

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 damage

●

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.

7-3. Do-it-yourself maintenance

Wheels

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.
Toyota does not recommend using the following:

: Conventionally referred to as “offset”.

●

Wheels of different sizes or types

●

Used wheels

●

Bent wheels that have been straightened

●

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.

●

When balancing your wheels, use only Toyota genuine balance
weights or the equivalent. If clip-on balance weights are being
used, use a plastic or rubber hammer to install the weight.

If a wheel is bent, cracked or heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.

■

When replacing wheels (vehicles with the tire pressure warning system)

The wheels of your Toyota 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. 602)

WARNING

■

When replacing wheels

●

Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.

●

Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.

■

When installing the wheel nuts

●

Be sure to install the wheel nuts with the tapered ends facing inward.
(



P. 710)

Installing the nuts with the tapered ends facing outward can cause wheel
to break and eventually cause the wheel to come off while driving, which
could lead to an accident 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 an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.

■

Use of defective wheels prohibited

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 (vehicles with
the tire pressure warning system)

●

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 purchase 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.
